Design and development

The Glasair III is an all-composite cantilever low-wing monoplane. It is an improved variant of the earlier Glasair II with a retractable landing gear and powered by a 300 hp (224 kW) Lycoming IO-540-K1H5 engine. It has two seats side-by-side with dual controls. The aircraft can be fitted with wing tip fuel tanks.[2][3][4] Since the purchase of Glasair II and III aircraft by Advanced Aero Components in September 2017, the Glasair II and III airframes have been substantially upgraded and are to be reproduced in all-carbon-fiber construction. The kits have been rebranded as G2 Heritage and G3 Heritage.
