Design and development

The K1 was designed to comply with the European Class 6 microlight helicopter rules. It features a single main rotor and tail rotor, a two-seats-in side-by-side configuration enclosed cockpit with a windshield, skid landing gear and a 250 hp (186 kW) Konner TK-250 turboshaft engine.[1]

The aircraft fuselage is made from carbon fibre. Its three-bladed rotor has a diameter of 6.80 m (22.3 ft). The aircraft has a typical empty weight of 290 kg (639 lb) and a gross weight of 450 kg (992 lb), giving a useful load of 160 kg (353 lb). With full fuel of 140 litres (31 imp gal; 37 US gal) the payload for the pilot, passengers and baggage is 31 kg (68 lb).[1]

The Konner TK-250 turboshaft engine includes full FADEC control that uses only three positions: stop, idle and flight. The powerplant weighs only 50 kg (110 lb) and will burn JP-1, JP-4, diesel fuel or biodiesel.[1]

The design has an electrical power system to aid autorotation in the event of main engine loss in flight.[1]
