SAfETY
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 Alarm will sound when the transmitter battery voltage drops to the minimum threshold of 4.6 volts. If this
occurs, stop using the transmitter as soon as is safely possible, then replace 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.

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 radio controllers 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 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.
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 features an internal antenna installed inside the front portion of the transmitter.
Do NOT cover the front of the transmitter 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.
• Do not press the Bind Button during use. The signal is interrupted while the Bind
Button is pressed. It may also require a short time to restore the signal after
releasing the Bind Button, which can be dangerous.
• 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
• The antenna wire is delicate, therefore, handle with care. Do not pull on the antenna wire with force.
• Do not cut the antenna wire shorter or extend the antenna wire.
• The antenna wire can be bent into gentle curves, however, do not bend it acutely, or repeatedly bend it, or the antenna wire
can be damaged.
• The 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.
• 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 installing the receiver and routing the receiver antenna, avoid contact with any carbon or metal chassis components.
Contact 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.
• 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/or result in damage to your model.
• The receiver does not feature BEC circuitry. If using an electronic speed control, verify that it features BEC circuitry to drop
the receiver voltage between 4.8v to 7.4v.
SERVO CONNECTORS
The receiver included with your radio control system 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.

TRANSMITTER bATTERY RECOMMENDATIONS
The 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 capa city 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 battery pack or a 2 cell 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.
Rechargeable batteries will need to be charged with a dedicated charger outside of the transmitter. Transmitter power
output, range and speed are the same, regardless of the battery voltage and type used. If using a Li-Po or Li-Fe battery pack,
please obverse the warnings in the Battery Installation section on page 7.

TRANSMITTER AND RECEIVER bINDING
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 radio controllers 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. Bind codes are unique to each transmitter and receiver pair, so you can bind
multiple receivers to the same transmitter.
Before beginning the binding procedure, connect the switch harness, servos and the receiver battery to your receiver, using
the diagram on page 8. Make sure that both the transmitter and the receiver are turned OFF.
The transmitter is compatible with FH2 receivers, however, the transmitter is also
compatible with FH2F and DS2 receivers. To bind the transmitter to an FH2F or DS2
receiver (not common in North America), the transmitter Modulation Type must first be
changed. For more information, see the Modulation Type section on page 18.
1) Turn the transmitter ON. The Power Indicator on the transmitter will illuminate red.
2) 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 3 below within 10 seconds after pressing the Bind
Button on the receiver or you will need to start the binding procedure over.
3) Quickly press the Bind Button on the transmitter. The Bind LED on the receiver will flash
rapidly, go out momentarily, then illuminate solid blue, indicating the binding procedure
is complete.
When the binding procedure is successful, the Bind LED on the receiver will stay solid blue when both the transmitter and
receiver are turned ON. If the Bind LED on the receiver is flashing rapidly or not illuminated at all, the transmitter and receiver
are not paired. In this case, turn both the transmitter and receiver OFF, then repeat the binding procedure again.
Under some circumstances, the receiver may not operate after turning the transmitter and receiver ON. If this occurs,
perform the binding procedure again.

MX-V 3-CHANNEL 2.4GHZ RADIO SYSTEM USER'S GUIDE
THROTTLE fAIL SAfE PROGRAMMING
The Throttle Fail Safe function automatically moves the throttle servo to a predetermined position in the event that the signal
between the transmitter and the receiver is interrupted, whether due to signal degradation or to low transmitter battery voltage.
For example, the Throttle Fail Safe function can be set so that the throttle returns to idle or the brake engages so that your model
doesn't run away if the signal is lost.
The Throttle Fail Safe function will not operate if the receiver loses power, for example, if the receiver battery comes loose
or if the receiver battery is drained.
Setting the Throttle Fail Safe Position:
1) Turn the transmitter ON, then turn the receiver ON. The Power Indicator on the transmitter should be illuminated and the Bind
LED on the receiver should also be illuminated.
2) Move the transmitter steering wheel and throttle trigger to verify correct servo movement.
3) Move the throttle trigger to the desired Throttle Fail Safe position. While holding the throttle trigger in the desired position, press
and HOLD the Bind Button on the receiver. After approximately 2 seconds, the Bind LED will begin to flash slowly. Continue

