JR 11X Transmitter and
Receiver Specifications
and Features
model’s memory (1 through 30) the transmitter is currently programmed to.
Later, if you select the incorrect model memory in the transmitter and turn the
receiver on, the model won’t operate. This prevents a possible crash. Change the
programming to the correct model memory, and you can fly.
With Spektrum’s 2.4GHz DSM technology, the JR 11X offers a hassle-free,
interference-free superior RF link for your airplane, helicopter or sailplane.
The same technology also significantly reduces latency so you have a more
responsive, precise connection to your aircraft. All of this means you can fly with
confidence and safety when you fly with the 11X.
The 11X features Advanced digital trims. On the Normal display screen, if you
move a trim lever, the screen automatically displays the graphic position for the
trim being adjusted. The 11X Aileron, Elevator and Rudder trim levers and the
right and left rear levers feature an audible center trim beep. This helps when
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 on the three front
digital trims. This allows you to be aware of the general trim position audibly
without looking at the transmitter.

receivers in park flyer-type aircraft (small electric airplanes or mini and micro
helicopters). Flying receivers designed for park flyers in larger aircraft could
cause a loss of control resulting in damage to property and/or injury.
Charging
Do’s and Don’ts
• Charge transmitter and receiver battery before flying.
• Check receiver battery charge between each flight using a tester with built-in
load.
• Only use charger on JR equipment. Charge plug polarity may be different.
Equipment damage can result.
• Do not use other manufacturer’s after-market accessories that plug into
JR 11X • RADIO INSTRUCTION MANUAL
transmitter charging jack. If you doubt polarity compatibility, seek expert
advice to avoid possible damage.
•The center pin on all JR transmitters is negative. Therefore, all JR chargers
have a negative center pin, not positive.
•Beware of improper connections based on color-coded wire leads—they
may not apply.
•ALWAYS connect the center pin of y our JR transmitter to the negative pole
for correct polarity.
Instructions
1.Plug the charger into the 11X battery port on the right side of the radio.
2.Plug the charger power supply into the wall outlet.
CAUTION: Not following proper sequence of numbers 1 and 2 can cause a
static short, which could damage the battery circuitry.
3.For initial charge and any charging of fully discharged battery, charge time
is 10–12 hours. Charge time decreases if battery is not fully discharged.
4.Monitor the temperature of battery during charging.
5.After charging, check the voltage of the battery pack by turning system on.
Voltage should be just over 11 volts (11.4 approximately but will vary).
6.During first use, battery voltage may drop below 9.6 volts. Charge the
battery again to just over 11 volts. Do not overcharge.
Notes
•The 11X battery contains a heat detector. If it senses excessive heat, it shuts
off the charger and shows an error on the charger LED.
•The battery voltage does not affect the output of the system as the output is
regulated internally.
•The 11X charger is not a peak detect charger. If using a fast charger for
the transmitter battery, do not exceed 1.5 amps (1500mA) charge rate or
damage to transmitter or battery can occur.
•The 11X charger output is DC 11.6V, with 110mA as the average charge rate.
•If using a peak detection charger, make sure battery is fully charged. NiMH
batteries tend to repeatedly false peak with peak detection fast chargers. Use
a charger that displays the total charge current. Note the number of mAh put
into a discharged pack to verify it charges to capacity.
Safety Precautions and Warnings
Failure to exercise caution while using this product and comply with the
following warnings could result in product malfunction, electrical issues,
excessive heat, FIRE, and ultimately injury and property damage.
•If the transmitter voltage drops below 9.0 volts or the battery alarm goes off
during flight, land immediately and recharge.
•Read all safety precautions and literature prior to use of this product.
•Never leave battery and charger unattended during use.
•Never allow minors to charge battery packs without adult supervision.
•Never attempt to charge dead or damaged batteries.
•Never charge a battery if the cable has been pinched or shorted.

time.
•Never charge batteries in extremely hot or cold places (recommended
between 50–80 drees Fahrenheit) or place in direct sunlight.
•Always use only compatible NiMH rechargeable batteries. This charger
cannot charge batteries such as “heavy duty,” “alkaline battery,” or
“mercury battery.”
•Always properly connect charger and battery.
•Always disconnect the battery and hcarger after charging, and let them cool
between charges.
•Always inspect the battery before charging.
•Always terminate all processes and contact Horizon Hobby if the product
malfunctions.

The JR R921 Receiver
The JR R921 incorporates two internal receivers and one remote receiver with
an optional second remote receiver. You must plug 1 remote receiver into one of
the remote receiver ports for the system to operate and a second remote receiver
(optional) into the remaining remote antenna port.
Installing the receivers in different locations throughout the aircraft exposes
each receiver to its own RF environment. This greatly improves the ability of
the receivers to see the signal in all conditions. This gives a solid RF link, even
in aircraft that have substantial conductive materials (e.g., turbine engines with
metal tail pipes, carbon fiber, tuned pipes, etc.) that can weaken the signal.
Installing the R921
Install the main receiver using the same method of a conventional receiver in
your aircraft. Typically, wrap the main receiver in protective foam and fasten it in
place using rubber bands or hook and loop straps. Alternately in electric models
or in jets (low vibration),you can use thick double-sided foam tape to fasten the
main receiver in place.
Using double-sided foam tape (servo tape), mount the remote receiver(s)
keeping it at least 2 inches away from the primary receiver. Ideally, you should
position the antennas perpendicular to each other. 6-, 9-, 12-, 24-, and 36-inch
leads are available. A standard installation includes the main receiver mounted
conventionally in the fuselage and the remote antennas in the nose (jets) in
the top turtle deck and even in the tail. The optimum location, especially for
sophisticated aircraft, is as far away from any conductive materials as practical.
In helicopters, the servo tray generally has enough room to achieve the
necessary separation. When needed you can make a mount using clear plastic to
position the remote receiver.
Other important installation tips:
1. Mount the servos using rubber grommets and brass eyelets to isolate them
from vibration. Do not over-tighten the mounting screws; this will negate
the vibration absorption effect of the rubber grommets. When mounting,
push the brass eyelets from the bottom up in the rubber grommets. By
tightening the servo screw securely, you provide the proper security and
vibration isolation for your servo.
2.The servo arms must be able to move freely over their entire range of travel.
Make sure 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 over its full travel.

Binding
Failsafe Functions
Binding is necessary to program the receiver to the transmitter so the receiver
only recognizes 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 JR R921. All JR
and Spektrum DSM aircraft receivers are bound in the same way.
The JR R921 receiver features two types of failsafe programming: SmartSafe and
Preset Failsafe.
How to Bind
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 port
and proceed to Step #2.
R92
1
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 bind mode through the switch. Plug the switch into the bind port
SmartSafe
SmartSafe is automatically selected during the standard binding procedure and is
ideal for electric aircraft as well as most gas- and glow-powered aircraft.
How SmartSafe Works
• When the Receiver is Powered On without a Transmitter Signal
If you turn on the R291 before you turn on the transmitter, SmartSafe
prevents the throttle from functioning and drives all other channels to their
preset positions.
• When there is a Loss of Signal in Flight
If the receiver loses the transmitter’s signal in flight, or any other time after
a successful connection has been made, SmartSafe sets the throttle to the
position it was in during the binding process. All other channels hold the
positions they were in at signal loss.
How to Program the Receiver for SmartSafe
Simply move the throttle to a desired in-flight failsafe position (typically this is
all the way back) and bind the receiver to the transmitter. Leave the bind plug in
the receiver during the entire binding process. Remove the bind plug only after a
connection has been made and the controls are functioning normally.
Preset Failsafe
Preset Failsafe allows you to set the specific control positions for all channels
to go to should you encounter signal loss in flight or at any other time after a
successful connection has been made. Preset Failsafe is typically used to prevent
“fly aways” in high-performance models by deploying spoilers in sailplanes or
putting gas- and glow-powered models into a slight turn at reduced throttle.
of the receiver. If a 3-wire switch is not available, install the male bind plug
directly into the receiver bind receptacle and power the receiver through any
other open port to enter bind mode.
2. Power on the receiver. The LEDs on all receivers should be flashing,
indicating the receiver is ready to bind.
3. Establish the desired failsafe stick positions: normally low throttle and flight
controls neutral.
How to Program Preset Failsafe Settings
Insert the bind plug and power on the receiver. When the receiver’s LED lights
begin to blink indicating it is in bind mode, remove the bind plug before binding
the transmitter to the receiver. The LED lights on the receiver continue to blink.
Move your transmitter’s control sticks and switches to the desired Preset Failsafe
positions then turn it on in bind mode. The system should connect in less than
15 seconds.
Range Testing
The Standard Range Testing procedure is recommended for most sport aircraft.
4. Press and hold the bind button on the back of the transmitter while turning
on the power switch. The bind lights on the front and rear of the transmitter
should flash and within a few seconds the system should connect. The LEDs
on the receivers should go solid, indicating the system has connected.
5. Remove the bind plug from the receiver or switch harness and store in a
convenient place.
6. After programming your model, rebind the system so the true low throttle
and neutral control surface positions are programmed.
7. When the transmitter is turned on and operating with the system, the amber
light on the rear of the transmitter will be on solid. The blue light on the
top front of the transmitter will also be on solid indicating the system is
outputting signal and operating.
6
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 Product Support at 1-877-504-0233 for further
assistance.
Receiver Power System
Requirements
The onboard power system must provide adequate power without interruption
to the receiver even when the servos are at maximum flight loads. Inadequate
power systems that do not provide the necessary minimum voltage to the receiver
during flight loads are the number one cause of in-flight failures. Some 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, and if used, the regulator and
power bus.
Recommended Power System Guidelines
1. When setting up large or complex aircraft with multiple high-torque servos,
you should use a current and voltmeter (HAN172). 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). Monitor the voltage at the receiver.
The voltage should remain above 4.8 volts even when all servos are heavily
loaded. The optional Flight Log has a built-in voltmeter and can be used.
2. With the current meter in line with the receiver battery lead, load the
control surfaces while monitoring the current. The maximum continuous
recommended current for a single heavy-duty servo/battery lead is three
amps. Short duration current spikes of up to five amps are acceptable.
If your system draws more than these currents, you should use multiple
packs with multiple switches and multiple leads plugged into the receiver.
While a JR receiver’s minimum operational voltage is 3.5 volts, you should
test the system to a minimum acceptable voltage of 4.8 volts during ground
testing. This provides headroom to compensate for battery discharging or if
the actual flight loads are greater than the ground test loads.
Note: JR’s amplified Y-harness (JRPA133) is for use with Z-PCM only. JR’s
non- amplified Y-harness (JRPA135) should be used with PPM, SPCM or
DSM/DSM2 systems.
3. If using a regulator, perform the above tests for an extended period of 5
minutes. When current passes through a regulator, heat is generated. This
causes the regulator to increase resistance, causing even more heat to build
up (thermal runaway). While a regulator may provide adequate power for a
short duration, you should test its ability over time. The regulator may not be
able to maintain voltage at significant power levels.
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 system you choose, always carry out
test #1 above. Make sure the receiver is constantly provided with 4.8 volts or
more under all conditions.

