The aircraft was designed to comply with the Fédération Aéronautique Internationale microlight rules. It features a strut-braced high-wing a two-seats-in-side-by-side configuration enclosed cockpit, fixed tricycle landing gear and a single engine in tractor configuration.[1][2][3]

The aircraft is made predominantly from welded steel tubing, with its flying surfaces covered in doped aircraft fabric. Its 9.40 m (30.8 ft) span wing, has an area of 15.04 m2 (161.9 sq ft) and it constructed using a welded steel tube lattice spar, aluminium tube ribs and a laminate leading edge. The standard engine is the 80 hp (60 kW) Rotax 912UL four-stroke powerplant. The cockpit is 1.15 m (45.3 in) wide and is intended to accommodate "bulky crew".[1][2][3]
