JR R1221 Receiver
The R1221 receiver combines one internal with three remote
receivers, offering superior path diversity. The radio system
simultaneously transmits on two frequencies, creating up to
four RF paths on two different 2.4GHz channels. This multi path
redundancy, plus the fact that each of the 4 receivers are located
in different locations throughout the aircraft, exposes each to
a different RF environment creating a superior RF link in all
conditions. The JR R1221 allows an optional Flight Log data
recorder (JRPA145) to be used. The flight log can be plugged
into the data port of the receiver to provide RF link data of the
previous flight, allowing the confirmation of the operational
performance of the system receiver antenna.

Charging
Transmitter/Receiver
Note: It is imperative that you fully charge both the
transmitter and the receiver battery packs prior to each
flying session and that you check the condition of the
receiver battery between each flight using a reliable battery
tester with a built-in load. The included wall charger
charges at a 250mA rate. In order to fully charge the
included batteries, it’s necessary to leave the charger and
batteries hooked up to the included wall charger for 8–10
hours.
An optional fast charger can be used to charge both the
transmitter and receiver batteries, however, it’s imperative that
the batteries are properly charged and the charge condition
be checked prior to flight. “False Peaking” is a common
occurrence with many fast chargers/ batteries, giving an
indication that the battery is fully charged when in fact the
battery is only partially charged. False Peaking can lead to
disastrous results and it is the pilot’s responsibility to verify the
charge condition of the batteries before every flight. (Also see
Receiver Power Requirements page I-26.)
Using the Included Charger
The pilot lamps should always be on during the charging
operation. If not, check to make sure that both the transmitter
and receiver are switched off.
Do not use the charger for equipment other than JR. The
charging plug polarity may not be the same. Equipment damage
can result.
Do not use other manufacturers’ after-market accessories that
plug into the transmitter’s charging jack if you are unsure of
the polarity compatibility with your radio. Seek expert advice to
avoid possible damage.
During the charging operation, the charger’s temperature is
slightly elevated.

JR Transmitter Charging
The center pin on all JR® transmitters is negative. Therefore,
the center pin on all JR chargers is negative, not positive. This
is different from many other manufacturers’ chargers and radio
systems. Beware of improper connections based on “colorcoded” wire leads, as they may not apply in this instance. You
must make sure that the center pin of your JR transmitter is
always connected to the negative pole for correct polarity.

Control Stick Tension Adjustment
Stick tension adjustments are accessible through covers that
are located on the back of the transmitter (see photo). Carefully
pull back the cover or remove the grip to access the gimbals’
tension screws and then, using a small Phillips screwdriver,
adjust each gimbal’s tension screw for the desired tension
(counterclockwise to loosen stick tension; clockwise to tighten
stick tension).
Advanced Digital Trims
The 12X features Advanced digital trims. On the Normal display
screen, if a trim lever is moved, the screen will automatically
change to display the graphic position for the trim being
adjusted. The 12X Aileron, Elevator and Rudder trim levers and
the right and left side levers feature an audible center trim beep.
This is helpful in determining the trim lever’s center position
during flight. In addition, the frequency of each trim step
changes from full right/up to full left/down, allowing the pilot to
be aware of the general trim position audibly without looking at
the transmitter.
By using the Trim System Function Code 83 located in the
System Mode, the amount of travel per each trim step can be
adjusted as needed to match your specific application.
Please note that when the 12X transmitter is turned off, the trim
values are stored in memory and are recalled when the system
is turned back on.
Control Stick Length
Use a 2mm Allen wrench to unlock the setscrew to adjust
the stick length. Turn the wrench counterclockwise to loosen
the screw. Then, turn the stick clockwise to shorten or
counterclockwise to lengthen the overall stick length. After the
control stick length has been adjusted to suit your flying style,
tighten the 2mm setscrew. If you desire longer sticks, JR offers
a stick (JRPA047) that is approximately one inch longer than
standard, and has various length anodized aluminum stick ends
available (JRPA040-JRPA045). These stick ends are crafted
from bar stock aluminum, and are available at your local JR
dealer.

I-15
Installing the Receiver
Installing the JR R1221
The JR R1221 incorporates a single internal receiver and three
remote receivers offering the security of four simultaneous RF
links for the ultimate in multi-path RF security. One internal
receiver is located on the main PC board, while 2 remote
receivers must be plugged into one of the antenna ports
in order for the system to operate. A third remote receiver
(included) can be plugged into the remaining remote antenna
port giving a total of four operational receivers. By locating
these receivers in different locations throughout the aircraft,
each receiver is exposed to its own RF environment, greatly
improving path diversity (the ability of the receiver to see the
signal in all conditions).
Using double-sided foam tape (servo tape), mount the remote
receiver(s) keeping the remote antenna(s) at least 2” away
from the primary antenna. Ideally the antennas will be oriented
perpendicular to each other; however, we’ve found this to not
be critical. 6”, 9”, 12”, 24”, and 36” leads are available and in
sophisticated aircraft, we’ve found it best to mount the remote
receivers in different parts of the aircraft keeping the remote
antennas as far away as practical from any conductive materials.
A typical installation would include the main receiver mounted
in the conventional location in the fuselage and the remote
antennas in the nose (jets) in the top turtle deck and even in the
tail. The optimum location is as far away from any conductive
materials as practical.
In helicopters, there is generally enough room on the servo tray
to achieve the necessary separation. If necessary a mount can
be made using clear plastic to mount the external antenna.
Other important installation tips:
1. The servos should be mounted using rubber grommets and
brass eyelets to isolate them from vibration. Do not overtighten the mounting screws; this will negate the vibration
absorption effect of the rubber grommets.
Note: The JR R1221 requires that at least two remote
receivers be used.
Install the main receiver using the same method you would use
to install a conventional receiver in your aircraft. Typically wrap
the main receiver in protective foam and fasten it in place using
rubber bands or Velcro straps. Alternately in electric models or
in jets (low vibration), it’s acceptable to use thick double-sided
foam tape to fasten the main receiver in place.
The brass eyelets are pushed from the bottom up in the rubber
grommets. When the servo screw is tightened securely, it
provides the proper security as well as the proper vibration
isolation for your servo.
2. The servo arms must be able to move freely over their entire
range of travel. Make sure that the control linkages do not
bind or impede the movement of any of the servos.
3. Mount all switches away from the engine exhaust and
away from any high vibration areas. Make sure the switch
operates freely and is able to operate over its full travel.
Mounting the remote receiver(s) in a different location(s),
from the primary receiver, gives tremendous improvements
in path diversity. Essentially each receiver sees a different RF
environment and this is the key to maintaining a solid RF link,
even in aircraft that have substantial conductive materials (i.e.
turbine engines with metal tail pipes, carbon fiber, tuned pipes,
etc.) which can attenuate the signal.
I-16
Binding
Binding is necessary to program the receiver to the transmitter
so that the receiver will only recognize that specific transmitter,
ignoring signals from any other sources. If the receiver is not
bound to the transmitter, the system will not operate. During
binding, the servo’s failsafe positions are stored.
The following sequence describes the binding procedure for the
JR1221, however, all JR and Spektrum DSM aircraft receivers
are bound in the same way.
How to Bind
1. With the system hooked up as shown, insert the bind plug
in the charge plug receptacle. The switch must be a 3-wire
type switch (JRPA001 or JRPA004) to enter the bind mode
through the switch. If a 3-wire switch is not available, install
the male bind plug directly into the receiver bind/data
receptacle and power the receiver through any other open
port to enter the bind mode.
3. Establish the desired failsafe stick positions: normally low
throttle and flight controls neutral.

BEFO

US
4. Press and hold the bind button on the back of the transmitter
while turning on the power switch. The bind button should
flash and within a few seconds the system should connect.
The LED’s on the receivers should go solid, indicating the
system has connected.
2. Turn on the receiver switch. Note that the LED’s on all
receivers should be flashing, indicating that the receiver is
ready to bind.
5. Remove the bind plug from the receiver or switch harness
and store it in a convenient place.
6. After you’ve programmed your model, it’s important to
rebind the system so the true low throttle and neutral control
surface positions are programmed.
Note: To bind an aircraft with an electronic speed
controller that powers the receiver through the throttle
channel (BEC), insert the bind plug into the bind/data port
and proceed to Step #2.
I-17
ModelMatch
The 12X features patented ModelMatch technology that
prevents the operation of a model if the wrong model memory
is selected. During binding the receiver actually learns and
remembers the specific model memory (1 through 50) that the
transmitter is currently programmed to. Later, if the incorrect
model memory in the transmitter is selected and the receiver
is turned on, the model simply won’t operate, preventing a
possible crash. Change programming to the correct model
memory and you’re set to fly.
Failsafe Functions
The JR R1221 receiver features two types of failsafe: SmartSafe
and Preset failsafe.
I-18
SmartSafe
This type of fail-safe is especially ideal for most types of electric
aircraft and is also recommended for most types of gas- and
glow-powered airplanes and helicopters. Here’s how SmartSafe
works.
Receiver Power Only
When the JR R1221 receiver only is turned on (no transmitter
signal is present) the throttle has no signal output. This
prevents the arming of the electronic speed control. In glowpowered models, the throttle servo has no input so it remains in
its current position. All other channels are driven to their stored
fail-safe positions.
After Connection
When the transmitter is turned on and after the receiver
connects to the transmitter, normal control of all channels
occurs. After the system makes a connection, if loss of signal
occurs, SmartSafe drives the throttle servo only to its preset
fail-safe position (low throttle) that was set during binding.
All other channels hold their last position. When the signal
is regained, the system immediately (less than 4 ms) regains
control.
Failsafe for JR/Spektrum
Preset fail-safe is ideal for sailplanes and is preferred by some
modelers for their glow- and gas-powered aircraft.
Receiver Power Only
When the JR R1221 receiver only is turned on (no transmitter
signal is present) all channels including the throttle have no
signal output. This prevents the arming of the electronic speed
control. In glow-powered models, the throttle servo has no
input so it remains in its current position. All other channels are
driven to their stored fail-safe positions.
I-19
After Connection
When the transmitter is turned on and after the receiver
connects to the transmitter, normal control of all channels
occurs. After the system makes a connection, if loss of signal
occurs, preset fail-safe drives all servos to their preset fail-safe
positions. For sailplanes it’s recommended that the spoilers/
flaps deploy to de-thermalize the aircraft, preventing a flyaway.
Some modelers using powered planes prefer to use this failsafe
system to program a slight turn and low throttle to prevent
their aircraft from flying away. When the signal is regained, the
system immediately (less than 4 ms) regains control.
Programming SmartSafe
(All JR DSM and Spektrum Aircraft Receivers)
During the binding process, the bind plug is left in throughout
the process and is removed only after the receiver connects
to the transmitter. After the connection is made, confirmed
by operating the servos, the bind plug can be removed. The
receiver is now programmed for SmartSafe.
Programming Preset Failsafe for JR/Spektrum
(JR R1221, JR R1222, JR R921, JR R922, Spektrum AR9000,
and Spektrum AR9100 Receivers Only)
During the binding process, the bind plug is inserted in the
bind port or in the charge jack, and then the receiver is powered
up. The LED’s in each receiver should blink, indicating that the
receiver is in bind mode. Now before binding the receiver to the
transmitter and with the receiver in bind mode, remove the bind
plug. The LED’s will still be blinking. With the control sticks and
switches in the desired fail-safe positions, bind the transmitter
to the receiver by pressing and holding the bind buttons on the
back of the transmitter/module and turning on the transmitter.
The system should connect in less than 15 seconds. The
receiver is now programmed for preset fail-safe.
Note: Fail-safe positions are stored via the stick and
switch positions on the transmitter during binding.
I-20
Range Testing
90 feet (30 paces)
Before each flying session, and especially with a new model,
it’s important to perform a range check. The 12X incorporates
a range testing system which, when the bind button on the
transmitter is pressed and held, reduces the output power,
allowing a range check.
Range Testing
1. With the model resting on the ground, stand 30 paces
(approx. 90 feet) away from the model.
2. Face the model with the transmitter in your normal flying
position and depress and hold the bind button on the back
of the transmitter. This causes reduced power output from
the transmitter.
3. You should have total control of the model with the button
depressed at 30 paces (90 feet).
4. If control issues exist, call the Product Support Department
at 1-877-504-0233 for further assistance.
Advanced Range Testing Using a Flight Log
While the above Standard Range Testing procedure is
recommended for most sport aircraft, for sophisticated aircraft
that contain significant amounts of conductive materials (i.e.
turbine-powered jets, some types of scale aircraft, aircraft with
carbon fuselages, etc.) the following advanced range check
will confirm that all internal and remote receivers are operating
optimally and that the installation (position of the receivers)
is optimized for the specific aircraft. This Advanced Range
Check allows the RF performance of each remote receiver to
be evaluated and to optimize the locations of each individual
remote receiver.
I-21
Advanced Range Testing
Plug a Flight Log (optional, JRPA145) into the data port in the
receiver and turn on the system (Tx and Rx).
Advance the Flight Log until F- frame losses are displayed by
pressing the button on the flight log.
Have a helper hold your aircraft while he observes the Flight
Log data.
Standing 30 paces away from the model and helper, face the
model with the transmitter in your normal flying position and
depress and hold the bind button on the back of the transmitter.
This causes reduced power output from the transmitter.
Have your helper position the model in various orientations
(nose up, nose down, nose toward the Tx, nose away from
the Tx, etc.) while your helper watches the Flight Log noting
any correlation between the aircraft’s orientation and Frame
Losses. Do this for 1 minute. The timer on the transmitter can
be used here. For giant-scale aircraft, it’s recommended that the
airplane be tipped up on its nose and rotated 360 degrees for
one minute then record the data. Next place the airplane on its
wheels and do a second test rotating the aircraft in all directions
for one minute.
After one minute release the bind button. A successful range
check will have less that ten recorded frame losses. Scrolling
the Flight Log through the Antenna fades (A, B, L, R) allows
you to evaluate the performance of each receiver. Antenna
fades should be relatively uniform. If a specific antenna is
experiencing a high degree of fades, then that antenna should
be moved to a different location.
A successful Advanced test will yield the following:
• H- 0 holds
• F- Less than 10 frame losses
A, B, R, L- Frame losses will typically be less than 100.
It’s important to compare the relative frame losses and if a
particular receiver has a significantly higher frame loss value
(2X to 3X) then the test should be redone; if the same results
occur, move the offending receiver to a different location.
I-22
Flight Log—Optional for JR R1221 Receiver
The Flight Log is compatible with JR R1221 receivers. The
Flight Log displays overall RF link performance as well as the
individual internal and external receiver link data. Additionally it
displays receiver voltage.
After a flight and before turning off the receiver or transmitter,
plug the Flight Log into the Data port on the JR R1221
receiver. The screen will automatically display voltage i.e.
(6v2= 6.2 volts ).
Note: When the voltage reaches 4.8 volts or less, the
screen will flash indicating low voltage.
JRPA145
Using the Flight Log
Press the button to display the following information:
• A - Antenna fades on internal antenna A
Holds are indicated when 45 consecutive (one right after the
other) frame losses occur.
• B - Antenna fades on external antenna B
This takes about one second. If a hold occurs during a flight,
it’s important to re-evaluate the system, moving the antennas
to different locations and/or checking to be sure the transmitter
and receivers are all working correctly.
• L - Antenna fades on the left external antenna
• R - Antenna fades on the right external antenna
• F - Frame loss
Note: A servo extension can be used to allow the Flight
Log to more conveniently be plugged in without having to
remove the aircraft’s hatch or canopy. On some models,
the Flight Log can be plugged in, attached and left on
the model using double-sided tape. This is common with
helicopters, mounting the Flight Log conveniently to the
side frame.
• H - Holds
Antenna fades—represents the loss of a bit of information on
that specific antenna.
Typically it’s normal to have as many as 50 to 100 antenna
fades during a flight.
If any single antenna experiences over 500 fades in a single
flight, the antenna should be repositioned in the aircraft to
optimize the RF link.
Frame loss—represents simultaneous antenna fades on all
attached receivers. If the RF link is performing optimally, frame
losses per flight should be less that 20.
I-23
Receiver Power System Requirements
With all radio installations it is vital that the onboard power
system provides adequate power without interruption to the
receiver even when the system is fully loaded (servos at
maximum flight loads). This becomes especially critical with
giant-scale models that utilize multiple high torque/ high
current servos. Inadequate power systems that are unable to
provide the necessary minimum voltage to the receiver during
flight loads have become the number one cause of in-flight
failures. Some of the power system components that affect the
ability to properly deliver adequate power include: the selected
receiver battery pack (number of cells, capacity, cell type, state
of charge), switch harness, battery leads, regulator (if used) and
power bus (if used).
While JR’s receiver’s minimum operational voltage is 3.5
volts, it is highly recommended the system be tested per the
guidelines below to a minimum acceptable voltage of 4.8
volts during ground testing. This will provide head room to
compensate for battery discharging or if the actual flight loads
are greater than the ground test loads.
Recommended Power System Guidelines
1. When setting up large or complex aircraft with multiple high
torque servos, it’s highly recommended that a current and
voltmeter (HAN172) be used. Plug the voltmeter in an open
channel port in the receiver and with the system on, load
the control surfaces (apply pressure with your hand) while
monitoring the voltage at the receiver. The voltage should
remain above 4.8 volts even when all servos are heavily
loaded.
Note: The optional Flight Log has a built-in voltmeter and
it can be used to perform this test.
2. With the current meter inline with the receiver battery lead,
load the control surfaces (apply pressure with your hand)
while monitoring the current. The maximum continuous
recommended current for a single heavy-duty servo/battery
lead is three amps while short duration current spikes
of up to five amps are acceptable. Consequently, if your
system draws more than three amps continuous or five
amps for short durations, a single battery pack with a single
switch harness plugged into the receiver for power will
be inadequate. It will be necessary to use multiple packs
with multiple switches and multiple leads plugged into the
receiver.
3. If using a regulator, it’s important the above tests are done
for an extended period of 5 minutes. When current passes
through a regulator, heat is generated and this heat causes
the regulator to increase resistance, which in turn causes
even more heat to build up (thermal runaway). While a
regulator may provide adequate power for a short duration,
it’s important to test its ability over time as the regulator
may not be able to maintain voltage at significant power
levels over time.
4. For really large aircraft or complex models (for example
35% and larger or jets), multiple battery packs with
multiple switch harnesses are necessary or in many cases
one of the commercially available power boxes/ busses is
recommended. No matter what power systems you choose,
always carry out test #1 above making sure that the receiver
is constantly provided with 4.8 volts or more under all
conditions.
5. The latest generation of Nickel-Metal Hydride batteries
incorporates a new chemistry mandated to be more
environmentally friendly. These batteries when charged with
peak detection fast chargers have tendencies to false peak
(not fully charge) repeatedly. These include all brands of
NiMH batteries. If using NiMH packs, be especially cautious
when charging making absolutely sure that the battery is
fully charged. It is recommended to use a charger that can
display total charge capacity. Note the number of mAh put
into a discharged pack to verify it has been charged to full
capacity.
I-24
Tips On Using 2.4GHz Systems
While your DSM equipped 2.4GHz system is intuitive to
operate, functioning nearly identically to 72MHz systems,
following are a few common questions from customers:
Q: I’ve heard that the DSM system is less tolerant of low
voltage. Is that correct?
Q: Which do I turn on first, the transmitter or the receiver?
A: It doesn’t matter. If the receiver is turned on first, the receiver
starts scanning the band looking for a signal with its pre-bound
GUID. At this time no servo output pulses are present and the
throttle channel doesn’t put out a pulse position, preventing
the arming of electronic speed controllers, or in the case of an
engine-powered aircraft, the throttle servo remains in its current
position. When the transmitter is then turned on, the transmitter
scans the 2.4GHz band and acquires two open channels.
Then the receiver that was previously bound to the transmitter
finds the GUID (Globally Unique Identifier code) stored during
binding. The system then connects and operates normally.
If the transmitter is turned on first, the transmitter scans the 2.4
GHz band and acquires two open channels. When the receiver is
then turned on, the receiver scans the 2.4GHz band looking for
the previously stored GUID; when it locates the specific GUID
code and confirms uncorrupted repeatable packet information,
the system connects and normal operation takes place. Typically
this takes 2 to 6 seconds.
Q: Sometimes the system takes longer to connect and
sometimes it doesn’t connect at all - why?
A: In order for the system to connect (after the receiver is
bound), it must receive a large number of continuous (one after
the other) uninterrupted perfect packets from the transmitter.
This process is purposely critical of the environment, ensuring
that it’s safe to fly when the system does connect. If the
transmitter is too close to the receiver (less that 4 feet) or if
the transmitter is located near metal objects (metal transmitter
case, the bed of a truck, the top of a metal work bench, etc.),
connection can take longer, and in some cases connection will
not occur, as the system is receiving reflected 2.4GHz energy
from itself and is interpreting this as unfriendly noise. Moving
the system away from metal objects or moving the transmitter
away from the receiver and powering the system up again will
cause a connection to occur. This only happens during the
initial connection. Once connected, the system is locked in;
should a loss of signal occur (failsafe), the system connects
immediately (4ms) when the signal is regained.
A: All DSM receivers have an operational voltage range of 3.5
to 10 volts. With most systems this is not a problem as, in fact,
most servos cease to operate at around 3.8 volts. When using
multiple high current draw servos with a single or inadequate
battery/ power source, heavy momentary loads can cause the
voltage to dip below this 3.5 volt threshold, thus causing the
entire system (servos and receiver) to brown out. When the
voltage drops below the low voltage threshold (3.5 volts), the
DSM receiver must reboot (go through the start-up process of
scanning the band and finding the transmitter) and this can take
several seconds. Please read the receiver power requirement
on page I-26 as this explains how to test for and prevent this
occurrence. Note the JR R1221 and newly manufactured JR and
Spektrum DSM receivers have a new QuickConnect feature that,
if a temporary power loss occurs, will reconnect the system in
less than .25 seconds. If a power loss or brownout occurs, the
receiver will indicate the power loss by flashing. If you land and
the receiver is flashing, it’s important that you investigate and
correct the issue that caused the power loss.
Q: Sometimes my receiver loses its bind and won’t connect,
requiring rebinding. What happens if the bind is lost in flight?
A: The receiver will never lose its bind unless it’s instructed to.
It’s important to understand that during the binding process
the receiver not only learns the GUID (code) of the transmitter
but the transmitter learns and stores the type of receiver that
it’s bound to. If the bind button on the transmitter is pressed at
any time and the transmitter is turned on, the transmitter looks
for the binding protocol signal from a receiver. If no signal is
present, the transmitter no longer has the correct information to
connect to a specific receiver and, in essence, the transmitter
has been “unbound” from the receiver. We’ve had several
customers that use transmitter stands or trays that unknowingly
depress the bind button and the system is then turned on,
losing the necessary information to allow the connection to take
place. We’ve also had customers that didn’t fully understand the
range test process and pushed the bind button before turning
on the transmitter, also causing the system to “lose its bind.”
If, when turning on, the system fails to connect, one of the
following has occurred:
I-25
The wrong model has been selected in the model memory
(Model Match).
The transmitter is near conductive material (Tx case, truck bed,
etc.) and the reflected 2.4GHz energy is preventing the system
from connecting (see #2 above).
The bind button was unknowingly (or knowingly) depressed and
the transmitter was turned on previously, causing the transmitter
to no longer recognize the receiver.
Q: Can I use a 3-cell LiPo pack in my transmitter?
A: No. All current JR and Spektrum transmitters are designed
to operate using a 9.6-volt transmitter pack. A fully charged
3-cell LiPo pack puts out 12.6 volts. This higher voltage can
overload the power-regulating transistor, causing damage
and or failure, possibly in flight. Many of our customers have
experienced failures using 3-cell LiPo packs and their use in
JR and Spektrum transmitters is highly advised against. The
12X system will operate for over 8 hours using the included
2000mAh NiMH battery.
6. Q: How important is it that I test my system using a flight
log?
A: For most sport airplanes and helicopters the use of the flight
log is unnecessary. For sophisticated aircraft, especially those
that have significant conductive materials within the airframe
(i.e. jets, scale airplanes, etc.), the Flight Log offers an extra
measure of confidence that all radio components are working
optimally. The Flight Log is an important tool that allows the
confirmation that the installation (position of the internal and
remote receivers relative to the conductive materials in the
aircraft) is optimized and that the RF (radio) link is operating at
the highest levels of performance.