A Flight Mode represents an aircraft configuration (Dual Rate/ Expo, program
mixes, Aileron Differential, Flap System, Gyro System, etc.) that allows you to do
different things by flipping a single switch. Up to 3 flight modes are available in
the 11X.
Most of the functions found in the 11X 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 allows up to 3 completely
different aircraft configurations selectable in-flight 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).
You can select and activate Flight Mode switches in the Device SEL function in
the System menu. Once Flight Modes are activated, you have a choice of using
the Flight Mode switch to select up to 4 Dual Rates and Exponential settings
for each of the primary controls (ELEV, AILE, RUDD), or you can control Dual

JR 11X • RADIO INSTRUCTION MANUAL
Activate/Inhibit Channels
The 11X allows you the ability to activate, inhibit or program channels 5 (Gear), 7
(Aux2) and 8 (AUX 3) to operate as a 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 Elevator
and Rudder sticks operate the auxiliary channels. You should inhibit the auxiliary
switches in the Device Select function.
Note: If any of the channels identified above as a 2nd channel for a primary flight
control (AILE, ELEV, RUDD, FLAP), 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.
1. If using GEAR, FLAP, AUX2, AUX3, AUX4, AUX5 or AUX6 as a 2nd primary
flight control, inhibit the corresponding switch by highlighting ACT along
the right side of the display. Press the roller to select INH.
Note: When SYS appears next to FLAP, the FLAP SYSTEM function will appear
in the Function 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.
Note: When GYR appears, the Gyro Function appears in the Function List
(described later on page 27). Two gyro programs are available.
Note: When PIT appears, the Pitch Function appears in the Function List
(described later on page 22, 26).
15
Wing Type
Flaperon- If using two channels 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.
Twin Engine
The Wing Type function provides for 4 different wing types (NORMAL,
FLAPERON, DELTA and 4- Aileron). Use NORMAL wing type when using only
the Aileron channel to control ailerons, either with 1 servo, or multiple servos
connected through a Y-harness to the aileron channel.
Use FLAPERON typically when each Aileron is controlled by a separate servo
on separate channels and the aircraft has no other flaps. Setting the wing type to
FLAPERON also makes the Differential and Elevator-to-Flap mixing functions in
the Function List available.
Note: If using the ailerons as flaps, inhibit the FLAP Switch and FLAP TRIM in
the Devic.SEL function in the SYSTEM Menu. This eliminates having a severe
out-of-trim condition if the FLAP Switch is accidentally moved.
If the aircraft is equipped with twin engines, you can use the Twin Engine feature
(Twin E.) for a second throttle channel with an optional separate digital trim.
The Wing Type function contains the Twin Engine (Twin E.) feature, allowing
you to set up a 2nd throttle channel for a second engine, complete with its own
independent sub- trim, travel adjust and separate trims and throttle curves.
Use DELTA for Delta wing aircraft (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 operate the right aileron and two
servos operate the left aileron. In this configuration each servo is independently
adjustable for sub-trim and travel adjust.
Note: Dual ailerons is a function commonly employed for aircraft using two
servos and two channels to operate the Ailerons. It provides the ability to utilize
Aileron Differential and allow precise independent adjustment of sub-trim and
travel adjust for each aileron.
If the aircraft has flaps separate from the Ailerons, Dual aileron wing type and the
activation of dual flaps is recommended.
DELTA- If you have a Delta wing aircraft then select DELTA in wing type. This
mixes 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, select the 4- Aileron option. Right aileron servos
plug into channels 2 and 7. The left aileron servos plug into channels 5 and 8.
Each servo is independently adjustable for sub-trim and travel adjustment and the
digital trim is active for all servos.
If the aircraft 0has 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
Dual Control Functions
Wing Type allows you to activate Dual Aileron, Dual Elevator, Dual Rudder and
Dual Flap. Use this function when two servos are driving the primary control
surfaces allowing the independent adjustment of sub-trim and travel adjust of
each channel.
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 25).
To Program a Wing Type
1. Highlight and select Wing Type in the System List using the roller.
2. Highlight Wing then select the wing type appropriate for your aircraft.
The 11X provides the ability to change the standard default switch assignments
for the GEAR, AUX2 through AUX6 channels and the high pitch trim. The switch
positions are defaulted to the most common positions, however, changing the
switch assignments (positions) is a matter of preference.
To Change One or More Switch Assignments 1 In the Device Select function, use the Roller to highlight and select GEAR,
AUX2 through AUX6 channels.
2 Once a channel is selected, a list of available replacement switches is
displayed. Highlight and select the desired switch with the Roller.
3 In this selection screen, you can also set the 2 top trimmers to work as
2-position switches, 3-position switches, or as momentary switches for a
selected channel.
4 Repeat for as many switches as desired.
The 11X allows you to assign flight modes to any three-position switch. The
system defaults with the flight mode on the flight mode switch (upper left corner
of transmitter). In most cases this position is recommended.
V-Tail Mix
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.
Flight Modes (HELIcopter)
Switch Assignments
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. A list of available channels displays.
2 Highlight and select the channel to be the Slave to the control channel
represented above it. Plug the 2nd control surface servo into the channel
selected as the Slave.
3 INH appears on the Trim Line of the display directly beneath the channel
just selected. This means the corresponding digital trim (FLAP TRIM or
AUX TRIM) located next to the FLAP and AUX2 switches can be used as
additional trims.
However, additional trims do not function in the same fashion as regular trims.
Instead, they trim the controls so 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) becomes active. If set
to INH these additional trim switches are inactive. Normal trims continue to work
regardless of the settings.
To Assign the Flight Mode to a Switch
1 In Device Select highlight and select FMOD. A screen appears that allows
you to move the Flight Mode to the Rudder Dual Rate Switch, Ail D/R, ElE
D/R, Aux 2, Flap SW or the Flight Mode switch.
2 Using the roller, select the desired flight mode switch position. Alternately,
when you have the flight mode switch options displayed, move the switch
you would like to use as the flight mode switch. The system automatically
sets that switch to be the flight mode switch.

you can activate through the Device Select function.
To Activate 2 Additional Flight Modes (Flight Modes 3 and 4)
1 In the System List highlight and select Device Select.
2 Highlight and select INH under the word EXTRA using the Roller. When
selected, a screen appears allowing the various switch options. Highlight
and select the switch you want to access Extra Flight Modes. Alternately,
once you have the Extra Flight Mode switch options displayed, move
the switch you want to use as the Extra Flight Mode switch. The system
automatically sets that switch to be the extra flight mode switch.
Once Extra Flight Modes have been activated, two additional sets of Throttle and
Pitch curves numbered 3 and 4 appear in Function Mode.
Deactivating Channels
The 11X provides the ability to inhibit a number of channels. This is useful when
auxiliary channels are used for mixing. In this instance, the switch no longer
operates the channels allowing them to be used as slave channels. Also, the
deactivated channels assume a centered (1.50ms) position needed for mixing.
1 If using GEAR, AUX2 through AUX6 as slave channels, inhibit the
corresponding switch by highlighting ACT along the bottom line of the
display. Then press the Roller until INH appears under the switches you
want to turn off.
Normal- If using only the Aileron channel to control both ailerons, with a single
servo or with two servos connected together via a Y-harness, you should select
the NORMAL wing type. Also use NORMAL if the aircraft has flaps separate from
the ailerons. If using two aileron channels, activate the Dual aileron channel listed
below.

