Bensen’s range of do-it-yourself helicopters and autogyros stem from the B-5 Gyro-Glider of 1954, which was a single-seat rotor-kite towed into the air at around 30km/h and obtained its lift by the flow of air over its autorotating rotor.
The 86 lb Bensen “Gyro-glider” which, towed behind a car, takes off at about 20 m.p.h. The B-6 Gyro-Glider could be built at home from household pipe, plywood and steel strip for about £30 in 1955.
In still air, it lands in 10-15 ft. at 7 m.p.h.
From the B-5 factory-built prototype, Bensen evolved the B-6 and B-7.
