Yesterday my copter crashed while doing autotune. I finished the roll axis, and just after the first twitch in pitch, it got uncontrollable and crashed. Here you can see the log:
My copter can fly either with 2 or 4 batteries, and it is funny because this is the second crash I have with 2batteries. The first one was in Loiter with 2 batteries after finishing an Autotune with 4 batteries. Same behaviour, everything was ok, I did an small input with the transmiter, and got uncontrollable again.
I am starting to suspect that the reason lies in the fact that is overpowered, and with two batteries (5 kg less) even more. As you can see, throttle output is around 23%.
After reviewing the log, is it possible that overpower is the culprit in both accicdents with two batteries?
