Accessing the
Direct Trim
Mode
The Direct Trim Mode function of the DX3.0 is accessible through the use of the electronic
throttle or steering trim levers, as well as the two electronic grip levers (A&B) located on
the upper portion of the grip handle. This function allows for quick trim adjustment of these
controls.
To access the Direct Trim Mode function, turn the transmitter power switch on. Next, move
the desired trim lever to be adjusted. The appropriate screen for the selected trim lever will
be displayed. To adjust, simply move the trim lever in the desired direction until the correct
amount of trim is achieved. Once the desired trim is achieved, the screen will return to the
Normal display screen after approximately two seconds from the last trim input. If the
Increase or Decrease keys are pressed any time during the two seconds, the system will
return to the previous screen in use.
*Note: When Auxiliary Channel 3 function 2P is selected, the two screens above are not
present.

Servo
Reversing
REV • NORM
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 key 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 key 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.
