Kraus-
Of course not. AMA can only control members of clubs that that have submitted to AMA mandates in exchange for the privilege of buying insurance. Some people get their knickers knotted up when I say that, but I've yet to hear from anyone of any other sensible reason for having an AMA club charter (speaking as non-competitive flyer in a sport flying oriented club - there may be good reasons for clubs comprised of competition oriented folks that I'm unaware of).
I doubt that the 85,000 or so AMA members that belong to AMA clubs represent more than a single digit percentage of aeromodelers in the country. If you don't want your flying to be controlled by AMA, just go with the flow......
