SAFETY
GENERAL
This is a high-output, full-range radio control system that should well exceed the range needed for any surface Model. For safety,
the user should perform a range test at the area of operation to ensure that the radio control system has complete control of the
Model at the farthest reaches of the operational area. Rather than operating the Model, we recommend that the user enlist the
help of a fellow modeler to walk the Model to the farthest reaches of the track (or for boats, to walk the shore line well in excess
of the operational distance of the boat), then test for proper operation.
• Be certain to read this User's Guide in its entirety.
• 'Safety First' for yourself, others and your equipment.
• Observe all the rules of the field, track or lake where you operate your radio control equipment.
• If at any time during the operation of your Model, should you feel or observe erratic operation or abnormality, end your operation
as quickly and safely as possible. DO NOT operate your Model again until you are certain the problem has been corrected.
TAKE NO CHANCES.
• Your Model can cause serious damage or injury. Please use caution and courtesy at all times.
• Do not expose the radio control system to water or excessive moisture.
• Waterproof the receiver and servos by placing them in a water-tight radio box when operating R/C Model boats.
• If you have little to no experience operating R/C Models, we recommend you seek the assistance of an experienced modeler
or your local hobby shop for guidance.
• The Low Voltage Alert alarm will sound when the transmitter battery voltage drops to the default threshold of 4.6 volts. If this
occurs, stop using the transmitter as soon as is safely possible, then replace or recharge the transmitter batteries.
This radio control system operates on the 2.4GHz frequency band. The 2.4GHz connection is determined by the transmitter
and receiver pair. Unlike ordinary crystal-based systems, your Model can be used without frequency control.

GENERAL
2.4GHZ FREqUENCY bAND pRECAUTIONS
• The 2.4GHz frequency band may be used by other devices, or other devices in the immediate area may cause interference on
the same frequency band. Always before use, conduct a bench test to ensure that the servos operate properly. Also, conduct
checks with the transmitter as distant as possible from your Model.
• The response speed of the receiver can be affected if used where multiple 2.4GHz transmitters are being used, therefore,
carefully check the area before use. If response seems slow during use, stop your Model immediately and discontinue use.
• If the 2.4GHz frequency band is saturated (too many transmitters turned ON at once), as a safety precaution, the transmitter
and receiver may not Bind. This ensures that your radio control system does not get hit by interference. Once the frequencies
have been cleared, or the saturation level has dropped, your transmitter and receiver should Bind without any problems.
GENERAL
TRANSMITTER pRECAUTIONS
• To prevent possible damage to your servos or a runaway Model, turn the transmitter ON first,
then turn the receiver ON. After running your Model, turn the receiver OFF first, then turn the
transmitter OFF.
• Before use, double-check that the transmitter and receiver batteries have sufficient
power.
• The transmitter antenna is mounted internally and is located in the vertical back portion of the carrying handle. Do
NOT cover the carrying handle in any way during use! Doing so can block the RF signal, resulting in loss of control
of your Model.
• During use, hold the transmitter so that its orientated as close to vertical as possible at all times. This provides the best RF
signal between the transmitter and the receiver. Try not to ever 'follow' your Model with the transmitter, as
this can result in a weakened RF signal.
• Do not expose the transmitter or any other components to excessive heat, moisture,
fuel, exhaust residue, etc.
• If the outer case becomes dirty, it can be cleaned with a soft dry cloth. If the outer case becomes
soiled, it can be cleaned with a damp cloth and liquid detergent.
• Do not use any solvents to clean the outer case. Solvents will damage the finish.
RECEIvER pRECAUTIONS
GENERAL
• The antenna consists of a coaxial cable and a reception wire (the thin tip at the end of the coaxial cable). When you mount the
antenna, do not bend the reception wire. Reception performance decreases if the reception wire is bent.
• The antenna is delicate, therefore, handle with care. Do not pull on the antenna with force. Do not
cut or extend the antenna.
• The coaxial cable (the thicker portion of the antenna) can be bent into gentle curves, however, do
not bend the coaxial cable acutely, or repeatedly bend it, or the antenna core can be damaged.
• The antenna should be installed into a vertical plastic tube per your particular Model's assembly instructions. Keep the receiver
antenna as far away from the motor, battery and ESC as possible.
• There is a danger of runaway operation if connectors shake loose during use. Make sure that the receiver, servo(s) and switch
connectors are securely fitted.
• The receiver is susceptible to vibration, shock and moisture. Take appropriate measures to protect against vibration and
moisture. Failure to take appropriate measures could result in runaway operation or damage to the receiver. We suggest
wrapping the receiver in shock-absorbing foam or securing it with double-sided foam tape when installing it into your Model.
• When routing the antenna, avoid contact with any carbon or metal chassis components. Contact between metal or carbon
parts can result in electrical noise, which can adversely effect receiver performance and possibly result in runaway operation
and result in damage to your Model.
• With electric-powered Models, be sure to fit any brushed motors with a noise suppression capacitor. Without a noise suppression
capacitor, excessive electrical noise generation can cause runaway operation and result in damage to your Model.
SERvO CONNECTORS
GENERAL
The receiver uses Airtronics 'Z' connectors, which are electronically compatible with the servos of other radio control system
manufacturers. The connectors are rugged, but should be handled with care.
- = Negative (Black)
+ = Positive (Red)
S = Signal (Blue)
If using another brand of servo, double-check the polarity
of the servo connector prior to plugging it into the receiver.
When unplugging the servo connector, don't pull on the servo wire itself. This could result in damage to the servo wire pins
in the plastic plug. Always grasp the plastic connector itself.

