[1] 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.

This makes the design more sensitive to fly and requires special type training.
