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 1000NaN0 Rotax 912 twin-cylinder or 1300NaN0 Trixy 912 Ti engine in pusher configuration. A Mitsubishi turbocharged engine of 1600NaN0 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 8.41NaN1. The aircraft has a typical empty weight of 2830NaN0 and a gross weight of 5600NaN0, giving a useful load of 2770NaN0. With full fuel of the payload for the pilot, passenger and baggage is 2280NaN0.[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]
