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 I, 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 fibre construction. First kits are due to be released by July 2018.
