The Gyro-Kopp-Ters Midnight Hawk is an American autogyro, designed by Bob and Arden Kopp and produced by their company, Gyro-Kopp-Ters of Lake City, Florida. The aircraft is supplied as a kit for amateur construction or as a complete ready-to-fly-aircraft.[1]
Design and development
The Midnight Hawk features a single main rotor, a single-seat open cockpit with a windshield, tricycle landing gear with wheel pants and a four-cylinder, air-cooled, four-stroke, 90 hp (67 kW) Subaru EA-82 automotive conversion engine in pusher configuration. The engine is available with a belt reduction drive or as a direct drive version.[1]
The aircraft mounts a 25 ft (7.6 m) diameter Dragon Wings main rotor made by Rotor Flight Dynamics, with a chord of 7 in (17.8 cm). Standard equipment fitted includes a hydraulic pre-rotator. The propeller used is a three-bladed Powerfin composite, ground adjustable with a 5 ft (1.5 m) diameter. The aircraft has an empty weight of 510 lb (231 kg) and a gross weight of 810 lb (367 kg), giving a useful load of 300 lb (136 kg).[1][2]
The company estimates the assembly time from the supplied kit as 60 hours.[2]