M12 2.4GHZ FH4T RADIO CONTROL SYSTEM USER'S GUIDE
TRANSMITTER bATTERY OpTIONS
GENERAL
The M12 transmitter's Operating Voltage Range is 4.0 ~ 9.6 volts. This allows you to use several different battery options (not
included), depending on your preference.
Alkaline - In the default configuration, the transmitter is designed to be powered using four 'AA' Alkaline batteries. This results
in a transmitter that is lightweight and well-balanced for unmatched comfort.
Ni-Cd/Ni-MH - Rechargeable Ni-Cd or Ni-MH batteries of desired capacity can be used in place of the Alkaline batteries. Using
rechargeable Ni-Cd or Ni-MH batteries is more convenient and cheaper in the long run. The Higher capacity batteries will also
provide longer usage time than most Alkaline batteries.
Li-Po or Li-Fe - A 2 cell Li-Po or Li-Fe battery pack can be used to power the transmitter. These battery packs are popular due
to their light weight and high capacity for long usage time between charges.
Transmitter power output, range and speed are the same, regardless of the battery type used. If using a Li-Po or Li-Fe battery
pack, please read the Warnings if Using a Li-Po or Li-Fe Battery Pack section below.
ALkALINE bATTERY INSTALLATION
GENERAL
1) Remove the battery cover from the bottom of the transmitter by pushing firmly on the battery cover in the direction of the arrow.
2) Install four fresh 'AA' Alkaline batteries into the
battery holder, making sure that the polarity is
correct. The direction that each battery should be
installed is molded into the bottom of the battery
holder (+ Positive and - Negative).
3) Slide the battery cover back onto the transmitter and push it firmly until it 'clicks' closed.
When installing the batteries, remove the battery holder and double-check that the battery holder is plugged in. If it isn't, plug
the connector on the battery holder into the matching connector in the transmitter.
TRANSMITTER bATTERY CHARGING OpTIONS
GENERAL
The M12 transmitter features a Charge Jack that can be used with the Airtronics 95034 Dual Output charger (available separately)
to charge the optional Ni-Cd or Ni-MH batteries. This allows you to charge these batteries without removing them from the
transmitter. A Charge Jack is located on the Left side of the transmitter. For more information, see the Transmitter Overview
Diagrams section on page 7.
WARNING: Do NOT attempt to recharge Alkaline batteries. Only Ni-Cd or Ni-MH batteries should be charged through the
transmitter's Charge Jack, using only the Airtronics 95034 Dual Output charger or equivalent overnight/slow charger. Do NOT
attempt to charge a Li-Po or Li-Fe battery pack through the Charge Jack.
Do NOT use the Charge Jack with a fast charger or a peak-detection charger, or the transmitter could be damaged!
If you use a fast charger or a peak-detection charger to charge the transmitter batteries, the battery holder must be removed
from the transmitter first. The circuitry within the transmitter will interfere with the peak-detection charger's normal operation,
resulting in over-charging and damaging the batteries and possibly the transmitter itself. In addition, the Higher charge rate
common in many fast chargers can damage the transmitter's circuitry.
Damage caused by fast-charging through the transmitter or using an incorrect battery type will not be covered under warranty!
wARNINGS IF USING A LI-pO OR LI-FE bATTERY pACk
GENERAL
• Use ONLY a 2 Cell Li-Po or Li-Fe battery pack of desired capacity.
• Do NOT charge your Li-Po or Li-Fe battery pack through the Charge Jack. The battery pack MUST be removed from the
transmitter prior to charging or the transmitter could be damaged. For more information, see the WARNING in the Transmitter
Battery Charging Options section above.
• Use a charger specifically designed to charge Li-Po or Li-Fe battery packs.
• When changing the connector on your battery pack to match the battery connector in the transmitter,
please observe correct polarity. Connecting with reverse polarity will damage the transmitter.
- = Negative (Black)
+ = Positive (Red)
• Observe all safety precautions provided with your Li-Po or Li-Fe battery pack.
• Damage to the transmitter caused by improper use, wrong battery type, incorrect voltage, reverse polarity or charging
through the Charge Jack will not be covered under warranty!
The transmitter has a Nominal Input Voltage range of 4.8 ~ 7.4 volts. DO NOT USE A 3 CELL Li-Po or Li-Fe battery pack or
the transmitter will be damaged!

