Adjustment Dials for ELE, AIL and RUD
1.
There are 3 adjustment dials on the FY31AP. Each dial controls
servo direction during auto stabilization.
2.
Gyro Gain:
The further away from Centre (12 O’clock) the higher the Gyro gain
(sensitivity). Too low gain result is poor auto stabilization, too high gain will cause
oscillations of the aircraft. You need to adjust the gain setting based on the
requirement of your aircraft.
3.
Servo Direction:
The dials also control the direction of your servo movement.
Turning it clockwise or counter clockwise from 12 O’clock will change the direction of
your servos during stabilized flight against tilting, roll and yaw
Control Surface Movement Check
Install FY31AP as recommended in this manual, then proceed to confirm correct control
surface movement direction in Mode 2 or Mode 3.

Activate Mode 3 (Auto stabilize mode) and observe the movement direction of Aileron,
Elevator and Rudder. The direction should be as shown below. If direction is wrong, turn
the appropriate dial to the opposite side of 12 O’cl