System Mode
Programming a new model generally begins by accessing
the SYSTEM Mode List. System Mode is where models are
selected, the model type is chosen (airplane, helicopter or
sailplane) and other high-level information is programmed
for the model. It is also used to activate some of the more
advanced programming features such as Flight Modes, Switch
Assignments, Wing Types and Dual Control functions.
Accessing the System Mode
1. The System menu [System Mode List] is obtained by
holding down the ENT button while turning the transmitter
on.
84: MODEL SELECT- (Copy Function)
Note: When setting up a new model, it is recommended
that an unused model memory is selected. If a current
model memory is selected, it’s recommended that the
model be reset to the factory default setting before
programming the new model. See model reset page A-9.
Model select allows the programming parameters for up to 50
different models to be stored and selected in up to 50 individual
model memories. This screen also allows a model to be copied
from the current selected model to any of the other 49 available
internal model memories (model copy).

To Select a Model Memory
1. In the SYSTEM MODE, highlight and select Model SEL
using the rolling Selector.
2. Use the rolling Selector to highlight MODEL then press the
roller and select the desired model number to be used.
3. Return to the SYSTEM Menu by pressing the LIST button.
Model Copy
Making a backup copy of the model memory protects against
losing the original program and also allows one to experiment
with the original program, knowing that the original settings
can be restored by copying the backup copy back to the original
model memory.
To Copy a Model to Another Internal Memory
1. In the SYSTEM MODE, highlight and select Model SEL
using the rolling Selector.
5. Press the COPY button to copy the current model list above
to the selected model listed below.
2. Use the rolling Selector to highlight Select then press the
roller to access Model Copy.
6. Return to the SYSTEM Menu by pressing the LIST button.
Note: The model memory that is copied to will be
replaced with the current model memory programming. It
is recommended that a model memory that is not being
used be selected to “copy to,” as the information in that
memory will be erased and replaced with the current
model memory during copying.
3. Rotate the roller to select the desired model memory that
you wish to copy the current program to (1-50).
4. Press the roller to select the highlighted model that you
wish to copy to.

85: Modulation - (12X MV System only)
Note: This function is only available on the 12X MV
version and only when the TSM-72A 72MHz module is
plugged in.
The 12X MV version radio system allows the RF module to be
replaced allowing the system to operate on 72MHz or 2.4GHz.
Note that the transmitter automatically detects which module is
installed and modifies the accessible programming appropriate
to the module selected.
Important: When the 72MHz module is plugged in and
the system is turned on, the antenna must be attached.
Operating the 72MHz module without the antenna attached
could overload the internal transistor causing a failure.
The Modulation screen (code 85) allows the selection of
modulation for 72MHz receiver types. Modulation types
available are:
Warning: Only the JR TSM-72A and JRM2.4 modules
are compatible with the 12X MV. Do not install a standardtype JR, Spektrum or other branded module in the 12X as
damage will occur.
Note: APCM - JR’s newest version PCM (not available in
the U.S.)
• SPCM - Most currently available JR PCM receivers use this
type of modulation
• ZPCM - Compatible with older JR receivers
• PPM - FM modulation
Note: It’s important to select the modulation to match
the receiver type. JR receivers have the modulation type
printed on the receiver.

93: Frequency Select- (12X MV system only)
Note: This function is only available on the 12X MV
version and only when the TSM-72A 72MHz module is
plugged in.
The 12X MV version radio system allows the RF module to be
replaced allowing the system to operate on 72MHz or 2.4GHz.
Note that the transmitter automatically detects which module is
installed and modifies the accessible programming appropriate
to the module selected.
Important: When the 72MHz module is plugged in and
the system is turned on, the antenna must be attached.
Operating the 72MHz module without the antenna attached
could overload the internal transistor causing a failure.
The Frequency Select function allows the selection of 72MHz
channels 11 through 60 when the 72MHz module is installed.
This screen displays the channel and corresponding frequency.
Warning: Only the JR TSM-72A and JRM2.4 modules
are compatible with the 12X MV. Do not install a standard

left side of the screen. To transmit press RF-ON.
A-12
83: Trim System
The Trim System function adjusts the sensitivity of the 12X trim
levers and the Flap and Aux trimmers (right and left trimmers).
The standard digital trims are adjustable from 0–10 with 10
being the coarsest adjustment and 0 being trim off. Adjusting
the digital trim values has no effect on the total trim travel,
however, it affects the resolution of each trim input. When the
value is set to 10, each click of trim adjusts the servo output by
10ms and there are only 10 trim increments from center to each
end. When set to 5, the output is changed 5ms per trim step
and there are 20 trim increments from center to each end. When
set to 1, each click of trim changes the servo output by 1ms
and there are 100 trim increments. When set to 0 the trim levers
cease to function effectively, turning off the trim function. The
right and left trim levers are adjustable from 0 to 200 and can
be turned on/ off. When adjusted to above 100% the trimmer
functions as a two- or three-position switch. Reducing the value
increases the number of output positions.
When adjusting the digital trims (AILE, ELEV, RUDD), the total
trim travel does not change – only the number of increments
(beeps) changes, which makes for finer or coarser trim
movements. When adjusting the analog throttle trim, however,
the total trim travel is actually reduced when set to less than
100%.
Use a fairly coarse setting, such as the factory default 4, when
test flying a model for the first flights in order to be able to
trim it quickly; then use a finer setting, such as 3–1, for final
precision trimming.
L.S.T. Trim (Limited Standard Trim)
The L.S.T. trim feature has two options: L.S.T. and normal. In
normal, when making trim changes using the aileron, elevator
or rudder digital trims, the center as well as the end points is
affected by the trim values. The right trim causes the center,
the right end point and the left end point to all shift to the
right. When L.S.T. is activated, only the center position is
trimmed. The center is shifted to the right but the endpoints
are not affected. This is useful for aircraft that have a hard stop
endpoint to prevent over-travel caused by trim or if it’s desired
to have trim changes not affect the total roll pitch or yaw rate.
A-13
To Adjust the Trim Rates:
1. Highlight and select TRIM SYS. in the SYSTEM MODE to
acquire the Trim System function.
2. Highlight and select the trim that is to be changed and
use the Selector to set a value of 1–10 (1 = finest, 10 =
coarsest).
Note: The Flap and AUX trims are adjustable from 0 to
200 and can be turned off or on by selecting On or Off.
3. Repeat for other trims as desired.
To Select the L.S.T. Trim Function
1. Highlight and select the desired channel (AILE, ELEV or
RUDD) next to (TYPE) L.S.T. and press the roller to select
L.S.T. or NORM
2. Repeat for other channels as desired
A-14
91: Stick Position Switch
The Stick Position Switch function allows the throttle, aileron
elevator or rudder stick positions to be preprogrammed to turn
on/ off mixes, change throttle curves, change differential rates,
start a timer and other functions. An example of this would be
to have a smoke system that turns off below 25% throttle to
prevent low throttle flameouts. Four stick position programs are
available and one or more can be assigned to various mixes or
functions. The stick position that turns the Stick Position switch
off /on is selectable as well as the direction to turn on/ off. Also
a symmetrical option is available that allows the function to
be turned on with a preprogrammed equal right or left (up or
down) stick position.
To Program a Stick Position Switch
1. In the SYSTEM MODE, highlight and select STK PosSW
using the Selector.
2. Highlight the desired Stick position switch that you desire
to use (SPS0, SPS1, SPS2, or SPS3) and press the roller.
All four are the same.
3. Select the desired channel that will be used to trigger the
Stick position (Throttle, Aileron, Elevator, and Rudder).
6. A symmetrical function is available that allows the stick
position to be turned on/ off as the stick is displaced
symmetrically in either direction. It’s necessary to first
program a value in the POS, then highlight the SYM
and activate it using the roller. The center can now be
programmed to turn on or off by selecting the ON and
highlighting Low/ High or Right /Left.
Note: The above procedure establishes the base for
turning on/ off mixes, change throttle curves, changes
differential rates, etc. To program the stick position, it’s
necessary to go to the desired function in Function mode
and select SPS0, SPS1, SPS2 or SPS3 under SW (switch)
in that specific function.
4. Rotate the roller to select POS and adjust to the desired
value that you wish to have the mix function turn off/ on.
0 = center, L100= Left full stick travel, etc. Note ON/ OFF
is displayed at the top of the screen and when moving the
stick this will indicate that the function is working.
5. Use the roller to select ON and select Low/ High or Right /
Left to access the desired direction that the function will
turn on/ off.
7. Return to the SYSTEM Menu by pressing the LIST button.
A-15
92: Flight Mode Name

Return to the SYSTEM Menu by pressing the LIST button.
86: Transfer
Note: The sending and receiving transmitters must
both be 12X’s or the PC Data Transfer device and a 12X.
Transfer is not possible with any other system.
The TRANSFER function allows one 12X transmitter to transfer a
model memory for a specific model to another 12X transmitter.
This function is also used to transfer a model memory to the
included PC Data Transfer allowing unlimited model memory
storage and backup of your model’s programming. The Transfer
function is also used to receive data from another 12X or from
the PC Data Transfer.
Preparing the 12X to Receive a Model Transfer
Note: The receiving model name/memory number can
not be the currently selected model. If you wish to receive
a model in the currently selected model name/memory
number, go to the model select function and select a
different model, then reenter the transfer function and
follow the instructions above.
1. Hold the ENT button while plugging the Trainer cord into
the back of the transmitter to obtain the SYSTEM List. Plug
the other end of the DSC cord into another 12X transmitter
while holding the ENT button and after the following,

above.
2. Highlight and select TRANSFER in the SYSTEM Menu to
obtain the Transfer display.
3. If RECEIVE is already displayed, continue with the next step.
If TRANSMIT is displayed, highlight and select TRANSMIT,
changing it to RECEIVE.
5. Press START on the left side of the display. Stand-by
appears at the bottom of the display indicating that the
system is ready to receive data. Follow the next steps to
prepare the sending transmitter for memory transfer.
4. Select the model memory that is to receive the data by
highlighting and selecting the model name/memory number
and then scrolling to and selecting the model memory that
is to receive the data. Select an unused model memory or
a memory that contains data for a model that is no longer
needed as the data in this model memory will be replaced
by the model memory that is transferred and will be
permanently lost.
A-17
Preparing the 12X to Send a Model Transfer
1. With the other end of the trainer cord plugged into the
sending 12X transmitter in SYSTEM List as described in
step 1 above, highlight and select TRANSFER (code 86) in
the SYSTEM Menu to obtain the Transfer display.
2. The model to be transferred must be the currently selected
model. If the model to be transferred is not currently
selected, see Model SEL in the SYSTEM Menu to select the
model to be transferred.
3. When the receiving 12X is ready, press START on the left
side of the display. The data for the currently selected model
is transferred to the receiving device.
A-18
97: Warning
The Warning function can be programmed to sound an alarm if
a selected flight mode, switch positions or throttle stick position
is in an inappropriate position when the transmitter is turned
on. For example if the gear switch is in the retraced position
and the transmitter is turned on, an alarm can sound warning
that the switch will cause the gear to retract if the receiver is
turned on. Or if the throttle is above a preprogrammed position
when the transmitter is turned on an alarm will sound warning
of an unsafe throttle position for startup. Stick positions can
also be programmed to sound alarms. See page A-15 for
programming stick position switches. Note that during the
warning no signal is being transmitted. The Throttle stick is
defaulted with a warning above 10% and an alarm will sound
and no signal will be transmitted if the throttle is above 10%
and when the transmitter is turned on. The warning function is
available for the following:
• Flight Mode 0
• Flight Mode 1
• Flight Mode 2
• Flight Mode 3
• Flight Mode 4
• Flap Switch Normal
• Flap Switch Mid
• Flap Switch Land

