Just imagine the result of your idea - an ideal rotor without any friction at the root in order to avoid rotation of the body. Now how would you steer that thing ? If it already moved you could hope to use aerodynamic forces via some kind of rudder, but all that would be completely unstable, not to mention that there simply always is friction and even motion of the fluid from stationary tanks in the main body out to the wingtips would induce a moment and you would need rotor tilting mechanisms ... so in order to be able to point the nose in a stable direction you'd want to be able to use a tail rotor or equivalent - at least in such a basic design. I suppose that a Kamov-like co-axial twin-rotor with wingtip fans could be stabilized with modern fly-by-wire electronics, but in the 1950s ... no way.

I can't understand why it would need a tail rotor if the jet engines were on the tip of the rotors. That should make it unnecessary since there would be no torque affecting the helicopter.

I am currently building a similar type of Helicopter.A 5h.p. Generator powers the motors that turn props at wingtips.Similar to the jet tip.Contacts similar to a car horn allow the wing rotate and tilt.I have pictures of the nearly complete prototype but don"t know how to send them to you. Charlie

I have got an enquiry concerning some photos of the Mil V-7 from the Monino-Museum for a scale model project. Please help me.