TRANSMITTER AND RECEIvER bINDING
GENERAL
The Binding function allows you to Bind the transmitter and receiver pair. When new, it is necessary to pair the transmitter and
receiver to prevent interference from transmitters operated by other users. This operation is referred to as 'Binding'. Once the
Binding procedure is complete, the setting is remembered even when the transmitter and receiver are turned OFF, therefore, this
procedure usually only needs to be done once.
The M12 transmitter features a Safety Link function that is used to program a unique code to each receiver/Model pair,
preventing the transmitter from controlling a Model that it's not currently programmed for. The Safety Link function is
compatible only with FH4 or FH4T receivers. It's not compatible with FH2 or FH3 receivers.
IMPORTANT: This section details Binding the RX-471 FH4 Super Response receiver with a Safety Link Model number of 1 and
with the Servo Operating Mode set to Normal mode. If you are Binding an FH2 or FH3 receiver, or if you prefer to change the
Safety Link Number or the Servo Operating Mode, see the BIND Menu section on pages 30 ~ 32.
Before beginning the Binding procedure, connect the switch harness, servos and the receiver battery to your receiver,
using the diagram in the Receiver Overview Diagram, Connections and Mounting section on page 8. Make sure that both
the transmitter and the receiver are turned OFF.
1) Turn the transmitter ON. The STATUS screen should be displayed.
2) Press the SELECT switch to highlight the SYSTEM menu, then press the ENTER
key to open the SYSTEM menu.
3) Scroll UP or DOWN to highlight the BIND menu, then press the ENTER key to
open the BIND menu.
Double-check that the Modulation is set to FH4T, Telemetry is turned ON, Safety Link is set to 01 and CH1, CH2, CH3 and
CH4 are each set to NOR. If you want to change any of these settings, see the BIND Menu section on pages 30 ~ 32.
4) While holding down the Bind Button on the receiver, turn the receiver ON. The
Bind LED on the receiver will flash slowly. Release the Bind Button. The Bind
LED on the receiver will continue to flash slowly.
You must complete step 5 below within 10 seconds or the Bind LED will go out, indicating the receiver has timed out. If this
occurs, turn the receiver OFF, then repeat step 4.
5) Scroll DOWN to highlight the BIND [ENTER] option, then press the ENTER key.
The [ENTER] command and LED1 on the transmitter will begin to flash and
the Bind LED on the receiver will flash rapidly, then go out.
6) After the Bind LED on the receiver goes out, press the ENTER key a second time. Both the Bind LED on the receiver and LED1 on
transmitter will illuminate solid blue, indicating that the Binding procedure is complete.
7) Move the Steering Wheel and Throttle Trigger to verify that the servos are operating normally, then repeatedly press the
BACK key to return to the STATUS screen.
Under some circumstances, the receiver may not operate after turning the transmitter and receiver ON. If this occurs,
perform the Binding procedure again.

