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.
