I can see it now- precision CNC's anodized constant speed hubs and CF blades... You wouldn't need THAT much torque to shift the blade pitch- if you have the blades mounted at their aerodynamic center thy should swing pretty easily. Full flying stabs and such are mounted that way, and they work great.

P.S. anyone with a machine shop should jump on this. The market is RIPE for the picking!
