Design and development

The aircraft was developed from the two-seat SP-2000 Speed and features a cantilever low-wing, a four-seat enclosed cockpit, fixed tricycle landing gear and a single engine in tractor configuration.

The aircraft fuselage is made from welded steel tubing covered in non-structural fibreglass. Its 8 m (26.2 ft) span wing is built from 6061-T6 aluminum covered in doped aircraft fabric and fibreglass. Standard engines recommended are the 150 to 160 hp (112 to 119 kW) Lycoming O-320 or the 180 to 200 hp (134 to 149 kW) Lycoming O-360 four-stroke powerplants, along with similar Continental Motors, Inc. or auto-conversions. Cockpit access is via gull-winged doors on both sides. Wheel pants are usually fitted.
