I began flying like normal but from the begining something felt a little strange. When in Poshold it would initially drift to the right when trying to move forward then it would correct itself. It was a little windy so i figured that was the problem. I was using my phone for telemetry and around 10 mins I started to get frequent disconnection from the telemetry. I started feeling uncomfortable flying anymore so I directed it back towards me and hit RTL (where the video starts). RTL seemed great so I didn't pay much mind to it. After descending to a few feet above landing area it started to quickly drift to right. I gave input but b/w orientation and panic I couldn't save it. Auto Analysis of the log says compass failed/high mag field and vcc problem. I cant figure out when mag field was high or did my compass fail? did vcc create a problem? I burnt an ESC and motor i assume b/c in the trees it kept spinning and got too hot. My GPS mount bent and I noticed there is bare wire showing on the plug of the mag. but not sure if that happen after crash. I plugged in pixhawk to see if compass is bad still but everything seems fine. Not sure if I had a hardware failure or maybe short in the wire? I cant recreate the problem. Maybe something really created high magnetic field but i fly here all the time and never had a problem with mag field.
If someone could check out my log with video and help figure what happen i would greatly appreciate it. I was very lucky but I'm afraid to fly again until i know for sure what happen.
