Winner B150

The B150 was designed to comply with the French CNSK rules. It features a single main rotor and tail rotor, a two-seats-in side-by-side configuration enclosed cockpit with a bubble windshield, skid landing gear and a 160 hp (119 kW) Solar T62T-32 turboshaft engine.

The aircraft fuselage is made from aluminum and composites. Its two-bladed rotor has a diameter of 7.67 m (25.2 ft) and a chord of 19 cm (7.5 in). The aircraft has a typical empty weight of 400 kg (882 lb) and a gross weight of 700 kg (1,543 lb), giving a useful load of 300 kg (661 lb). With full fuel of 165 litres (36 imp gal; 44 US gal) the payload for the pilot, passenger and baggage is 157 kg (346 lb).

Reviewer Werner Pfaendler, describes the design as providing "easy and fun flying".

Production of the B150 was suspended due to deficiencies in the Solar T62 powerplant. The company said, "it was decided to abandon the Solar T62 turbine; this second-hand power source appeared to be obsolete, difficult to find in a proper condition and with limited performance". Instead the company redesigned the airframe to accept a 200 hp (149 kW) piston engine as the B200 and also a 250 hp (186 kW) TS100 turboshaft engine as the B250.
