good afternoon, the copter is not stable when flying. when moving away from the take-off point forward, there are oscillations and non-uniformity of the engines, which is also evident on the RTL. what can it be and how to fix it? flight controller Cube Orange (ardupilot 4.3.6 stable)

No idea without a flight log.

thanks, the problem was solved by updating the firmware and a new calibration. now the copter behaves stably in all modes
