I don't think the FAA registration has anything to do with the AMA's membership worries. As I stated above, the hobby in general is in decline. As the hobby goes, so the AMA goes unless it shifts its focus. Part of it is cultural- a lot of the younger hobbyists don't want to be part of a group. Yet oddly enough groups are forming organically as people figure out it's really boring to fly drones by yourself. I agree the paradigm of club fields and AMA sanctioning won't work with the drone crowd. It's still a bit early to know what will work, but history shows that building community is the key. That's what got the AMA to where it is now, and that's what will carry it into the future if it is to survive.
