RE: engine stall OSHyper50
I have seen that happen, only once though. the cause was the pilot was trying to max out the engine power. which meant he was running very lean, and for a very long time.
I have pics of it somewhere. The entire upper portion of the engine came off completely...the pilot was able to land ok, it was still running (dont know how) when he landed. it was just running like crap. the motor just fell apart when he pulled it out.
