Air scooter is a complex machine, rotor head have a flapping hinge and blades have a pre-cone angle...
Also GEN H-4 have pre cone angle but not flapping hinge, and in this case I don't understand why (Perhaps Dave can clarify ideas).
Shoeffman type use two simple propeller, this permit a perfect hovering and little longitudinal movements, Air scooter have an high velocity compared with an hovercopter.
Jens I think that blades of your project need of a flapping hinge and pre-cone angle because have a big diameter and are more similar to a rotor of a propeller.
