interesting link, thanks.

edit: in a vertical auto-rotation at zero pitch, on a real heli, are the blades going to stay spinning at full speed while also generating lift to counter acceleration downwards? doesn't the relative wind work to slow them to a stop pretty quick?

nevermind I see the diagram now.. even at zero or small positive pitch, part of the rotor drives the rotation, the other part just creates lift.. and the two are in equilibrium.. (as long as it is falling, or in the case of the gyro copter, being pushed along).
