The "TT" designation indicates "Tall Tail". The aircraft has higher landing gear, allowing the engine to be placed on the vertical center of gravity, which eliminates pitch changes with throttle application. [1]

Design and development

The Double Eagle TT was designed to comply with amateur-built aircraft rules. It features a single main rotor, a two-seats-in tandem open cockpit without a windshield, tricycle landing gear with wheel pants and a four-cylinder, liquid-cooled, four-stroke, single-ignition 150 hp (112 kW) Subaru EA82 automotive engine in pusher configuration. [1]

The aircraft fuselage is made from welded 4130 steel tubing, with some aluminum parts. Its two-bladed rotor has a diameter of 30.00 ft (9.1 m). The aircraft has a typical empty weight of 575 lb (261 kg) and a gross weight of 1,150 lb (520 kg), giving a useful load of 575 lb (261 kg). With full fuel of 12 U.S. gallons (45 L; 10.0 imp gal) the payload for the pilot, passengers and baggage is 503 lb (228 kg). [1]

The standard day, sea level, no wind, take off with a 150 hp (112 kW) engine is 200 ft (61 m) and the landing roll is 10 ft (3 m). [1]

The manufacturer estimates the construction time from the supplied kit as 100 hours. [1]
