You do need to be aware that the AMA has no authority that people do not explicitly give it. The AMA cannot require you to be a member, whether you fly a rubber powered $2 free flight airplane or a 150" Giant Telemaster.
Joining the AMA gets you insurance, and allows you fly at a lot of fields that require that you be an AMA member (which is mostly about the insurance.) Outside of these clubs, you may have a hard time finding a place to fly a large glow or gas powered airplane unless you or a friend own a lot of land. It also does help promote and protect the hobby, and gets you a spiffy magazine each month.
Most people don't bother to join the AMA if they just fly small electric planes, because you can usually fly these at most local parks (the local laws usually don't prohibit, and they usually don't bother people.) Anything glow powered, or larger electric planes tend to make more noise and can upset your local law enforcement if you fly it at a park, for example.
The AMA rules are not laws. But they're pretty good guidelines, for the most part, for whatever you're flying.
| I'd love to fly my electric on the field near my office on lunch | break. The closest club field is 30 minutes away.
Then do so, assuming that it's permitted by the local laws, and the electric isn't so large as to really be dangerous. Don't fly it near people, no matter how small it is -- even a small Speed 400 motor and prop can give you a nasty gash.
If there's a field (or even another guy flying his small electric) within 3 miles or so, you need to ensure that you're not using the same frequencies, but if they're 30 minutes away, you should be safe.
