This is a high-output full-range radio control system that should well exceed the range needed for any surface vehicle. 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 vehicle a the farthest reaches of the operational area. Rather than operating the vehicle, we recommend that the user
enlist the help of a fellow modeler to walk the vehicle 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.

usage precautions
TRANSMITTER PRECAUTIONS
In addition to the Safety and FCC Compliance sections on the previous page, please observe the following precautions when
installing and using your new Airtronics M11X FHSS-3 2.4GHz radio control system.
lThe receiver antenna consists of a coaxial cable and a reception wire (the thin tip at the end of the coaxial cable). When you
mount the receiver antenna, do not bend the reception wire. Reception performance decreases if the reception wire is bent.
lThe antenna wire is delicate, therefore, handle with care. Do not pull on the antenna wire with force. Do not cut or extend the
antenna wire.
lThe coaxial cable (the thicker portion or 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.
lThe antenna wire 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.
lThere is a danger of runaway operation if connectors shake loose during use. Make sure that the receiver, servo(s), and switch
connectors are securely tted.
lThe 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.
lWhen installing the receiver, avoid contact with any carbon or metal chassis components.
lContact between metal parts mounted on a model can result in electrical noise, which can adversely effect receiver performance
and possibly result in runaway operation or damage to your model.
l With electric-powered models, be sure to t the motor with a noise suppression capacitor. Without a noise suppression capacitor,
excessive electrical noise generation can cause runaway operation and/or result in damage to your model.
lUse rubber anti-vibration absorbers with servos. Direct transmission of engine vibration to servos can cause servo failure and
possibly result in runaway operation with damage to your model.
lThe manufacturer disclaims all responsibility for damages resulting from use of components other than genuine Airtronics
components.
lTurn the transmitter ON rst and then turn the receiver ON. After using your model, turn the receiver OFF rst, then turn the
transmitter OFF. It can be dangerous if you activate the components in reverse order as the servos may start up inadvertently.
lBefore use, double-check that the transmitter and receiver batteries are sufciently charged.
lNever touch the transmitter antenna during use. Doing so may cause loss of transmitter output, making it impossible to control
your model.
lThe transmitter's antenna is delicate. Handle it with care.
lBefore use, the transmitter antenna should be moved in the fully upright position. After use, to prevent any chance of damaging
the antenna, the antenna should be moved into the horizontal stowed position.
lDo not press the Bind key during use. The radio signal is interrupted while the Bind key is pressed. It may also require a short
time to restore the signal after releasing the Bind key, which can be dangerous.
RECEIVER PRECAUTIONS
2.4GHZ FREQUENCY BAND PRECAUTIONS
lThe 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.
lThe response speed of the receiver can be affected if used where multiple 2.4GHz radio controllers are being used, therefore,
carefully check the area before use. Also, if response seems slow during use, stop your model immediately and discontinue use.
lIf the 2.4GHz frequency band is saturated (too many radio controllers on at once), as a safety precaution, the radio control
system 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 radio control system should be able to bind without any problems.

Charging the battery
SAFETY PRECAUTIONS AND CHARGING WARNINGS
The M11X FHSS-3 2.4GHz transmitter features a 6 cell 7.2v 1500mAH NiMH battery for lighter weight and longer battery life.
The battery is charged directly through the transmitter, using the charging jack located at the base of the grip. Please observe the
Safety Precautions and Charging Warnings below when charging the transmitter battery.
lAlways follow the charging procedures described below to ensure safe and correct use of your NiMH battery.
lThe NiMH battery is not charged when purchased. It is necessary to charge the NiMH battery before operation.
lBefore charging the NiMH battery, double-check that the transmitter power switch is in the OFF position.
lOvercharging reduces the life of the battery and can result in electrolyte spills, overheating, and bursting. This may cause
personal injury and/or property damage.
lDo not plug the charger into anything other than an AC 110v power outlet. Plugging the charger into anything other than
AC 110v outlet may result in smoking, sparks, or re.
l Do not throw the NiMH battery or abuse it in any manner. Do not dispose of the NiMH battery in the re or allow it to overheat.
lDo not short-circuit the NiMH battery terminals with wire or any other object.
USING A TRANSMITTER LIPO BATTERY
An after-market Li-Po battery can be used in place of the stock 6 Cell 7.2v 1500mAH NiMH transmitter battery. If you decide to
replace the stock battery with a Li-Po battery, please observe the following:
lUse ONLY a 2 Cell 7.4v Li-Po battery of desired capacity. DO NOT USE A 3 CELL 11.1V LI-PO BATTERY.
lYou MUST remove the battery from the transmitter to charge the battery.
lDo NOT use the charger included with the transmitter to charge a Li-Po battery. You MUST use a dedicated Li-Po battery
charger.
lWhen you change the connector on your Li-Po battery, please observe correct polarity.
CHARGING THE TRANSMITTER BATTERY
An after-market peak-detection charger can be used to charge the NiMH transmitter battery, however, the battery must
rst be removed from the transmitter to be charged. The circuitry within the transmitter will interfere with the peak-detection
charger's normal operation, resulting in over-charging and damaging the battery and possibly the transmitter itself.
1) Plug the round connector from the charger into the charging
jack in the grip of the transmitter.
2) Plug the supplied charger into a 110v AC wall socket. The
charger LED will illuminate red indicating that the charger
is plugged in and charging.
3) Transmitter charger output is 150mAH, therefore, it will take
approximately 10 hours to recharge a fully-discharged
battery. We suggest leaving the charger on overnight.

