No main helicopter rotors - it just used rotating wings with the jets on the tips.

I have demonstrated the concept of the tip-jet helicopter from the 1950s through this build. It is a controllable helicopter- good handling even with the experimental main rotors. Watch this video:

Tip-Jet Helicopter

Custom Rotor

HOW TO FLY

1) Throttle to 100%
2) Then VTOL up to move up, and VTOL 50% or halfway to bring down the chopper. The throttle is not supposed to control the up and down movement of the flight.
- forward/slow down: Pitch
- Roll: Roll
- Yaw: Yaw

Inspired by tip-jet helicopter from the 1950s: XHOE-1

The Hiller YH-32 Hornet (company designation HJ-1) is an American ultralight helicopter built by Hiller Aircraft in the early 1950s. It was a small and unique design because it was powered by two Hiller 8RJ2B ramjet engines mounted on the rotor blade tips which weigh 13 lb (5.9 kg) each and deliver an equivalent of 45 hp (34 kW) for a total of 90 hp (67 kW).[3] Versions of the HJ-1 Hornet were built for the United States Army and the United States Navy in the early 1950s.

Theoretically, With this type of propulsion, there is almost no torque created by the main rotor. And so, to my friends who want to try without the tail-rotor, Download from the link below -
