Thanks

replace servo.. also check ur battery voltage (dont think this is issue)..
try a long servo arm .1st.. seen many servos do this..

but the servo arm is very weird... comes with a spring or something...
battery is a lipo 2s.

I also adjust the travel on the throttle to 90% instead of 150% maximum
