The Custom Flight North Star is a Canadian amateur-built aircraft, designed by Morgan Williams and produced by Custom Flight of Tiny, Ontario. The aircraft is based on the Piper PA-18 Super Cub and is supplied as a kit for amateur construction. The North Star features a strut-braced high-wing, a single-seat, a two-seats-in-tandem enclosed cockpit that is 29 in (74 cm) wide, fixed conventional landing gear and a single engine in tractor configuration. The aircraft fuselage is made from welded 4130 steel tubing, with the wing constructed from aluminum sheet and all surfaces covered in doped aircraft fabric. Its 36.3 ft (11.1 m) span wing employs a USA 35B airfoil, has an area of 190.7 sq ft (17.72 m2) and mounts flaps. The wing is supported by "V"-struts and jury struts. The aircraft's recommended engine power range is 150 to 180 hp (112 to 134 kW) and standard engines used include the 150 hp (112 kW) Lycoming O-320 four-stroke powerplant. Construction time from the supplied kit is 1200 hours. The aircraft can be mounted on wheels, floats or skis. By December 2011 the company indicated that 20 examples had been completed and flown.