Changing the Servo Operating Mode:
The Servo Operating Mode function is used to optimize the radio control system to suit the type of servos you're using in your
Model. For example, using the SHR setting with Digital servos will Increase the servo's response time, even above the
manufacturer's stated specification. If you're using Airtronics SRG Digital servos, you can use the SSR setting for the fastest
response time. The combination of using Digital servos and using the correct Servo Operating Mode value results in the ultimate
feel and response, making you feel more in control of your Model than ever.

IMPORTANT INFORMATION ABOUT SERVO OPERATING MODE VALUES:
If you're using Analog servos in your Model, DO NOT use SHR or SSR Servo Operating Mode values for those channels. Use
the NOR (Normal) Servo Operating Mode with Analog servos. Using SHR or SSR Servo Operating Mode values with Analog
servos can result in poor performance or even damage to the servos or the receiver!
Not all ESCs are compatible with SHR or SSR Servo Operating Modes. If your ESC does not operate correctly, change the Servo
Operating Mode to NOR (Normal) for that channel (or channels).
SHR and SSR Servo Operating Modes should only be used with Digital servos. While the SHR Servo Operating Mode can be
used with any brand of Digital servo, the SSR Servo Operating Mode should ONLY be used with Airtronics SRG Digital servos.

TRIM TYpE MENU {SERvO TRIM TYpE}
SYSTEM
The Trim Type function allows you choose the way servo Trim and servo End Point Adjustments interact with each other. When
you apply Trim to a servo, the Neutral Point of the servo shifts toward the High Side or the Low Side. When you do this, the servo
travels less in one direction and more in the other direction because the servo End Points are stationary. In order to balance the
servo travel, you would need to manually readjust the servo End Points. Using the Trim Type function allows you to make the servo
End Points shift toward the High Side or the Low Side when you apply Trim. This maintains balanced servo travel without the need
to manually readjust the servo End Points.
The Trim Type function does not effect servo Sub-Trim. It only effects servo Trim that's input using the Trim Switches, Auxiliary
Dial or Auxiliary Lever. Servo Sub-Trim, which is different, always uses Parallel Trim.
Two Trim Types are available:
CENTER - When Selected, servo End Points are stationary. In order to balance servo travel, you would need to
manually readjust the servo End Points, if desired.
PARALLEL - When Selected, servo End Points shift toward the High Side or the Low Side automatically
when you apply Trim. This maintains balanced servo travel without the need to manually readjust the
servo End Points.
Changing the Trim Type:
1) From within the SYSTEM menu, scroll UP or DOWN to highlight the TRIM TYPE
menu.
2) Press the ENTER key to open the TRIM TYPE menu. ST > CENT will be highlighted.

