Well was flying great thanks to all my practice on the the sim. flew for 5 mins and the it abruptly died abt 60 ft high.. i autoed it all the way dow and only damage was the landing skids.. upon investigation the coil of the brand new glow plug was completely burnt out and that was the problem. put a new one in a fired right up.. the engine is a OS50sx-h.....

I was just curious to what may cause these problems.... i.e. to lean or somethin else...just really dont want it to happen again...

Any help is greatly appreciated!!!!</p>
