Consideration for a helicopter that is as easy to fly as a plane;
Characteristic:
~ How:
The ability to takeoff, perform flight maneuvers and land, without having to use the pedals.
~ Intermeshing configuration.
Immediate response to cyclic control inputs.
~ Extremely rigid rotors.
Minimal cross-coupling from cyclic control inputs.
~ No coning angle in rotor.
Minimal vibration.
~ No coning angle in rotors, plus additional blades.
On loss of power; automatic entry into glide slope (autorotation).
~ Rotor (not engine) governor.
Just provoking thought.