A-20
17: Device Select
Device Select is used to activate some of the more advanced
features of the 12X. The Device SEL function is used to activate/
inhibit the following:
• Flight Modes (5 in total)
• Throttle Hold
• Flap Trim
• Trim Common
• Switch, Lever and Knob Assignments
• Activate/Inhibit Switches/Channels
• Activate/Inhibit the Governor
• Activate/Inhibit the Gyro
• Activate/Inhibit the Pitch Curve Function
• Activate/Inhibit the Flap System
• Assign Functions and Channel to the Desired
Switch Knob or Lever
Each of these options is described as follows.
Flight Modes
A Flight Mode represents an aircraft configuration (Dual Rate/
Expo, program mixes, Aileron Differential, Flap System, Gyro
System, etc.) that is programmed to optimize the control system
to assist the pilot and the aircraft in performing a specific type
of maneuver. Up to 5 flight modes are available in the 12X.
The objective of programming Flight Modes is to provide the
ability to select a switch position to activate a collection of
settings that are optimized to perform a maneuver. An aerobatic
aircraft, for example, may be set up such that the Flight Mode
switch in its 1st position (FM 0) configures the aircraft for
precision flying; positioning the switch in its 2nd position (FM
1) sets the aircraft up for snap rolls; and positioning the switch
in its 3rd position (FM 2) sets the aircraft up for aggressive
3D flight. Flight Modes could just as easily represent aircraft
settings for Take Off, Flying, and Landing for a turbine-powered
jet aircraft. Flight Modes can make the pilot’s job easier by
configuring and optimizing the aircraft to do different things by
flipping a single switch.
Most of the functions found in the 12X that are switch
selectable including programmable mixers, throttle curves,
differential, gyro settings, servo speed, etc. can be assigned
to one or more Flight Modes. This provides the ability to have
up to 5 completely different aircraft configurations that are
selectable in flight using switches.
Five Flight Modes are available in the 12X system. When 3
Flight Modes are activated, they are selected during flight by
using one of six 3-position switches (Flight mode switch,
Rudder D/R switch, Flap switch, Elevator D/R switch, Aux 2
switch, Aileron D/R switch, or Inhibit). To activate the 2 Extra
flight modes (5 flight modes in total) the 4th and 5th flight
modes are assigned to one of the following switches (Mix
switch, Elevator D/R switch, Gear switch, Aileron D/R switch,
one of the stick position settings (SPO0-SPO3), or Inhibit).
Flight mode switches are selected and activated in the Device
SEL function in the System menu. Once Flight Modes are
activated, the pilot has a choice of using the Flight Mode switch
to select up to 5 Dual Rates and Exponential settings for each
of the primary controls (ELEV, AILE, RUDD), or Dual Rates
and Exponential settings may continue to be controlled by the
3 individual Dual Rate switches. All other functions that can
be activated by a switch can be assigned to 1 or more Flight
Modes when Flight Modes have been activated.
A-21
To Activate Flight Modes
1. From SYSTEM Mode List, highlight and select DeviceSEL
using the Selector.
2. Using the Selector, highlight and select INH next to FLIGHT
MODE. When selected, 7 options appear: (Flight Mode
SW, Rudder D/R SW, Flap SW, Elevator D/R SW, Aux 2 SW,
Aileron D/R SW, or INH) Highlight and select the desired
flight mode switch.
Once Flight Modes have been activated, FLAP TRIM and TRIM
appears on the display.
3. To activate the two extra flight modes, using the Selector,
highlight and select INH next to EXTRA. When selected,
8 options appear: MIX SW, Elevator D/R SW, GEAR SW,
Aileron D/R SW, SPO0, SPO1, SPO2, SPO3, or INH)
Highlight and select the desired EXTRA flight mode switch
to activate the additional two flight modes.
A-22
Throttle Hold
Note: Throttle hold is defaulted to the mix switch.
The throttle hold function is normally used as a kill switch
for glow-powered airplanes or as a safety/ arming switch
for electric-powered aircraft. It can also be used to preset
a programmed throttle position. For example with electric
sailplanes it can be used to give full power when the switch
is activated. The throttle hold function switch position and
direction is assigned in Device Select. The actual programming
of the throttle hold position is done in Code 16 Throttle Hold
screen in the Function mode (see page A-33).
To Assign Throttle Hold to a Switch
1. In Device Select, highlight and select Throttle Hold using
the Roller.
2. Using the Selector, highlight and select MIX SW next
to THRO Hold. When selected, 12 switch options and
directions appear: Highlight and select the desired throttle
hold switch and direction.
A-23
Flap Trim
1. The digital FLAP TRIM lever is located on the front right
face of the transmitter and is accessed with your right
index finger. Flap Trim may be activated or deactivated in
the Devic.SEL function by using the Selector to highlight
either ON or OFF and pressing the Selector. The flap trim is
defaulted to ON.
Ordinarily this switch should be turned OFF, even if the aircraft
has flaps or dual ailerons, The 12X provides other means of
controlling flaps and disabling this switch will help prevent an
out-of-trim condition if flaperons are used and the trim lever is
accidentally moved.
A-24
Trim
The Trim function can be toggled between COM (common)
and F.M. (Flight Mode) by pressing the Selector when COM
or F.M. is highlighted. In the COM mode, the digital trims for
Elevator, Ailerons, and Rudder are common or shared in all
Flight Modes. If a trim change is made in any flight mode, the
trim in all flight modes are also changed (common trims in all
flight modes). If F.M. is selected in Stunt Trim, the 12X stores
the digital trim positions independently for each Flight Mode.
This allows the aircraft to be independently trimmed in each
flight mode and when that flight mode is selected the previously
set trim value for that flight mode is active. This is a very useful
feature if switching between Flight Modes causes the aircraft’s
trim to change, such as when flaps are deployed by one of the
Flight Modes causing the aircraft to have a pitch change. In this
case, the pilot can simply use the Elevator digital trim to trim
the Elevator to correct the pitch up tendencies when the flaps
are deployed using a flight mode. Selecting each Flight Mode
brings in a corresponding set of trims, allowing the aircraft to
be independently trimmed for each flight mode during flight.
Note: When Trim is set to FMOD, be aware during the
first flight and remember that the aircraft will need to be
trimmed using the digital trims for Aileron, Elevator and
Rudder for each Flight Mode selected during flight. If the
aircraft is badly out of trim, remember that when switching
from flight modes each flight mode will require trimming.
A-25
Switch Assignments
The 12X provides the ability to change the standard default
switch assignments for the GEAR, FLAP, AUX2, AUX3, AUX4,
AUX5, AUX6, and AUX7 channels. Changing the switch
assignments is a matter of preference. The standard switch
assignments may be changed in the Devic.SEL function
contained in the SYSTEM MODE.
To Change One or More Switch Assignments:
1. In the Devic.SEL function, use the Selector to highlight
and select the desired channel to the right of GEAR, FLAP,
AUX2, AUX3, AUX4, AUX5, AUX6 or AUX7.
2. Once a switch is selected, a list of available switches is
graphically displayed. Highlight and select the desired
switch with the Selector.
3. Repeat for as many switches as desired.
Activate/Inhibit Channels
Note: When SYS appears next to FLAP, the FLAP SYSTEM
function will appear in the FUNC.LIST (described later).
If the aircraft is equipped with flaps, or equipped with
Flaperons that are actually going to be used as flaps then
SYS should be set next to FLAP.
The 12X provides the ability to activate, inhibit or program
channel 5 (Gear), channel 7 (Aux2) and channel 8 (AUX 3) to
operate as a Governor, Gyro or Pitch function.
Note: Inhibiting a channel is necessary when auxiliary
channels are used as dual primary flight controls, such
as using 2 channels/servos for 2 Ailerons or 2 servos/
channels to operate the Elevator or Rudder. In this
instance, the auxiliary channels are no longer to be
operated by their auxiliary switches but rather by the
Elevator and Rudder sticks and must be inhibited in the
Device Select function.
Note: When GYR appears, the Gyro Function will appear
in the FUNC.LIST (described later on page A-38). Two
gyro programs are available.
Note: When GOV appears, the Governor Function will
appear in the FUNC.LIST (described later on page A-38).
Flight modes must be active for this function to be
available.
Note: If any of the channels identified above are to be
used as a 2nd channel for a primary flight control (AILE,
ELEV, RUDD, FLAP), then be sure to Inhibit (INH) the
switches for the channels in this function or they will not
be available to use as a second control channel.
Note: When PIT appears, the Pitch Function will appear in
the FUNC.LIST (described later on page A-55).
1. If GEAR, FLAP, AUX2, AUX3, AUX4, AUX5, AUX6 or AUX7
are to be used as a 2nd primary flight control, then inhibit
the corresponding switch by highlighting ACT along the
right side of the display; press the roller to select INH.
A-26
22: Wing Type
Wing Types
The Wing Type function provides for 4 different wing types
(NORMAL, FLAPERON, DELTA and 4- Aileron).
NORMAL wing type is used when only the Aileron channel is
to be used to control ailerons, either with 1 servo, or multiple
servos connected through a Y-harness to the aileron channel.
FLAPERON is typically used when each Aileron is controlled by
a separate servo that is on separate channels and there are no
other flaps on the aircraft. Setting the wing type to FLAPERON
also makes available the Aileron Differential and Elevator-toFlap mixing functions in the FUNC.LIST (described later).
DELTA is used with Delta wing aircraft (also referred to as
Elevon). With Delta wing type the Ailerons and elevator are
mixed giving roll and pitch control for Delta wing airplanes.
4-AILERON is used in aircraft where two servos are used to
operate the right aileron and two servos are used to operate the
left aileron. In this configuration each servo is independently
adjustable for sub trim and travel adjust. A balance function is
also available (page A-38) that allows the servo output to be
matched throughout its travel preventing binding due to linkage
geometry inaccuracies.
V-Tail Mix
V-Tail The Wing Type function provides programming for
aircraft that have a V-Tail configuration where the 2 tail control
surfaces are used for both Elevator and Rudder control.
Dual Flight Controls
Dual Control Functions
Wing Type allows Dual Aileron, Dual Elevator, Dual Rudder
and Dual Flap functions to be activated. This function is
used when two servos are used to drive the primary control
surfaces allowing the independent adjustment of for sub
trim and travel adjust of each channel. A balance function is
also available (page A-38) that allows the servo output to be
matched throughout its travel preventing binding due to linkage
geometry inaccuracies.
Note: To access Dual Flaps it is necessary to assign the
Flap to SYS (system) in Device Select. When Dual Flaps
are activated, Aileron-to-Flap mixing becomes available in
the function list (page A-54).
Note: Dual ailerons is a very important commonly used
function because a large number of sport and aerobatic
aircraft use 2 servos and 2 channels to operate the
Ailerons, providing the ability to utilize Aileron Differential
and to allow precise independent adjustment of sub trim
and travel adjust for each aileron.
If the aircraft has flaps that are separate from the Ailerons,
the Dual aileron wing type and (activating dual flaps) is
recommended.
Twin Engine Control
The Wing Type function contains the Twin Engine (Twin E.)
feature, which allows for setting up a 2nd throttle channel for
a second engine, complete with its own independent sub trim,
travel adjust and separate trims and throttle curves.
A-27
Wing Type
To Program a Wing Type
Note: If the ailerons are not going to actually be used
as flaps, inhibit the FLAP Switch and FLAP TRIM in
the Devic.SEL function in the SYSTEM Menu. This will
eliminate having a severe out-of-trim condition if the FLAP
Switch or FLAP TRIM is accidentally moved.
1. Highlight and select Wing Type in the System Mode List
using the roller.
2. Use the roller to highlight Wing then select the wing type
that is appropriate for your aircraft.
Normal- If the Aileron channel only is used to control both
ailerons, either with a single servo or with 2 servos connected
together via a “Y” harness, then the NORMAL wing type should
be selected. Also use NORMAL if the aircraft has flaps that are
separate from the ailerons; if two aileron channels are used,
activate the Dual aileron channel listed below.
Flaperon- If 2 channels are to be used to control the Ailerons
and the aircraft does not have separate flaps, select FLAPERON
as the wing type. Plug the right Aileron into the Aileron channel
(Ch2) and plug the left Aileron servo into the FLAP or AUX1
channel (Ch6) of the receiver
DELTA- If you have a Delta wing aircraft then select DELTA in
wing type. This will mix the aileron and elevator functions to
provide roll and pitch control for these types of aircraft. Plug the
right control surface into the aileron channel (CH2) and plug
the right surface into the elevator channel (CH3).
4-Aileron- If your airplane is equipped with two servos for the
right aileron and two servos for the left aileron, then select the
4- Aileron option. Right aileron servos plug into channel 2 and
channel 7. Left aileron servos plug into channel 5 and channel
8. Each servo is independently adjustable for sub trim and
travel adjustment and the digital trim is active for all servos.
A-28
V-Tail
1. If the aircraft has a V-tail configuration, highlight INH next
to V-tail in the Wing TYPE function and press the roller
until ACT appears. Plug the right Elevator servo into the
Elevator channel (Ch3) and plug the left Elevator servo into
the Rudder channel (Ch4).
Dual Channels
1. To assign a 2nd channel to Ailerons, Elevator, Rudder or
Flaps, highlight and select INH under the desired channel
on the Mate line of the Wing TYPE display and a list of
available channels is displayed.
Note: Channels/Switches must be inhibited (INH) in the
Devic.SEL function before they will appear in the list as an
option to be used as a Dual channel. The Flap SYS must
be selected in the Deivc.SEL screen to access the Dual
Flap function.
2. Highlight and select the channel that is to be the Mate
(slave) to the control channel represented above it. Plug the
2nd control surface servo into the channel selected as the
Mate.
3. INH will appear on the Trim Line of the display directly
beneath the channel just selected. This means that the
corresponding digital trim (FLAP TRIM or AUX TRIM)
located next to the FLAP and AUX2 switches can be used
as additional trims. However, the additional trims do not
function in the same fashion as regular trims. Instead,
they trim the controls such that both channels move in the
same direction – like reflexing both Ailerons or in the case
of Elevator halves, the Elevators would move in opposite
directions. As a result, these additional trims should remain
inhibited unless there is a special need for them. If changed
to ACT, the corresponding trim switch (Right Trimmer
or Left trimmer) will become active. If set to INH these
additional trim switches are inactive. Normal trims continue
to work regardless of the settings.
A-29
Twin Engine
If the aircraft is equipped with twin engines, the Twin Engine
feature (Twin E.) may be used for a 2nd throttle channel with an
optional separate digital trim.
1. Highlight and select INH next to Mate under Twin ENGIN.
A list of available channels will appear. Select the desired
channel to be used as the second throttle channel. Plug the
Left engine throttle servo into the channel selected as the
Mate. Plug the Right engine throttle servo into the throttle
channel (Ch 1).
2. If the second throttle channel is to be trimmed using either
the normal throttle trim lever or a separate trim lever,
highlight and select INH next to Trim under Twin E. causing
the setting to change to ACT. When set to ACT, the 2nd
throttle servo can be trimmed with the normal throttle trim.
Function Mode
The Function Mode contains programming that is used to
complete the setup and then to adjust the aircraft’s flight
characteristics. Functions include Servo Reversing, Travel
Adjust, Dual Rate and Expo, Sub Trim, Servo Speed,
Programmable Mixes, Trainer and Timer functions, etc. Many
of these functions are frequently used to adjust the flight
characteristics during setup and at the field.
To Enter the Function Mode List
With the transmitter on Press LIST and the Function list will
appear.
A-30
11: Servo Reversing
The servo reverse screen allows the direction of each servo to
be selected.
To Program Servo Reverse
1. Highlight and select REV.SW in the FUNC.LIST to obtain the
servo reversing display.
2. Use the Selector to highlight and select those channels
that need to be reversed. Pressing the Selector toggles the
channel between Normal and Reverse.
12: Travel Adjust
Travel Adjust allows the independent adjustment of servo travel
for each direction of servo travel.
To Program Travel Adjust Values
1. Highlight and select TRVL ADJ. in the FUNC.LIST to obtain
the Travel Adjust display.
2. Use the Selector to highlight and select each channel and
adjust the travel in each direction by rotating the Selector.
The direction of travel is changed by moving the stick/
switch/lever in the desired direction to highlight L/R, U/D
or +/-.
A-31
13: Dual Rate and Exponential
Note: If extra flight modes are activated, up to 5 dual and
exponential rates are available. Dual and Expo rates are
independently adjustable in each direction by moving the
appropriate stick in the desired direction.
Three dual and exponential rates are available and are selectable
via flight modes or selected switches.
To Program Dual Rate and Exponential Values
1. Highlight and select D/R & EXP in the FUNC.LIST to obtain
the Dual Rate and Exponential display.
2. Highlight and select the desired channel (Aileron, Elevator
or Rudder), noting that 3 sets of values will be displayed for
each channel – Aileron, Elevator and Rudder.
3. Use the Roller to select and change the desired D/R
and Expo values. Note that D/R and Expo values can be
independently adjusted by holding the corresponding
control stick in the desired direction while making
adjustments.
Assigning Dual and Expo Rates to Flight Modes
Note: The Dual and Exponential rates can be combined
and assigned to each of up to 5 flight modes. Flight modes
must be activated in Device Select (see page A-21) to
access the Auto D/R and Expo function allowing dual rates
to be automatically selected in each flight mode.
To Assign D/R and Expo Values to Flight Modes
1. Highlight and select D/R & EXP in the FUNC.LIST to obtain
the Dual Rate and Exponential display.
2. Flight Modes must be activated in Device. Use the roller to
select AUTO and activate the auto function.
3. Highlight and select the desired channel (Aileron, Elevator
or Rudder), noting that 3 sets of values will be displayed
if three flight modes are active and 5 sets of values will be
displayed if 5 flight modes are active for each channel.
4. Use the Roller to select and change the desired D/R
and expo values. Note that D/R and Expo values can be
independently adjusted by holding the corresponding
control stick in the desired direction while making
adjustments.
A-32
15: Sub Trim
Use Sub Trims to fine-tune the output alignment of the servo
arms.
To Program Sub Trim Values
2. Highlight and select the channels where the sub trims must
be adjusted. Once a channel is selected, rotate the Selector
until the servo arm is in the desired position.
1. Highlight and select Sub Trim in the FUNC.LIST to obtain
the Sub Trim Display.
16: Throttle Hold
The throttle hold function is normally used as a kill switch
for glow-powered airplanes or as a safety/ arming switch
for electric-powered aircraft. It can also be used to preset a
programmed throttle position for electric sailplanes to give full
power when the switch is activated. The throttle hold function
switch position and direction is assigned in Device Select. The
programming of the throttle hold switch position is done in
Device Select screen in the System mode (see page A-21).
Note: Throttle hold is defaulted to the mix switch.
To Activate Throttle Hold:
1. Highlight and select THRO Hold in the FUNC.LIST to obtain
the Throttle Hold Display.
2. Highlight IHN and press the roller to activate the Throttle
Hold function.
3. Highlight the HOLD Pos. and press the roller to allow
throttle hold positions to be adjusted. 0% = low throttle low
trim. 100% =full throttle.
Note: The currently selected Throttle Hold switch is
displayed under ACT. MIX SW is the default setting. To
select another switch see Device Select Throttle Hold on
page A-21.
A-33
18: Throttle Curves
Programmable throttle curves allow the throttle response (stick
position vs. throttle output) to be manipulated. This is useful to
optimize the throttle response for various maneuvers like torque
rolls. Programmable throttle curves can be adjusted with the
THRO CURV function. Two programmable throttle curves are
available.
If the Twin E. function has been activated in Wing Type (page
A-27 for twin-engine aircraft, independent throttle curves are
available for each engine to help eliminate discrepancies in rpm
between the two engines at all throttle positions.
To Program a Throttle Curve
1. Highlight and select THRO CURV in the FUNC.LIST. and
press YES or NO to access the throttle curve function. Two
different throttle curves can be programmed referenced to
as Pos0 and Pos1.
2. If there is a need to have 2 throttle curves, use the Selector
to highlight SW SELECT and a list of available Flight
Modes and switches appears. Select the Flight Mode(s)
(FM0, FM1, or FM2), switches and/or switch position
(SPS) that is desired to be used to select between the 2
curves. The switch will be used to select between the Pos0
curve and the Pos1 curve. Highlight and select Pos0 to
toggle between the Pos0 and Pos1, in order to display and
adjust the 2 curves.
Note: If Twin E. has been activated for a twin engine
aircraft, there will be a Pos0 and Pos1 for both the right
and left engines, providing a total of 4 possible throttle
curves. However, instead of being named Pos0 & Pos1,
they are named RTH.0, RTH.1, LTH.0, and LTH.1. They
represent Right Throttle Pos0 & Pos1 and Left Throttle
Pos0 & Pos1 respectively.
3. Highlight EXP and select it to turn exponential ON if
desired. This will result in a smoothed throttle curve.
4. Using the roller, highlight the desired point (L, 1, or H) and
press the roller to access the output value. Rotate the roller
to change the output value. Repeat for all desired points.
Note the graphic display will change to represent the new
point position.
5. To adjust access Pos1 throttle curve (only available when
SW is assigned to a switch) highlight Pos0 and rotate the
roller to access Pos1 and repeat the step above to adjust
Pos1 throttle curve.
6. To adjust the throttle trim authority, highlight the TRIM
using the roller and rotate to select a trim authority value of
0 100%. Note the graphic display will change to represent
the new trim authority.
7. To store a new point move the throttle stick until store
appears on the lower left side of the screen. When the
desired position is achieved press the store button and the
point will be stored onscreen. Up to eight points can be
stored.
9. THRO STK allows the throttle stick to be used to switch
from Pos0 throttle curve to Pos1 throttle curve. To program
a throttle curve Pos change with the throttle stick highlight
the THRO STK and adjust the values using the roller to
program the point at which the throttle curve is selected
between Pos0 and Pos1.
A-34
24: Servo Speed
The 12X provides the ability to adjust the speed of servos on
each channel in each direction. The speed may be reduced
(servo slowed) from its normal speed but it cannot cause a
servo to move faster than its rated specifications. Each servo
can have 2 sets of speeds in each direction that are Flight Mode
or switch selectable.
The servo speed function can be very useful for scale models
with retractable landing gear and gear doors, since in many
instances the need for gear door sequencers can be eliminated.
If the gear door servos move at normal speed and the landing
gear servos move at a slower speed when the gear is lowered,
the gear doors will be open before the landing gear begins to
come down. In the opposite direction, if the gear door servos
move slowly and the landing gear servos move at normal
speed, the gear can retract before the gear doors begin to close.
Note: Many retract servos are non-proportional type
servos that simply move from end point to end point.
These types of servos are not adjustable in the servo
speed function.
To Adjust Servo Speed
1. Highlight and select SRV. Speed. Speed FUNC.LIST.
2. Select SW SEL and press the roller to access Switch Select.
If only one servo speed is desired, then all selectable switch
positions in this screen should be P0. If two servo speeds
are desired, then assign the desired switch that will change
the servo speed to P1. Return to the main screen.
3. If a single set of servo speeds is desired, make sure the
display is showing Pos0. If it is not, select Pos1 and
change it to Pos0. Highlight and select the channel and
direction for each servo that is to be adjusted. Once a
direction for a servo is selected, the servo speed may be set
so the servo travels from .193 seconds for 60 degrees of
rotation to 16.4 seconds for 60 degrees of rotation. Adjust
the speed of each servo until the desired speed is obtained.
4. If 2 sets of servo speeds are desired that are Flight Mode
or switch selectable, one set of values is set to NORM for
all channels, and the slowing of servos can be turned off by
selecting the position (Pos0 or Pos1) that has the NORM
values. Highlight and select Pos0 and change it to Pos1
and then highlight and select the channel and direction for
each servo that is to be adjusted. Once a direction for a
servo is selected, the servo speed may be set so the servo
travels at the desired slower rate. Switch between Pos0 and
Pos1 to view and adjust the 2 sets of values for each servo.
A-35
Note: Pos1 always has priority over Pos0. In other words,
if multiple switches are selected and one of the switches
is in its Pos1 position, then all other switches are ignored
and the Pos1 values are in effect.
31: Snap Roll
The 12X has a Snap Roll system that can combine the Snap
Roll switch with Flight Modes to select a direction (Right/
Up, Right/Down, Left/Up, and Left/Down) and the amount of
deflection for Aileron, Elevator and Rudder. Up to four directions
and corresponding rates can be programmed and a Direction/
Rate combination can be assigned to 1 or more of the 5 Flight
Modes. Pressing the Snap Roll switch causes the aircraft to
snap roll in the direction according to the rates assigned to the
Flight Mode that is currently selected.
A Snap Roll stick switch position (Stick SW) can be
programmed that will cause the respective control surface to
skew to the programmed snap roll position when the stick is
displaced beyond the programmed position.
Important: Use this function with extreme caution.
If Flight Modes have been activated, up to 5 Snap Roll
directions/rates can be assigned —one per Flight Mode. If
Flight Modes have not been activated then only one directions/
rate is available. The Snap Roll function is inhibited as a default
and must be turned on in order to use it.
If the Snap Roll Function Is To Be Used
1. Highlight and select Snap Roll in the FUNC.LIST and then
select INH to activate a single snap roll or select S.ROLLØ
to activate up to 5 snap rolls assigned to Flight modes.
2. Scroll to the desired channel and set it to a desired value.
3. Repeat step 2 for the other channel’s directions.
4. If more than one snap direction/ value is desired Highlight
S.ROLLØ to access the snap roll 0 thru 4 and repeat the
above steps for each snap roll.
A-36
32: Differential
The 12X Aileron Differential function reduces the travel of the
Aileron that deflects downward without affecting the Aileron
that travels upward and, therefore, can eliminate adverse yaw
tendencies in rolling maneuvers.
The Aileron Differential function provides for 2 differential
settings that are switch or Flight Mode selectable – Pos0 and
Pos1.
Note: Differential is available in the FUNC.LIST only if
the FLAPERON, Delta or 4-Aileron is selected in the Wing
Type function in the SYSTEM Menu or a Dual channel has
been assigned to ailerons in the Wing TYPE function.
To Use the Aileron Differential Function
1. Highlight and select AIL Diff. in the FUNC.LIST to obtain
the Aileron Differential display.
2. If there is to be a single Aileron differential setting that is
on all of the time, highlight and select Pos0 and adjust
the desired percentage of differential. A positive value
causes the downward Aileron to travel less while a negative
value causes the upward Aileron to travel less (negative
differential).
3. If two differential values are needed, highlight SW SEL and
press the roller to select the desired switch(s) to select
between Pos0 and Pos1 differential settings.
4. Return to the Differential screen and make adjustment to the
POS 1 differential as desired.
Note: Pos1 always has priority over Pos0. In other words,
if multiple switches are selected and one of the switches
is in its Pos1 position, then all other switches are ignored
and the Pos1 values are in effect.
A-37
33: Balance
The 12X features a Balance function that allows the servo
outputs of dual channels to be adjusted throughout the range.
This is useful when two servos are used to drive a single
surface (i.e. two aileron servos used to drive one aileron) and
the linkage geometry of each servo is slightly different (typical
with a tapered aileron). If both servos are mixed in a linear
fashion, binding will occur throughout the control range due
to linkage geometry inaccuracies. The Balance function allows
the servo output of the master servo to be adjusted at 7 points
throughout the range, compensating for any linkage geometry
inaccuracies. Think of Balance as a curve mix that allows the
master channels to be independently adjusted at seven different
points, allowing a perfect bind-free setup throughout the control
stroke.
To Program the Balance Function
1. Highlight and select Balance in the FUNC.LIST to obtain the
Balance display.
2. Note that the Balance screen will display the functions
that a programmed in the Wing Type. If Flaperon only is
programmed only one aileron column will appear in the
balance screen. If 4- ailerons are selected then two columns
will appear in the balance screen. This also applied to the
dual elevator and rudder functions.
3. Using the roller highlight the desired position and press
the roller to access the value. Rotate the roller to change
the output position that is selected. The range is +100 to
-100. Repeat this for all positions until no binding occurs
throughout control travel.
A-38
Note: Balance is available in the FUNC.LIST only if the
FLAPERON, Delta or 4-Aileron is selected in the Wing
Type or if any of the dual functions (i.e. dual elevator, dual
rudder etc.) is activated in Wing Type.
44: Gyro Sensor
Note: In order for the GYRO System to appear in the
FUNC.LIST, the AUX2 and/or the AUX3 channels must be
set to GYRO in the Devic.SEL screen.
The 12X features a Gyro Gain system that allows in-flight
selection of 3 gyro gain settings for up to two separate gyros
or up to five gyro gain settings assigned to flight modes. The
system provides for fixed gain values and has settings for
normal or tail lock gyros. Gyro gains can be assigned and
selected via a three-position switch or with Flight Modes.
Note: This function is designed to be used only with gyros
that have in-flight proportional gain adjustment capability.
Single and dual rate gyros that use a potentiometer to
adjust the gain will not work with this function.
Note: If one set of gains for a gyro is set to 0%, (in
normal gain mode)then the gyro can be switched off
during flight.
Gyro Connections
Note: The Devic.SEL function must be programmed to
GYR, GEAR, AUX2 and/or AUX3.
Plug the gain connector of one gyro into the AUX2 port of the
receiver. Plug the gain connector of another gyro (if used) into
the AUX3 of the receiver. If only one gyro is to be used, connect
its gain to either AUX2 or AUX3.
Gyro Gain
To Access the Gyro Sensor
1. Highlight and select GYRO SENS. in the FUNC.LIST.
2. Highlight MANUAL then decide which switch to use to
control gyro gain. Highlight and select AILE D/R, ELEV D/R,
FLAP SW, [email protected] or AUTO (for flight mode).
3. Two types of gyro adjustments are provided, Normal and
Tail Lock. Highlight and select the desired type of gyro
that will be used. If heading lock is selected, note that a T
or N is available for each gain setting. If T is selected, all
values will result in the gyro being in tail lock mode. If N is
selected, all values for that gain will be in normal mode.
Note: For most airplane applications normal mode is
recommended. Also note the Time Lag is available in Tail
lock mode. Time lag is available when switching from tail
lock to normal mode to prevent the servo attached to the
gyro from jumping abruptly when switching from tail lock
to normal mode.
4. Each gyro has 3 available gain settings (or up to five if extra
flight modes are selected). They are labeled Pos0, Pos1,
Pos2, Pos3 and Pos4 with a percentage next to each. They
correspond to the positions of a 3-position switch where
0 represents the switch being in the upper position; 1
represents the middle position; and 2 represents the lower
position.
5. Use the Selector to highlight and select the number 0
position for each gyro and set the percentage to the desired
gain value.
6. Select the number 1 gain for each gyro and set it to the
desired value.
7. Select the remaining gain values.
A-39
45: Governer
Note: Flight modes must be activated in Device Select to
access the governor screen.
The 12X features a Governor program that can be activated in
the Device Select screen. The Governor program is designed to
be used with most currently available Governor systems, and
allows for independent rpm settings for each of the active flight
modes.
To Activate the Governor Screen
1. In the Devic.SEL function use the Selector to highlight
under OUT the GEAR, Aux 2 or Aux 3 channel. GEAR, Aux
2 or Aux 3 must be programmed to GOV in order to access
the governor function. The Governor program will now be
visible in the Function Mode List.
To Access the Governor Screen
1. Highlight and select Governor in the FUNC.LIST.
2. Highlight the desired flight mode and adjust the value using
the selector. Repeat this for all flight modes.
A-40
62: Aileron to Rudder
The 12X features a preprogrammed Aileron-to-Rudder mix. This
mix causes the Rudder to deflect when the Ailerons are moved.
This is useful for some types of aircraft that have adverse yaw,
(right aileron results in a left yaw). By programming aileron
to rudder mix in the same direction the airplane will make
coordinated turns using ailerons only.
To Program Aileron-to-Rudder Mixing
1. Highlight and select AILRUD M in the FUNC.LIST to
obtain the Aileron-to-Rudder mix display.
2. There are 2 sets of mixing values available – Pos0 and
Pos1. If the Pos0 values are left at 0% then the mixer may
be turned on and off – Pos0 would be off and Pos1 would
be on (this can be reversed by leaving the Pos1 values at
zero and putting values into Pos0). Highlight and select L
next to Pos1 and set the value to give the desired amount of
Left Rudder. A negative value will reverse the direction.
4. Scroll down to the bottom line of the display to select the
Flight Mode and/or switch(s) that is to be used to turn
the mixer on and off. The example below shows Flight
Mode 2 set to Pos1, turning on the Aileron-to-Rudder mix.
The throttle may also be used to turn the mixer on and
off by highlighting and selecting THRO STK and setting
the percentage of throttle to the point where the mixer is
switched on/off.
3. Highlight and select R next to Pos1 and set the value to
give the desired amount of Right Rudder. A negative value
will reverse the direction.
A-41
Note: The Pos0 values can also be set to something other
than zero causing a different amount of Rudder deflection
to occur when there is Aileron input. One or more switches
can then be selected to switch between the two sets of
values. With this setup there will always be some mixing,
as indicated by either Pos0 or Pos1, and the mixing
cannot be turned off.
63: Elevator to Flap
The 12X features a preprogrammed Elevator-to-Flap mix.
The mixer causes the Flaps (or Flaperons) to move when the
Elevator is moved, resulting in tighter looping maneuvers, or
to provide some Aileron reflex for some 3D maneuvers such as
Harriers. Typically, the flaps are set to travel downward with up
Elevator and to travel upward with down Elevator. The direction
that the flaps travel with Elevator input can be changed by using
positive and negative values.
To Program Elevator-to-Flap Mixing
1. Highlight and select ELEFLP M in the FUNC.LIST to
obtain the Elevator-to-Flap mix display.
2. There are 2 sets of mixing values available – Pos0 or Pos1.
If the Pos0 values are left at 0% then the mixer may be
turned on and off – Pos0 will be OFF and Pos1 will be ON
(this can be reversed by leaving the Pos1 values at zero
and putting values in Pos0). Highlight and select DN next
to Pos1 and set the value to give the desired amount of
Flap travel in the Down direction when full Up Elevator is
applied.
3. Highlight and select UP next to Pos1 and set the value to
give the desired amount of Flap travel in the UP direction
when full Down Elevator is applied.
4. Scroll down to the bottom line of the display to select the
Flight Mode(s) and/or switch(s) that is to be used to turn
the mixer on and off. The throttle may also be used to turn
the mixer on and off by highlighting and selecting THRO
STK and setting the percentage of throttle to the point where
the mixer is to switch between On and Off.
A-42
64: Rudder to Aileron/Elevator Mix
The 12X features a Rudder to aileron/ elevator mix that is used
to eliminate roll and pitch coupling when rudder is applied.
Two mixes are available and independent mix values can be
assigned for each direction. Various switches and flight modes
as well the throttle stick and other stick positions (SPS) can be
used to select either of the mixes. If one of the mixes has a 0%
value then selecting that mix will turn off the mix.
To Program the Rudder-to-Aileron Mix
1. Highlight and select RUDD- A/E in the FUNC.LIST to obtain
the Rudder to Aileron/ Elevator display.
2. Scroll to the desired value (aileron or elevator, right or left,
position 0 or 1) and press the roller to select that value.
Rotate the roller to program the desired mix value. Note
that positive and negative values are available to reverse the
direction of the mix.
Note: If a mix value is desired to always be active (on),
then program that mix value in Pos0 and leave all switches
set to Pos0.
3. To select the desired switch, flight mode switch position or
throttle position that will activate mix value Pos0 and Pos1,
highlight the desired switch and choose 0 or 1. Note: Pos1
has priority over Pos0.
A-43
66: Flap System
The 12X features a three-position Flap System with Elevator
compensation, programmable Delay, and an Auto Land feature.
Its purpose is to allow the flaps to be programmed to three
different positions, normally full flap, half flap and no flap or
fully retracted position.
Because flaps generally causes a change in pitch (Elevator
trim), the Flap System provides for setting an Elevator deflection
for each flap position. This is called Elevator Compensation.
There is also a programmable Delay in .1-second increments
up to a maximum of 2 seconds. The Delay determines how long
it takes for the Flaps and Elevator to reach their positions. This
delay function insures that the Flaps and Elevator reach their
positions at the same time resulting in smooth Flap deployment
and retraction with minimal pitch change.
Note: The Flap System is available in the FUNC.LIST only
if SYS. is selected on the OUT line next to FLAP in the
Device. Select function in the SYSTEM Menu.
The Auto Land feature, if implemented, automatically retracts
the Flaps and Elevator compensation when the throttle is raised
above a specified throttle position. This can be useful during
a missed landing approach when a go-around is required. The
Flap System allows the Flaps to be deployed using the Flap
Switch, Flight Mode switch or a combination of both.
To Program the Flap System
1. Highlight and select FLAP SYS. in the FUNC.LIST to obtain
the Flap System display.
1. If Auto Land is to be used, scroll to INH under AUTO LAND
and select it with the Selector. INH will change to ACT when
selected and toggles between ACT and INH each time the
Selector is pressed.
2. Scroll down to THRO and press the Selector to show the
throttle percentage. Rotate the selector until the throttle
percentage (0–100%) is equal to where the Auto Land
feature is to retract the Flaps and Elevator compensation.
It is recommended that the throttle position be set very high at
first (between 90–99%) to give the aircraft a chance to regain
some speed before the Flaps actually retract. As the Flaps
retract, lift will decrease and the stall speed of the aircraft will
increase and may cause a crash if the airspeed is too low. When
there is a missed approach, advance the throttle slowly up to
about 90% and wait until the aircraft picks up some speed
before advancing the throttle to full, causing the Flaps to retract.
A-44
Flap
The FLAP values correspond with how far the flaps deflect when
in the NORM, Mid, and Land positions. Generally the NORM
position represents normal flying where the flaps are fully
retracted. The Mid position is typically used for half flaps and
the Land position is typically used for full flap for landing.
1. With the Flap switch in its uppermost (Normal) position (no
flaps deployed), scroll to the NORM parameter under FLAP
on the display. Select the value with the Selector and adjust
its value to bring the flaps to their normal flying position
(no flaps deployed).
2. With the Flap switch in the mid position, scroll to Mid
under FLAP on the display and select it. Adjust the desired
percentage to deflect the flaps the desired amount.
3. Put the Flap switch in the lowermost Land position. Scroll
to Land under FLAP on the display and select it. Adjust the
percentage to deflect the flaps to the desired position.
ELEV – Elevator Compensation
The ELEV values represent the Elevator deflection that will occur
when the Flaps are deployed to their various positions. Some
trial and error will be required to arrive at the exact values, but
once properly adjusted, the aircraft will assume the proper pitch
attitude for all flap positions.
1. Adjust the Elevator compensation values (ELEV) to the
desired values for each switch position as per the flaps
above.
Flight Modes
If Flight Modes have been activated in the Device SEL function,
then FM0, FM1 and FM2 (and 3 and 4 if extra was activated)
will appear along the right side of the Flap System display to
represent the 3 Flight Modes. Each of the Flight Modes can
be assigned one of the Flap values (NORM, Mid, or Land),
so when that Flight Mode is selected during flight, the Flaps
deploy to that position. SW is also an option. When SW is
selected for a Flight Mode, flap operation is controlled by the
Flap switch when in that Flight Mode.
If Flight Modes have not been activated, skip this portion of the
Flap System.
1. For each Flight Mode, highlight and select FM0-FM2 and
select either a flap position (NORM, Mid, Land) that the
flaps are to assume when in that Flight Mode, or select SW
if the Flap switch is to control the flaps when in that Flight
Mode.
Delay
The Delay feature determines how long it takes for the flaps
and Elevator to reach their positions. When the delay function
is programmed, The 12X automatically times the Flaps and
Elevator so that they reach their positions at the same time,
resulting in smooth Flap deployment with minimal pitch
change. The Delay is adjustable in .1-second increments up to
a maximum of 2 seconds.
1. Highlight and select Delay in the Flap System display using
the Selector. Then use the rotary to select a delay between
.1- second and 2 seconds.
A-45
51 thru 58: Programmable Mixers
Programmable mixers are programmed to cause a second
or slave channel to react as a result of providing input to
the primary or master channel or to cause a channel to be
controlled by moving a switch or lever. Programmable mixes
are typically used to activate special aircraft functions like
smoke systems, speed brakes, steerable nose gear, bomb drops,
idle-up, etc. or to alter flight characteristics, for example down
elevator at low throttle for aerobatic aircraft such that the aircraft
tracks perfectly on the down lines at low throttle.
The 12X provides 3 Standard programmable mixes (PROG.
MIX1 - PROG.MIX3) and 5 Multi-Point or Curve programmable
mixes (PROG.MIX4 - PROG.MIX8). Multi-Point (or Curve)
Mixing provides the ability to program a customized curve that
the Slave channel will follow as it reacts to the Master channel’s
input. Multi Point mixes are different from Normal Mixes in
that Normal Mixing results in a linear movement of the Slave
channel in relation to the Master. With Multi-Point Mixing there
are up to 8 points that can be adjusted to control the position
of the Slave channel, providing the ability to custom tailor the
output of the slave channel.
The primary channel is called the Master channel, while the
channel that reacts to the Master is called the Slave channel.
Mixes are fully programmable, allowing any of the 12 channels
to be Master, Slave or both (a channel can be mixed to itself).
Trimmers and levers can also be used as a master and are
extremely useful for programming proportional channel to be
operated via a trimmer or lever. Additionally programmable
mixes can always be on, or turned off and on via a programmed
switch, Stick position or flight mode. The Snap Roll/ Trainer,
switch (momentary switch SNPT) can also be programmed as
the Master channel.
If dual functions have been activated in the Device Select
screen, the following slave channels are available: AILV, FPRN,
FROL, and RUDV, these functions allow the ailerons to be
moved as flaps, flaps to be moved as ailerons, elevators to be
moved as ailerons, rudders to be moved as speed brakes, both
in or both out..
Additionally there are 2 options for Master channels:
“#” (pound sign), these Master channels are Origin type mixes.
These include #THRO #AIL, #ELE, and #RUD. Origin mixing
bypasses any other mixing that might affect that channel,
such as throttle curves, exponential, travel adjust or other
programming, and uses the stick position only to control the
mix.
“+” sign, these Master channels are trim include type mixes.
These include THR+, ELE+, AIL+, and RUD+. Trim Include
mixes include the trim of the Master channel as well as any
other mixing to the Master channel to control the Slave channel
of the mix.
Standard Programmable Mixer - (Std. Prog Mixer)
The 12X has 3 standard programmable mixers that allow for
linear mixing of a Master channel to a Slave channel. The
standard mixers are PROG.Mix1, Mix 2 and Mix 3.
These mixes provide for 2 sets of mixing values named Pos0
and Pos1. If one set of values is set to 0% then the mixer can
be turned On and Off with a stick, switch or lever. Each set of
mixing values is comprised of 2 percentages to accommodate
movement of the Master channel in both directions. This is
shown in the illustration below where there is an upper and
lower percentage for both Pos0 and Pos1.
A mix can be made to always be on by setting Pos0 values only
and not selecting any switches to switch between the Pos0 and
Pos1 values.
A-46
Master Channel - (Std. Prog Mixer)
The Master channel is the primary or controlling channel. The
default for both the Master the Slave channel is THRO. The
Master channel is selected by highlighting and selecting this
parameter to obtain a list of channels and then selecting the
Master channel from the list.
Note: There are 4 channels that appear more than once.
They are Throttle, Aileron, Elevator and Rudder. Since
these channels can be influenced by Dual Rate and
Exponential settings, they are included in the list twice
- once where the D/R and EXP settings are in effect and
again where the D/R and EXP settings are ignored. The
second time they are listed, there is a special designator to
indicate that these channels can also be used as a Master
while bypassing any Dual Rate and Exponential settings
that may be associated with them. They are designated
by “#” (pound sign) in front of the name - #THRO, #AILE,
#ELE, and #RUD. When one of these channels is selected
as the Master, all D/R, EXP and Curve settings associated
with the Master are ignored during the mixing operation.
Instead, the mixer reads only the physical position of the
stick to perform mixing.
A (+) behind the channel indicates a trim include function. By
selecting a channel with the (+) the trim lever affects both the
master and slave channels.
A-47
Note: Some programmable mixes have + appearing after
a specific channel and other mixes have # before that
specific channel. Choose the programmable mix that offers
the type of mix (origin of trim include) that you desire.
Slave Channel - (Std. Prog Mixer)
The Slave channel is the secondary receiving channel and will
move according to the program mix in relation to the Master
channel. The default for both the Master the Slave channel is
THRO.
The Slave channel is selected by highlighting and selecting
this parameter to obtain a list of channels and then selecting
the Slave channel from the list. The list contains each of the 12
channels in the system and CANCEL.
Switch Position
The right side of the Programmable mix screen displays the
available switch options. If you choose to have a switch control
the mix, either on/off or have two mix values, highlight and
select the desired switch(s) and select position 0 or 1. Each
standard programmable mixer has two positions - Pos0 and
Pos1 and each position has 2 percentages (upper and lower)
to accommodate mixing when the Master is moved in both
directions. Note that Pos1 has priority over Pos0.
A-48
Offset
Offset defines the position where the mixer changes directions.
The Offset is defaulted to center position or 0 and this is most
commonly used. With a 0 Offset, if the Rudder is the Master,
moving the rudder stick to the left of center causes a mix in one
direction while moving the rudder stick to the right of center
causes a mix in the other direction. Directions correspond to the
upper and lower percentages for Pos0 and the upper and lower
percentages of Pos1. The amount of mix and actual direction
that the slave moves is determined by the Pos0/Pos1 values.
The Offset applies to both Pos0 and Pos1 settings.
The Offset may be changed by highlighting and selecting
Offset and adjusting either a positive (+) or negative (-) value.
A positive percentage moves the offset in one direction from
center while a negative percentage moves the Offset in the other
direction from center.
Mix Values
Each standard Programmable mixer can have two sets of mixing
values - Pos0 and Pos1. Each set can have 2 percentages which
control movement of the slave when the master is moved in
each direction. A switch can be selected to switch between the
Pos0 and Pos1 percentages.
The Pos1 settings are identical to the Pos0 settings and
determine how far, and in which direction, the slave channel
moves when the master is moved above and below the offset
(the Master moving in both directions) when the switch is in a
position to select the Pos1 values.
The Pos0 settings determine how far, and in which direction,
the slave channel moves when the master is moved above and
below the Offset (the Master moving in both directions) when
the switch is in a position to select the Pos0 values.
To enter Pos1 values, highlight and select Pos1, move the
Master channel control (stick, lever or switch) in one direction
and set the percentage and then move the Master channel
control in the other direction and set its value.
To enter Pos0 values, highlight and select Pos0, move the
Master channel control (stick, lever or switch) in one direction
and set the percentage and then move the Master channel
control in the other direction and set its value
A-49
CLR Button - (Std. Prog Mixer)
Note: Pressing the CLR button while a modifiable
parameter is selected will reset the parameter to its default
value. Pressing the CLR button when either the Master or
Slave is highlighted Inhibits the entire mixer and it is no
longer functional.
To Inhibit a Mix
Highlight either the Master or Slave and press the CLR button
to completely disable a mixer.
Multi-Point Programmable Mixer
There are 5 Multi-Point Programmable Mixers in the 12x, Prog.
Mix4 thru Prog.Mix8. They differ from the standard mixes in
that they allow non-linear mix response from the Master to
the Slave. This is possible because the mixer uses up to 8
points to define the position of the slave channel relative to the
Master channel at up to eight selectable points. As the Master
reaches each point, the Slave response position can be defined
independent of other point settings.
Master Channel
The Master channel is the primary channel, lever or trim lever.
The Master channel is selected by highlighting and selecting
this parameter to obtain a list of channels and then selecting the
Master channel from the list.
There are 4 channels that appear more than once. They are
Throttle, Aileron, Elevator and Rudder. Since these channels
can be influenced by Dual Rate, Exponential, and Throttle Curve
settings, they are included in the list twice - once where the
D/R and EXP settings are in effect and again where the D/R
and EXP settings are ignored. The second time they are listed,
there is a special designator to indicate that these channels can
also be used as a Master while bypassing any Dual Rate and
Exponential settings that may be associated with them. They
are designated by “#” (pound sign) in front of the name - #FLP,
#AIL, #ELE, and #RUD. When one of these channels is selected
as the Master, all D/R, EXP and Curve settings associated with
the Master are ignored during the mixing operation. Instead, the
mixer reads only the physical position of the stick to perform
mixing.
A (+) behind the channel indicates a trim include function. By
selecting a channel with the (+) the trim lever affects both the
master and slave channels.
A-50
Slave Channel
This is the Slave channel that will move according to the
program mix in relation to the Master channel.
The Slave channel is selected by highlighting and selecting
this parameter to obtain a list of channels and then selecting
the Slave channel from the list. The list contains each of the 12
channels in the system.
Point Names/Numbers
The points that can be adjusted are listed vertically by name and
are also displayed by number along the bottom of the graph.
Change the value of a point by highlighting and selecting the
point name and dialing-in the desired percentage.
Current Point Setting
This list shows the setting for each of the 8 adjustable points
(Point-L, 1, 2, 3, 4, 5, 6, 7, H). The value of each point
determines where the point is positioned vertically on the graph,
which dictates the Slave servo position relative to the master.
The point values can be set from -100 to +100. A value of 0
indicates the Slave’s center or neutral position. The overall
travel of the slave channel is affected by the Travel settings
described in the TRVL ADJ. function.
The value for a point can be changed by highlighting and
selecting the Point Name to the left of the point value and then
dialing-in the desired value.
Pressing the CLR button when a point value is highlighted
resets the point to original settings. The original settings are:
Vertical Line
The Vertical line on the graph shows the current Master channel
position. When the Master channel is deflected fully in one
direction, the line is to the extreme left over Point-L, when it is
at neutral it is in the center over Point-1, and when it is fully
deflected in the other direction, the cursor is at the extreme right
of the graph over Point-H. Where the vertical line intersects
the Curve/Line over a given point defines Slave servo position,
which is equal to the value assigned to that point.
A-51
Multi-Point Programmable Mixer
Graph
The graph illustrates the mixing curve. The X-Axis (horizontal
plane) represents Master channel movement. The Y-Axis
(vertical plane) represents the Slave servo movement where the
bottom 1/2 of the graph is one direction from neutral and the
top portion of the graph is the other direction.
Points That Can Be Added and Adjusted
Curve mixes are defaulted to three points (L, 1 and H). Up to
five additional points can be added. To add a point, move the
master channel in the desired position until STR appears on the
left bottom of the screen. Pressing STOR will store a new point
at that position.
Note: To eliminate a point press ERAS (bottom left of the
screen) when the point is highlighted.
Exponential
The Exponential function blends the Curve between the points
on the graph to provide a smooth response. The default value is
OFF. To turn it on and smooth the mixing curve, highlight and
select OFF and it will toggle to ON.
Slave Channel Position
The Slave servo position next to OUT at the bottom left of the
display is expressed in values from -100 to +100, with 0 being
neutral or center. It represents the servo travel that corresponds
to the present Master channel position.
Master Channel Position
The Master channel position is shown on the bottom line of the
display next to IN and is expressed in values from 0 to 100 with
50 being the center or neutral position. It represents the present
Master channel position.
A-52
Switch Select
There are numerous switches that can be used to switch
between the Pos0 and Pos1.
Note: If the upper and lower settings for Pos0 or Pos1
are left at 0% the mixer can be turned on and off with
the switch. In addition, if Flight Modes are activated in
the Devic.SEL function, then flight mode switches may
be selected. Also Switch positions can be used to select
between Pos0 and Pos1.
To select a switch that will switch between the Pos0 and Pos1
values, highlight and select the switch name and it will toggle
between Pos0 and Pos1.
CLR Button
Pressing the CLR button while a modifiable parameter is
selected will reset the parameter to its default value.
Note: Pressing the CLR button when either the Master or
Slave is highlighted inhibits the entire mix.
LIST Button
Press the LIST button to return to the FUNCTION List, or rotate
the rotary selector until L.S.T. appears next to LIST and select it
to return to the SYSTEM Menu.
ENT Button
Pressing the ENT button returns to the Main Display.
TO Inhibit a Mixer (turn it off entirely)
Highlight either the Master or Slave and press the CLR button
to completely disable a mixer.
A-53
67: Aileron-to-Flap Mix
Aileron-to-Flap mix causes the flaps to move in unison with
the ailerons. This function gives added roll response by mixing
ailerons to flaps such that the entire trailing edge functions as
an aileron.
Note: This function is only available when Dual Flap is
assigned in the Wing Type function.
To access Aileron-to-Flap mix, in FUNC.LIST rotate the Selector
until AILFLP M is highlighted. Press the Selector to access
the Aileron-to-Flap mix.
Note: Two Aileron-to-Flap mix values are available—Pos0
and Pos1. Switches are available at the right of the screen
that allow the selection of Pos0 or Pos1.
Note: Position 1 always has priority over position 0. Press
the LIST button to return to the Function Mode screen.
A-54
68: Pitch Curve
The Pitch Curve is used to control variable pitch propellers.
The Pitch function works nearly identically to a programmable
curve mix, allowing up to 8 points to be stored and adjusted
throughout the curve. Two curves are available (Pos0 and Pos1)
and are selectable with various switches, flight modes, throttle
position or Stick positions (SPS). An Exponential function is
available that smooths the pitch curve. Pitch must be assigned
to Gear, Aux2 or Aux 3 channels in device select to be able to
access the Pitch function. The Pitch curve mixes the throttle
channel to the channel that is selected as PIT in the device
select mode.
Note: PIT (Pitch) must be selected in Device select for the
GEAR, AUX2 or the AUX 3 channel to allow access to the
Pitch Curve Function.
Point Names/Numbers
The points that can be adjusted are listed vertically by name
(Point-L, 1, 2, H, etc.) and are also displayed by number on the
graph.
Change the value of a point by highlighting and selecting the
point name and adjusting the desired percentage.
Current Point Setting
This list shows the setting for each of the 8 adjustable points
(Point-L, 1, 2, 3, 4, 5, 6, H). The value of each point determines
where the point is positioned vertically on the graph, which
dictates the Pitch servo position relative to the throttle. The
point values can be set from 0 to +100.
The value for a point can be changed by highlighting and
selecting the Point Name to the left of the point value and then
adjusting the desired value.
Pressing the CLR button when a point value is highlighted
resets the point to original settings.
A-55
Vertical Line
The vertical line on the graph shows the current throttle channel
position. When the throttle channel is deflected fully in one
direction, the line is to the extreme left over Point-L, when it
is at neutral it is in the center over Point-1 and when it is fully
deflected in the other direction the cursor is at the extreme right
of the graph over Point-H. Where the vertical line intersects the
Curve/Line over a given point defines the pitch servo’s position,
which is equal to the value assigned to that point.
Graph
The graph illustrates the pitch curve. The X-Axis (horizontal
plane) represents throttle channel movement. The Y-Axis
(vertical plane) represents the Pitch servo movement.
Points That Can Be Added and Adjusted
The Pitch Curve is defaulted to three points (L, 1 and H). Up to
five additional points can be added. To add a point, move the
throttle stick in the desired position until STOR appears on the
left bottom of the screen. Pressing STOR will store a new point
at that position.
Note: To eliminate a point press ERAS (bottom left of the
screen) when the point is highlighted.
Exponential
The Exponential function blends the Curve between the points
on the graph to provide a smooth response. The default value is
OFF. To turn it on and smooth the mixing curve, highlight and
select OFF and it will toggle to ON.
Pitch Channel Position
The Pitch servo position next to OUT at the bottom left of the
display is expressed in values from 0 to +100. It represents the
servo travel that corresponds to the present Throttle Channel
position.
Throttle Channel Position
The Throttle channel position is shown on the bottom line of the
display next to IN and is expressed in values from 0 to 100 with
50 being the center or neutral position. It represents the present
Throttle channel position.
A-56
Switch Select
There are numerous switches that can be used to switch
between the Pos0 and Pos1. Note: if the upper and lower
settings for Pos0 or Pos1 are left at 0% the mixer can be turned
on and off with the switch. In addition, if Flight Modes are
activated in the Devic.SEL function, then flight mode switches
may be selected. Also Switch positions can be used to select
between Pos0 and Pos1.
To select a switch that will switch between the Pos0 and Pos1
values, highlight and select the switch name and it will toggle
between Pos0 and Pos1.
CLR Button
Pressing the CLR button while a modifiable parameter is
selected will reset the parameter to its default value.
Note: Pressing the CLR button when either the Master or
Slave is highlighted will inhibit the entire mix.