D/R - DUAL RATE
The Dual Rate function allows you to change the control authority of your model's steering by changing the amount of servo
travel relative to control input. For example, by increasing the 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 Dual Rate.
IMPORTANT: Prior to programming the Dual Rate function, you should adjust the Left and Right Steering End Points, using the
End Point Adjustment function. For more information, see the End Point Adjustment section below.
Adjusting the Steering Dual Rate Percentage Value:
1) Press the MENU UP or MENU DOWN keys to open the D/R menu. D/R will flash
and ST 100% will be displayed.
2) Press the INCREASE or DECREASE keys to change the Steering Dual Rate
percentage value. When the Steering Dual Rate percentage value is decreased,
steering servo travel is decreased. When the Steering Dual Rate percentage value
is increased, steering servo travel is increased.
D/R ST setting range is 0% to 100%. The default setting is 100%.
Dual Rate is a percentage of End Point Adjustment. For example, if you set the Steering Dual Rate percentage value to
100%, the steering will travel the same amount as defined by your Steering End Point Adjustment programming. If you
set the Steering Dual Rate percentage value to 50%, the steering will travel half that amount.
3) Steering Dual Rate can be adjusted at any time while driving using the Dual Rate
Switch. Press the Dual Rate Switch forward to increase the Steering Dual Rate
percentage value and press the Dual Rate Switch backward to decrease the
Steering Dual Rate percentage value.
EPA - END POINT ADjUSTMENT
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 Forward 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 (Left and Right), the Throttle channel (Forward and
Brake) and Auxiliary Channel 3 (High and Low).
Throttle
Steering
If you're using an electronic speed control, the
Throttle Forward and the Throttle Brake End Point
Adjustment percentage values are both generally set to
100%, although the Throttle Forward direction may need
to be increased to achieve full power. In some cases the
End Point Adjustments can also be set directly via the
electronic speed control.
WARNING: End Point Adjustment percentage values should not be increased to the point where your linkages and/or servos
bind when moved all the way in either direction. Binding will cause the servos to 'buzz', draining the receiver battery quickly
and eventually damaging the servos.
Before making End Point Adjustments, the servo horns need to be centered. Install the servo horns onto the servos, making
sure that they're as close to being centered as possible, then use the Servo Sub-Trim function to center the servo arms
exactly. For more information, see the Servo Sub-Trim section on page 16.

EPA - END POINT ADjUSTMENT
Adjusting the Auxiliary Channel 3 End Point Adjustment Percentage Values:
Auxiliary Channel 3 can be used for a number of different uses. One of the more common uses would be for the reverse function
in a glow-powered monster truck. Often, the transmission only requires a small amount of travel, but the servo binds because
of too much servo travel. In such a case, Auxiliary High servo travel and Auxiliary Low servo travel are adjustable using the End
Point Adjustment function.
1) From within the EPA menu, press the MENU UP or MENU DOWN keys to display
AUX H or AUX L 100%.
2) Push the Auxiliary Lever down. AUX L should be displayed. Press the INCREASE or
DECREASE keys to increase or decrease the Auxiliary Low End Point Adjustment
percentage value. Increasing the percentage value will increase
auxiliary servo travel in that direction and decreasing the percentage
value will decrease auxiliary servo travel in the that direction.
EPA AUX L setting range is 0% to 150%. The default setting is 100%.
3) Push the Auxiliary Lever up. AUX H should be displayed. Press the INCREASE or
DECREASE keys to increase or decrease the Auxiliary Low End Point Adjustment
percentage value. Increasing the percentage value will increase
auxiliary servo travel in that direction and decreasing the percentage
value will decrease auxiliary servo travel in the that direction.
EPA AUX H setting range is 0% to 150%. The default setting is 100%.
EXP - EXPONENTIAL
The Exponential function allows you to vary the amount of servo travel in relation to the movement of the steering wheel and
throttle trigger near the Neutral positions to change the way those functions react to control movement. Decreasing the Exponential
percentage values will soften the control feel around Neutral and increasing the Exponential percentage values will heighten the
control feel around Neutral. Using a lower negative value allows for smoother control. Using a higher positive value may result
in more 'twitchy' control response.
The Exponential function can be adjusted for the Steering channel and the Throttle channel.
Adjusting the Steering Exponential Percentage Value:
Steering Exponential can be variably adjusted from Mild through Linear to Quick to allow you to set the most effective steering
response for your model. Generally, if your model over-steers, reduce the Exponential percentage value, and if your model
under-steers, increase the Exponential percentage value.
1) Press the MENU UP or MENU DOWN keys to open the EXP menu. EXP will flash
and ST 0% will be displayed.