Flight Modes (SAILPLANE)
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 11X that include Launch, Normal, Reflex, Thermal and
Float.
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 elevatorto-flap mix. 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.
• Aileron differential is set at 50%.
You can select all programming parameters by moving one switch. You can
assign most of the switch-selectable functions in the 11X to one or more Flight
Modes. Some of these functions include: Flaperon Mix, Servo Speed, Camber
system, Differential, Aileron to rudder mix, Elevator to flap mix, Flap rate, Brake
system, trims and programmable mixes. This provides the ability to have up to
5 completely different aircraft configurations that are selectable in flight using
switches.
When 3 Flight Modes are activated, you can select them 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, the 4th and 5th flight modes are assigned
to one of the following switches: Flight Mode, Rudder D/R switch, Elevator
18
At this point, you must decide which 3-position switch you prefer to assign the
flight mode to. When a 3-position switch is selected, launch, cruise and land
will be activated. We recommend starting with the Flight Mode Switch (left
top 3-position switch), as this is a convenient place. Rotate the Roller until the
desired switch is highlighted; press to select. Alternatively, once you have the
switch options displayed, move the desired switch to automatically select the
switch.
Flap and AUX Functions
You can assign the Flap, Gear and Auxiliary channels to operate from several
different switches, buttons or the throttle stick. In Device Select, highlight the
desired Flap, Gear or Aux function. Next, press the Roller to access the available

want one servo speed, then all selectable switch positions in this screen
should be P0. If you want two servo speeds, assign the desired switch to
change the servo speed to P1. Return to the main screen.
3 If you want a single set of servo speeds, make sure the display shows Pos0.
If it does not, select Pos1 and change it to Pos0. Highlight and select the
channel and direction for each servo to be adjusted.
After you select a direction for a servo, you can set the servo speed. With
the 11X, servos can travel from .176 seconds for 60 degrees of rotation to
15.0 seconds for 60 degrees of rotation. Adjust the speed of each servo until

Throttle Curves Programmable throttle curves allows you to manipulate the throttle response
(stick position vs. throttle output), optimizing it for various maneuvers like torque
rolls. You can adjust programmable throttle with the Throttle Curve function. Two
programmable throttle curves are available- Pos0 and Pos1.
If you activated the Twin E. function in Wing Type (page 15-16 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.
Servo Speed
The 11X allows you to adjust the speed of servos on each channel in each
direction. You can reduce the speed (servo slowed) from its normal speed.
However, the function 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 is useful for scale models with retractable landing gear
and gear doors. 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.

JR 11X • RADIO INSTRUCTION MANUAL
The 11X 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, you can activate each in flight using the 3-position flight
mode switch. If you activated the additional 2 flight modes (numbers 3 and 4)
in Device Select, you will use an additional switch to activate these modes. Two
additional throttle curves will be available.
The flight mode switch offers three selectable positions:
• N=Normal
• 1=Stunt 1
• 2=Stunt 2
• 3=Stunt 3 (optional)
• 4=Stunt 4 (optional)
The N (Normal) position is used as the hover throttle curve.
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%.
Accessing the Throttle Curve Function
1. In function mode use the Roller to highlight the Thro Curve function, then
press to access. ALL SERVOS HOLD ? will display. Press YES or NO to
access the throttle curve screen.
2 Move the flight mode switch to the desired position to select the flight mode
you will program. The flight mode will display in the upper left corner of the
screen.
3 Move the Roller and highlight the desired throttle point to be adjusted. Press
21
the Roller to access the point value, then roll the Roller to increase and
decrease the point value.
4. To set throttle curves for flight modes, switch the flight mode to the desired
position; the screen will change to that flight mode.
5. Highlight the pitch point you want to adjust and press the roller. Rotate the
roller to adjust that point on the pitch curve.
6. To add a point move throttle stick to the desired position until STOR appears
on the left bottom of the screen. Pressing STOR will save a new point at that
position.
Note: To eliminate a point, press ERAS (bottom left of the screen) when the point
is highlighted.
Pitch Curve
The Pitch Curve controls variable pitch propellers. The Pitch function works
nearly identically to a programmable curve mix, allowing you to store and adjust
up to 7 points 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 smoothes the pitch
curve. Pitch must be assigned to Gear, Aux2 or Aux 3 channels in Device select
to access the Pitch function. The Pitch curve mixes the throttle channel to the
channel selected as PIT in the device select mode.
Vertical Line
Switch Select
Flap
The vertical line on the graph shows the current throttle channel position. When
the throttle channel is turned fully in one direction, the line is to the extreme left
over Point-L. When it is at neutral, it is centered over Point-1 and when 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.
There are numerous switches that can switch between 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 Device
Select function, flight mode switches may be selected. Also you can use Switch
positions (SPS) to select between Pos0 and Pos1.
To choose a switch that selects between the Pos0 and Pos1 values, highlight and
select the switch name. It will toggle between Pos0 and Pos1.
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 LAND for full flap for landing.
Graph
Flap System
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.
The 11X features a three-position Flap System with Elevator and Aileron
compensation, programmable Delay, and an Auto Land feature. It allows you to
program the flaps to three different positions, normally full flap, half flap and no
flap or fully retracted position.
Points You Can Add and Adjust
Note: The Flap System is available in the Function List only if SYS is selected on
the OUT line next to FLAP in the Device Select function in the System List.
Because flaps generally cause a change in pitch (Elevator trim), the Flap System
provides for setting an Elevator deflection for each flap position. This is called
Elevator Compensation.
The Pitch Curve defaults to three points (L, 1 and H). You can add up to four
additional points. To add a point, move the throttle stick in the desired position
until STOR appears on the left bottom of the screen. Press STOR to save a new
point at that position.
Note: To eliminate a point, highlight it then press ERASE (bottom left of the
screen).
Exponential
Point Names/Numbers
The points you adjust list vertically by name (Point-L, 1, 2, H, etc.) and display 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
The Exponential function blends the Curve between the points on the graph
to provide a smooth response. It defaults to OFF. To turn it on and smooth the
mixing curve, highlight and select OFF. It will toggle to ON.
Pitch Channel Position
The Pitch servo position next to OUT at the bottom left of the screen displays in
values from 0 to +100. It represents the servo travel corresponding to the present
Throttle Channel position.
Throttle Channel Position
This list shows the setting for each of the 7 adjustable points (Point-L, 1, 2, 3, 4,
5, H). The value of each point determines where the point positions vertically on
the graph, dictating the Pitch servo position relative to the throttle. You can set the
point values be from 0 to +100.
To change a point value, highlight and select the Point Name to the left of the
point value, then adjust the desired value.
To reset original settings, highlight a point value then press CLR.
22
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 ensures the Flaps and Elevator
reach their positions at the same time resulting in smooth Flap deployment and
retraction with minimal pitch change.
The Auto Land feature, if implemented, automatically retracts the Flaps and
Elevator compensation when the throttle is raised above a specified throttle
position. This is useful during a missed landing approach when a go-around
is required. The Flap System allows the Flaps to deploy using the Flap Switch,
Flight Mode switch or a combination of both.
To Program the Flap System
1. Highlight and select Flap System in the Function List to obtain the Flap
System display.
2 If using Auto Land, scroll to INH under AUTO THRO and select it with the
Roller. INH changes to 0 when selected.
3 Move the Throttle Stick between 0–100% to select where the Auto Land
feature is to retract the Flaps and Elevator compensation. The press STO at
the lower left corner of the screen to store the value.
We recommend 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 decreases and the stall speed of the aircraft increases
and may cause a crash if 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.
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 Roller 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 to 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 occurs when the Flaps are
deployed to their various positions. It requires some trial and error to attain the
exact values. Once properly adjusted, the aircraft will assume the proper pitch
attitude for all flap positions.
1. Adjust the Elevator compensation values (ELEV) as desired for each switch
position as you adjusted the flaps above.
AILE – Aileron Compensation
The Aileron values represent the Aileron deflection that occurs when the Flaps
are deployed to their various positions. It requires some trial and error to arrive at
the exact values. Once properly adjusted, the aircraft will assume the proper roll
attitude for all flap positions.
1. Adjust the Aileron compensation values (AILE) to the desired values for each
switch position you adjusted the flaps above.
Flight Modes
If you activated Flight Modes in the Device Select function, FM0, FM1 and FM2
appear along the right side of the Flap System display representing the 3 Flight
Modes. You must assign each of the Flight Modes one of the Flap values (NORM,
Mid, or Land). When that Flight Mode is selected during flight, the Flaps deploy
to that position. SW is also an option. When SW is selected, flap operation is
controlled by the Flap switch when in that Flight Mode.
If you did not activate Flight Modes, skip this portion of the Flap System.
The Throttle channel position appears on the bottom line of the display next to IN.
It displays in values from 0 to 100 with 50 being the center or neutral position. It
represents the present Throttle channel position.
JR 11X • RADIO INSTRUCTION MANUAL
1. For each Flight Mode, highlight and select FM0-FM2 and select either a
flap position (NORM, Mid, Land) for the flaps to assume when in that Flight
Mode, or select SW for the Flap switch to control the flaps.