H-11
83: Trim System
The Trim System function adjusts the sensitivity of the 12X
trims, hovering throttle and hovering pitch trim levers and the
high pitch lever. The digital trims are adjustable from 0–10
with 10 being the coarsest adjustment and 0 being trim off.
Adjusting the digital trim values has no effect on the total trim
travel (unless 0 is selected), however, it affects the resolution
of each trim input. When the value is set to 10, each click of
trim adjusts the servo output by 10us and there are only 10
trim increments from center to each end. When set to 5, the
output is changed 5us per trim step and there are 20 trim
increments from center to each end. When set to 1, each click
of trim changes the servo output by 1us and there are 100 trim
increments. When set to 0 the trim levers cease to function
effectively turning off the trim function. The right and left trim
levers Are adjustable from 0 to 200 and can be turned on/ off.
When adjusted to above 100% the trimmer functions as a threeposition switch. Reducing the value increases the number of
output positions.
When adjusting the digital trims (AILE, ELEV, RUDD), the total
trim travel does not change – only the number of increments
(beeps) changes, which makes for finer or coarser trim
movements. When adjusting the analog throttle trim, and the
high pitch trim, however, the total trim travel is actually reduced
when set to less than 100%.
It is recommended to use a fairly coarse setting, such as the
factory default 4, when test flying a model for the first flights in
order to be able to trim it quickly, and then use a finer setting,
such as 3–1, for final precision trimming.
LST Trim
The LST trim feature has two options, LST and normal. In
normal, when making trim changes using the Aileron elevator
or rudder digital trims, the center as well as the end points is
affected by the trim values ( i.e. right trim causes the center, the
right end point and the left end point to all shift to the right).
When LST is activated, only the center position is trimmed
(i.e. the center is shifted to the right but the end points are not
affected). This is useful for helicopters that have a hard stop end
point to prevent over travel caused by trim or if it’s desired to
have trim changes not affect the total roll pitch or yaw rate. LST
trim is normally turned on for helicopters.
H-12
To Adjust the Trim Rates
1. Highlight and select TRIM SYS. in the SYSTEM MODE to
acquire the Trim System function.
2. Highlight and select the trim that is to be changed and
use the Selector to set a value of 1–10 (1 = finest, 10 =
coarsest; Note: the Flap and AUX trims can be turned off or
on by selecting On or Off).
3. Repeat for other trims as desired.
To Select the LST Trim Function
1. Highlight and select the desired channel (AILE, ELEV or
RUDD) next to (TYPE) LST and press the roller to select
LST or NORM.
3. Repeat for other channels as desired.
H-13
91: Stick Position Switch
The Stick Position Switch function allows the throttle, aileron
elevator or rudder stick positions to be preprogrammed to turn
on/off mixes or the timer. Four stick position programs are
available and one or more can be assigned to various mixes or
functions. The stick position that turns the Stick Position switch
on/off is selectable as well as the direction to turn on/off. Also
a symmetrical option is available that allows the function to
be turned on with a preprogrammed equal right or left (up or
down) stick position.
To Program a Stick Position Switch
6. A symmetrical function is available that allows the stick
position to be turned on/off as the stick is displaced
symmetrically in either direction. It’s necessary to first
program a value in the POS then highlight the SYM

