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.Bayerl, Robby; Martin Berkemeier; et al: World Directory of Leisure Aviation 2011-12, page 193.

Design and development

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 {{convert|75|hp|kW|0|abbr=on}} four stroke engine.

The aircraft fuselage is made from bolted-together aluminum tubing, with the tailboom built from carbon fibre. Its {{convert|6.10|m|ft|1|abbr=on}} diameter two-bladed rotor has a chord of {{convert|20|cm|in|1|abbr=on}}, 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 {{convert|193|kg|lb|0|abbr=on}} and a gross weight of {{convert|386|kg|lb|0|abbr=on}}, giving a useful load of {{convert|193|kg|lb|0|abbr=on}}. With full fuel of {{convert|58.8|L}} the payload is {{convert|151|kg|lb|0|abbr=on}}.

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.
