The aircraft is no longer listed on the Junkers Profly website and production appears to have been completed.[2]
The Junkers Trike was originally designed as a single seater or "tight" two-seater, but later stretched to provide comfortable accommodation for two occupants.
The aircraft was designed to comply with the Fédération Aéronautique Internationale microlight category, including the category's maximum gross weight of 4500NaN0. The aircraft has a maximum gross weight of 4500NaN0. It features a cable-braced hang glider-style high-wing, weight-shift controls, a single-seat or two-seats-in-tandem open cockpit with an aerodynamically streamlined cockpit fairing, tricycle landing gear with wheel pants and a single engine in pusher configuration.
The aircraft fuselage is made from fibre glass, with its single or double surface wing covered in Dacron sailcloth. The typical wing used is of 9.61NaN1 span, is supported by a single tube-type kingpost and uses an "A" frame weight-shift control bar. The standard powerplant factory supplied was the twin cylinder, liquid-cooled, two-stroke, dual-ignition 640NaN0 Rotax 582 engine.
With the Rotax 582 the aircraft has an empty weight of 1860NaN0 and a gross weight of 4500NaN0, giving a useful load of 2640NaN0. With full fuel of the payload is 2330NaN0.
A number of different wings can be fitted to the basic carriage, including those made by Bautek and La Mouette. The aircraft was certified in Germany to DULV standards.
