The Servo Reversing feature of the DX3.0 is a very convenient feature when setting up a new
model. The purpose of the servo reversing function is to change the direction of the
servo rotation in relation to the wheel/trigger movement. The Servo Reversing function is
available for the steering, throttle and Auxiliary Channel 3.
Accessing the Servo Reversing Function
1. Turn the transmitter power switch on.
2. Press the
SCROLL key to access Function mode.
3. Press the SCROLL key until “REV•NORM” appears in the screen.
4. Press the CHANNEL key to select the desired channel to be changed (Steering, Throttle
or Auxiliary Channel 3).
5. Press the INCREASE or DECREASE keys to move the cursor to the desired direction
of travel.
6. To exit the Function mode, either turn the transmitter power switch off or press the
SCROLL and CHANNEL keys at the same time.

The Sub-Trim function of the DX3.0 is an electronic trimming feature that allows the neutral
position of the servo on either the steering, throttle or auxiliary channel (optional) to be moved,
while allowing the electronic trim lever for that channel to remain in the center position. This
feature is very useful as it allows the servo arm/wheel position to be moved to help with control
linkage installation, eliminating the need to make mechanical linkage adjustments.
Although the Sub-Trim function is a very useful feature, it is suggested that only small amounts
of sub-trim be used so that no unwanted, non-equal servo travel is created. It is suggested that
less than 30 points of Sub-Trim be used during adjustment. If more than 30 points of Sub-Trim
are required, it is suggested that a mechanical linkage adjustment be performed.
Accessing the Sub-Trim Function
1. Turn the transmitter power switch on.
2. Press the
SCROLL key to access Function mode.
3. Press the SCROLL key until “TRIM” appears in the screen.
4. Press the CHANNEL key to select the desired channel to be adjusted (Steering, Throttle
or Auxiliary Channel 3).
5. Press the INCREASE or DECREASE keys until the proper servo position is achieved.
6. Press the SCROLL key to access the Servo Reversing function.
7. To exit the Function mode, either turn the transmitter power switch off or press the
SCROLL and CHANNEL keys at the same time.
