OK, but that page is complete nonsense. And it is not what this thread was originally about. Take the part about notifying an airport if you are flying within five miles. No law or regulation requires that, and they can't (yet) possibly penalize anyone for not doing it. The five-mile thing comes from the text of the 2012 law on FAA regulations, which purports to limit what they can regulate. It imposes no duties whatever on modelers. What we have to worry about is not this nonsense, but what the FAA will do when it writes the regulations, which will impose limits on us. So far, the only real clue about what those limits will be is their "interpretation," which is far from encouraging.
