Konner K1

The Konner K1 is an Italian helicopter designed and produced by Konner Srl of Amaro, Friuli. The aircraft is supplied complete and ready-to-fly.

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 Konner TK-250 turboshaft engine.

The aircraft fuselage is made from carbon fibre. Its three-bladed rotor has a diameter of 6.80 m. The aircraft has a typical empty weight of 290 kg and a gross weight of 450 kg, giving a useful load of 160 kg. With full fuel of 140 L the payload for the pilot, passengers and baggage is 31 kg.

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 and will burn JP-1, JP-4, diesel fuel or biodiesel.

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