I have 2 x APM v1.0 and recently 1 x APM 2.0.
Both APM v1.0 have been working flawlessly.
After receiving my APM 2.0, I installed it into a X5 Wing. Just flying circuits at my local flying field in manual mode, about 3-5 mins into the flight mid way through turning downwind, the plane loses full control continues to roll inverted and goes in without power.
Motor, ESC, APM 2.0, Rx (spektrum DSMX) were all recovered, the rest went in the bin.
So I put it stuff in a second X5 wing, but this time, I put a Futaba Rx and a separate BEC, new servos.
So, maiden flight for X5 number 2 with APM 2.0, Flying perfectly in manual mode, then about 5 mins into circuits on downwind, it just keeps flying downwind, unresponsive to controls, and this time the motor went from half power to full power without my command. So now its flying straight and level, on full power and losing height without my control.
I was flying normal model aircraft circuits on both occasions, and the only common factor was the APM2.0, ESC, and motor.
If the motor was faulty, I can't see how it would go to full power and lose R/C
If the ESC was faulty, then I can't see how I would lose R/C
And if the APM was faulty, then it is possible that it wasn't allowing me to control the aircraft.

Hi Chris, not sure, I installed the firmware about 3 weeks ago via mission planner.
I wasn't flying with any assisted modes, just full manual on both occasions, and I was my model aircraft field with good view of the sky and away from any urban RF sources.
On the first airframe I was monitoring the flight via Xbee, and the last piece of telemetry was the aircraft on a 60 angle of bank and still airborne.
The second airframe I was not monitoring the flight from the ground.
I'm thinking maybe the APM shut down or reset it self?
Hai, were you using ArduPlane 2.50 or 2.60?
2.50 had a bug that could cause a crash in the case of GPS lock loss. That was fixed in 2.60.
