Another land mine in AC 91-57A is the establishment of a 400 foot altitude cap as a "best practice." This is not a casual term, it carries a well defined legal meaning, so in other words, the FAA could turn around and say any time you are flying above 400 feet agl you are no longer following a "best practice" and thus are in violation of FAR 91.13 http://www.ecfr.gov/cgi-bin/text-idx...0.1.3.10.1.4.7

So this could effectively end pattern, IMAC, soaring, jets, etc.

BTW - I generally agree that it is less about what you fly and more about how you fly when parsing out the differences between conventional/traditional modeling and other types of flying. Having said that, even if you are flying your airborne camera platform for the pure joy and recreation of that activity, I still feel that is not what this hobby of model aviation is about. It is certainly a hobby, but it is one in its own right separate from what most all of the rest of the AMA memberships has been about for so many years.