press to access. Next, roll the selector to the desired delay
position, and press the selector to store. A good starting
value is .75 (3/4) of a second.
H-31
18: Throttle Curves
The 12X offers up to five (5) separate throttle curves with up to
eight adjustable points per curve. This function allows you to
customize the throttle curve to maximize engine performance
at any particular pitch setting. Once the throttle curves are
established, each can be activated in flight using the 3-position
flight mode switch. If the additional 2 flight modes (numbers 3
and 4) have been activated in the Device Select portion of the
system mode, an additional switch will be used to activate these
modes and two additional throttle curves will be available.
Positions 1 and 2 (Stunt 1 and Stunt 2) are typically used for
forward flight and 3D maneuvers. Optional flight modes 3 and 4
are also designed for use with aerobatic maneuvers and forward
flight.
Note: The throttle trim and hovering throttle trimmer
are only operable when the flight mode switch is in the
normal position. In the 1, 2, 3, 4 or hold positions, these
two functions have no effect. Also, adjusting the hovering
throttle trimmer and throttle trim has no effect on the input
values of the throttle curve. Each of the eight points of the
throttle curve is independently adjustable from 0–100%.
The flight mode switch offers three selectable positions:
• N=Normal
• 1=Stunt 1
• 2=Stunt 2
• Extra flight modes
• 3=Stunt 3 (optional)

on the graph to provide a smooth response. The default value is
OFF. To turn it on and smooth the mixing curve, highlight and
select OFF and it will toggle to ON. An Expo function can be
selected independently for each flight mode.
Trim (Mechanical Trim Lever)
In the Normal mode only, a throttle trim is available that allows
the throttle trim value to be adjusted. The trim value adjusts
the overall trim travel of the throttle only at low throttle in the
normal mode. This trim value adjustment is helpful in adjusting
the sensitivity of the throttle trimmer. To adjust the throttle trim
authority, highlight TRIM and adjust the value using the roller.
Note the onscreen graph can be used to indicate the trim value
changes.
Note: The throttle trim lever is only active when the flight
mode switch is in the normal position. The throttle trim
lever has no effect on flight modes 1, 2, 3, 4 or in throttle
hold.
Hovering Throttle
Hovering Throttle increases or decreases the servo output via
the trimmer or knob for the selected points set for the throttle
curve. Use of the hovering throttle trimmer/ knob to shifts the
curve upward or downward to advance or reduce rpm in hover.
The HOV function can be activated at each point by selecting
ON under HOV.
Note: The Hovering Throttle has no effect on flight mode
switch positions 1,2, 3,4 or Hold.
H-33
24: Servo Speed
The 12X provides the ability to adjust the speed of servos for
each channel in each direction. The speed may be reduced
(servo slowed) from its normal speed but it cannot cause a
servo to move faster than its rated specifications. Each servo
can have 2 sets of speeds in each direction that are Flight Mode
or switch selectable.
To Adjust Servo Speed
1. Highlight and select SRV. Speed. Speed FUNC.LIST.
2. Select SW SEL and press the roller to access Switch Select.
If only one servo speed is desired then all selectable switch
positions in this screen should be P0. If two servo speeds
are desired, then assign the desired switch that will change
the servo speed to P1. Return to the main screen.
3. If a single set of servo speeds is desired, make sure the
display is showing Pos0. If it is not, select Pos1 and
change it to Pos0. Highlight and select the channel and
direction for each servo that is to be adjusted. Once a
direction for a servo is selected, the servo speed may be set
so the servo travels from .193 seconds for 60 degrees of
rotation to 16.4 seconds for 60 degrees of rotation. Adjust
the speed of each servo until the desired speed is obtained.
4. If 2 sets of servo speeds are desired that are Flight Mode or
switch selectable, one set of values is set to NORM for all
channels, slowing of servos can be turned off by selecting
the position (Pos0 or Pos1) that has the NORM values.
Highlight and select Pos0 and change it to Pos1, and then
highlight and select the channel and direction for each
servo that is to be adjusted. Once a direction for a servo is
selected, the servo speed may be set so the servo travels at
the desired slower rate. Switch between Pos0 and Pos1 to
view and adjust the 2 sets of values for each servo.
H-34
Note: Pos1 always has priority over Pos0. In other words,
if multiple switches are selected and one of the switches
is in its Pos1 position, then all other switches are ignored
and the Pos1 values are in effect.
42: Mix to Throttle
The 12X Cyclic-to-Throttle function is designed to add throttle
to prevent main rotor rpm decay resulting from load changes
placed upon the engine when an Aileron, Elevator or Rudder
control is given.
The most common use for Cyclic-to-Throttle mixing is for
Stunt Modes, allowing the main rotor rpm to remain consistent
throughout aerobatic and 3D maneuvers. Normally, Cyclicto-Throttle mixing is not used in Hover (Normal) mode since
control inputs are generally small and much less aggressive.
Note: If a Governor will be used for rpm control, it is not
necessary to use the Cyclic-to-Throttle Mixing, and all
values should be left at the factory default position (0%).
Programming the Cyclic-to-Throttle Function
1. In Function mode highlight the MIX-THRO function. Press
the Rolling Selector to access the MIX-THRO screen.
2. Highlight the desired value to be adjusted with the Rolling
Selector, and then press to open the options box. Roll the

