[1] The Astra was derived from a P&M Aviation trike design and intended to comply with the US light-sport aircraft category, although it does not appear on the Federal Aviation Administration's accepted LSA list.
[2][3] The Astra features a cable-braced hang glider-style high-wing, weight-shift controls, a two-seats-in-tandem open cockpit with a cockpit fairing, tricycle landing gear with wheel pants and a single engine in pusher configuration.
[1] The aircraft is made from bolted-together aluminum tubing, with its double surface wing covered in Dacron sailcloth.
Its 34.4 ft (10.5 m) span wing is supported by a single tube-type kingpost and uses an "A" frame weight-shift control bar.
