The aircraft is named for the native Australian Redback spider.[1]

Design and development

The aircraft was designed to comply with the Fédération Aéronautique Internationale microlight category, including the category's maximum gross weight of 450 kg (992 lb). The aircraft has a maximum gross weight of 401 kg (884 lb). It features a cable-braced hang glider-style high-wing, weight-shift controls, a two-seats-in-tandem open cockpit, tricycle landing gear and a single engine in pusher configuration.[1]

The aircraft's Wizard model wing is made from bolted-together aluminium tubing, with its single surface covered in Dacron sailcloth. Its 9.96 m (32.7 ft) span wing is supported by a single tube-type kingpost and uses an "A" frame control bar. The standard powerplant is the 37 kW (50 hp) Rotax 503 twin cylinder, air-cooled, two-stroke aircraft engine.[1]

When introduced the Redback was a single configuration model, with no cockpit fairing and no options available. In 2012 the model has evolved and offers tundra tires, intake and exhaust silencer, training bars and an aero-tow system as optional equipment.[1][2]

Reviewers Noel Bertrand et al., writing about the no-options approach in 2003 said, "The Red Back only exists in one configuration with no options — an intelligent course of action taken by this Australian manufacturer made possible by the very complete specification...All the right ingredients are there; Australian and American pilots adore them."[1]
