Not sure if this is firmware related or due to a setup or other issue yet, but I had a close call today with my newly built DJI F450 w/PX4 running 3.0.0-rc1 ArduCopter software.
I was hovering my quad 20 feet up in loiter mode. It had been flying for a minute or so, fighting wind gusts but generally holding position.
All of a sudden, it tipped forward to appx 45 degrees, throttle went to full, and flew in a straight line away from me at very very high speed. Came within inches of a nearby building before I lost sight of it over the roofline.
I flicked over to stabilize mode, gave it full throttle and prayed, and luckily it climbed out and I was able to fly it home.
Not sure what happened, I am fairly certain I did not lose radio contact.
I have log files labelled 1.bin, 2.bin, etc... on my sd card can I use these to figure out what happened?

I guess you were pretty bleeding edge by combining two new technologies that are not yet stable : PX4/APM SW port + new version 3-rc1 of APM's firmware. Wow that's risky !
