The Redback Buzzard is an Australian helicopter that was designed and produced by Redback Aviation of Hoppers Crossing, Victoria. The aircraft was intended to be supplied as a kit for amateur construction, but only one prototype was ever completed and development ended.[1][2]

Design and development[edit]

The Buzzard was based on the second generation Star Aviation LoneStar helicopter to which Redback own the rights. The Buzzard was designed to be a minimalist helicopter, using a maximum of off-the-shelf parts and to comply with the homebuilt aircraft rules. It features a single main rotor, a single-seat open cockpit without a windshield, skid-type landing gear and a Suzuki 75 hp (56 kW) four stroke engine.[1][2]

The aircraft fuselage is made from bolted-together aluminum tubing, with the tailboom built from carbon fibre. Its 6.10 m (20.0 ft) diameter two-bladed rotor has a chord of 20 cm (7.9 in), with anti-torque handled by a conventional two-bladed tail rotor. The main rotor transmission uses a combination of V-belts and toothed belts. Pitch link controls are mounted inside the hollow rotor mast tube. The aircraft has an empty weight of 193 kg (425 lb) and a gross weight of 386 kg (851 lb), giving a useful load of 193 kg (425 lb). With full fuel of 58.8 litres (12.9 imp gal; 15.5 US gal) the payload is 151 kg (333 lb).[1]

The company indicates that only one prototype was built and that it was sold, ending development of the aircraft, in favour of a new design, the Redback Aviation Spider.[2]
