The Freebird II is a family of American side-by-side two-seat, high wing, tricycle gear, pusher configuration single engined kit aircraft originally designed for construction by amateur builders by the Freebird Airplane Company of Marshville, North Carolina and later Pro Sport Aviation of Wingate, North Carolina.[1][2][3][4]

The Freebird II was produced until late 2014 by Free Bird Innovations of Detroit Lakes, Minnesota as the LiteSport Classic.[5][6]

Development

The Freebird I was introduced at Sun 'n Fun 1996 and was intended to meet the requirements of the US FAR 103 Ultralight Vehicles category under the two-seat trainer exemption, although it is now offered in the US Light Sport Aircraft or amateur-built categories.[1][3][4]

The Freebird II is constructed from bolted aluminum tubing, covered with doped aircraft fabric. The aircraft features conventional three-axis controls, including a trim system. The tricycle landing gear is steered by differential braking and a castering nosewheel. The company estimated that an average builder would take 120 hours to build the aircraft from the assembly kit.[1][6]

The standard engine recommended is the two-stroke {{convert|50|hp|kW|0|abbr=on}} Rotax 503 and with this engine the standard empty weight is {{convert|385|lb|kg|0|abbr=on}}. The {{convert|64|hp|kW|0|abbr=on}} Rotax 582 is also used.[1][6]

The Freebird II's wings can be folded in five minutes by one person and the aircraft can then be trailered or stored. Options available included full cabin doors, flaperons, brakes, wheel pants and a custom-fitted trailer.[1]
