I'm thinking maybe this has got something to do with the craft loosing GPS lock and going into P ATTI mode, all though from what i can see there were no stick rotation inputs made to make the craft start spinning after or just before it lost GPS. There are a few reports coming in from others tho about loosing GPS lock, and it has happened to me. I had 16 locked in and then bam gone. Could be one school of thought to the crash maybe.
You dont lose gps, you lose the compass. The inspire has the same kind of failsafe. If compass starts receiving bad data the craft with switch to atti mode. This would not cause the craft to spin out of control.
