APM2 strange behavior

I took my APM2/Y6 out for its maiden today. At first, it seemed ok, a little wobbly, but this is only with a few PID iterations. Something just doesn't feel right though. After some forward flight in stabilize mode, if I return the elevator to neutra

Which board did I damage?

Arducopter was flying fine for about 10 flights over the last 4 days. Today, hovering about 4 ft off the ground the heli did a flip (for no reason, it was in stable mode) and landed upside down. After repowering, 2 ESCs were sounding error codes (rap
