The Junkers Profly Junkers Trike is a German ultralight trike, designed by Junkers Profly of Kulmbach and manufactured under contract in the Czech Republic. When it was available the aircraft was supplied complete and ready-to-fly.^[1]

The aircraft is no longer listed on the Junkers Profly website and production appears to have been completed.^[2]

Design and development

The Junkers Trike was originally designed as a single seater or "tight" two-seater, but later stretched to provide comfortable accommodation for two occupants.^[1]

The aircraft was designed to comply with the Fédération Aéronautique Internationale microlight category, including the category's maximum gross weight of {{convert|450|kg|lb|0|abbr=on}}. The aircraft has a maximum gross weight of {{convert|450|kg|lb|0|abbr=on}}. 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.^[1]

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 {{convert|9.6|m|ft|1|abbr=on}} 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 {{convert|64|hp|kW|0|abbr=on}} Rotax 582 engine.^[1]

With the Rotax 582 the aircraft has an empty weight of {{convert|186|kg|lb|0|abbr=on}} and a gross weight of {{convert|450|kg|lb|0|abbr=on}}, giving a useful load of {{convert|264|kg|lb|0|abbr=on}}. With full fuel of {{convert|43|l}} the payload is {{convert|233|kg|lb|0|abbr=on}}.^[1]

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.^[1]
