Design and development
Anton Flettner was an early rotary-wing pioneer in Germany, he developed a torqueless rotor by powering it with small engines fixed directly to the blades driving propellers. this arrangement drove the rotor without transmitting torque (other than bearing friction) to the fuselage. A successful tethered flight was carried out in 1932, but the aircraft was destroyed soon afterwards when it overturned in a gale.Specifications (variant specified)
