The plans call for a .25-.40 sized motor, and some old (circa 1992) reviews said a hot .32 was a perfect motor. While i haven't made up my mind yet, I was considering a .40 already (figuring I could go to a slower prop or practice some throttle management if necessary),

Following the same advice, I had an OS. 32 with a 10-4 prop on mine. It's definitely NOT enough engine for that plane, unless you can magically take about a pound out of the airframe.