44: Gyro Sensor
Note: To access the gyro function, the Gear, Aux1 or Aux
2 channels must be programmed to GYR in device select
code 17 and the gyro gain lead must be plugged into this
channel.
The 12X offers three different types of Gyro Gain Sensitivity
Adjustments: manual, flight mode or automatic. This feature
gives the user the choice of selecting gyro sensitivity through
the rudder, aileron or elevator dual rate switches (manual),
selecting one of three available gain settings for each flight
mode (FOMD) or automatically selecting a gain for each flight
mode (up to 6 gain settings). The gyro program can be set
up for normal or tail lock gyros. In tail lock mode the value
correlates with the actual percentage of the gyro output. A time
lag feature delays the gain input when switching from tail lock

The Exponential function blends the Curve between the points
on the graph to provide a smooth response. The default value
is OFF. To turn it on and smooth the tail curve, highlight and
select OFF and it will toggle to ON. An Expo function can be
selected independently for each flight mode.
H-38
61: Dual Pitch
Note: This function is only available if the 1 servo NORM
is selected in swashplate type and if the PIT function is
assigned to the GEAR, AUX2 or AUX3 channels in Device
Select.
The Dual Pitch function is designed for use with mechanical
mix helicopters (non-CCPM) where two servos are used
to control the pitch function. Note that this function is only
available if the 1 servo NORM is selected in swashplate type
and if the PIT function is assigned to the GEAR, AUX2 or AUX3
channels in device select. This function is primarily designed
for large industrial use helicopters that require powerful pitch
control. The Dual Pitch function features a trace rate that allows
the servo’s output positions to be accurately matched at 7
points throughout the stroke.
1. To access and activate the Dual Pitch function, highlight
and select Dual PIT. in the FUNC.LIST to obtain the Dual
Pitch display.
2. The display shows the channel that the pitch channel is
mixed to and the points that can be adjusted to match the
servo output of both servos.
3. To change the output of a specific point highlight the
desired point using the selector and press the selector to
access that value.
4. Rotate the roller to adjust the value of the selected point.
H-39
65: Swashplate Mix
The Swashplate Mix screen has several important functions.
These functions include:
Aileron, Elevator and Pitch Authority
This function independently adjusts the maximum travel of
the servos that work in unison for aileron, elevator and pitch
control. If the aileron value is increased, the servos that control
aileron only (the pitch and aileron servos) will increase travel
when the ailerons are deflected and won’t affect pitch or elevator
travel. Conversely if the pitch value is increased all three servos
(aileron, elevator and pitch) will increase travel when the pitch
stick is moved, however, aileron or elevator inputs will not be
affected by this travel increase. To reverse the direction of travel
a – (negative) value can be selected. Adjustment range is from
-125 to +125% (defaulted to +60).
Aileron to Elevator/ Elevator to Aileron Mix
This mix is used to correct for swashplate interactions (i.e.
elevator input resulting in slight roll output). By mixing elevator
to opposite aileron, this interaction can be corrected. Switches
or flight modes can be selected (SE SEL) to turn this mix on/off.
Generally this mix is turned on in stunt modes only.
3D Electronic Cyclic Ring
When active, the 3D electronic cyclic ring prevents the cyclic
servos (aileron, elevator and pitch) from overdriving when a full
elevator and aileron command is given. This is commonly used
for 3D helicopters that are set up to give maximum swashplate
travel for high cyclic rate maneuvers.
Exponential Function
An exponential function is available that compensates for
CCPM servo horn non-linearity at the extremes of travel. It is
recommended that this function always be turned on.
H-40
Elevator-to-Pitch Canceller
This function compensates for the different distance/ time
traveled by the pitch, aileron and elevator servos with elevator
inputs.
Note: The swashplate type must be selected in System
Mode code 34 Swash TYP (see Page H-26).
Accessing the Swashplate Mixing Function
1. Using the Rolling Selector, highlight the Swash MIX
function in function mode to access the Swashplate Mixing
function.
2. To select the aileron, elevator or pitch authority, highlight
the value next to the desired channel and press the roller to
select the value. Rotate the roller to adjust the value.
3. To program an Aileron-to-Elevator or Elevator-to-Aileron
mix, highlight the value below the desired mix AILE/ ELEV
or ELEV/ AILE and press the roller to select the value. Note
that right and left values are available. Rotate the roller to
adjust the value.
5. To activate the 3D cyclic ring, highlight INH next to E-RING
and toggle the roller to ACT.
6. To activate the exponential function, highlight IOFF next to
EXP and toggle the roller to ON.
7. To activate the Elevator-to-Pitch Canceller, highlight INH
under ELEV-PIT. CANCELLER and toggle the roller to ACT.
8. To exit the Swashplate Mixing function, move the Rolling
Selector to highlight LIST, and press.
4. To select a switch, turn on/off the aileron/elevator and
elevator /aileron mix, then highlight SW SEL. A screen will
appear that will allow several switches and flight modes to
be selected to turn on/ off the mix function.
H-41
68: Pitch Curves
The 12X offers up to five (5) separate pitch curves with up to
eight adjustable points per curve. This function allows you to
customize each pitch curve at any particular pitch setting. Once
the pitch curves are established, each can be activated in flight
using the 3-position flight mode switch. If the additional 2 flight
modes (numbers 3 and 4) have been activated in the Device
Select portion of the system mode, an additional switch will be
used to activate these modes.
Positions 1 and 2 (Stunt 1 and Stunt 2) are typically used for
forward flight and 3D maneuvers. Optional flight modes 3 and 4
are also designed for use with aerobatic maneuvers and forward
flight.
Note: The hovering pitch trimmer is only operable when
the flight mode switch is in the normal position. In the 1,
2, 3, 4 or hold positions, this function has no effect. Also,
adjusting the hovering pitch trimmer has no effect on the
input values of the pitch curve. Each of the eight points
of the throttle curve are independently adjustable from
0–100%.
The flight mode switch offers three selectable positions:
• N=Normal
• 1=Stunt 1
• 2=Stunt 2
• 3=Stunt 3 (optional)
• 4=Stunt 4 (optional)
Note: The N (Normal) position is used as the hover pitch
curve.
Accessing the Pitch Curve Function
8. In function mode use the Rolling Selector to highlight the
PIT. CURV function, then press to access. ALL SERVOS
HOLD ? will be displayed. Press YES or NO to access the
Pitch curve screen.
9. Moving the flight mode switch to the desired position
will select the flight mode that will be programmed. The
flight mode will be displayed in the upper left corner of the
screen.
10. Move the Rolling Selector and highlight the desired throttle
point to be adjusted. Press the Rolling Selector to access
the point value, then roll the Rolling Selector to increase
and decrease the point value.
11. To set pitch curves for flight modes, switch the flight mode
to the desired position and the screen will change to that
flight mode.
12. Highlight the desired pitch point that you would like to
adjust and press the roller. Rotate the roller to adjust that
point on the pitch curve.
13. To add a point move throttle stick to the desired position
until STR appears on the left bottom of the screen. Pressing
STOR will store a new point at that position.
Note: To eliminate a point press ERAS (bottom left of the
screen) when the point is highlighted.
14. To exit the Pitch Curve function, highlight the LIST with the
Selector, and press.
H-42
Exponential
The Exponential function blends the Curve between the points
on the graph to provide a smooth response. The default value
is OFF. To turn it on and smooth the pitch curve, highlight and
select OFF and it will toggle to ON.
Hovering Pitch
Hovering Pitch increases or decreases the servo output via the
trimmer or knob for the selected points set for the pitch curve.
Use of the hovering pitch trimmer/ knob to shifts the curve
upward or downward to advance or reduce Pitch in hover.
Note: The Hovering Pitch has no effect on flight mode
switch positions 1,2, 3,4 or Hold.
H-43
51 thru 58: Programmable Mixers
Programmable mixers are programmed to cause a second
or slave channel to react as a result of providing input to
the primary or master channel or to cause a channel to be
controlled by moving a switch or lever. Programmable mixes
are typically used to activate special aircraft functions like
mixture control, pitch to aileron and elevator mixes to correct
for flight dynamics, etc.
The 12X provides 3 Standard programmable mixes (PROG.
MIX1 - PROG.MIX3) and 5 Multi-Point or Curve programmable
mixes (PROG.MIX4 - PROG.MIX8). Multi-Point (or Curve)
mixing provides the ability to program a customized curve that
the slave channel will follow as it reacts to the master channel’s
input. Multi-Point mixes are different from normal mixes in that
normal mixing results in a linear movement of the slave channel
in relation to the master. With Multi-Point mixing there are up
to 8 points that can be adjusted to control the position of the
slave channel providing the ability to custom tailor the output of
the slave channel.
The primary channel is called the master channel, while the
channel that reacts to the master is called the slave channel.
Mixes are fully programmable, allowing any of the 12 channels
to be master, slave or both (a channel can be mixed to itself).
Trimmers and levers can also be used as a master and are
extremely useful for programming proportional channels to
be operated via a trimmer or lever. Additionally programmable
mixes can always be on or turned off and on via a programmed
switch, Stick position or flight mode. The Snap Roll/ Trainer
switch (momentary switch SNPT) can also be programmed as
the master channel.
Additionally there are 2 options for Master channels:
“#” (pound sign), these master channels are origin-type mixes.
These include #THRO #AIL, #ELE and #RUD. Origin mixing
bypasses any other mixing that might affect that channel
such as throttle curves, exponential, travel adjust or other
programming and uses the stick position only to control the
mix.
“+” sign, these master channels are trim-include-type mixes.
These include THR+, ELE+, AIL+ and RUD+. Trim-include mixes
include the trim of the master channel as well as any other
mixing to the master channel to control the slave channel of the
mix.
Standard Programmable Mixer - (Std. Prog Mixer)
The 12X has 3 standard programmable mixers that allow for
linear mixing of a master channel to a slave channel. The
standard mixers are PROG.Mix1, Mix 2 and Mix 3.
These mixes provide for 2 sets of mixing values named Pos0
and Pos1. If one set of values is set to 0% then the mixer can
be turned on and off with a stick, switch or lever. Each set of
mixing values is comprised of 2 percentages to accommodate
movement of the master channel in both directions. This is
shown in the illustration below where there is an upper and
lower percentage for both Pos0 and Pos1.
A mix can be made to always be on by setting Pos0 values only
and not selecting any switches to switch between the Pos0 and
Pos1 values.
H-44
Master Channel - (Std. Prog Mixer)
The master channel is the primary or controlling channel. The
default for both the master and the slave channels is THRO. The
master channel is selected by highlighting and selecting this
parameter to obtain a list of channels and then selecting the
Master channel from the list.
Note: There are 4 channels that appear more than once.
They are Throttle, Aileron, Elevator and Rudder. Since
these channels can be influenced by Dual Rate and
Exponential settings, they are included in the list twice
- once where the D/R and EXP settings are in effect and
again where the D/R and EXP settings are ignored. The
second time they are listed, there is a special designator to
indicate that these channels can also be used as a master
while bypassing any Dual Rate and Exponential settings
that may be associated with them. They are designated by
a “#” (pound sign) in front of the name - #THRO, #AILE,
#ELE and #RUD. When one of these channels is selected
as the master, all D/R, EXP and Curve settings associated
with the master are ignored during the mixing operation.
Instead, the mixer reads only the physical position of the
stick to perform mixing.
A (+) behind the channel indicates a trim-include function. By
selecting a channel with the (+), the trim lever affects both the
master and slave channels.
H-45
Note: Some programmable mixes have + appearing after
a specific channel and other mixes have a # before that
specific channel. Choose the programmable mix that offers
the type of mix (origin of trim include) that you desire.
Slave Channel - (Std. Prog Mixer)
The slave channel is the secondary receiving channel and
will move according to the program mix in relation to the
master channel. The default for both the master and the slave
channels is THRO.
The slave channel is selected by highlighting and selecting
this parameter to obtain a list of channels and then selecting
the slave channel from the list. The list contains each of the 12
channels in the system and CANCEL.
Switch Position
The right side of the Programmable mix screen displays the
available switch options. If you choose to have a switch control
the mix, either on/off or have two mix values, highlight and
select the desired switch(s) and select position 0 or 1. Each
standard programmable mixer has two positions - Pos0 and
Pos1 and each position has 2 percentages (upper and lower)
to accommodate mixing when the master is moved in both
directions. Note that POS 1 has priority over POS 0.
H-46
Offset
Offset defines the position where the mixer changes directions.
The Offset is defaulted to center position or 0 and this is most
commonly used. With a 0 Offset, if the Rudder is the master,
moving the rudder stick to the left of center causes a mix in one
direction while moving the rudder stick to the right of center
causes a mix in the other direction. Directions correspond to the
upper and lower percentages for Pos0 and the upper and lower
percentages of Pos1. The amount of mix and actual direction
that the slave moves is determined by the Pos0/Pos1 values.
The Offset applies to both Pos0 and Pos1 settings.
The offset may be changed by highlighting and selecting
Offset and adjusting either a positive (+) or negative (-) value.
A positive percentage moves the offset in one direction from
center while a negative percentage moves the offset in the other
direction from center.
Mix Values
Each standard programmable mixer can have two sets of mixing
values - Pos0 and Pos1. Each set can have 2 percentages which
control movement of the slave when the master is moved in
each direction. A switch can be selected to switch between the
Pos0 and Pos1 percentages.
The Pos1 settings are identical to the Pos0 settings and
determine how far, and in which direction, the slave channel
moves when the master is moved above and below the offset
(the master moving in both directions) when the switch is in a
position to select the Pos1 values.
The Pos0 settings determine how far, and in which direction,
the slave channel moves when the master is moved above and
below the Offset (the master moving in both directions) when
the switch is in a position to select the Pos0 values.
To enter Pos1 values, highlight and select Pos1, move the
master channel control (stick, lever or switch) in one direction
and set the percentage and then move the master channel
control in the other direction and set its value.
To enter Pos0 values, highlight and select Pos0, move the
master channel control (stick, lever or switch) in one direction
and set the percentage and then move the master channel
control in the other direction and set its value.
H-47
CLR Button - (Std. Prog Mixer)
Note: Pressing the CLR button while a modifiable
parameter is selected will reset the parameter to its default
value. Pressing the CLR button when either the master or
slave is highlighted inhibits the entire mixer and it is no
longer functional.
To Inhibit a Mix
Highlight either the master or slave and press the CLR button to
completely disable a mixer.
Multi-Point Programmable Mixer
There are 4 Multi-Point Programmable Mixers in the 12x, Prog.
Mix4 thru Prog.Mix8. They differ from the standard mixes in
that they allow non-linear mix response from the master to
the slave. This is possible because the mixer uses up to 8
points to define the position of the slave channel relative to the
master channel at up to eight selectable points. As the master
reaches each point, the slave response position can be defined
independent of other point settings.
H-48
Master Channel
The master channel is the primary channel, lever or trim lever.
The master channel is selected by highlighting and selecting
this parameter to obtain a list of channels and then selecting the
master channel from the list.
There are 4 channels that appear more than once. They are
Throttle, Aileron, Elevator and Rudder. Since these channels
can be influenced by Dual Rate, Exponential and Throttle Curve
settings, they are included in the list twice - once where the
D/R and EXP settings are in effect and again where the D/R
and EXP settings are ignored. The second time they are listed,
there is a special designator to indicate that these channels can
also be used as a master while bypassing any Dual Rate and
Exponential settings that may be associated with them. They are
designated by a “#” (pound sign) in front of the name - #FLP,
#AIL, #ELE and #RUD. When one of these channels is selected
as the master, all D/R, EXP and Curve settings associated with
the master are ignored during the mixing operation. Instead, the
mixer reads only the physical position of the stick to perform
mixing.
A (+) behind the channel indicates a trim-include function. By
selecting a channel with the (+) the trim lever affects both the
master and slave channels.
Slave Channel
This is the slave channel that will move according to the
program mix in relation to the master channel.
The slave channel is selected by highlighting and selecting
this parameter to obtain a list of channels and then selecting
the slave channel from the list. The list contains each of the 12
channels in the system.
Point Names/Numbers
The points that can be adjusted are listed vertically by name and
are also displayed by number along the bottom of the graph.
Change the value of a point by highlighting and selecting the
point name and dialing-in the desired percentage.
Current Point Setting
This list shows the setting for each of the 8 adjustable points
(Point-L, 1, 2, 3, 4, 5, 6, 7, H). The value of each point
determines where the point is positioned vertically on the graph,
which dictates the slave servo position relative to the master.
The point values can be set from -100 to +100. A value of 0
indicates the slave’s center or neutral position. The overall travel
of the slave channel is affected by the Travel settings described
in the TRVL ADJ. function.
The value for a point can be changed by highlighting and
selecting the Point Name to the left of the point value and then
dialing-in the desired value.
Pressing the CLR button when a point value is highlighted
resets the point to original settings.
H-49
Vertical Line
The vertical line on the graph shows the current master channel
position. When the master channel is deflected fully in one
direction, the line is to the extreme left over Point-L. When it
is at neutral, it is in the center over Point-1 and when it is fully
deflected in the other direction, the cursor is at the extreme right
of the graph over Point-H. Where the vertical line intersects
the Curve/Line over a given point defines slave servo position,
which is equal to the value assigned to that point.
Multi-Point Programmable Mixer
Graph
The graph illustrates the mixing curve. The X-Axis (horizontal
plane) represents master channel movement. The Y-Axis
(vertical plane) represents the slave servo movement where the
bottom 1/2 of the graph is one direction from neutral and the
top portion of the graph is the other direction.
Points that Can Be Added and Adjusted
Note: To eliminate a point press ERAS (bottom left of the
screen) when the point is highlighted.
Curve mixes are defaulted to three points (L, 1 and H). Up to
five additional point can be added. To add a point, move the
master channel in the desired position until STOR appears on
the left bottom of the screen. Pressing STOR will store a new
point at that position.
Exponential
The Exponential function blends the curve between the points
on the graph to provide a smooth response. The default value is
OFF. To turn it on and smooth the mixing curve, highlight and
select OFF and it will toggle to ON.
Slave Channel Position
The slave servo position next to OUT at the bottom left of the
display is expressed in values from -100 to +100, with 0 being
neutral or center. It represents the servo travel that corresponds
to the present master channel position.
H-50
Master Channel Position
The master channel position is shown on the bottom line of the
display next to IN and is expressed in values from 0 to 100 with
50 being the center or neutral position. It represents the present
master channel position.
Switch Select
To select a switch that will switch between the Pos0 and Pos1
values, highlight and select the switch name and it will toggle
between Pos0 and Pos1.
There are numerous switches that can be used to switch
between the Pos0 and Pos1.
Note: If the upper and lower settings for Pos0 or Pos1
are left at 0%, the mixer can be turned on and off with
the switch. In addition, if Flight Modes are activated in
the Devic.SEL function, then flight mode switches may be
selected. Also Switch positions can be used to selected
between Pos0 and Pos1.
CLR Button
Pressing the CLR button while a modifiable parameter is
selected will reset the parameter to its default value.
Note: Pressing the CLR button when either the master or
slave is highlighted inhibits the entire mix.
LIST Button
Press the LIST button to return to the FUNCTION List, or rotate
the rotary selector until LST appears next to LIST and select it
to return to the SYSTEM Menu.
ENT Button
Pressing the ENT button returns to the Main Display.
To Inhibit a Mixer (Turn it off entirely)
Highlight either the master or slave and press the CLR button to
completely disable a mixer.
H-51
75: Monitor
The Monitor screen displays each channel and shows the
movement of channels when sticks, levers and switches are
moved. It renames channels according to special assignments
to assist in identifying each channel. For instance, when
Flaperon is the wing type, the Monitor will display RAIL for
right Aileron and LAIL for left Aileron instead of displaying
channel 2 and channel 6. The Monitor function also displays
the current value of all digital trims.
1. To access the Monitor function, highlight and select
MONITOR in the FUNC.LIST to obtain the Monitor display.
2. The default display shows the graphical positions of
all channels. To view the digital trim positions for all

