Don't get caught doing that Don. I had a friend who did that and was fined by the FAA. (I don't know how they found out) But he did not have a Commercial Pilots license and did some commercial real estate work... and they got him.
I looked at taking that test because people ask me all the time to do commercial work, and the test is bogus... how the hell would I know what is the proper way to weigh load a commercial airliner?
I've been reading up on the law and know the amateur restriction, both from myths and actual reading the regs. I am wondering, though if the law restricts end use or whether you do work for hire. I know in some cases as long as I'm not paid, commercial work for hire does not apply but in the case of the FAA, not sure. The wording was quite vague. There are agencies who buy amateur drone video and they resell it.
Locally there are over a dozen video production companies using drones for their video assignments and none of them are commercial pilots. I know these guys. They are very good but not exactly "legal"
But according to the experts, in August 2016, the FAA clarified the rules a bit and now allow you to get licensed as a "professional drone photographer" under Part 107 of the rules. You have to take a simple written test on knowledge of maps and rules and regulations, some compare to a driver's learner's permit in complexity. So a few hours of study and you can pass the test. Probably easier than a concealed weapons license. But they charge $150 for the exam and license. So, likely, Scott, your understanding may be dated now.
Personally, I am not really excited about going back into the video production business from my fun in retirement. I don't need the money and don't need the recognition in this area. 22 years of it and I just like playing with what I want to, when I want to, and not having to meet deadlines.
BTW- those who have been caught violating illegal air space, have been fined $250 which seems to be quite common fine. These have been all from complaints of private land owners who had their privacy invaded or other well known air space violations, like flying over a military base or airport. It isn't that there is an enforcement division in the FAA that is out looking to fine drone pilots for $250 a pop.
I might have said before my biggest disappointment is no drones in National Parks and some State Parks. That greatly limited my amateur use, such as the Grand Canyon and a few other parks.