EXP - EXPONENTIAL
Adjusting the Steering Exponential Percentage Value, Continued:
2) Press the INCREASE or DECREASE keys to change the Steering Exponential
percentage value. Decreasing the Steering Exponential percentage value will make
the steering less sensitive around Neutral and increasing the Steering Exponential
percentage value will make the steering more sensitive around Neutral.
EXP ST setting range is -100% (Mild) to 100% (Quick). The default setting is 0% (Linear).
Changes to the Steering Exponential percentage value affects the Left and Right sides equally.
Adjusting the Throttle Exponential Percentage Value:
Throttle Exponential can be variably adjusted from Mild through Linear to Quick. In general, reduce the Exponential percentage
value on a slippery track or with a model that has a higher-torque motor or engine to help prevent your model from spinning out
during acceleration. Increase the Exponential percentage value on a high-grip track where your model is less likely to spin out, or
with a model that has a lower-torque motor or engine.
1) From within the EXP menu, press the MENU UP or MENU DOWN keys to display
TH 0%.
2) Press the INCREASE or DECREASE keys to change the Throttle Exponential
percentage value. Decreasing the Throttle Exponential percentage value will make
the throttle less sensitive around Neutral and increasing the Throttle Exponential
percentage value will make the throttle more sensitive around Neutral.
EXP TH setting range is -100% (Mild) to 100% (Quick). The default setting is 0%
(Linear).
Changes to the Throttle Exponential percentage value affects the Forward and Brake sides equally.
ALb - ANTI-LOCK bRAKING
The Anti-Lock Braking function makes it possible to achieve stable braking even on a slippery surface. With stable braking, your
model is better able to trace an exact line under braking. When the Anti-Lock Braking function is Active, the throttle servo will pulse
when you apply brake. Three Pulse Rate values are available to suit your particular model, track conditions and driving style.
The Anti-Lock Braking function is primarily used on gasoline or glow (nitro) models that feature a throttle servo. It can be
used on an electric model that uses an electronic speed control, however, if your electronic speed control features a
reverse function, the Anti-Lock Braking function will not operate properly.
Use the fastest Pulse Rate value that allows your model's tires to not
slip and loose traction under the hardest braking. Be aware that using
the Anti-Lock Brake function will never result in your model losing traction
under braking. It only improves braking under less than ideal conditions.
With ABS ON
With ABS OFF
Activating the Anti-Lock Braking Function:
1) Press the MENU UP or MENU DOWN keys to open the ALB menu. ALB will flash
and TH OFF will be displayed.

