As a piston-engined helicopter owner, I am extremely eager for the G100UL STC to be extended to rotorcraft airframes (hopefully not just Robinson but Bell, Enstrom, Hiller, Hughes, etc., but thanks Robinson for doing the work) - I will buy the STC as soon as it is available (IFNOR than to support and encourage GAMI) and start using the fuel as soon as it becomes available (in NJ).