wing type and snap roll functions. This screen is a convenient
way to determine which functions are activated.
1. To access the Mix Monitor screen, highlight and select MIX
MON in the FUNC.LIST to obtain the Mix Monitor display.
H-52
78: Trainer
The 12X features a programmable Trainer System that allows
the instructor to transfer some or all of the primary flight control
functions (Throttle, Aileron, Elevator and Rudder) to the student.
It also allows for indicating if the transmitter is to be the
master (controlled by the instructor) or slave (controlled by the
student). The right or left trim lever is used to transfer control to
the student when the 12X is being used as the master/instructor
transmitter.
All Dual and Expo rates, Gear and flap positions are controlled
by the master transmitter. Only the Throttle, Aileron, Elevator
and Rudder channels are transferred to the slave transmitter.
1. Connect the Trainer cord between the master and slave
transmitters. Turn the power on to the master transmitter
(the slave transmitter remains powered off and can even
have the module removed).
2. If the slave radio is a 72MHz system, make sure the slave
transmitter is in the PPM/FM modulation mode. If the slave
system is a 2.4GHz DSM, this does not apply.
Note: The Slave transmitter battery must be charged.
3. Highlight and select Trainer in the FUNC.LIST to obtain the
Trainer Display.
12X Used as Master (Instructor)
1. If the 12X is being used as the master transmitter (the

The 12X is now ready to be used as the slave or student
transmitter.
H-53
87: Timer
The 12X features a sophisticated timer system with three timers.
An integrated timer keeps track of total transmitter-on time for
the current selected model and integrated time is displayed
on the main display. Two other timers can be configured as
countdown timers or as a stopwatch. These timers also appear
on the main display when active and can be started and stopped
via various switches. In addition an interval function can be
programmed such that alarm will sound at preprogrammed
intervals. A down alarm can be programmed that will sound an
alarm prior and up to the programmed count down time and a
one time function sounds the alarm once or continuously when
the time is reached.

Programming a Sailplane
The following section contains in-depth details regarding each
of the available programming functions. If you’re just getting
started, you’ll likely find it easier (and we recommend) using
the Applications Guide included separately with your 12X
system. This step-by-step guide leads you through a typical
6-servo sailplane giving the key strokes necessary to set up a
sailplane, including flight modes, crow and side lever camber
adjustments. We recommend referring to the section below
when a more in-depth understanding of a specific programming
feature is desired.
System Mode
System mode contains the foundational programming that is
normally only used when first setting up a Sailplane. System
mode functions include: model select, model name, model
reset, Wing type etc.—functions that are typically set once
during setup and then are seldom changed or adjusted. Below
and throughout this section, the functions are in the order that
they appear in the System Mode List.
To Enter System Mode

S-11
83: Trim System
The Trim System function adjusts the sensitivity of the spoiler,
aileron, elevator and rudder trims, plus the Flap trim and
Flaperon trim levers. The aileron, elevator and rudder trims are
adjustable from 0–10, with 10 being the coarsest adjustment
and 0 being trim off. The Flap and Flaperon trims are adjustable
from 0 to 30 in 3-step increments. Adjusting the digital
trim values has no effect on the total trim travel (unless 0 is
selected), however, it affects the resolution of each trim input.
When the value is set to 10, each click of trim adjusts the servo
output by 10µs and there are only 10 trim increments from
center to each end. When set to 5, the output is changed 5us
per trim step and there are 20 trim increments from center to
each end. When set to 1, each click of trim changes the servo
output by 1µs and there are 100 trim increments. When set to 0
the trim levers cease to function effectively, turning off the trim
function. The right and left trim levers are adjustable from 0 to
200 and can be turned on/ off. When adjusted to above 100%
the trimmer functions as a three-position switch. Reducing the
value increases the number of output positions.
When adjusting the digital trims (AILE, ELEV, RUDD), the total
trim travel does not change – only the number of increments
(beeps) changes, which makes for finer or coarser trim
movements. When adjusting the analog spoiler trim, however,
the total trim travel is actually reduced when set to less than
100%.
It is recommended to use a fairly coarse setting, such as the
factory default 4, when test flying a model for the first flights in
order to be able to trim it quickly, and then use a finer setting,
such as 3–1, for final precision trimming.
LST Trim
The LST trim feature has two options, LST and normal. In
normal, when making trim changes using the Aileron elevator
or rudder digital trims, the center as well as each end point is
affected by the trim value (i.e. right trim causes the center, the
right end point and the left end point to all shift to the right).
When LST is activated, only the center position is trimmed.
(i.e. the center is shifted to the right but the end points are not
affected). This is useful for control surfaces that have a hard
stop end point to prevent over-travel caused by trim or if it’s
desired to have trim changes not affect the total roll pitch or yaw
rate. LST trim is normally turned off for sailplanes.
S-12
To Adjust the Trim Rates
1. Highlight and select TRIM SYS. in the SYSTEM menu to
acquire the Trim System function.
2. Highlight and select the trim that is to be changed and

S-19
Flight Modes
Most of the functions found in the 12X that are switch
selectable, including Flaperon Mix, Servo Speed, Camber
system, Differential, Aileron to rudder mix, Elevator to flap mix,
Flap rate, Brake system, trims and programmable mixes, can be
assigned to one or more Flight Modes. This provides the ability
to have up to 5 completely different aircraft configurations that
are selectable in flight using switches.
A Flight Mode represents an aircraft configuration (camber
position, trim positions, Dual Rate/Expo settings, program
mixes, aileron differential value, etc.) that is programmed to
optimize the aircraft for a particular task. Up to 5 flight modes
are available in the 12X that include Launch, Cruise, Speed,
Thermal and Land.
The objective of programming Flight Modes is to provide
the ability to select a switch position to activate a collection
of settings that are optimized to perform a particular task.
For example, the launch mode is typically set up to give the
following:
• The flaps and flaperons are preset with positive camber to
give more lift during launch.
• An elevator preset trim position that gives the best climb is
programmed.
• A high rudder rate with reduced exponential to give
authoritative steering control on launch is desired, while
the elevator and aileron rates are set to give a medium
response.
• Aileron-to-rudder mix is turned off, as are landing flaps and
elevator-to-flap mix while camber adjustment of the side
lever is programmed to give proportional camber changes
to allow for last minute adjustments based on wind and
winch conditions.
Five Flight Modes are available in the 12X system. When 3
Flight Modes are activated, they are selected during flight by
using one of seven 3-position switches (Flight mode switch,
Motor switch, Butterfly switch, Rudder D/R switch, Elevator D/R
switch, Aux 2 switch, Aileron D/R switch or Inhibit). To activate
the 2 Extra flight modes (5 flight modes in total), the 4th and
5th flight modes are assigned to one of the following switches
( Flight Mode, Rudder D/R switch, Elevator D/R switch, Flap
Switch, Aux 2 switch, Aileron D/R switch, Inhibit). Flight mode
switches are selected and activated in the Device SEL function
in the System menu. Once Flight Modes are activated, the pilot
has a choice of using the Flight Mode switch to select up to
5 Dual Rates and Exponential settings for each of the primary
controls (ELEV, AILE, RUDD), or Dual Rates and Exponential
settings may continue to be controlled by the 3 individual Dual
Rate switches. All other functions that can be activated by a
switch can be assigned to 1 or more Flight Modes when Flight
Modes have been activated.
• Aileron differential is set at 50%.
All these (and many more) programming parameters can be
selected by simply moving one switch. At the top of the launch
you prepare to zoom by switching to the cruise mode. A single
flip of the switch neutralizes the trailing edge while giving the
correct elevator trim for cruise. Rudder-to-elevator and elevatorto-flap mixes automatically turn on the programmed values
and the aileron differential is now at a much higher 75% for
more coordinated thermal turns. At the flip of a single switch
you’re ready for a zoom launch and for hunting thermals! And
remember there are 3 more flight modes available. Once you
start using flight modes, you’ll wonder how you ever flew
without them.
S-20
Activating and Assigning Primary Flight Modes
In the factory default setting, all flight modes are inhibited.
Flight modes are activated and assigned to the desired switch
position using the SPEED and LAUN functions in the Device

21: Flaperon Mix
Flaperon Mix Combines four mixes in one screen. Mixes
include Flap-to-Flaperon mix, Flap-to-Elevator mix, Aileron-toFlap mix, and Aileron-to-Tip aileron mix if the tip ailerons are
activated in the wing type function. The flap lever-offset position
is programmable allowing pilots to choose the neutral position.
The flap functions can be programmed to one of many different
levers or switches in the Device Select screen. The default is
the left lever. Mix values are based on a percentage of the flap
values so until a flap value is programmed in code 69. Flap

24: Servo Speed
The 12X provides the ability to adjust the speed of servos for
each channel in each direction. The speed may be reduced
(servo slowed) from its normal speed but it cannot cause a
servo to move faster than its rated specifications. Each servo
can have 2 sets of speeds in each direction that are Flight Mode
or switch selectable.
To Adjust Servo Speed
1. Highlight and select SRV. Speed. Speed FUNC.LIST.
2. If flight modes are not programmed, select SW SEL and
press the roller to access Switch Select. If only one servo
speed is desired, then all selectable switch positions in this
screen should be P0. If two servo speeds are desired, then
assign the desired switch that will change the servo speed
to P1. Return to the main screen.
3. If a single set of servo speeds is desired, make sure the
display is showing Pos0. If it is not, select Pos1 and
change it to Pos0. Highlight and select the channel and
direction for each servo that is to be adjusted. Once a
direction for a servo is selected, the servo speed may be set
so the servo travels from .193 seconds for 60 degrees of
rotation to 16.4 seconds for 60 degrees of rotation. Adjust
the speed of each servo until the desired speed is obtained.
4. If 2 sets of servo speeds are desired that are Flight Mode or
switch selectable, one set of values is set to NORM for all
channels; slowing of servos can be turned off by selecting
the position (Pos0 or Pos1) that has the NORM values.
Highlight and select Pos0 and change it to Pos1 and then
highlight and select the channel and direction for each
servo that is to be adjusted. Once a direction for a servo is
selected, the servo speed may be set so the servo travels at
the desired slower rate. Switch between Pos0 and Pos1 to
view and adjust the 2 sets of values for each servo.
Note: Pos1 always has priority over Pos0. In other words,
if multiple switches are selected and one of the switches
is in its Pos1 position, then all other switches are ignored
and the Pos1 values are in effect.
5. If flight modes are programmed, using the roller highlight
the flight mode then press the roller. Rotate the roller to
access the desired flight mode then select the servo speed
desired for that flight mode. Repeat for all flight modes.
S-28
25: Camber System
The Camber system allows preset camber adjustments for each
programmed flight mode for the right and left ailerons, the right
and left flaps, and if activated the right and left tip ailerons. The
camber system allows for adjustments to the preset camber
setting for each flight mode that is automatically selected with
each flight mode. A Delay function is available that causes
the smooth transition of the control surfaces from one flight
mode to the next plus a Break function is available that will
reduce the camber at a preset elevator stick position. Flap and
Flaperon trim steps are also adjustable in the Camber system.
Mix combines four mixes in one screen. Mixes include Flap-
to-Flaperon mix, Flap-to-Elevator mix, Aileron-to-Flap mix,
and Aileron-to-Tip aileron mix if the tip ailerons are activated
in the wing type function. The flap lever-offset position is
programmable allowing pilots to choose the neutral position.
The flap functions can be programmed to one of many different
levers or switches in the Device Select screen. The default is
the left lever. Mix values are based on a percentage of the flap
values, so until a flap value is programmed in code 69. Flap
rate the Flaperon Mix function will not operate.
To Access the Camber System
1. In FUNC.LIST rotate the Selector until CAMB SYS. is
highlighted. Press the Selector to access the Camber
System menu.
2. If you wish to program a Break point with elevator input
(reduces camber with elevator input), then highlight
Elevator STK and program the desired Elevator offset. This
value establishes the point at which the reduction of camber
will occur.
3. Rotate the Selector to highlight the desired value then press
the Selector to access this value. With the flight mode
switch in the corresponding mode, adjust the value to the
desired position for each control surface. Repeat this for all
desired flight modes and control surface positions.
4. If desired, a delay can be programmed that will smoothly
transition the control positions when changing from one
flight mode to the next. The adjust range is from INH to 6.0
seconds or hold.
5. Press the LIST button to return to the Function Mode
screen.
S-29
32: Differential
The Aileron Differential function provides for up to 5 Differential
and Brake Differential settings that are Flight Mode selectable.
When flight modes are activated in Device Select (see page
S-19), the differential screen displays an Aileron Differential
Value and Brake Diff. Value for each flight mode that will
automatically be selected via the flight mode switch.
The 12X Aileron Differential function reduces the travel of the
Aileron that deflects downward without affecting the Aileron
that travels upward, eliminating adverse yaw effects and
improving coordinated turns. The Brake Differential function
is programmable that reduces the aileron differential when
the crow/butterfly, spoiler stick is deployed; it is helpful for
maintaining aileron authority during spot landings.
To Use the Aileron Differential Function
1. Highlight and select AIL Diff. in the FUNC.LIST to obtain
the Aileron Differential display.
2. If no flight modes are activated, a single Aileron differential
and Brake Diff setting is available. Highlight the AILE
or Brake DIFF to program the desired values. A positive
differential value causes the downward Aileron to travel less
(normally used) while a negative value causes the upward
Aileron to travel less (negative differential). Brake Diff value
reduces the differential as the spoiler stick is deployed.
3. If Flight modes are activated (see Device Select page S-19),
Differential and Brake Diff values can be assigned for each
flight mode and are automatically activated via the flight
mode switch.
S-30
33: Balance
to linkage geometry inaccuracies. The Balance function allows
the servo output of the master servo to be adjusted at 7 points
throughout the range, compensating for any linkage geometry
inaccuracies. Think of Balance as a curve mix that allows the
master channels to be independently adjusted at seven different
points, allowing a perfect bind-free setup throughout the control
stroke.
The 12X features a Balance function that allows the servo
outputs of dual channels to be adjusted throughout the range.
This is useful when two servos are used to drive a single
surface (i.e. two aileron servos used to drive one aileron), and
the linkage geometry of each servo is slightly different (typical
with a tapered aileron). If both servos are mixed in a linear
fashion, binding will occur throughout the control range due
To Program the Balance Function
1. Highlight and select Balance in the FUNC.LIST to obtain the
Balance display.
2. Note that the Balance screen will display the functions that
are programmed in the Wing Type. If no dual functions
are programmed in Device Select, then only one aileron
column will appear in the balance screen. If dual flaps are
programmed then two columns will appear in the balance
screen. This also applies to the dual elevator and rudder
functions.
3. Using the roller, highlight the desired position and press
the roller to access the value. Rotate the roller to change
the output position that is selected. The range is +100 to
-100. Repeat this for all positions until no binding occurs
throughout Control Travel.
S-31
44: Gyro Sensor
The 12X features a Gyro Gain system that allows for the
individual in-flight selection of gain setting for each active flight
mode. To access the Gyro function, at least three flight modes
must be activated in Device Select and the Moto channel (CH
5) must be programmed to GYR in device select code 17 and
the gyro gain lead must be plugged into the Moto (channel 5)
receiver port.
To Access the Gyro Sensor
1. Highlight and select GYRO SENS. in the FUNC.LIST.
2. Use the Rolling Selector to select the gain position to
be adjusted, and then press and roll the Rolling Selector
to increase or decrease the gain values as needed. Gain
setting will automatically be selected via the flight mode
switch.
46: Rudder-to-Spoiler Mix
Note: Dual spoilers must be activated in Wing Type in
order to access the Rudder-to-Spoiler mix.
The Rudder-to-Spoiler mix causes the spoiler to move in unison
with rudder. This mix can be utilized to improve the turning/
handling characteristics, especially on landings. Rudder-toSpoiler mix values can be independently adjusted for each of
the 5 flight modes.
To Access Rudder-to-Spoiler Mix
in the corresponding mode, give a rudder command and
rotate the Selector to achieve the desired spoiler mix value.
Pressing the Selector will store the value.
1. In FUNC.LIST rotate the Selector until RUDDSPOI is

screen.
S-32
62: Aileron-to-Rudder Mix
Aileron-to-Rudder mix causes the rudder to move in unison
with the ailerons. It is utilized to reduce adverse yaw and to
improve the turning/ handling characteristics. Aileron-to-Rudder
mix values can be independently adjusted right and left for each
of the 5 flight modes.
To Access Aileron-to-Rudder Mix
4. In FUNC.LIST rotate the Selector until AILRUD M is
highlighted. Press the Selector to access the Aileron-toRudder mix menu.

