Design and development

The aircraft was designed by von Schoenebeck as his first full-sized aircraft after a career of designing competition model gliders. The Bateleur was intended to comply with the Fédération Aéronautique Internationale microlight rules and US light-sport aircraft rules. The company also plans to type certify it to FAR 23 standards.[1][3]

The Bateleur features a delta wing layout with a canard. The wing is a cantilever low-wing design. The aircraft also features two-seats-in-tandem under separate bubble canopies, fixed or optionally retractable tricycle landing gear and a single engine in pusher configuration. The light-sport version will have fixed landing gear as that category's rules require and a gross weight of 600 kg (1,323 lb).[1][4]

The aircraft is made from composites. Its 6.25 m (20.5 ft) span wing has an area of 14 m2 (150 sq ft) and flaps mounted on the main and canard wings. Standard engines available are the 100 hp (75 kW) Rotax 912ULS and the turbocharged, 115 hp (86 kW) Rotax 914 four-stroke powerplants. Landing gear is fixed for the US light-sport aircraft market or retractable for the homebuilt version.[1][2]

Production was initially established in South Africa, moved to Germany, and finally to the United States in 2012.[1][2]

As of March 2017, the design does not appear on the Federal Aviation Administration's list of approved special light-sport aircraft.[5]
