I've recently rebuilt my APM 2.5 after the battery caught fire, the problem i have now when the quadcopter exceeds 10-15 feet away the controls go inverted apart from the throttle, the steps i've taken are
replying controller & APM fw and calibrating everything once these steps are taken and everything works
as it should when stood beside the copter.
Seems it only does it at a certain distance could the receiver'FrSky V8FR-II' be faulty ?
Any help would be appreciated.