Delay
Differential
The Delay feature determines how long it takes for the flaps and Elevator to reach
their positions. When the delay function is programmed, the 11X automatically
times the Flaps and Elevator to 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.
The 11X Differential function reduces the Aileron travel that deflects downward
without affecting the Aileron that travels upward. Therefore, it can eliminate
swerving tendencies in rolling maneuvers. Differential is also available for the
Rudder and Flap channels if you selected Dual Rudder and/or Dual Flap in the
Wing Type menu.
Note: Differential is available in the Function List only if the FLAPERON, Delta
or 4-Aileron is selected in the Wing Type function in the System List or a Dual
channel has been assigned to ailerons, flaps, or rudder in the Wing Type function.
The Differential function provides for 2 differential settings that are switch or
Flight Mode selectable – Pos0 and Pos1.
1. Highlight and select Delay in the Flap System display using the Roller. Then
use the rotary to select a delay between .1- second and 2 seconds.
Snap Roll The 11X 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. You can
program up to four directions and corresponding rates and assign a Direction/
Rate combination to 1 or more of the 3 Flight Modes. Press the Snap Roll switch
for the aircraft to snap roll in the direction of the rates assigned to the Flight Mode
currently selected.
You can program a Snap Roll stick switch position (STICK POS) that causes all
channels to default to the programmed snap roll position when the selected stick
is displaced further than the programmed position.
If you activated Flight Modes, up to 3 Snap Roll directions/rates can be assigned
—one per Flight Mode. If Flight Modes have not been activated then only one
direction/rate is available per snap roll (4 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 Function List. Select INH to activate a
single snap roll select S.ROLLØ.
2 Scroll to the desired channel and set it to a desired value.
3 Repeat step 2 for the other channel’s values.
4 Scroll and select the (+/-) to reverse the direction for each channel.
5 If more than one snap direction/value is desired highlight S.ROLLØ to
access the snap roll 0 thru 3 and repeat the above steps for each snap roll.
6 To set a Stick position to enter Snap Roll, highlight and select INH for the
channel desired. Either use the Roller to set the value, or move the selected
control stick to the desired position to enter a Snap Roll. Press the STO key
on the lower left. Repeat for any other stick positions to enter a Snap Roll as
desired. Highlight and select the (+/-) to reverse the stick direction.
NOTICE: Use this feature with extreme caution as it will cause the aircraft
to snap roll at any selected stick position. For safety, you should use it in
conjunction with flight modes so that in one or more flight modes this is
selected to off. This prevents the aircraft from snap rolling with any stick
position.
7 If Flight Modes are active, you can turn each Snap Roll ON or OFF in each
Flight Mode. Highlight and select the Flight Mode desired to turn the Snap
Roll function ON or OFF in each Flight Mode.
8 Highlight and select INH in the lower right corner of the screen under SNAP
SW. Roll to select the LTRM or RTRM to activate the Snap Roll on either the
Left or Right Trimmers.

To Use the Differential Function
1. Highlight and select Differential in the Function List to obtain the Differential
display.
2. If a single Aileron differential setting will be 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 choose the desired switch(s) to select between Pos0 and Pos1 differential
settings.
4 Make desired adjustments to the POS 1 differential.
Note: Pos1 always has priority over Pos0. So, if you select multiple switches
and one of the switches is in its Pos1 position, all other switches are
ignored and the Pos1 values are in effect.
5 Repeat steps 1 through 4 for the Rudder and Flap channels if activated. You
must select Dual Rudder and Dual Flap in the Wing Type menu for these
Differentials to be available.
Mode 2 set to Pos1, turning on the Aileron-to-Rudder mix. You can also
use the throttle to turn the mixer on and off. To do so, highlight and select
THRO STK. Then set the percentage of throttle to the point where the mixer
is switched on/off.
Note: You can set the Pos0 values to something other than zero causing a
different amount of Rudder deflection to occur with Aileron input. You can
then select one or more switches to toggle between the two sets of values.
With this setup there is always some mixing, indicated by either Pos0 or
Pos1, and it cannot be turned off.
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 so 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
1. In the Function List rotate the Roller until AIL-FLP is highlighted. Press the
Roller to access the Aileron-to-Flap mix.
2. Select and enter the values in the POS0 settings if using only 1 setting.
3. If 2 settings are desired, highlight and select SW SEL and select a switch.
Select and enter the desired values for POS0 and POS1.
Note: Position 1 always has priority over position 0.
4. For the aileron trim to also function on the flaps, highlight and select INH
next to INCLUDE AILE TRIM to change the setting to ACT.
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) used to turn the mixer on and off. You can use the throttle
to turn the mixer on and off by highlighting and selecting THRO STK.
Then set the percentage of throttle to the point where the mixer is to switch
between On and Off.
Rudder to Aileron/Elevator Mix
The 11X features a Rudder to Aileron/Elevator mix that eliminatesroll and pitch
coupling when rudder is applied. Two mixes are available and independent mix
values can be assigned for each direction. You can use various switches, flight
modes, the throttle stick and other stick positions (SPS) 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 Function 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. (Positive and negative values are available to reverse the
direction of the mix.)
If you want a mix value to always be active, 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
to activate mix value Pos0 and Pos1, highlight the desired switch and
choose 0 or 1. Pos1 has priority over Pos0.
Aileron to Rudder
Elevator to Flap The 11X 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 makes
coordinated turns using ailerons only.
To Program Aileron-to-Rudder Mixing
1 Highlight and select AIL-RUD in the Function List to obtain the Aileron-toRudder mix display.
2 Two sets of mixing values are 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. (You can reverse this 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
reverses the direction.
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.
4. Scroll down to the bottom line of the display to select the Flight Mode and/
or switch(s) to turn the mixer on and off. The example below shows Flight
JR 11X • RADIO INSTRUCTION MANUAL
Trim (Mechanical Trim Lever)
The 11X 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 Aileron reflex for some 3D maneuvers such
as Harriers. Typically, the flaps are set to travel downward with up Elevator and
upward with down Elevator. The direction 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 in the Function List to obtain the Elevator-toFlap mix display.
2 Two sets of mixing values are 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. (You can reverse this by leaving the Pos1 values at
zero and putting values in Pos0). Highlight and select DN next to Pos1 and
set the desired amount of Flap travel in the Down direction when full Up
Elevator is applied.
JR 11X • RADIO INSTRUCTION MANUAL
In Normal mode only, a throttle trim is available that allows you to adjust the
throttle trim. The trim value adjusts the overall trim travel of the throttle only at
low throttle in the normal mode. This adjustment helps fine-tune the sensitivity
of the throttle trimmer. To adjust the throttle trim authority, highlight TRIM and
adjust the value using the roller. You can use the onscreen graph 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.
25
Hovering Throttle
Hovering Throttle increases or decreases the servo output via the trimmer or knob
for the selected points set for the throttle curve. You can use the hovering throttle
trimmer/knob to shift the curve upward or downward in order to advance or
reduce rpm in hover. You can activate the HOV function 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.
Pitch Curve
The 11X offers up to five (5) separate pitch curves with up to 7 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.
The flight mode switch offers three selectable positions:
• N=Normal
• 1=Stunt 1
• 2=Stunt 2
• 3=Stunt 3 (optional)
• 4=Stunt 4 (optional)
Accessing the Pitch Curve Function
1. In function mode use the Roller to highlight the Pitch Curve function, then
press to access. ALL SERVOS HOLD ? will display. Press YES or NO to
access the Pitch curve screen.
2. Move the flight mode switch to the desired position to select the flight mode
you will program. The flight mode will display in the upper left corner of the

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%.
Exponential
The Exponential function blends the Pitch 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. You can use the hovering pitch
trimmer/knob to shift the curve upward or downward in order 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.

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 tail curve, highlight and select OFF and it will toggle to ON. You can select an
Expo function independently for each flight mode.
Note: Flight Modes ST-3 and ST-4 only show if activated previously in Device
Select in the System List.
Hold Delay
The Hold Delay function allows the throttle servo’s movement to slow when you
switch from Throttle Hold back to a previous Flight Mode. This feature is helpful
when practicing Autos. If you abort the autorotation attempt, when the Throttle
Hold switch is selected to the off position, the throttle increases slowly. This
eliminates the sudden burst of power and prevents damage to the gear train. The
Hold Delay adjustable range is from 1/10th of a second up to 2 seconds.
To Activate the Hold Delay
1. Highlight the Hold Delay function with the roller; press to access. Next, roll
the roller to the desired delay position, and press the roller to store. A good
starting value is .75 (3/4) of a second.
Note: To eliminate a point, press ERAS (bottom left of the screen) when the point
is highlighted.
Tail Curve -
(Use Only with Non-Heading Hold Gyros)
The N (Normal) position is used as the hover pitch curve.
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: To eliminate a point, press ERAS (bottom left of the screen) when the point
is highlighted.
The 11X offers up to five (5) separate tail curves with up to eight adjustable points
per curve. This function allows you to optimize the tail curve to counteract torque
at all pitch positions in every flight mode. Once the tail curves are established,
you can activate each using the flight mode switch(s). If you activated the
additional 2 flight modes (numbers 3 and 4) in Device Select, you will use an
additional switch to activate these modes. Two additional tail curves will be
available.
The flight mode switch offers five selectable positions:
• N=Normal

Throttle Hold
Gyro Sensor
The Throttle Hold function holds the throttle output position in a specific position
when the throttle hold switch is activated. But it still allows full pitch and cyclic
control. Throttle Hold is normally used for autorotations or as a throttle safety
switch with electric models.
The 11X offers three different types of Gyro Gain Sensitivity Adjustments: manual,
flight mode or automatic. This feature gives you 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). You
can set up the gyro program 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 to conventional mode. This
prevents the tail from jumping when switching modes. It can be toggled on or off.
The Throttle Hold switch defaults to the top right-rear corner of the transmitter.
However, you can select a different switch in the Device Sel section in System
Mode. In the forward position, Throttle Hold is on; in the rear position, Throttle
Hold is off.
Accessing the Throttle Hold Function
1 Highlight and select Throttle Hold in the Function List to obtain the Throttle

Note: When Throttle Hold is activated and the switch is on, the “HOLD”
indication on the main screen displays on the lower right side of the screen.
Stick Auto
The Stick Auto function allows you to activate throttle hold automatically when
the Throttle Hold switch is activated and throttle reduced below the programmed
position. Although the Throttle Hold switch is active, with this feature the throttle
continues to function until you move the throttle stick below the cut position you
select.
Note: To access the gyro function, you must program the Gear, Aux1 or Aux 2
channels to GYR in device select code 17. You must plug the gyro gain lead into
this channel.

