I looked at the logs. There really isn't much info in it, no motor data. I really can't see anything helpful.
The only facts I can see:
1) Yaw was not commanded externally. So this wasn't a user error or Tx/Rx problem.
2) Yaw was not commanded internally. The video shows the copter rotating clockwise. The data shows the copter is rotating clockwise. The target yaw is 10 ° CCW of the actual yaw, which means the yaw controller was not causing the yaw. It would have been trying to stop it, but couldn't.
Were any of the motors rotated after landing/crashing?
Manuel, I would guess that you had a mechanical failure. Does the Octo use round tube arms? Could a motor have rotated on the arm so it was pointing sideways? That's the only way I could see an Octo rotating that fast.

It happened to me once.
