CHAPTER 7: FUNCTIONS (FUNCTION MODE)

Programmable exponential adjustments are offered
on the aileron and elevator channels of your XP662
system. Exponential is a function that allows you to
tailor the response rate of the controls as compared
to the stick inputs. The purpose of exponential is to
reduce the sensitivity in the middle portion of stick
movement, while still allowing full travel at the end
of the stick movement. In other words, the end result
(travel) remains the same, although exponential
changes the rate at which it achieves this travel.
The adjustable range of the Exponential function is
from 0–100%. Zero percent (0%) is linear stick control
which means that the response rate is equal
throughout the stick control. One hundred percent
(100%) is full exponential. The larger the exponential
value, the less servo action, or sensitivity, you will
notice around the neutral setting.
Note: The Exponential function operates in
conjunction with the Dual Rate function. It is
imperative to understand the Dual Rate function
prior to adjusting the exponential values.
Exponential may be selected independently for
either the high or low rate (position 0 or 1) or both.

Accessing the Exponential Function
1. Turn on the transmitter.
2. Press the SCROLL and INCREASE buttons
simultaneously to enter the Function mode.
3. Press the SCROLL button until “EXP” appears at
the left side of the screen.
4. Press the CHANNEL button until the desired
channel appears on the screen (AI or EL).
5. Using the appropriate dual rate switch, select the
correct position to be adjusted (0 or 1).
6. Press the (+) or (-) buttons to increase/decrease
the exponential value.
7. Press the SCROLL button to access the
Sub-Trim function.
8. To exit, press the SCROLL and INCREASE
buttons simultaneously.
