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:

 THRO:  Throttle      

 AILE:  Aileron      

 ELEV:  Elevator     

 RUDD:  Rudder

 GEAR:  Retractable Landing Gear       

 FLAP:  Flap      

 AUX2:  Auxiliary 2

To Access the Sub-Trim Function

Press the DOWN and SELECT keys simultaneously to access the Function Mode.

In Function Mode, use the UP or DowN key to select the SUB TRIM screen.

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
