The design goals of the Free Spirit Mk II included long range, high speed and a high rate of climb. The aircraft features a cantilever low-wing, a two-seats-in-side-by-side configuration, plus a jump seat in an enclosed cockpit, retractable tricycle landing gear and a single engine in tractor configuration.
The aircraft is made from lightweight pre-molded composites. Its 30.31NaN1 span wing employs a NASA NLF(1)-0215F natural laminar flow airfoil, mounts flaps and has a very small wing area of 86square feet, giving a high wing loading of 25.0 lb/sq ft (122 kg/m2). The cabin width is 44.5inches. The acceptable power range is 150to and the standard engine used is the 2100NaN0 Lycoming IO-360 powerplant.[3]
The Free Spirit Mk II has a typical empty weight of 1250lb and a gross weight of 2150lb, giving a useful load of 900lb. With full fuel of the payload for crew, passengers and baggage is 588lb.
In 1998 the company reported that two aircraft were flying, but by December 2013 only one example remained registered in the United States with the Federal Aviation Administration.
