Thanks for the input. The blades seem to spin-up pretty well, I'll have to work on the pitch, however; it's not like my helicopters which have adjustable linkage to control pitch: It's a piece of steel that must be bent to control pitch. My biggest fear is breaking the blades; I didn't think they could be replaced. What's everyone else using for blades? Are helicopter blades adaptable?

Yes it is a belt drive, is that good or bad?

Thanks again.
