Newberry,

I have also noticed that the prop does not fold when gliding. Maybe if the prop folded easier it would solve the problem (a little oil in the folding area?)

I'm not sure the holes for cooling would be a good idea. Seems like it would weaken the nose. I have had a few nose-hit landings and the nose has barely survived. The heatsink sounds like a great idea though.

I'm glad you guys mentioned other motors.... perhaps I could buy a better motor. I'm concerned that the prop will not fit on another properly though. I'm not sure how standard that shaft is. The motor would be kind of useless if it ended up being too big or small. What do you think? Stock motors are $12.