corresponding to the flight mode and desired direction and
then press the Selector to access that value. With the flight
mode switch in the corresponding mode, give an aileron
command and rotate the Selector to achieve the desired
rudder value. Pressing the Selector will store the value.
7. Press the LIST button to return to the Function Mode
screen.
S-33
63: Elevator-to-Flap Mix
Elevator-to-Flap mix is normally used to give several degrees
of down flap when up elevator is applied. This gives more pitch
authority than would elevator alone, and is commonly used
for slope racers to improve high-speed turns and in thermal
sailplanes to allow increased maneuverability for tight thermal
turns. An offset is available that allows the programming of
snap-flaps. With snap-flaps, no flap mixing occurs during small
to medium up elevator inputs, but at about offset point of up
elevator, the flaps are mixed to give down flaps, causing greater
up pitch authority.
To Access Elevator-to-Flap Mix
1. In Function Mode list, rotate the Selector until ELEFLP M
is highlighted. Press the Selector to access the Elevator-toFlap mix menu.
2. Note that Elevator-to-Flap mix values are available for each
active flight mode and the Elevator-to-Flap values can be
independently adjusted up and down. Also the offset (the
stick position where the mixing changes from up to down)
can be adjusted. This offset allows the programming of
snap-flaps, a common sailplane function that gives greater
full up elevator pitch authority for tighter turns. If you
choose to program snap-flaps, the offset adjustment range
is -200 to +200. Negative values move the offset in the up
elevator direction. Switches are available at the bottom of
the screen that allow the selection of Pos0 or Pos1.
S-34
69: Flap Rate
The Flap Rate function adjusts the up and down flap travel when
using the Flap Lever (default) or which ever lever or switch is
selected to operate the flaps in Device Select Code 17. Each
flight mode that is activated in Device Select code 17. will be
displayed with a up and down value in the Flap Rate screen.
The adjustment range is +125% to-125%. Flap Rate is used in
conjunction with the Flaperon Mix function Code 21. to adjust
the desired camber setting ranges when using the flap levers for
each flight mode.
To Access the Flap Rate Function
1. In Function Mode list, rotate the Selector until FLAP Rate
is highlighted. Press the Selector to access the Flap Rate
function.
2. Rotate the selector to highlight the desired value next to the
intended flight mode and press the roller.
3. Rotate the roller to adjust the flap value.
Note: Flap values are available for each active flight mode
and the values can be independently adjusted up and
down.
S-35
71: Brake System
The Brake System is the landing program that mixes the
spoilers, flaperons, flaps, and tip ailerons (if equipped) and
elevator to the spoiler (throttle) stick. Two values are available,
Pos0 and Pos1; each can be assigned to several different
switches or flight modes. An offset is provided (SPOI Pos.) to
allow the user’s preference for the neutral position (normally
stick up).
To Access the Brake System
1. In FUNC.LIST rotate the Selector until Brake SYS is
highlighted. Press the Selector to access the Brake System.
Note: The default setting for Spoiler offset Position is
at +100%. With this setting, the flap’s neutral position
(trailing edge level) occurs when the spoiler stick is in
the full up position. If you choose to locate the neutral
position in the down position, the value would be –100%.
2. Rotate the Selector to highlight SW select and press the
Selector to access the available switches.
3. To access the various values, rotate the Selector to highlight
them then depress the Selector to access the value. Move
the spoiler stick to the full down position and adjust the
value by rotating the Selector until the desired position is
achieved. Press the Selector to store the value.
4. The BRAKEELEV mix allows up to 7 points to be stored
and programmed. Two positions are available. This system
allows several points on a curve to be adjusted for Flap-toElevator mixing.
5. Press the LIST button to return to the Function Mode
screen.
S-36
51 thru 58: Programmable Mixers
The primary channel is called the Master channel, while the
channel that reacts to the Master is called the Slave channel.
Programmable mixers are programmed to cause a second
or slave channel to react as a result of providing input to
the primary or master channel or to cause a channel to be
controlled by moving a switch or lever. Programmable mixes
are typically used to activate special aircraft functions like tow
hook releases, snap flaps, Flap-to-Elevator curve mix, and
mixes to correct for flight dynamics.
Mixes are fully programmable, allowing any of the 12 channels
to be Master, Slave or both (a channel can be mixed to itself).
Trimmers and levers can also be used as a master and are
extremely useful for programming a proportional channel to
be operated via a trimmer or lever. Additionally programmable
mixes can always be on, or turned off and on via a programmed
switch, stick position or flight mode. The Snap Roll/ Trainer, ?
switch (momentary switch SNPT) can also be programmed as
the Master channel.
The 12X provides 3 Standard programmable mixes (PROG.
MIX1 - PROG.MIX3) and 5 Multi-Point or Curve programmable
mixes (PROG.MIX4 - PROG.MIX8). Multi-Point (or Curve)
Mixing provides the ability to program a customized curve that
the Slave channel will follow as it reacts to the Master channel’s
input. Multi-Point mixes are different from Normal Mixes in
that Normal Mixing results in a linear movement of the Slave
channel in relation to the Master. With Multi-Point Mixing there
are up to 8 points that can be adjusted to control the position
of the Slave channel, providing the ability to custom tailor the
output of the slave channel.
Additionally There are Two Options for Master Channels
“#” (pound sign) – these Master channels are Origin-type
mixes. These include #THRO, #AIL, #ELE, and #RUD. Origin
mixing bypasses any other mixing that might affect that channel
such as throttle curves, exponential, travel adjust or other
programming and uses the stick position only to control the
mix.
“+” (plus sign) – these Master channels are trim-include
type-mixes. These include THR+, ELE+, AIL+, and RUD+. Trim
Include mixes include the trim of the Master channel as well
as any other mixing to the Master channel to control the Slave
channel of the mix.
Standard Programmable Mixer - (Std. Prog Mixer)
The 12X has 3 standard programmable mixers that allow for
linear mixing of a Master channel to a Slave channel. The
standard mixers are PROG.Mix1, Mix 2 and Mix 3.
These mixes provide for 2 sets of mixing values named Pos0
and Pos1. If one set of values is set to 0% then the mixer can
be turned On and Off with a stick, switch or lever. Each set of
mixing values is comprised of 2 percentages to accommodate
movement of the Master channel in both directions. This is
shown in the illustration below where there is an upper and
lower percentage for both Pos0 and Pos1.
A mix can be made to always be on by setting Pos0 values only
and not selecting any switches to switch between the Pos0 and
Pos1 values.
S-37
Master Channel - (Std. Prog Mixer)
The Master channel is the primary or controlling channel. The
default for both the Master and the Slave channel is THRO. The
Master channel is selected by highlighting and selecting this
parameter to obtain a list of channels and then selecting the
Master channel from the list.
Note: There are 4 channels that appear more than once.
They are Throttle, Aileron, Elevator and Rudder. Since
these channels can be influenced by Dual Rate and
Exponential settings, they are included in the list twice
- once where the D/R and EXP settings are in effect and
again where the D/R and EXP settings are ignored. The
second time they are listed, there is a special designator to
indicate that these channels can also be used as a Master
while bypassing any Dual Rate and Exponential settings
that may be associated with them. They are designated
by a # (pound sign) in front of the name - #THRO, #AILE,
#ELE, and #RUD. When one of these channels is selected
as the Master, all D/R, EXP and Curve settings associated
with the Master are ignored during the mixing operation.
Instead, the mixer reads only the physical position of the
stick to perform mixing.
A (+) behind the channel indicates a trim include function. By
selecting a channel with the (+) the trim lever affects both the
Master and Slave channels.
S-38
Note: Some programmable mixes have + appearing after
a specific channel and other mixes have a # before that
specific channel. Choose the programmable mix that offers
the type of mix (origin of trim include) that you desire.
Slave Channel - (Std. Prog Mixer)
The Slave channel is the secondary receiving channel and will
move according to the program mix in relation to the Master
channel. The default for both the Master and the Slave channel
is THRO.
The Slave channel is selected by highlighting and selecting
this parameter to obtain a list of channels and then selecting
the Slave channel from the list. The list contains each of the 12
channels in the system and CANCEL.
Switch Position
standard programmable mixer has two positions - Pos0 and
Pos1 and each position has 2 percentages (upper and lower)
to accommodate mixing when the Master is moved in both
directions. Note that POS 1 has priority over POS 0.
The right side of the Programmable mix screen displays the
available switch options. If you choose to have a switch control
the mix, either on/off or have two mix values, highlight and
select the desired switch(s) and select position 0 or 1. Each
Offset
Offset defines the position where the mixer changes directions.
The Offset is defaulted to center position or 0 and this is most
commonly used. With a 0 Offset, if the Rudder is the Master,
moving the rudder stick to the left of center causes a mix in one
direction while moving the rudder stick to the right of center
causes a mix in the other direction. Directions correspond to the
upper and lower percentages for Pos0 and the upper and lower
percentages of Pos1. The amount of mix and actual direction
that the Slave moves is determined by the Pos0/Pos1 values.
The Offset applies to both Pos0 and Pos1 settings.
The Offset may be changed by highlighting and selecting
Offset and adjusting either a positive (+) or negative (-) value.
A positive percentage moves the Offset in one direction from
center while a negative percentage moves the Offset in the other
direction from center.
S-39
Mix Values
Each standard Programmable mixer can have two sets of mixing
values - Pos0 and Pos1. Each set can have 2 percentages which
control movement of the Slave when the Master is moved in
each direction. A switch can be selected to switch between the
Pos0 and Pos1 percentages.
The Pos0 settings determine how far, and in which direction,
the slave channel moves when the Master is moved above and
below the Offset (the Master moving in both directions) when
the switch is in a position to select the Pos0 values.
To enter Pos0 values, highlight and select Pos0, move the
Master channel control (stick, lever or switch) in one direction
and set the percentage and then move the Master channel
control in the other direction and set its value.
The Pos1 settings are identical to the Pos0 settings and
determine how far, and in which direction, the Slave channel
moves when the Master is moved above and below the offset
(the Master moving in both directions) when the switch is in a
position to select the Pos1 values.
To enter Pos1 values, highlight and select Pos1, move the
Master channel control (stick, lever or switch) in one direction
and set the percentage and then move the Master channel
control in the other direction and set its value.
CLR Button - (Std. Prog Mixer)
Note: Pressing the CLR button while a modifiable
parameter is selected will reset the parameter to its default
value. Pressing the CLR button when either the Master or
Slave is highlighted inhibits the entire mixer and it is no
longer functional.
To Inhibit a Mix
Highlight either the Master or Slave and press the CLR button
to completely disable a mixer.
S-40
Multi-Point Programmable Mixer
There are 5 Multi-Point Programmable Mixers in the 12x, Prog.
Mix4 through Prog.Mix8. They differ from the standard mixes in
that they allow non-linear mix response from the Master to the
Slave. This is possible because the mixer uses up to 8 points
to define the position of the Slave channel relative to the Master
channel at up to 8 selectable points. As the Master reaches each
point, the Slave response position can be defined independent
of other point settings.
Master Channel
The Master channel is the primary channel, lever or trim lever.
The Master channel is selected by highlighting and selecting
this parameter to obtain a list of channels and then selecting the
Master channel from the list.
There are 4 channels that appear more than once. They are
Throttle, Aileron, Elevator and Rudder. Since these channels
can be influenced by Dual Rate, Exponential, and Throttle Curve
settings, they are included in the list twice – once where the
D/R and EXP settings are in effect and again where the D/R
and EXP settings are ignored. The second time they are listed,
there is a special designator to indicate that these channels can
also be used as a Master while bypassing any Dual Rate and
Exponential settings that may be associated with them. They
are designated by a # (pound sign) in front of the name - #FLP,
#AIL, #ELE, and #RUD. When one of these channels is selected
as the Master, all D/R, EXP and Curve settings associated with
the Master are ignored during the mixing operation. Instead, the
mixer reads only the physical position of the stick to perform
mixing.
A (+) behind the channel indicates a trim include function. By
selecting a channel with the (+) the trim lever affects both the
master and slave channels.
Slave Channel
The Slave channel is selected by highlighting and selecting
this parameter to obtain a list of channels and then selecting
the Slave channel from the list. The list contains each of the 12
channels in the system.
This is the Slave channel that will move according to the
program mix in relation to the Master channel.
Point Names/Numbers
The points that can be adjusted are listed vertically by name and
are also displayed by number along the bottom of the graph.
Change the value of a point by highlighting and selecting the
point name and dialing-in the desired percentage.
S-41
Current Point Setting
This list shows the setting for each of the 8 adjustable points
(Point-L, 1, 2, 3, 4, 5, 6, 7, H). The value of each point
determines where the point is positioned vertically on the graph,
which dictates the Slave servo position relative to the Master.
The point values can be set from -100 to +100. A value of 0
indicates the Slave’s center or neutral position. The overall
travel of the Slave channel is affected by the Travel settings
described in the TRVL ADJ. function.
The value for a point can be changed by highlighting and
selecting the Point Name to the left of the point value and then
dialing-in the desired value.
Pressing the CLR button when a point value is highlighted
resets the point to original settings. The original settings are:
Vertical Line
The Vertical line on the graph shows the current Master channel
position. When the Master channel is deflected fully in one
direction, the line is to the extreme left over Point-L; when it
is at neutral, it is in the center over Point-1; when it is fully
deflected in the other direction, the cursor is at the extreme right
of the graph over Point-H. Where the Vertical Line intersects
the Curve Line over a given point defines Slave servo position,
which is equal to the value assigned to that point.
Multi-Point Programmable Mixer
Graph
The graph illustrates the mixing curve. The X-Axis (horizontal
plane) represents Master channel movement. The Y-Axis
(vertical plane) represents the Slave servo movement, where the

78: Trainer
The 12X features a programmable Trainer System that allows
the instructor to transfer some or all of the primary flight control
functions (Throttle, Aileron, Elevator and Rudder) to the student.
It also allows for indicating if the transmitter (Tx) is to be the
Master (controlled by the instructor) or Slave (controlled by the
student). The right or left trim lever is used to transfer control to
the student when the 12X is being used as the Master/Instructor
transmitter.
All Dual and Expo rates, Gear, and flap positions are controlled
by the Master Tx. Only the Throttle, Aileron, Elevator and
Rudder channels are transferred to the Slave Tx.
1. Connect the Trainer cord between the Master and Slave
transmitters. Turn the power on to the Master transmitter
(the Slave Tx remains powered off and can even have the
module removed).
2. If the slave radio is a 72MHz system, make sure the Slave
Tx is in the PPM/FM modulation mode. If the Slave system
is a 2.4 DSM, this does not apply.
Note: The Slave Tx battery must be charged.
3. Highlight and select Trainer in the FUNC.LIST to obtain the
Trainer Display.
12X Used as Master (Instructor)
1. If the 12X is being used as the Master Tx (the Tx operated

Highlight and select MASTER and the display will switch
to SLAVE. A message will appear instructing to Connect
DSC & POWER off. Make sure the Tx power switch is in the
Off position and the DSC cord is connected between the 2
transmitters.
The 12X is now ready to be used as the Slave or student Tx.
S-45
87: Timer
The 12X features a sophisticated Timer System with three
timers. An integrated timer keeps track of total Tx-on time for
the current selected model and integrated time is displayed
on the Main display. Two other timers can be configured as
Countdown timers or as a Stopwatch. These timers also appear
on the Main display when active and can be started and stopped
via various switches. In addition, an interval function can be
programmed such that alarm will sound at preprogrammed
intervals. A Down Alarm can be programmed that will sound an
alarm prior and up to the programmed countdown time and a
one-time function sounds the alarm once or continuously when
the time is reached.
1. To configure the timers, highlight and select Timer in the
FUNCTION LIST to obtain the Timer display.
Highlight and select INH under TIMER1 or TIMER2 and
then select DOWN-T of STOP W. Use the Selector to set
the countdown set time, interval, down alarm and one-time
functions. Once the timer is set, TIM will appear on the Main
display in the lower left corner. The timers can be programmed
to several different buttons or switches. Use the Selector to
highlight the desired button or switch to operate the timer. Press
the Selector to confirm the selection. The desired set time, beep
interval, down alarm can be set as desired. When the One-Time
function is ON, the timer will start with the switch selected, but
pressing the switch again will have no effect. If the One-Time
function is OFF, the timer can be stopped, and restarted as
many times as desired with the switch selected.
2. To Reset the Integrated Timer, highlight and select the
time under INTEG-T and Push [CLR]=0:00 appears on the
display. Press the CLR button to the left of the display to
reset the integrated timer.
3. To reset the Stop Watch or Countdown Timer, highlight the
timer function using the roller on the screen and press CLR.

General Information
FCC Information
Servo Precautions
• Do not lubricate servo gears or motors.
This device complies with part 15 of the FCC rules. Operation
is subject to the following two conditions: (1) This device may
not cause harmful interference, and (2) this device must accept
any interference received, including interference that may cause
undesired operation.
• Do not overload retract servos during retracted or extended
conditions.Make sure they are able to travel their full
deflection. Overloading or stalling a servo can cause
excessive current drain.
• Make sure all servos move freely through their rotations
and no linkages hang up or bind. A binding control linkage
can cause a servo to draw excessive current. A stalled servo
can drain a battery pack in a matter of minutes.
Caution: Changes or modifications not expressly
approved by the party responsible for compliance could
void the user’s authority to operate the equipment.
• Correct any control surface “buzz” or “flutter” as soon as
it is noticed in flight, as this condition can destroy the
feedback potentiometer in the servo. It may be extremely
dangerous to ignore such “buzz” or “flutter.”
This product contains a radio transmitter with wireless
technology which has been tested and found to
be compliant with the applicable regulations governing a radio
transmitter in the 2.400GHz to 2.4835GHz frequency range.
• Use the supplied rubber grommets and brass servo eyelets
when mounting your servos. Do not over-tighten the servo
mounting screws, as this negates the dampening effect of
the rubber grommets.
Daily Flight Checks
1. Check the battery voltage on both the transmitter and
the receiver battery packs. Do not fly below 9.0V on the
transmitter or below 4.7V on the receiver. To do so can
crash your aircraft.
• Ensure the servo horn is securely fastened to the servo. Use
only the servo arm screws provided; the size is different
from other manufacturers.
Note: When you check these batteries, ensure that
you have the polarities correct on your expanded scale
voltmeter.
2. Check all hardware (linkages, screws, nuts, and bolts) prior
to each day’s flight. Be sure that binding does not occur and
that all parts are properly secured.
3. Ensure that all surfaces are moving in the proper manner.
4. Perform a ground range check before each day’s flying
session.
5. Prior to starting your aircraft, turn off your transmitter, then
turn it back on. Do this each time you start your aircraft.
If any critical switches are on without your knowledge, the
transmitter alarm will warn you at this time.
6. Check that all trim levers are in the proper location.
7. All servo pigtails and switch harness plugs should be
secured in the receiver. Make sure that the switch harness
moves freely in both directions.
• Discontinue to use servo arms when they become
“yellowed” or discolored. Such servo arms may be brittle
and can snap at any time, possibly causing the aircraft to
crash.
• Check all related mounting screws and linkages frequently.
Aircraft often vibrate, causing linkages and screws to
loosen.
General Notes
Radio controlled models are a great source of pleasure.
Unfortunately, they can also pose a potential hazard if not
operated and maintained properly.
It is imperative to install your radio control system correctly.
Additionally, your level of piloting competency must be high
enough to ensure that you are able to control your aircraft under
all conditions. If you are a newcomer to radio controlled flying,
please seek help from an experienced pilot or your local hobby
store.
W-1
Safety Do’s and Don’ts for Pilots
• Ensure that your batteries have been properly charged prior
to your initial flight.
• Keep track of the time the system is turned on so you will
know how long you can safely operate your system.
• Perform a ground range check prior to the initial flight
of the day. See the “Daily Flight Checks Section” for
information.
• Check all control surfaces prior to each takeoff.
• Do not fly your model near spectators, parking areas or any
other area that could result in injury to people or damage of
property.
• Do not fly during adverse weather conditions. Poor visibility
can cause disorientation and loss of control of your aircraft.
Strong winds can cause similar problems.
• Do not point the transmitter antenna directly toward the
model. The radiation pattern from the tip of the antenna is
inherently low.
• Do not take chances. If at any time during flight you
observe any erratic or abnormal operation, land immediately
and do not resume flight until the cause of the problem has
been ascertained and corrected. Safety can never be taken
lightly.
Federal Aviation Administration
Purpose
c. Do not fly higher than 400 feet above the surface.
This advisory outlines safety standards for operations of
model aircraft. We encourage voluntary compliance with these
standards.
d. Always operate more than three miles from the boundary of
an airport unless you are given permission to be closer by
the appropriate air traffic control facility in the case of an
airport for which a control zone has been designated or by
the airport manager in the case of other airports.
Background
Attention has been drawn to the increase in model aircraft
operation. There is a need for added caution when operating
free flight and radio controlled craft in order to avoid creating
a noise nuisance or a potential hazard to full-scale aircraft and
persons and/or property on the surface.
Operating Standards
Modelers generally are concerned with safety and exercise good
judgment when flying model aircraft. However, in the interest of
safer skies, we encourage operators of radio controlled and free
flight models to comply with the following standards:
a. Exercise vigilance in locating full-scale aircraft (get help if
possible) so as not to create a
collision hazard.
e. Do not hesitate to ask for assistance in complying with
these guidelines at the airport traffic control tower or air
route traffic control center nearest the site of your proposed
operation.
