[1] An evolution of Corben's single-seat Baby Ace,[2] it is a parasol wing monoplane of conventional taildragger configuration.

Pilot and passenger sit side-by-side, in a cockpit that may be enclosed or left open.

A variety of powerplants may be used, and the aircraft has a power range of 85 to 120 hp (63 to 89 kW).

The company Acro Sport maintains the rights to the design, and sells plans so the aircraft can be amateur-built.
