Some of us have been watching this coming since 2007, when the first ARC committee pretty much shut the AMA out of any activity that would permit them to provide input. OTH, the AMA was a little slow to catch on in spite of what some had been telling them for a year before the ARC thing started.
The depth of what the FAA is about to attempt is far more encompassing that many understand. Those flying "commercially" will include sponsored RC pilots for manufacturers, people receiving cash or products for contest wins, hobby shop owners flying at local sites as advertising, multirotor and small heli flyers that use their craft for aerial journalism and cinematography, and anyone one flying pretty much anything that provides any form of compensation, be that cash, product, exposure, or forms of consideration.
Each of you has an opportunity to do something about it, and unfortunately that will require each of you to
do something. Passive protests like posts on an RC forum will not benefit you at all. Despite their lack of teeth, join the AMA. I don't care what pet peeve you might have with the AMA, I have a few of my own but now is not the time to think you can stand alone and make something happen. You need to be part of an organized group that politicians can view as a voting group. Even if you're not old enough to vote, your parents are. Next, look around for other groups you can join that probably share your views. One that is primarily intended for multirotor professionals is at
www.acuas.org
They are free and they accept members from regular RC that don't fly professionally because they understand that RC professionals started as RC amateurs. Their intent is to band as many people together as possible to act as a larger voice when the time comes to speak out. They'll also assist with form letters to be used for mass e-mails to representatives.
I've been in this hobby for a very long time. I also fly multirotors and shoot aerial video. I used to fly military grade UAV's. In close to 50 years of these activities I've never seen a power grab such as what is now in play. It does not have to happen, although there are some that believe total control is the only way people should be able to live their lives. The way to put a stop to it is by using the system as it was designed to be used. When the FAA NPRM comes out be ready to respond, in writing, rationally. Use the various political action groups like the AMA, ACUAS, AUVSI, Drone Pilot's Association, and others, to act as your proxy in lobbying the government bodies that will be in play.
For those of you that might have any doubt, 3D aerobatics will be viewed as dangerous and reckless operation of an aircraft. So don't sit back and think it won't affect you. if you fly thermal duration gliders you can forget every performing a multi hour thermal duration flight ever again. You won't be able to get high enough in a thermal to really take advantage of it. you jet jock are SOL. All those high speed passes will have a speed limit. Fly FPV? You won't anymore and all that expensive stuff you bought to do it will be instantly worthless.
