Ari,

Good question. I hadn't questioned why it worked.

I made a temporary axle and wheels and taped it to the HydroSkimmer to eliminate the possibility of the effect you noted.

On wheels, it turned a bit better and at much lower throttle.

I think this arrangement; shallow inverted V tail, may provide good yaw control on the ground for an autogyro and also provide good roll control in the air.
