for it to work as the storie goes, you would have to cling onto something every time you landed to get the RRPM high enough otherwise it would just take enough weight to drag you along. or you could have a pitch control and use the rotor inertia. prety much the same as a glider, if you point it into a 50knot wind it could lift off and fly backwards till the airspeed fell away, you would need to land before it got below the stall speed of coures.
