Bensen's current 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. From this factory-built prototype, Bensen evolved the B-6 and B-7, and from these has come the standard production model the B-8. This has a somewhat more sturdy construction and is available as a factory-built machine or in kit form for amateur construction. Two water-borne versions of the B-8 are also available: the B-8B Gyro-Boat which has a boat-type hull and twin outrigged stabilising floats, and the B-8W Hydro-Glider mounted on twin floats.