TH TYpE MENU {THROTTLE bIAS RATIO}
SYSTEM
The Throttle Type function allows you to change the ratio between Throttle High Side servo travel and Throttle Brake Side servo
travel. In the default configuration, the Throttle Type is set to F70:B30. This Throttle Type shifts the Throttle Neutral Point toward the
Brake Side, resulting in more servo travel toward the High Side and less servo travel toward the Brake Side.
Some users may prefer the ratio between Throttle High Side servo travel and Throttle Brake Side servo travel to be balanced
(F50:B50) so that servo travel is equal. The F70:B30 Throttle Type is most common for general use and racing, while the F50:B50
Throttle Type is most common for Rock Crawling.

Calibrating the RPM Sensor - Changing the Ratio Value, Continued....
The Ratio value is the gear ratio between the two gears that the RPM sensor is mounted to. For example, if the RPM sensor is
mounted to your spur gear, the Ratio value will be the gear ratio of your spur gear and pinion gear.
IMPORTANT: To calculate the gear ratio, divide the number of teeth in the spur gear by the number of teeth in the pinion gear.
For example, if your spur gear is 60T and your pinion gear is 14T, the gear ratio is 60 / 14 = 4.28.

ratio value. Press the ENTER key, then scroll UP or DOWN to choose the
desired third Ratio value.
RATIO setting range is 1.000 to 64.999. The default setting is 1.000.
If the RPM sensor is mounted to your engine's flywheel or your motor's pinion gear to read the RPM directly, the Ratio value
should be set to 1.000.
Calibrating the RPM Sensor - Changing the 10Count Distance Value:
The 10Count Distance value can be changed if you've Selected UNIT > MPH or UNIT > KM/H. By changing the 10Count Distance
value you are able to calibrate the RPM sensor to read your specific Model's actual speed, in either MPH or KM/H.
Prior to calibrating the RPM sensor, you must connect the RPM sensor to your receiver and correctly install the RPM sensor
into your Model. For more information, see the Telemetry Connections and Mounting section on pages 96 ~ 97.
1) With your transmitter and receiver turned ON, and with an Active Telemetry connection, place your Model on the ground.
2) Measuring in inches (or centimeters if using KM/H) from where you set your Model on the ground, slowly push your Model
and measure the distance covered to complete 10 full revolutions of the RPM sensor (the Bind LED on your receiver will flash
10 times, indicating 10 full revolutions).
3) From within the RPM menu and with UNIT > MPH or UNIT > KM/H Selected,
scroll UP or DOWN to highlight 10COUNT DIST > 12.0 or 10COUNT DIST > 30,
depending on the UNIT > value Selected previously.
4) Press the ENTER key, then scroll UP or DOWN to change the 10Count Distance
value to match the measurement obtained in step 2 above. For example, if
your Model traveled 2 feet (61cm) to complete 10 full revolutions, enter 24.0
(for MPH) or 61 (for KM/H).
10COUNT DIST setting range is 0.5 to 118.0 for MPH and 1 to 300 for KM/H. The
default setting is 12.0 for MPH and 30 for KH/H.
IMPORTANT: Changing the 10Count Distance value will change the Maximum Scale value. After calibration, you should reset
the Maximum Scale value back to the value you chose previously.

