Hello, I need some help diagnosing the cause of a crash while attempting my first autotune. My copter was flying well before this. It was able to hover stably in atlhold and Poshold flight modes. I even completed several waypoint missions, in varying conditions successfully.
A couple of minutes into the autotune flight my copter spontaneously dropped from the sky. This caught me off guard. Until then it was performing normally. No excessive oscillations. Some drifting after each roll event, which I thought was normal and consistent with videos I have seen. I looked at the logs and replayed the flight. The crash occurred right after a %50 inc. in D. I am not sure if this is significant.
I followed the Wiki doc and video explaining autotune. Maybe, I missed a crucial setup step?
