Design and development edit

The aircraft was derived from the Airsport Sonata motor glider and designed to comply with the Fédération Aéronautique Internationale microlight rules. It features a cantilever low-wing, a T-tail, a two-seats-in-side-by-side configuration enclosed cockpit, fixed tricycle landing gear and a single engine in tractor configuration.[1][2]

The Sonet is made from composites. Its polyhedral wing comes in three optional spans: 10.2 m (33.5 ft), 11.4 m (37.4 ft) and 15 m (49.2 ft). It requires an engine of about 65 hp (48 kW) and no more than 60 kg (132 lb). Standard engines available are the 64 hp (48 kW) Rotax 582 two-stroke and the 60 hp (45 kW) HKS 700E four-stroke powerplant.[1][2][3]
