I suspect equipment failure as my desired pitch and roll were vastly different than the observed and my vibrations went off of the chart at the same time. Does the mag interference typically correlate with this as well?
I'm running copter version 3.4.3 550m hex 4s
How is your compass mounted? I assume that you are using an external compass/GPS module? I have found that mounting location is very critical for good performance
You may want to check your compass, your mag field has a very large interference as well. I agree there looks to be a mechanical failure as the desired roll/pitch radically diverges towards the end of the flight
Looks Like Prop Broke
i'm sorry I was running 3.3.3 during the crash
