Hm.. I can't view .mov files so I can't see it move (tihi). But my main concern
is speed of the axle. To lift a very small model heli the blades have to spin
pretty fast, or actually very fast.
To get that speed up you'd need a pretty big airsupply like an industrial
compressor or something? Does the thin pneumatic hoses deliver enough air?
Will the motor produce enough power with the high speed?
How will you stop the thing from rotating? Will there be a tail fan or twin
rotors?
And how on earth do you convert the back-n-forth jerking motions of that model
team hub with the pistons into a rotating drive shaft!?!
Pneumatics rule!
