Endpoint
Adjustment
The Endpoint Adjustment feature of the DX3.0 allows the maximum travel for the steering,
throttle and Auxiliary Channel 3 (optional) servos to be increased or decreased in each
direction to achieve the exact servo movement needed. The Endpoint Adjustment range is
from 0% to 125% and is factory-set to 100% for all three 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 (servos move further than the 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
toggling the Grip Button C.
Channel 3 Screens (optional)
Accessing the Endpoint Adjustment Function
1. Turn the transmitter power switch on.
2. Press the SCROLL key to access Function mode.
3. Press the SCROLL key until EPA appears on the left side of the screen.
4. Press the CHANNEL key to select the desired channel to be adjusted.
5. Move the steering wheel, trigger or Grip Button C 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, trigger or Grip Button C in the
opposite direction to adjust travel in the opposite direction.
Note: For Auxiliary Channel 3 function, if LN is selected, only L/F is adjustable. And if
Emergency Steering Button is Eb or LA, Auxiliary Channel 3 defaults to Grip Lever A.
6. Press the SCROLL key to access the Mixing Adjustment 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.
Note: When setting the Endpoint 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.

Function Mode
Exponential
The Exponential feature of the DX3.0 allows you to alter the response rate of the steering or
throttle control around neutral without affecting the maximum amount of steering or throttle
available. The adjustment range is from -100% to 0% (Linear) to +100%. Exponential is
factory-set to linear for both steering and throttle. Exponential is often used to settle down a
car that is twitchy around center without giving up maximum steering response. The DX3.0
provides both positive (increase sensitivity at neutral) and negative (decrease sensitivity at
neutral) exponential values.
Accessing the Exponential Function
1. Turn the transmitter power switch on.
2. Press the SCROLL key to access Function mode.
3. Press the SCROLL key until EXP appears on the screen.
4. Press the INCREASE or DECREASE key to select the desired exponential value.
5. Press the SCROLL key to access the travel Endpoint Adjustment function.
6. To exit the Function mode, either turn the transmitter power switch off or press the
SCROLL and CHANNEL keys at the same time.
