, far too many have ignored those guidelines as "just suggestions to be ignored" and done anything they want. It seems the FAA has realized that their "guidelines" aren't taken seriously (or are abused) so here come the "rules".
Anything they come up with now will also be ignored. Not by the AMA but most of its members and almost all of the non members. Only those who know about the rules will likely comply and the AMA can shout from the rooftops and most will not listen. Perhaps that is why the FAA is reluctant to regulate models.
