Design and development

The Mark II features a two-seats-in-tandem open cockpit with an optional bubble canopy, fixed conventional landing gear and a single engine in tractor configuration. The Mark II was intended as a two-seat trainer version as a companion to a planned single-seat competition version.[1]

The aircraft is made from welded steel tubing with the airframe covered in sheet aluminum. Its 25.5 ft (7.8 m) span wings employ a NACA 23012 airfoil and each has a single torsional spar. The standard engine recommended was a 220 hp (164 kW) Franklin Engine Company powerplant.[1][3]

The aircraft has an empty weight of 1,200 lb (540 kg) and a gross weight of 1,540 lb (700 kg), giving a useful load of 340 lb (150 kg). With full fuel of 18 U.S. gallons (68 L; 15 imp gal) the payload is 232 lb (105 kg).[1]