Governor
The 11X Governor function is designed to be used with most currently available
Governors. The function allows you to set rpm values for each of the Active Flight
modes. The Governor rpm values will automatically change when the Flight Mode
switch is moved to each of the active flight modes.
The value range in the Governor function is –125% to 125%. These values follow
the Travel Adjust values. In other words, a desired Travel Adjust value of +55%
would also be +55% in the Governor function. You can assign the Governor
program’s operational channel to the Gear, Aux1 or Aux2 channels in the Device
Select screen.
Note: To access the Governor function, you must program the Gear, AUX1 or
AUX 2 channels to GOV in device select code 17. The governor lead must aslo be
plugged into this channel.

1 Move the Roller to highlight the Governor function. Press the Roller to
access.
2 Highlight the value you want to adjust with the Roller, and then press to
access the value. Roll the Roller to adjust the value as needed.
Swash Mix
The Swash Mix screen has several important functions. These functions include:
and aileron. 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 nonlinearity at the extremes of travel. This function should always be turned on.
Note: You must select the swashplate type in the Swash Type function in the
System List.

switches and flight modes to turn on/off the mix function.
5 To activate the 3D cyclic ring, highlight INH next to E-RING. Toggle the roller
to ACT.
6 To activate the exponential function, highlight OFF next to EXP. Toggle the
roller to ON.
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 endpoints is affected by the trim values. The right trim causes
the center, the right endpoint and the left endpoint 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.
To Adjust the Trim Rates
1 Highlight and select Trim System in the Function List to acquire the Trim
System function.
2 Highlight and select the trim that is to be changed and use the Roller 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.
Aileron, Elevator and Pitch
Authority
This function independently adjusts the maximum travel of the servos working
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) increase travel
when the ailerons are deflected. This will not affect pitch or elevator travel.
Conversely, if you increase the pitch value, all three servos (aileron, elevator and
pitch) 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
you can select a – (negative) value. The adjustment range is from -125 to +125%
(defaulted to +60).
Aileron to Elevator/ Elevator
to Aileron Mix
This mix corrects swashplate interactions. For example, you can correct elevator
input that results in slight roll output by mixing elevator to opposite aileron. You
can select switches or flight modes (SE SEL) to turn this mix on/off. Generally,
this mix is turned on in stunt modes only.
3D Electronic Cyclic Ring (E-Ring)
When active, the 3D electronic cyclic ring prevents the cyclic servos (aileron,
elevator and pitch) from overdriving when you give a command of full elevator
28
To Select the L.S.T. Trim Function
1 Highlight and select the L.S.T. or NORM setting next to the desired channel
(AILE, ELEV or RUDD) and press the roller to select L.S.T. or NORM.
2 Repeat for other channels as desired.
Trim System
The Trim System function adjusts the sensitivity of the 11X trim levers and the
Flap and Aux 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 Flap and Aux
Trimmers 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.
The trimmers can also be set to function as a momentary switch by selecting
ON under Moment for either or both trimmers. 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; use a finer setting, such as 3–1, for final precision trimming.
JR 11X • RADIO INSTRUCTION MANUAL
3 Rotate the roller to adjust the value.
4 Repeat for all positions and flight modes as desired.
Motor System
Note: This function is only available when the motor is programmed to the
spoiler stick in the Device Select menu.
The Motor System feature allows the spoiler stick to be used for multiple
functions. In one mode (Launch Mode, for example) you can use it as a
proportional throttle for an electric motor. Switching to another mode (Float), you
can use the spoiler stick as landing flaps. When the Motor System mix is on, the
Motor System program holds the throttle in the desired position, usually motor off.

