Method one: Setting FY-41AP Lite 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.
3) Gain means the sensitivity of automatic control, will affect the navigation control
and the effect of the automatic balancing directly. If setting too small the effect of the
automatic balance is not good, and if setting too much will cause the plane shaking.
4) General condition, we suggest that 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.