EpA MENU {CHANNEL END pOINT ADjUSTMENTS}
SETUp
The End Point Adjustment function allows you to adjust servo travel in each direction. This makes it possible to balance servo
travel in both directions and set the maximum desired amount of servo travel. For example, on a gas-powered Model, if you pull
the Throttle Trigger and the carburetor does not open completely, you can Increase the Throttle High End Point Adjustment so
that the carburetor opens completely. Another example is with Steering. If your Model turns sharper to the Right than to the Left,
you can Increase the Steering Left End Point Adjustment to balance the Steering.
The End Point Adjustment function can be adjusted for the Steering channel (Right and Left), the Throttle channel (High and
Brake), the Auxiliary 1 channel (High and Low) and the Auxiliary 2 channel (High and Low).
Before making End Point Adjustments, the servo horn needs to be centered. Install the servo horn onto the servo, making
sure it's as close to being centered as possible, then use the Servo Sub-Trim function to center the servo arm exactly. For
more information, see the SUB TRIM Menu section on page 63.
End Point Adjustment percentage values should not be increased to the point where your
linkages and servos Bind when moved all the way to the Right or Left. Binding will cause
the servos to 'buzz', resulting in a quicker loss of receiver battery power and eventual damage to
the servos or to your Model.
Changing the Channel End Point Adjustment Percentage Values:
1) From within the SETUP menu, scroll UP or DOWN to highlight the EPA menu.
2) Press the ENTER key to open the EPA menu. The cursor will default to either
ST > L100% or ST > R100%.
3) Scroll UP or DOWN to highlight the desired End Point Adjustment percentage
value you would like to change.
4) Press the ENTER key, then scroll UP or DOWN to Increase or Decrease the
End Point Adjustment percentage value. Increasing the percentage value will
Increase servo travel in that direction and Decreasing the percentage value
will Decrease servo travel in the that direction.
5) Press the ENTER key, then repeat steps 3 and 4 to change any other desired
End Point Adjustment percentage values.
ST L and R setting range is 0% to 150%, TH H and B setting range is 0% to 150%, AUX1 H and L setting range is 0% to 150%
and AUX2 H and L setting range is 0% to 150%. The default setting for all channels is 100%.
If you're using an Electronic Speed Control, the Throttle High and the Throttle Brake End Point Adjustment percentage
values are both generally set to 100%, although the Throttle High direction may need to be increased to achieve full power.
In some cases, Throttle and Brake End Point Adjustments can also be set directly via the Electronic Speed Control.

SUb TRIM MENU {SERvO CENTERING}
SETUp
The Sub-Trim function allows you to correct the Neutral Trim setting for the Steering, Throttle, Auxiliary 1 and Auxiliary 2 channels,
making it possible to center the Trim Switches while ensuring the servo horns remain centered.
It's not unusual that when you center a servo and install the servo horn, the servo horn is not exactly centered. The Sub-Trim
function allows you to center the servo horn exactly, without altering the servo End Point travel. This is especially useful
when using a Mix, such as Four Wheel Steering Mixing. For example, you can use the Sub-Trim function to adjust the Neutral
Trim setting of your Front and Rear Steering servos independently to ensure your Model tracks straight.
Before changing the Sub-Trim values you should set the Steering and
Throttle Trim to 0% using the Trm1 and Trm2 Trim Switches.
Changing the Servo Sub-Trim Values:
1) Install the servo horn (or servo saver for the Steering servo) onto your servo,
making sure that the servo horn (or servo saver) is as close to being centered
as possible. In some cases, you can get the servo horn closer to being
centered by rotating the servo horn 180º and reinstalling it.
2) From within the SETUP menu, scroll UP or DOWN to highlight the SUB TRIM
menu.
3) Press the ENTER key to open the SUB TRIM menu. The cursor will default to
ST > 0.
4) Scroll UP or DOWN to highlight the desired Sub-Trim value you would like to
change.
5) Press the ENTER key, then scroll UP or DOWN to Increase or Decrease the
Sub-Trim value only enough to center the servo horn.
6) Press the ENTER key, then repeat steps 4 and 5 to change any other desired
Sub-Trim values.
ST setting range is R150 to L150, TH setting range is H150 to B150, AUX1 setting range is H150 to L150 and AUX2 setting range
is H150 to L150. The default setting for all channels is 0.
IMPORTANT: Changing the Sub-Trim values will alter the servo's End Points. After changing the Sub-Trim values, use the End
Point Adjustment function to Reset the servo End Point Adjustment Percentage Values. For more information, see the Changing
the Channel End Point Adjustment Percentage Values section on the previous page.
