Using Air radios for Surface use is against FCC frequency designation policy. It would also anger any model airplane flyers in the area.
Correct on the Futaba. As far as your other comment goes, 2.4g is 2.4g no matter if it's a surface or air system. That FCC crap is for AM and FM systems which are dinosaurs today. There are people all over using air systems for scalers, crawlers, boats, robots, etc...