access the Motor System menu.
2 Rotate the Roller to highlight desired flight mode or switch, then press the
Roller to access on or off.
3 Adjust the motor value to achieve the desired throttle position for that flight
mode or switch.
Note: The AND function requires all selected switches to be On in order to
activate the Motor System function. If AND is left Off, only one of the
selected switches need be On to activate the Motor System function.
4 A delay can be added when the motor is throttling up and when throttling
down. Both delays are adjustable from 0 to 2 seconds. To add a delay on
throttling up, highlight and select INH next to the up arrow, and adjust the
value as desired. To add a delay on throttling down, highlight and select INH
next to the down arrow. Adjust as desired.
Slide Camber
Camber Preset
The Slide Camber function adjusts the up and down flap travel when using the
Flap Lever (default) or whichever switch you selected to operate the flaps in
Device Select. Each flight mode activated in Device Select will display with an
up and down value in the Slide Camber screen. The adjustment range is +125%
to-125%. Use Slide Camber in conjunction with the Flaperon Mix function to
adjust the desired camber setting ranges, when using the flap levers for each
flight mode.
To Access the Slide Camber Function
1 Highlight and select Slide Camber in the Function List.
Note: Flap values are available for each active flight mode, and you can
independently adjust the values up and down.
2 Rotate the roller to highlight the value next to the flight mode. Press the
Roller to access the Slide Camber for the intended flight mode and press the
roller.
The Camber Preset 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. It also allows you to adjust the preset
camber setting that is automatically selected with each flight mode.
The available Delay function causes the smooth transition of the control surfaces
from one flight mode to the next. Plus, a Break function is available that reduces
the camber at a preset elevator stick position. Flap and Flaperon trim steps are
also adjustable in the Camber Preset system.
JR 11X • RADIO INSTRUCTION MANUAL
The Camber Preset system combines four mixes in one screen. Mixes include
Flap- to-Flaperon mix, Flap-to-Elevator mix, Aileron-to-Flap mix, and Aileron-toTip 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. You can program the flap functions to one of many different
29
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 you program a flap
value in the Slide Camber function, the Flaperon Mix function will not operate.
To Access the Camber Preset system
1 In the Function List rotate the Roller until Camb Preset is highlighted. Press
the Roller to access the Camber Preset menu.
2 If you wish to program a Break point with elevator input (reduces camber
with elevator input), highlight Elevator STK and program the desired Elevator
offset. This value establishes the point at which the reduction of camber
occurs.
3 Rotate the Roller to highlight the desired value then press the Roller 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, you can program a delay that smoothly transitions the control
positions when changing from one flight mode to the next. The adjust range
is from INH to 6.0 seconds or hold.
2 Highlight Flap LV Offset and program the desired Flap lever offset. This
value establishes the center point at which the up/down or left/right mix
occurs. 0 is center position.
Note: The flap defaults to the left lever but can be changed in Device Select.
3 Rotate the Roller to highlight the desired value then press to access. With
the flight mode switch in the corresponding mode, move the programmed
flap lever to the appropriate position and adjust the value to the desired flap
position. Repeat this for all desired flight modes and flap positions.
4 Press the LIST button to return to the Function Mode screen.
Differential
Aileron-to-Rudder Mix
The 11X 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. Differential is also
available for the Rudder and Flap channels if Dual Rudder and/or Dual Flap is
selected in the Wing Type menu.
Landing Mode
The Landing Mode mixes the spoilers, flaperons, flaps, and tip ailerons (if
equipped) and elevator to the spoiler (throttle) stick. Two values are available,
Pos0 and Pos1. You can assign each to several different switches or flight modes.
The provided offset (Brake Start POS) allows the user’s preference for the neutral
position (normally stick up).
To Access the Landing Mode
1 In the Function List rotate the Selector until Landing Mode is highlighted.
Press the Selector to access the Landing Mode function.
Note: The default setting for Brake Start POS offset position is at +95%.
With this setting, the flap’s neutral position (trailing edge level) occurs when
the spoiler stick is in nearly 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 SEL. Press the Selector to access the
available switches. Select a switch and switch position if desired. Highlight
and select SW SEL to exit the switch selection list.
3 To access the various values, rotate the Selector to highlight them. Press the
roller 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 Rotate the roller to access the Landing Flaperon and Elevator mixes. These
allow you to store and program up to 7 points. This system also allows up
to 7 points on a curve to be adjusted for Flap-to-Elevator mixing and Flapto-Flaperon Mixing.
5 Move the spoiler stick up and down until you see ADD on the lower left
corner of the screen. When in the stick position desired, press ADD to add
an additional point to the curve mix.
6 Adjust each mix value as desired.
7 Press the LIST button to return to the Function Mode screen.
The Aileron Differential function provides independent differentials for each flight
mode. A Break feature adjusts the point at which the differential begins based on
the Spoiler Stick.
To Use the Differential Function
1 Highlight and select Differential in the Function List to obtain the Differential
display.
2 Select the desired Flight Mode and set the Aileron differential as desired. 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 you want to use a Break to activate the Differential based on Spoiler Stick
position, select the Break value for each Flight Mode and adjust as desired.
Adjust the value so the differential begins where desired on the Spoiler
Stick.
4 Repeat steps 1 and 2 for the Rudder and Flap channels if activated. Dual
Rudder and Dual Flap must be selected in the Wing Type menu for Rudder
and Flap Differential to be available.
To Access Aileron-to-Rudder Mix
1 In the Function List rotate the Roller until AIL-RUD is highlighted. Press the
Roller to access the Aileron-to-Rudder mix menu.
2 Rotate the Roller to highlight the desired value corresponding to the flight
mode and desired direction. Press the Roller to access that value. With the
flight mode switch in the corresponding mode, give an aileron command
and rotate the Roller to achieve the desired rudder value. Press the Roller to
store the value.
3 You can program Elevator and rudder break points. They reduce the aileronto-rudder mix when the elevator or rudder stick is displaced.
Snap-Flap Mix
The Snap-Flap mix gives several degrees of down flap when up elevator is
applied. This gives more pitch authority than would elevator alone. Snap-Flap
mix values are available for each active flight mode and can be independently
adjusted up and down.
Flaperon Mix
Flaperon Mix Combines four mixes in one screen. Mixes include Flap-toFlaperon 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 you to choose the neutral position.
You can program the flap functions 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 you program a
flap value in the Flap Rate function, the Flaperon Mix function will not operate.
To Access Flaperon Mix
1. In the Function List, rotate the Roller until Flaperon Mix is highlighted.
Press the Roller to access the Flaperon Mix menu.
30
Aileron-to-Rudder mix causes the rudder to move in unison with the ailerons. You
can use it to reduce adverse yaw and improve turning/handling characteristics.
You can independently adjust Aileron-to-Rudder mix values right and left for each
of the 5 flight modes.
JR 11X • RADIO INSTRUCTION MANUAL
An offset is available that allows the programming of snap-flaps. With snap-flaps,
there is no flap mixing during small-to-medium up-elevator inputs. However, at
the offset point of up-elevator, the flaps are mixed to give down flaps, causing
greater up-pitch authority
Switches are available at the bottom of the screen that allow the selection of
Pos0 or Pos1.
Rudder-to-Spoiler Mix
The Rudder-to-Spoiler mix causes the spoiler to move in unison with rudder. You
can independently adjust Rudder-to-Spoiler mix values for each of the 5 flight
modes.
Note: Dual spoilers must be activated in Wing Type in order to access the
Rudder-Spoiler mix.
Flight Tip: You can use this mix to improve turning/handling characteristics,
especially on landings.
To Access Rudder-to-Spoiler Mix
1 In the Function List rotate the Roller until RUDD-SPOI is highlighted. Press
the Roller to access the Rudder-to-Spoiler mix menu.
2 Rotate the Roller to highlight the desired value corresponding to the flight
mode. Press the Roller to access that value. With the flight mode switch in
the corresponding mode, give a rudder command and rotate the Roller to
achieve the desired spoiler mix value. Press the Roller to store the value.
Introduction to Mixers
The 11X provides 3 Standard programmable mixes (PROG. MIX1 - PROG.MIX3)
and 3 Multi-Point or Curve programmable mixes (PROG.MIX4 - PROG.MIX6).
Programmable mixers are programmed to cause a second channel to react to
input to the primary channel or to cause a channel to be controlled by moving
a switch or lever. The primary channel is called the Master channel, while the
channel that reacts to the Master is called the Slave channel.
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 you can program down elevator at low
throttle for aerobatic aircraft such that the aircraft tracks perfectly on the down
lines at low throttle.
Flight Tip: Snap-Flap is commonly used by slope racers to improve high-speed
turns. In thermal sailplanes, it allows increased maneuverability for tight thermal
turns.
Multi-Point (or Curve) Mixing provides the ability to program a customized curve
that the Slave channel follows as it reacts to the Master channel’s input. Multi
Point mixes are different from Normal Mixes in that Normal Mixing results in a
restricted movement of the Slave channel in relation to the Master. With MultiPoint Mixing you can adjust up to 7 points to control the position of the Slave
channel, providing the ability to custom tailor the output of that channel.
To Access Snap-Flap Mix
1 In the Function Mode list, rotate the Roller until Snap-Flap is highlighted.
Press the Roller to access the Snap-Flap mix menu.
2 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.
Mixes are fully programmable, allowing any of the 11 channels to be Master,
Slave or both (a channel can be mixed to itself). You can also use trimmers and
levers as a master and 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/
JR 11X • RADIO INSTRUCTION MANUAL

Trainer, switch (momentary switch SNPT) can also be programmed as the Master
channel.
To enter Pos0 values, highlight and select Pos0. Move the Master channel control
(stick, lever or switch) in one direction and set the percentage. Then move the
Master channel control in the other direction and set its value.
If you activate dual functions 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.
There are 2 options for Master channels:
“#” (pound sign). These Master channels are Origin-type mixes. Origin
mixing bypasses any other mixing affecting that channel, such as throttle curves,
exponential or travel adjust, and uses the stick position only to control the mix.
Pos1 settings are identical to the Pos0 settings. They determine how far, and in
which direction, the slave channel moves when the master is moved above and
below the offset and the switch is in a position to select Pos1 values.
Slave Channel - (Std. Prog Mixer)
“+” sign. These Master channels are include-type mixes. Trim Include mixes
include the trim of the Master channel and any other mixing to the Master channel
if selected to control the Slave channel of the mix.
The Slave channel is the secondary receiving channel and moves according to the
program mix in relation to the Master channel. The default for both the Master the
Slave channel is THRO.
Functions of the Standard
Programmable Mixer
Highlight and select the Slave parameter to obtain a list of channels. Then select
the Slave channel from the list. The list contains each of the 11 channels in the
system and CANCEL.
Standard Programmable Mixer - (Std. Prog Mixer)
The 11X has 3 standard programmable mixers that allow linear mixing of a
Master channel to a Slave channel. The standard mixers are PROG.Mix 1, Mix 2,
and Mix 3.
These mixes provide two sets of mixing values named Pos0 and Pos1. If one set
of values is set to 0%, you can turn the mixer On and Off with a stick, switch, or
lever. Each set of mixing values has 2 percentages to accommodate movement of
the Master channel in both directions. This is shown in the illustration below with
an upper and lower percentage for both Pos0 and Pos1.
You can set a mix to always be on by setting Pos0 values only and not selecting
any switches to switch between the Pos0 and Pos1 values.
Switch Position
The left side of the Programmable mix screen displays the available switch
options. If you want a switch to 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.
Offset
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. Highlight and select the Master parameter to
obtain a list of channels. Select the Master channel from the list.
If the master channel selected is capable of include or origin mixing, a pop-up
menu will appear with a list of include functions available. Generally, you can
include the Trim, so the trim for the master channel also functions on the slave
channel. Additionally, you can set D/R & EXP settings and some mix functions to
include, so they function on the slave channel as well.
If all include settings are set to OFF, then the mix is an Origin-type mix. In such
a mix only the master channel control stick or switch functions on the slave
channel.
CLR Button - (Std. Prog Mixer)
Slave Channel
Pressing the CLR button with a modifiable mix selected resets the parameter to
its default value. Pressing the CLR button when the Master or Slave channel is
highlighted Inhibits the entire mix, making it 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
This list shows the setting for each of the 7 adjustable points (Point-L, 1, 2, 3, 4,
5, H). The value of each point determines where the point is positioned vertically
on the graph, dictating the Slave servo position relative to the Master. You can
set the point values 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.
To change the value for a point, highlight and select the Point Name to the left of
the point value. Then dial in the desired value.
Pressing the CLR button when a point value is highlighted resets the point to
original settings.
Vertical Line
The Vertical line on the graph shows the current Master channel position. When
you deflect the Master channel fully in one direction, the line is to the extreme
left over Point-L. At neutral, the Master channel is in the center over Point-1.
When 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 Slave servo position, which is equal to the value assigned
to that point.
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. The bottom half of the graph is one direction from neutral, and the top
portion of the graph is the other direction.
Points You Can Add and Adjust
Offset defines the position where the mixer changes direction. The Offset defaults
to center position or 0 and is most commonly used. With a 0 Offset, if the Rudder
is Master, moving the rudder stick to the left of center causes a mix in one
direction while moving the rudder stick of 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 the slave moves is determined by the Pos0/Pos1 values. Offset applies
to both Pos0 and Pos1 settings.
There are 3 Multi-Point Programmable Mixers in the 11X - Prog. Mix4 through
Prog.Mix6. They differ from standard mixes because they allow non-linear mix
response from the Master to the Slave. They use up to 7 points to define the
position of the slave channel in relation 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.
Exponential
Point Names/Numbers
Mix Values
JR 11X • RADIO INSTRUCTION MANUAL
Curve mixes default to three points (L, 1 and H). You can add up to four
additional points. To add a point, move the master channel in the desired position
until STOR appears on the left bottom of the screen. Press STOR to save a new
point at that position.
To eliminate a point, press ERASE (bottom left of the screen) when the point is
highlighted by moving the master channel.
To change Offset, highlight and select Offset and adjust with a positive (+) or
negative (-) value. A positive percentage moves the offset in one direction from
center while a negative percentage moves it in the other direction from center.
Pos0 settings determine how far, and in which direction, the slave channel moves
when the master is moved above and below the Offset and the switch is in a
position to select the Pos0 values.
32
To enter Pos1 values, highlight and select Pos1, move the Master channel control
(stick, lever or switch) in one direction and set the percentage. Then move the
Master channel control in the other direction and set its value.
Current Point Setting
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. It will toggle to ON.

