Pro Boat JR XR3i - Manual (Page 23)

The Exponential feature of the XR3i 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 XR3i provides both posi-
tive (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 the Function mode.
3. Press the Scroll key until "EXP" appears in small letters
on the left side of the screen.
4. Press the Increase or Decrease keys to select the desired
exponential value.
5. Press the Scroll key to access the travel End-Point
Adjustment function
6. To exit the Function mode, either turn off the transmitter
power switch or press the Scroll and Channel keys at the
same time.
