means the parameters is too big ,it need decrease to a small amount .
The greater gain of RUD the weaker effect of the servo when in making a turn .
Gain of the throttle generally do not need to adjust, if the airspeed have a small
space velocity shock in automatic navigation ,you can decrease the parameter to suitable.
Method one: Setting FY-41AP via remote control and OSD overlay menu
In the OSD menu ,you can change the gain of the rudder control via the ―Gain‖ list of
the ―Servo Gain REV‖ option.
1) Every channel's gain can be set separately (AIL,ELE,THR,RUD), setting
range:0-99.
2) Min:0, equivalent shut down auto balance function. Max:99.
3) Gain is the sensitivity of automatic control, Will affect the navigation control and
automatic balancing effect directly. If setting too small the automatic balance effect is not
good, and if setting too much will cause the plane shaking .
4) General condition,we just suggest you use the default parameters(50).Please do
not set control gain to a very large number at your first flight .The best way is adjusting
according to more test flight. Under the condition of allowing, we suggest that the
parameter should be adjust to bigger value as far as possible, so that conducive to
balancing of the plane.
Method two: Setting FY-41AP via “FYGCS 5.11 for FY41AP and Dos”
