Dual Rate and Exponential (continued)
The Exponential function allows two exponential rates to be programmed and selected with a switch. Exponential
is available on the aileron, elevator and rudder channels. Changing the exponential value does not affect the
maximum control authority but only affects control sensitivity. Exponential is normally used to reduce control
sensitivity around neutral while still allowing high control authority at the extremes of throw. The sensitivity
around center can be tailored using the Exponential function to precisely adjust control feel.
Exponential rates can be controlled by their respective rate switches (aileron, elevator and rudder), or combined
on a single switch (COM AILE, COM ELEV, COM RUDD, FLAP0 or FLAP2). The choices for this are found on the
D/R SWITCH SEL screen in the System Setup Mode for Airplanes.
Exponential is available for the aileron, elevator and rudder channels. Expo values are adjustable from
-100% (full negative expo), LIN (linear), and +100% (full positive expo). The factory default settings for both the
0 and 1 switch positions are LIN or 0%. Either switch position may be selected to give any desirable EXPO rate
by placing the switch in the desired position and adjusting the value accordingly.
Note: A negative (-) Expo value will increase sensitivity around neutral, and a positive (+) Expo
value will decrease sensitivity around neutral. Normally a positive value is used to desensitize
control response around neutral.

To Adjust the Exponential
Press the DowN and SELECT keys simultaneously to access the Function Mode.
In Function Mode, use the UP or DowN key to select the DUAL RATE & EXPONENTIAL screen.
Press the INCREASE or DECREASE key to select the desired channel (AILE, ELEV or RUDD).
Move the selected channel’s dual rate switch to the desired position, 0 or 1.
Press the SELECT key until EXP is highlighted.
Adjust the Expo rate values for the selected switch position using the INCREASE or DECREASE key.
Reverse Switch
The Reverse Switch function allows electronic means of reversing the servo’s throw. Servo reversing is available
for all seven channels.
