Design and development

The Sport Racer features a cantilever mid-wing, a two-seats-in-tandem enclosed cockpit under a bubble canopy, fixed conventional landing gear with wheel pants and a single engine in tractor configuration.[1]

The aircraft fuselage is made from welded 4130 steel tubing. The 22.00 ft (6.7 m) span wing has a wooden structure, covered in doped aircraft fabric and has a wing area of 81.00 sq ft (7.525 m2). The standard engine used is a 230 hp (172 kW) Ford Motor Company V-6 automotive conversion powerplant.[1]

The Sport Racer has a typical empty weight of 1,175 lb (533 kg) and a gross weight of 1,850 lb (840 kg), giving a useful load of 675 lb (306 kg). With full fuel of 30 U.S. gallons (110 L; 25 imp gal) the payload for the pilot, passenger and baggage is 495 lb (225 kg).[1]

The standard day, sea level, no wind, take off with a 230 hp (172 kW) engine is 1,500 ft (457 m) and the landing roll is 1,600 ft (488 m).[1]

The manufacturer estimated the construction time from the supplied plans as 1600 hours.[1]
