Design and development

The aircraft was designed to comply with the Australian rules for amateur-built aircraft. It featured a cantilever low-wing or optionally strut-braced high-wing, a six-seat enclosed cabin, fixed tricycle landing gear and a single engine in tractor configuration.^[1][2][3]

The SP-6000's fuselage was intended to be made from fibreglass with the wing constructed of 6061-T6 aluminium, with S-glass control surfaces. It was to be powered by a Corvette LS3 automotive engine conversion, a 180 to 200 hp (134 to 149 kW) Lycoming IO-360 four-stroke aircraft engine or a turboprop powerplant. The cabin was planned include an optional toilet and galley.^[1][3]

The initial design was unpressurized, but the company was considering a follow-on pressurized version. The high wing version was to have a cruise speed of 145 kn (269 km/h), while the low-wing version would have cruised at an estimated 250 kn (463 km/h).^[3]
