you got me. Seems the AMA is responsible for a couple of things;
1) Excellent record keeping of statistics from competition flying of all kinds, from all across the USA. (gotta have stuff for the magazine you know)
2) This mess we are in right now! I am still not convinced that any branch of the government, has any desire to regulate " line of sight" flying of any type. I mean really, how far can you go.
Looks like all other guidlines, measurements, safety requirements etc. are merely suggestions, not etched in stone rules. When have you ever heard of the AMA repremanding anyone for flying to high, far or fast?
Oh, one more thing I'm starting to feel they are responsible for;
3) Using MY membership dues to fund a battle for regulations in MY hobby!!??
What past AMA actions are you referring to?
