Quander Airpfeil

The Quander Airpfeil (Air-Arrow) is a German ultralight trike that was designed and produced by UL Flugzeugbau Quander of Petershagen. The aircraft is supplied complete and ready to fly.

Design and development
The Airpfeil was designed to comply with the Fédération Aéronautique Internationale microlight category, including the category's maximum gross weight of 450 kg. The aircraft has a maximum gross weight of 400 kg. It features a cable-braced hang glider-style high wing, weight-shift controls, a two-seats-in-tandem open cockpit without a cockpit fairing, tricycle landing gear and a single engine in pusher configuration.

The aircraft is made from bolted-together aluminum tubing, with its double surface Vento 13 m2 wing covered in Dacron sailcloth. The 9.5 m span wing is supported by a single tube-type kingpost and uses an "A" frame weight-shift control bar. The wing is supported by a three-tube tetrahedral structure, which is no longer common on modern trikes, but provides good strength at light weight. The powerplant is a twin-cylinder, liquid-cooled, two-stroke, dual-ignition 50 hp Rotax 582 engine.

The aircraft has an empty weight of 130 kg and a gross weight of 400 kg, giving a useful load of 270 kg. With full fuel of 62 L the payload is 225 kg.
