My personal impression is that GadgetGuy is not a fan of AMA. I joined without bothering to read the 200+ documents because $15 for a three-month trial membership seemed reasonable, and having an AMA number and a "Reward if found" phone number affixed to a label on my bird gives the impression that I'm trying to be a responsible operator. And if I have to pop another $5 to the FAA for yet another number to remain legitimate, so be it. I enjoy the hobby and have just picked up a couple of large R/C park model foamies to expand my enjoyment into fixed wings as well. I'm in this for the enjoyment, not the railing against authority that government regs have deemed necessary. After all, regulations in other countries are far more stringent and draconian. Go... Fly your bird(s), stay safe, and go with your personal feelings. But don't try to wag yours in my face.
