I've just signed up in the forum in the hope that someone will assist me with looking at the datalog of my last fatal flight! my quad has been flying nicely for a while now. I recently upgraded to 3.1 RC5, the first few flights seems rock solid, but suddenly today the quad pitch forward 90% while it was in a stable hover and flew off in the distance and crashed. I tried pulling back pitch but there was no response. I suspect the front right esc failed, but the quad didn't roll at all, just a perfect forward pitch.
I have attached the datalog, I would really appreciate a little help with analyzing.
