◇To Adjust the Exponential
Press the DOWN and SELECT keys simultaneously to access the Function Mode.
In Function Mode, use the UP or DOWN keys to select the DUAL RATE and
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
on the screen.Using the INCREASE or DECREASE key to adjust the Expo rate values.
◆Reverse Switch
The Reverse Switch function allows electronic means of reversing the servo’s throw
. Servo reversing is available for all seven channels.
◇To Access the Reverse Switch Mode
Press the DOWN and SELECT keys simultaneously to access the Function Mode.
In Function Mode, use the UP or DOWN key to select the REVERSING SW screen.
Press the SELECT key to access the desired channel.
Press the INCREASE or DECREASE keys to reverse the servo direction
The available channels are:

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.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), straight line, and +100% (full positive
expo). The factory default settings for both the 0 and 1 switch positions are straight
line or 0%. You can select one between the witch's two position to open the desirable
EXPO rate. The position of the switch is the place of ajusting the accordingly EXPO
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 insensitize control response around neutra
value.
◆Sub-Trim
The Sub-Trim function allows you to electronically adjust the centering of each
servo. Sub trim is individually adjustable for all seven channels, with a range of +
or - 125% (+ or - 30 degrees servo travel).
Caution: Do not use excessive sub-trim values as it is possible to overdrive the
servo’s maximum travel.The available channels are:
● THRO: Throttle ● AILE: Aileron ● ELEV: Elevator ● RUDD: Rudder
● GEAR: Retractable Landing Gear ● FLAP: Flap ● AUX2: Auxiliary 2
