The Stoddard-Hamilton Glasair II is an American amateur-built aircraft that was designed by Tom Hamilton and produced by Stoddard-Hamilton Aircraft and later Glasair Aviation as a kit for amateur construction. It was first flown in 1989, and remained in production in 2012.[1][2][3]

Design and development

A development of the earlier Glasair I, the Glasair II features a cantilever low-wing, a two-seats-in-side-by-side configuration enclosed cockpit accessed via gull-winged doors, fixed or retractable tricycle landing gear or fixed conventional landing gear and a single engine in tractor configuration.[1][2][3]

The Glasair II was designed to FAR Part 23 standards and was extensively tested. Its wing has been tested to +10.5g. As indicated by its name, the aircraft is made from fiberglass. Its 23.3 ft (7.1 m) span wing employs a NASA GA(W)-2 airfoil. The wings have an area of 81.3 sq ft (7.55 m2) and mount flaps. The acceptable power range for the Super II RG or Super II FT versions is 160 to 210 hp (119 to 157 kW), with the 180 hp (134 kW) Lycoming O-360 four-stroke powerplant a commonly used engine.[1][2][3][4][5]

The manufacturer estimates construction time for the Super II RG or Super II FT versions as 3000 hours.[1]

The Glasair II was later developed into the Glasair III.[1]

Operational history

By December 2011 there were 1200 examples reported completed and flying making it one of the most successful two seat kit aircraft ever designed.[1][5]
