I still can’t figure out what caused it, but after filming the old mill the Hubsan took off and had a mind of it’s own.
Tried to disarm the motors, it only resulted in a fast descent, it crashed in a tree and fell on the ground, motors were still running. could disarm it only when I was closeby
The Hubsan was completely uncontrollable
Unfortunately there are no firmware updates for this drone, so cannot try to fix it with that.
That’s it, I am not flying this drone anymore.
