WC Watercopter V. 2.1 2BJ: I don't think pitching moment is a problem because friction force is small. Please, criticize next version. http://en.wikipedia.org/wiki/Ground_effect_vehicle

Many thanks for your comments, Burnerjack. I think I understood pitching moment problem. This hybrid might be very unstable.

Upper screw vanes can rotate 180 deg. in order to force air to go other side. Watercopter is a name I invented for this transformer. Please vote!

TYVM, Burnerjack. I edited my post. http://en.wikipedia.org/wiki/Airboat Sorry for rough scetch.

Hello everybody! Let me share one of my ideas with you! This is a modified helicopter. It has raft instead of wheels. Its screw axis can tilt. So may be this machine can both fly and travel on the water surface. Please comment.
