Design and development

The Princess was derived from the Trixy G 4-2 R. It features a single main rotor, a two-seats-in tandem enclosed cockpit, tricycle landing gear with wheel pants, plus a tail caster and a four-cylinder, liquid and air-cooled, four stroke 100 hp (75 kW) Rotax 912 twin-cylinder or 130 hp (97 kW) Trixy 912 Ti engine in pusher configuration. A Mitsubishi turbocharged engine of 160 hp (119 kW) is also available. The Mitsubishi powerplant includes a main rotor prerotator capable of producing 280 rpm for takeoff, reducing the takeoff roll.^[1]

The aircraft fuselage is made from composites. Its two-bladed rotor has a diameter of 8.4 m (27.6 ft). The aircraft has a typical empty weight of 283 kg (624 lb) and a gross weight of 560 kg (1,235 lb), giving a useful load of 277 kg (611 lb). With full fuel of 68 litres (15 imp gal; 18 US gal) the payload for the pilot, passenger and baggage is 228 kg (503 lb).^[1]

Unlike many other autogyro builders Trixy Aviation uses a swash plate in its rotor head designs, rather than a tilt head. This makes the design more sensitive to fly and requires special type training.^[1]
