Design and development

The aircraft was designed to comply with the Fédération Aéronautique Internationale microlight rules. It features a cantilever low-wing a two-seats-in-side-by-side configuration enclosed cockpit, fixed or retractable tricycle landing gear and a single engine in tractor configuration.^[1]

The aircraft is made from composites. Its 8.44 m (27.7 ft) span wing has a small wing area of 9.77 m² (105.2 sq ft). The standard engine is the 100 hp (75 kW) Rotax 912ULS four-stroke powerplant.^[1]

A fixed gear version with a larger wing span and area as well as a higher gross weight was developed for the US light-sport aircraft category and is marketed as the Gobosh 800XP.^[1]
