Design and development

The Combo was designed to comply with the Fédération Aéronautique Internationale microlight category. It features a cable-braced or strut-braced hang glider-style high-wing, weight-shift controls, a two-seats-in-tandem open cockpit with a full cockpit fairing and windshield, tricycle landing gear with wheel pants and a single engine in pusher configuration.[1]

The aircraft is made from welded 4130 steel tubing, with Zicral alloy suspension. Its double surface wing is covered in Dacron sailcloth. A number of different wings and engines can be fitted to create several variants.[1]
