D-MHTN —

That's an autogyro, not a helicopter. The difference is that the rotor is not powered, it auto-rotates. Pitch and roll are controlled by tilting the rotor. A helicopter has 4 flight controls; collective, cyclic, tail rotor pedals and throttle. An autogyro has only 3; control stick, rudder pedals and throttle.

Basically a flying motorcycle

Exactly, an autogyro or "Gyrocopter", type: AutoGyro Europe MTOsport

I am not an expert in aircraft, hence my mistake. But I've corrected it ;-)

Shades of James Bond in ‘You Only live Twice’……..

These flying paperclips are great fun as long as the weather is good — as efficient as can be. If you have the bucks the AutoGyro Cavalon 915iS Gyroplane - https://youtu.be/6gp76bCMrWQ - will keep you toasty all winter.

No thanks, I prefer wings!