transmitter and receiver binding
When new, it is necessary to pair the transmitter and receiver to prevent interference from radio controllers operated by other
users. This operation is referred to as 'binding'. Once the binding process 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. Under some circumstances,
the receiver may not operate after turning the transmitter and receiver ON. If this occurs, perform the binding process again.
1) Turn on the transmitter, then press the two Function keys at the same
time until Function Menu F3 is displayed. If the SET-UP menu is not
automatically highlighted, continue to press the Function key until the

steering Dual rate
Function Page 1 (D-RATE)
The Steering Dual Rate function is used to change the amount of steering servo travel compared to the amount of movement of
the steering wheel. For example, by increasing the Steering Dual Rate, you can make the steering servo travel more which might
prevent your model from pushing during turns. If your model oversteers during turns, you can reduce the amount of Steering
Dual Rate.
2) Press the Function key to highlight the D-RATE menu. DUAL-RATE will
be active in the Programming Window. As you move the steering wheel
right and left, you can set the bar graph move to the dual rate limit lines.
To adjust the Dual Rate, press the INC/+ or DEC/- keys to increase or
decrease the Dual Rate amount. At this time, set the dual rate to 125%.
This will increase the servo movement by 25% in both left and right
directions.
5) After the Dual Rate has been set, adjust the independent
left and right End Points using the EPA feature. See the next
page for information on setting the EPA.
1) Set the digital steering trim to '0' using the Trm 1 switch. You can see when the trim reaches
'0' by viewing either of the two trim screens (ST) and/or (TRM-S).
3) Attach the steering linkage to the servo arm per your model's assembly manual.
Pressing both the INC/+ and DEC/- keys at the same time will set the
Dual Rate to the default setting.
Steering Trim

Trm 1 Switch
4) Move the steering wheel right and left to full. If your steering binds at both
ends, this means that you have too much steering servo movement.
Adjust the Dual Rate to decrease (DEC/-) or increase (INC/+) the amount
of steering to reach the steering stops.
Before adjusting the Steering Dual Rate you should adjust the steering
linkage so that when the steering trim is centered, the servo arm is
centered on the servo and both wheels are pointing straight ahead. Doing so
will prevent a lot of steering problems in the future.

end point adjustment
Function Page 1 (EPA)
The End Point Adjustment function is used to adjust the desired amount of servo travel in both the right and left directions
independently. EPA can be set for the Steering channel, Throttle channel, Auxiliary channel, and Brake channel (4CH Mode).
In the default conguration (FH3 Modulation), the transmitter is set to 4CH Mode. If you are using FH2 Modulation with a
legacy FHSS-2 receiver, the default conguration is 2CH Mode. To enable 4CH Mode, see page 47 for more information.
[ST]STEERING END POINT ADJUSTMENT
Your model’s turning radius can differ from left to right because of variations in linkage, suspension balance, tire diameter, or
weight distribution. In such cases, the left and right servo steering angle is adjustable.
Before making the End Point Adjustment, you must center the servo horn. To center the servo horn, adjust the servo horn
on the servo so that it is as close to center as possible, then make ne-tuned adjustments to exactly center the servo horn,
using the Sub-Trim function. See page 33 for more information.
EPA ST setting range is between 0% and 150% in either direction. The default setting is 100%.
Setting the Steering Dual Rate and Steering End Points excessively high may cause a dead point on the servo, resulting
in improper operation or servo failure. When set correctly, the servo should not buzz at full travel.
[TH]THROTTLE END POINT ADJUSTMENT
Your model's carburetor may not open completely, or opens too much and causes the servo to bind. If you're using an ESC, the
ESC may not command full power, or the brake may not engage adequately. In such cases, the throttle high and low points and
the brake is adjustable.
1) Press the Function key to move the cursor to [TH] in the EPA Programming
Window.
2) To adjust the throttle side, pull the throttle trigger back. The cursor will
move next to 100%H. Press the INC/+ or DEC/- keys to increase or
decrease the amount of servo travel. To adjust the brake side, push the
throttle trigger forward. The cursor will move next to 100%B. Press the
INC/+ or DEC/- keys to increase or decrease the amount of servo travel.
EPA TH setting range is between 0% and 140% in the H (throttle) position and anywhere between 0% and 160% in the B (brake)
position. The default setting is 100% in both directions.
With an ESC, the throttle and brake are both ordinarily set to 100% and
are typically set on the ESC.
1) Press the Function key to highlight the EPA menu. [ST] will be active in
the Programming Window and the cursor will default to 100%L.
2) To set right Steering EPA, turn the steering wheel to the right. The cursor
will move next to 100%R. Press the INC/+ or DEC/- keys to increase
or decrease the amount of servo travel in the right direction. To set left
Steering EPA, turn the steering wheel to the left. The cursor will move
next to 100%L. Press the INC/+ or DEC/- keys to increase or decrease
the amount of servo travel in the left direction.