ALb - ANTI-LOCK bRAKING
Activating the Anti-Lock Braking Function, Continued:
2) Press the INCREASE or DECREASE keys to choose the desired Anti-Lock Braking
Pulse Rate value. The Pulse Rate value determines how fast the throttle servo
pulsates the brake. Experimentation will be necessary to determine which Pulse
Rate value to use.
ALB setting range is OFF, SLW (Slow), NOR (Normal) and FST (Fast). The default setting is OFF.
Due to the nature of the Anti-Lock Braking function, we suggest using a high-quality, strong throttle servo. If your throttle
servo is not strong enough, the Anti-Lock Braking function may not operate optimally.
TRIM - SERVO TRIM
The Servo Trim function allows you to view the currently programmed Servo Trim value for the steering and throttle channels and,
if desired, allows you to change the Trim values from within the TRIM menu, using the programming keys.
The transmitter features Digital Trim Memory. Any amount of Steering or Throttle Trim that you set during use by pressing the Trim
Switches or using the TRIM menu is automatically stored in memory for that specific channel and for that specific Model Number.
The Trim values for each model will automatically be loaded when the transmitter is turned ON.
Before adjusting the Trim values, you should first adjust the servo Sub-Trim values to center the servo horns. For more
information, see the Servo Sub-Trim section on pages 16 and 17.
The Servo Trim function should not be used to center the steering and throttle servos. Use the Servo Sub-Trim function
for that. The Servo Trim function is used to make trim adjustments to your model during use. For example, if your models
always pulls to the left while driving, apply enough Steering Right Trim to make you model drive straight.
Changing the Steering Servo Trim Values:
1) Press the MENU UP or MENU DOWN keys to open the TRIM menu. TRIM will flash
and ST 0 will be displayed.
2) Press the INCREASE or DECREASE keys to adjust the Steering Servo Trim value
either Right or Left. The actual direction will differ based on the steering channel's

The Model Select function allows you to store and retrieve Programming Data for any model 1 through 10. If you're using your
transmitter with more than one model, use the Model Select function to load the Programming Data for the particular model that
you wish to drive. The currently selected Model Number is displayed next to the Voltage Monitor.
WARNING: Model Programming Data changes immediately upon selection. Do not attempt to attempt to select a different
model when your model's receiver is turned ON under actual operational conditions. You may lose control of your model or the
servos may be damaged.
Selecting a Model:
1) Press the MENU UP or MENU DOWN keys to open the MODEL menu. MODEL will
flash and MODEL 1 S01 will be displayed.
2) Press the INCREASE or DECREASE keys to select the desired Model Number.
SUb-T - SERVO SUb-TRIM
The Servo Sub-Trim function allows you to fine-tune the Neutral trim setting for the steering and throttle channels, making it
possible to center the Trim Switches while ensuring the steering and throttle servo horns remain centered.
It's not unusual that when you center a servo and install the servo horn, the servo horn is not perfectly centered. The Servo Sub-Trim
function allows you to center the servo horn perfectly, without altering the servo End Point travel.
Before using the Servo Sub-Trim function you should make sure that the Steering and Throttle Trim values are set to '0'. For
more information, see the Servo Trim section on pages 15 and 16.
Installing the Servo Horn:
1) Install the servo horn (or servo saver) 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 (or servo saver) closer to being centered by rotating the servo horn (or servo
saver) 180º and reinstalling it.

GLOSSARY Of TERMS
Power Switch: Turns the transmitter ON and OFF.
Programming Keys: The programming keys are used to program the functions of your transmitter, select saved models and
change the Modulation Type.
Programming Window: Displays transmitter programming information. When the transmitter is turned ON, the BATT menu will
be selected, the current model number will be shown and the Voltage Monitor will display the transmitter's current voltage.
Servo Reversing: Used to electronically switch the direction of servo travel. For example, if you move the steering wheel to the
right and your model turns left, you can use the Servo Reversing function to make your model turn right.
Servo Sub-Trim: Used to correct the Neutral trim setting for the servos, making it possible to center the Trim Switches while
ensuring the servo horns remain centered.
Steering Trim Switch: Used to adjust the Steering Trim quickly and easily while you're driving.
Steering Wheel: Proportionally operates the model's right and left steering control. The steering wheel features a foam grip for
increased comfort, control and feel.
Suppression Capacitor: Primarily used on brushed electric motors, a suppression capacitor helps eliminate electrical noise that
could interfere with the operation of your radio control system.
Temperature Range: The range in temperature of the outside air that the transmitter can safely and reliably operate in.
Throttle Trigger: Controls the speed of the model, both forward and backward, or the model's brake.
Throttle Trim Switch: Used to adjust Throttle Trim quickly and easily while you're driving.
Voltage Monitor: Displays the current voltage of the transmitter batteries. When the transmitter batteries reach 4.6 volts, the Low
Voltage Alarm will sound.
Z-Connector: The type of servo and battery connector used by Airtronics. The Z-Connector is a universal connector which is
electronically compatible with the components of other radio control system manufacturers.
