Arducopter - near flyaway

It almost got out of sight, caused by sudden yaws around z-axis. Still investigating the problem... Funny thing i noticed, was that backward flying does not cause these , only fwd. And in this case all that was needed was push by wind and it rotated and shoot to right.

what a ride. I think your compass is at fault here. but it would take some looking at the logs to be sure.
