i am pretty new to Copter flying but really like Ardupilot
It is the second time now, that my copter “crashes” without a reason with the following pattern:
While loitering without touching any stick or button: suddenly fast descending (maybe 7-10meters/s) with no control possible. Motors running.
Last time, i thought i just missed the battery warning and this was the “land” action triggered, but wondered why the land was so “hard”… didnt pay more attention to it (silly). It was about a few minutes flight time, so i guessed my time estimation was totally wrong
now: same again, landing was so hard that some parts are broken. I tried my best to analyze the log, and it seems that battery voltage was not the problem… what would you think?
