"HAve you turned the Arducopter around a few times and waited?   The compass calibrates during the first few minutes of flight. Mine often shows a constant yawing event though the copter isn't moving. It settles down after a while…"

APM restarts on the bench

After a while, I am trying to get my APM´s running. Sometimes the APM´s restart by themselfe. I bought a really good and strong ESC, so power should not be a problem.What I can say, is that when I test the stabilization mode on the bench (rotating the APM), the aileron works correctly. If I tilt or rotate the APM too far, it restarts.All APM´s have the newest software Version.Can this be a software problem? I own 3 APM´s and 2 IMU´s. So i can exclude a hardware error...Any help or hint is very…See More
