End-Point Adjustment (Function Mode)
The End-Point Adjustment feature of the XR2i allows the maximum travel of both the
steering and throttle servos to be increased or decreased in each direction to achieve the
exact servo movement needed. The End-Point Adjustment range is from 0% to 125% and
is factory set to 100% for both channels. The value displayed on the screen depends on
the current position of the steering wheel, trigger, or trim lever to be adjusted. This
feature is very useful either to maximize servo travel or to reduce servo over-travel to
eliminate servo binding (servo moves further than control mechanism allows), without
the need for mechanical linkage adjustment.
The screens below are accessed by turning the wheel to the desired direction to be
adjusted (left or right), by moving the trigger to the forward or backward (brake) position,
or by moving the Grip Lever A to the forward or back positions.
Accessing The End-Point
Adjustment Function
1. Turn on the transmitter power switch.
2. Press the Scroll key to enter Function mode.
3. Press the Scroll key until "EPA" appears in small letters on the left side of the screen.
4. Press the Channel key to select the desired channel to be adjusted.
Steering = ST R/B(steering right) or ST L/F (steering left)
Throttle = TH L/F (forward) or TH R/B (braking or reverse)
5. Move the steering wheel or trigger in the desired direction for adjustment (left/right,
forward/reverse or brake). Press the Increase or Decrease key to achieve the desired
amount of travel. Move the wheel or trigger in the opposite direction to adjust the travel
in the opposite direction.
6. Press the Scroll key to access the Sub-Trim function.
7. To exit the Function mode, either turn off the transmitter power switch or press the
Scroll and Channel keys at the same time.
Note: When setting the end point adjustment values for the steering function, it is
suggested that, if possible, the maximum travel values be set to an equal value in both
directions to maintain proper steering control.

Sub-Trim (Function Mode)
The Sub-Trim function of the XR2i is an electronic trimming feature that allows the
neutral position of the servo on either the steering or throttle channel 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