Slave Channel Position
F-Mode Delay
The Slave servo position next to OUT at the bottom left of the screen displays
in values from -100 to +100. 0 is neutral or center. This position represents the
servo travel that corresponds to the present Master channel position.
You can use the Flight Mode Delay function to delay the transition from a stunt
mode to normal flight mode. The delay function slows the selected channel’s
changes that are caused by switching from a stunt mode to normal flight mode.
Some of those changes include throttle curves, pitch curves, Dual Rates, etc.
This is useful for transitioning from a stunt mode with a V-pitch curve to normal
mode with a linear curve to slow the transition and prevent the helicopter from
jumping quickly.
Master Channel Position
The Master channel position displays on the bottom line of the screen next to
IN. It is expressed in values from 0 to 100. 50 is center or neutral. This position
represents the present Master channel position.
To Program a F-Mode Delay
1 Highlight and select F-Mode Delay using the Roller in the Function List.
2 Highlight and select INH next to the desired channel to apply a delay.
3 Rotate the roller to adjust the setting from INH to 6.0 seconds.
Mix to Throttle
Gyro Gain System [Sensor]
The 11X Cyclic-to-Throttle function adds throttle to prevent main rotor rpm decay
that results from load changes placed upon the engine when Aileron, Elevator or
Rudder is given. The most common use for Cyclic-to-Throttle mixing is for Stunt
Modes. This allows the main rotor rpm to remain consistent throughout aerobatic
and 3D maneuvers. Normally, Cyclic-control to-Throttle mixing is not used in
Hover (Normal) mode since control inputs are generally small and much less
aggressive.
Note: If you are using a Governor for rpm control, it is not necessary to use the
Cyclic-to-Throttle Mixing. Further, 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 Roller to
access the Mix-Thro screen.
2 Highlight the value you want to adjust, then press to open the options box.
Roll the Roller to adjust the value as needed.
The Gyro Gain system allows in-flight selection of up to 3 gyro gain settings
for up to two separate gyros, or up to three gyro gain settings assigned to flight
modes. The system provides for fixed gain values and has settings for normal or
tail lock gyros. You can assign and select Gyro gains via a three-position switch
or with Flight Modes.
If one set of gains for a gyro is set to 0% in normal gain mode, you can switch the
gyro off during flight.
Gyro Connections
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 using
only one gyro, connect its gain to either AUX2 or AUX3.
Gyro Sensor [Gain]
Selecting the Desired Flight
Modes for Cyclic-to-Throttle
Mixing
The 11X allows you to select the specific flight modes in which the Cyclic-toThrottle mixing will be active. The factory default position is ON for all flight
modes, which is not recommended in most cases. The Cyclic-to-Throttle mix is
generally used for Stunt (flight) modes only, so it will be necessary to select the
Cyclic-to-Throttle mixing for the desired flight modes.
1 Move the Roller to highlight the SW SEL for each of the Cyclic-to-Throttle
mixes to be used.
2 Press the Roller to open the Flight Mode options box. Highlight the desired
flight mode to be set (NRM, ST1, ST2, ST3, ST4, GEAR). Press the Roller to
turn the mixing on or off for each of the active flight modes.
34
In order for the Gyro Sens to appear in the Function List, you must program the
Device Select function to GYRO on the GEAR, FLAP, AUX2 and/or AUX3 channels
to be active.
Use this function 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.
To Access the Gyro Sensor
1 Highlight and select Gyro Sens. in the Function 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, AUX2 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. If selecting heading lock, note that a T
or N is available for each gain setting. If T is selected, the gyro will be in tail
lock mode. If N is selected, all values for that gain will be in normal mode.
For most airplane applications normal mode is recommended.
Note: Time Lag is available in Tail Lock mode when switching from tail lock
to normal mode. This prevents the servo attached to the gyro from jumping
abruptly when switching from tail lock to normal mode.
JR 11X • RADIO INSTRUCTION MANUAL
4 Each gyro has 3 available gain settings. They are labeled Pos0, Pos1, and
Pos2 with a percentage next to each. They correspond to the positions of
a 3-position switch. 0 represents the switch being in the upper position; 1
represents the middle position; and 2 represents the lower position.
5 Use the Roller 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.
Trim System
To Select the L.S.T. Trim Function
1. Highlight and select the L.S.T. or NORM setting next to the desired channel
(AILE, ELEV or RUDD). Press the roller to select L.S.T. or NORM.
2. Repeat for other channels as desired.
Throttle Hold
The Trim System function adjusts the sensitivity of the 11X trim levers. 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, but 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.
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. Use a finer setting, such as 3–1, for final precision trimming.
Also in the Trim system function if flight modes are active, you can select the
flight mode trims to be common, the same set of trims in every flight mode, or
select FMOD to have a different set of trims for each flight mode. You can set the
Flap trim to on or off in the Trim System function as well. Finally, you can leave
the Flap and AUX levers at the default setting as well as CROSS, which swaps the
functions of the 2 levers.
The throttle hold function acts as a kill switch for glow-powered airplanes
and a safety/arming switch for electric-powered aircraft. You can also 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 the Device Select screen in System Mode.
Note: Throttle Hold defaults to the mix switch.
To Activate Throttle Hold
1 Highlight and select Thro Hold in the Function 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 displayed under ACT. MIX
SW is the default setting. To select another switch see Device Select Throttle
Hold on page 14.
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 and endpoints are affected by the trim values. The right trim causes the
center, right endpoint and left endpoint 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.
To Adjust the Trim Rates
1 Highlight and select Trim System in the Function List to acquire the Trim
System function.
2 Highlight and select the trim you want to change. Use the roller to set a
value of 1–10 (1 = finest, 10 = coarsest).
3 Repeat for other trims as desired.
JR 11X • RADIO INSTRUCTION MANUAL
Throttle Trim
The Throttle Trim function allows a throttle cut feature that cuts the throttle to
an adjustable setting to kill the engine on a selected switch. An idle adjustment
feature is also available allowing 2 selectable idle positions through a switch.
To Program the Throttle Cut Function
1 Highlight and select INH under THRO CUT.
2 Highlight and select the percentage next to THRO to adjust the position the
throttle moves to when the function is activated by a switch. Adjust this
position as necessary so the engine stops running, but does not bind the
throttle linkage.
3 You can add a Time Lag to delay the throttle cut function. Highlight and
select INH next to Time Lag and rotate the roller to select the desired Time
Lag. The value ranges from INH to 2.0 seconds.

6 Highlight SW SEL to exit the switch selection menu.
Stick Position Switch
To Program the Idle Adjust Function
1 Highlight and select SW SEL under IDLE ADJUST on the screen.
2 Rotate the roller to select the switch and switch position desired. Press to
select.
3 Highlight SW SEL to exit the switch selection menu.
4 Highlight and select +0 under the Idle Adjust and rotate the roller to adjust
the idle position as desired.
Balance
The Balance function allows you to adjust the servo outputs of dual channels.
This is useful when two servos are used to drive a single surface (e.g., two aileron
servos used to drive one aileron) and the linkage geometry of each servo is
slightly different (typical with a tapered aileron).
If you mix both servos in a linear fashion, binding occurs throughout the control
range due to linkage geometry inaccuracies. The Balance function allows you
to adjust the servo output of the master servo at 5 points throughout the range,
compensating for any linkage geometry inaccuracies. Think of Balance as a curve
mix that allows you to independently adjust the master channels at seven different
points. This allows a perfect bind-free setup throughout the control stroke.
To Program the Balance Function
Note: Balance is available in the Function List only if Flaperon, Delta or
4-Aileron is selected in the Wing Type or if any of the dual functions (e.g., dual
elevator, dual rudder, etc.) are activated in Wing Type.
1 Highlight and select Balance in the Function List.
2 Highlight and select the channel you wish to adjust on the left side of the
screen.
3 The Balance screen displays functions that are programmed in the Wing
Type. If Flaperon only is programmed, only one aileron channel appears in
the balance screen. If 4-Ailerons are selected, then three aileron channels
appear in the balance screen. This also applies to the dual elevator and
rudder functions.
4 Using the roller, highlight the desired position and press the roller to access
the value. Rotate the roller to change the selected output position. The
range is +50 to -50. Repeat this for all positions until no binding occurs
throughout control travel or the left versus right travel is matched. Point P-2
adjusts that channel’s neutral point, points P-1 and P-3 adjust that channel’s
100% travel adjust point, points P-L and P-H adjust the selected channel’s
150% travel adjust point.
5 If Expo is desired, highlight OFF under EXP and press the roller to select
ON. Expo will apply a curve response between the points selected.
36
The Stick Position Switch function allows the throttle, aileron elevator or rudder
stick positions to turn on/off mixes, change throttle curves, change differential
rates, start a timer and other functions. An example of this would be a smoke
system that turns off below 25% throttle to prevent low throttle flameouts. Two
stick position programs are available and you can assign one or more 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.

