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.
23. 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.
1.
In Manual mode (stabilization deactivated) confirm that the control surfaces do to react when
your aircraft is tilted or rolled.
2.
Activate Mode 2 (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’clock to get the action direction correct:
AILERONS -Roll the plane to see the following action:
l
Incline the plane to the right (roll right). The ailerons should give a control signal to counter
this roll direction (see below). Same as when rolled to the left. If the ailerons move correctly, the
knob has been turned in the right direction. You can now adjust gain by moving nearer (low
gain) or further away (high gain) from center;
l
If the ailerons do not follow the movements shown above, simply turn the aileron knob to the
opposite side (beyond centre). You should now see the correct aileron movement.
