What is a park flyer, it's in the eye of the beholder. The AMA made their definition, which is supposed to be liberal, no different then their liberal position on the shooting of projectiles at RC aircraft, as long as the AMA supports it, the insurance supports it, then you should support it. No matter where the AMA put their own definition of "Park Flyer" those same people would have found a reason to complain about it. But isn't about time you try to support a not for profit organization ... for once.
