Design and development

The Free Bird was designed to comply with the US light-sport aircraft rules. It features a cantilever low-wing, an enclosed cabin with two-seats-in-side-by-side configuration accessed by doors, fixed tricycle landing gear, with wheel pants and a single engine in tractor configuration.[1]

The aircraft structure is made entirely from composite material, with the fuselage a monocoque design. Its 9.45 m (31.0 ft) wing has an area of 11.06 m2 (119.0 sq ft), is built with dual spars and features winglets. It has a low-mounted horizontal stabilizer with a single spar. Both the seats and the rudder pedals are adjustable for pilot height. The cabin is 107 cm (42 in) in width. The standard engine used is the Austrian 100 hp (75 kW) Rotax 912ULS, four-stroke powerplant, driving a Czech-built Woodcomp three-bladed, ground adjustable propeller.[1]

As of February 2017, the design does not appear on the Federal Aviation Administration's list of approved special light-sport aircraft.[2]
