Interesting.. from what I gather, the most important or critical parts are the blades and rotorhead. I get the impression that if you spend the time to build, or the money to buy a set of nice blades and attach them to a well designed rotorhead you have done a lot towards a nice handling model.

I liked the idea I read elsewhere on this forum about finding the perfect airfoil and then grinding a router blade to that shape so you can quickly shape all you want.

Anyway, thanks again for the info guys.
