The Spirit was the Standard Class design that paralleled the company's FAI 15-Metre Class Falcon.

The aircraft is made from a welded steel tubing, with an Aramid reinforced cockpit section. Its 15 m span wing employs a Carbon-fiber-reinforced polymer spar and carbon sandwich construction. The kit came with pre-molded fiberglass parts. The cockpit was designed to accommodate a pilot of up to 76 in in height and weighing up to 260 lb with parachute.
