EXP — Exponential Settings
Exponential settings may be used to changes the response curve of the servos to make
flying more pleasant. You can make the servo movement less or more sensitive around neutral
for aileron, elevator, throttle (except HELI type), and rudder. It can also be set for each side of
the dual rate switches. Negative exponential (-) makes the servo movement around the stick
neutral less sensitive and positive (+) makes the servo movement more sensitive.
For throttle, exponential is applied from the end of travel rather than for neutral like the
other controls. When the (-) side is increased, the idle sensitivity decreases and the high throttle
sensitivity increases. This is best understood by experimenting with a servo.
Inputting Exponential Values
1. Get to the EXP screen with the up or down arrow keys.
2. Use the CURSOR key to select the channel (aileron, elevator, throttle or
rudder) you wish to change the response curve. The active channel
number is indicated by the arrow above or below. The arrow’s position
depends on the position of that channel’s dual rate switch. In the figure, the aileron (CH1)
exponential setting at the D/R switch’s lower position is being programmed.
3. Choose the amount of exponential with the (+) or (–) keys. You may set the amount for both
sides of the switch simply by flipping the switch to the other position (the arrow will also
switch sides). If you wish to return to the original 0% value, press both keys simultaneously.
4. Repeat this procedure for the exponential settings on the other channel remaining.