Frequently Asked Questions
on Spektrum 2.4GHz
Your DSM2 equipped 2.4GHz system is intuitive to operate, functioning
nearly identically to FM systems. Following are a few common questions from
customers:
Q: After I’ve bound the receiver to my transmitter, which do I turn
on first when I want to fly?
A: Either one. Every DSM 2.4GHz transmitter has a GUID (Globally Unique
Identifier) code imbedded in its signal. When you bind a DSM receiver
to your transmitter, this GUID code is stored in the receiver. If you turn
the receiver on before the transmitter, you don’t have to worry about it
responding to another transmitter. The receiver will inhibit throttle output
and drive all controls to preset positions while it waits for a signal from the
transmitter with the same GUID code it has stored.
If a DSM transmitter is turned on first you can expect it to connect within 6
seconds of powering on the receiver.
Q: Sometimes the system takes longer to connect or doesn’t
connect at all. Why?
A: In order for a DSM system to connect, the receiver must receive a large
number of uninterrupted signal packets from the transmitter. This process
takes just a few seconds, but if the transmitter is too close to the receiver
(within 4 feet) or near metal objects it may detect its own reflected 2.4GHz
energy as “noise”. This can delay or prevent connection.
If this happens make sure you are a sufficient distance from metal objects
and the receiver itself before you power up and try again.
Q: Is it true that DSM systems are less tolerant of low voltage?
A: All DSM receivers require at least 3.5V to operate normally. Most servos
cease to operate below 3.8V. Using multiple high-voltage servos, however,
with an inadequate power supply can allow voltage to momentarily drop
below 3.5V. This will cause the receiver to “brown out” and reconnect.
All recently manufactured JR and Spektrum DSM receivers feature
QuickConnect technology that will reconnect the system within a quarter of
a second should a brownout occur. In addition, the receiver’s LED will flash,
indicating a brownout has occurred. If after landing you notice your DSM
receiver’s LED is flashing, make sure you have adequate power before you
fly again.
General Information
Servo Precautions
Q: Sometimes when I power on my DSM system I notice the
receiver won’t connect and it needs to be rebound to the
transmitter. Can this happen in flight?
A: No. A DSM receiver cannot be unbound from its transmitter without specific
action by the user.
You can accidentally unbind a receiver by inadvertently pressing the bind
button on your transmitter when you turn it on. This causes the transmitter
to go into bind mode. If this happens and the transmitter doesn’t detect a
binding signal from the receiver it can cause the receiver to be unbound.
Some transmitter stands can cause the bind button to be depressed during
power up, but these instances are extremely rare.
If your system fails to connect, chances are much greater that it’s the result
of one of the following conditions and not because the receiver is unbound.
1. You’ve selected the wrong model memory.
2. The transmitter is too close to conductive material to connect
(see FAQ #2).
Q: How important is it that I test my system using a Spektrum
Flight Log?
A: All 2.4GHz signals, not just DSM, are affected by proximity to conductive
materials such as carbon fiber or metal. Few RTF and ARF sport airplanes
or helicopters use enough of these kinds of materials for it to be an issue.
If, however, you’re flying a sophisticated model that uses a lot of conductive
materials in its construction, a Flight Log can be helpful. The information it
collects when you fly will help you determine the optimum location for your
receiver(s) so you can minimize the effects of these materials on your signal
performance. For more details on the Flight Log and how it works, visit
SpektrumRC.com.
• Do not lubricate servo gears or motors.
• 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.
• 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.”
• 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.
• Ensure the servo horn is securely fastened to the servo. Use only the servo
arm screws provided; the size is different from other manufacturers.
• 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.
Safety, Precautions, and Warnings
As the user of this product, you are solely
responsible for operating it in a manner that does
not endanger yourself and others or result in
damage to the product or the property of others.
Carefully follow the directions and warnings for
this and any optional support equipment (chargers,
rechargeable battery packs, etc.) that you use.
This model is controlled by a radio signal that
is subject to interference from many sources
outside your control. This interference can cause
momentary loss of control so it is necessary to
always keep a safe distance in all directions around
your model, as this margin will help to avoid
collisions or injury.
38
JR 11X • RADIO INSTRUCTION MANUAL
JR 11X • RADIO INSTRUCTION MANUAL
• Always operate your model in an open area away from cars, traffic, or
people.
• Avoid operating your model in the street where injury or damage can occur.
• Never operate the model out into the street or populated areas for any
reason.
• Never operate your model with low transmitter batteries.
• Carefully follow the directions and warnings for this and any optional
support equipment (chargers, rechargeable battery packs, etc.) that you use.
• Keep all chemicals, small parts and anything electrical out of the reach of
children.
• Moisture causes damage to electronics. Avoid water exposure to all
equipment not specifically designed and protected for this purpose.
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
This advisory outlines safety standards for
operations of model aircraft. We encourage
voluntary compliance with these standards.
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:
39
a. Exercise vigilance in locating full-scale aircraft (get help if possible) so as not to
create a collision hazard.
b. Select an operating site at sufficient distance from populated areas so you do
not create a noise problem or a potential hazard.
c. Do not fly higher than 400 feet above the surface.
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.
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.

Director, Air Traffic Service Federal Aviation Administration, Washington, D.C.
Daily Flight Checks
1. Check the battery voltage on both the transmitter and the receiver battery
packs. Do not fly below 4.3V on the transmitter or below 9V on the receiver.
To do so can crash your aircraft.
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.

Antenna Separation Distance
Appendix
Advanced Range Testing
Flight Log JRPA145 - Optional
for JR R921 Receiver
The Flight Log is compatible with the JR R921 receiver and many other
compatible 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 receiver. The screen automatically displays voltage e.g.,
6v2= 6.2 volts .
Note: When the voltage reaches 4.8 volts or less, the screen flashes indicating
low voltage.
Using the Flight Log
Press the button to display the following information:
• A - Antenna fades on internal antenna A
• B - Antenna fades on external antenna B
• L - Antenna fades on the left external antenna
• R - Antenna fades on the right external antenna
• F - Frame loss
• H - Holds
When operating your Spektrum transmitter, please
be sure to maintain a separation distance of at least
5 cm between your body (excluding fingers, hands,
wrists, ankles and feet) and the antenna to meet
RF exposure safety requirements as determined by
FCC regulations.
Antenna fades—represents the loss of a bit of information on that specific antenna.
It’s typical 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, reposition the
antenna in the aircraft to optimize the RF link.
The illustrations below show the approximate 5 cm
RF exposure area and typical hand placement when
operating your Spektrum transmitter.
Holds are indicated when 45 consecutive frame losses occur.
This takes about one second. If a hold occurs during a flight, it’s important to
re-evaluate the system. Move the antennas to different locations and/or check to
be sure the transmitter and receivers are working correctly.
Frame loss—represents simultaneous antenna fades on all attached receivers.
If the RF link is performing optimally, frame losses per flight should be less than
20.
Note: You can use a servo extension to plug the Flight Log 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.
Advanced Range Testing Using a Flight Log
For sophisticated aircraft that contain significant amounts of conductive materials
(e.g., turbine-powered jets, some types of scale aircraft, aircraft with carbon
fuselages, etc.) the following advanced range check confirms internal and remote
receivers are operating optimally and the receiver installation is optimized for the
specific aircraft. Before each flying session, and especially with a new model, it’s
important to perform a range check. The 11X 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.
Control Stick Tension
Adjustment
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 display
by pressing the button on the flight log.
Have a helper hold your aircraft while observing the Flight Log data. Stand 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 transmitter, nose away from the transmitter, etc.) while watching
the Flight Log. Note any correlation between the aircraft’s orientation and Frame
Losses. Do this for 1 minute. You can use the timer on the transmitter.
For giant-scale aircraft, tip the airplane up on its nose and rotate it 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 than ten recorded
frame losses.
Stick tension adjustments are accessible by removing the back half of the
transmitter case. Remove the 6 screws with a medium Phillips screwdriver, then
carefully pull the back half of the transmitter case off gently. Set the case to the
side using care to not damage the wires. Using a small Phillips screwdriver,
adjust each gimbals’ tension screw for the desired tension (counterclockwise to
loosen stick tension; clockwise to tighten stick tension).
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.
3.
A successful Advanced test yields the following:
• H- 0 holds
• F- Less than 10 frame losses
• A, B, R, L- Frame losses will typically be less than 100.
4.
It’s important to compare the relative frame losses. If a particular receiver has a
significantly higher frame loss value (2X to 3X), redo the test. If the same results
occur, move the offending receiver to a different location.

4.Throttle Tension Adjustment
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) 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.
Neck Strap Attachment
The face of the 11X transmitter has an eyelet for connecting a Neck Strap.
