All RC fliers are essentially advertising for the industry when they fly on their club field. Is the FAA going to check on every flier to try to see if he's being compensated? lol
From what I've heard, the FAA is very much understaffed and unless something very drastic happens, I don't think we will hear a peep from them. They have much bigger fish to fry than us flying our toys.
At least our fixed wing toys.
