Recently a friend of mine had a ZDZ 80 overheat and lock up after only about 15 flights. He had followed the break-in procedures as provided by the mfg. Up until that point he really liked the engine. I have been thinking about getting one of the same engines myself but now I'm a little hesitant.

I wanted to know what other people thought about the engine and if anyone else had had a problem like this with the same engine.
