It's a difficult issue. One one hand you have a very useful technology: An inexpensive. slow-flying/hovering stable platform that is great for photography or surveying or whatever. I personally would love to invest in some of this stuff to make better flying movies. On the other hand, you have an incredibly high rate of adoption by the general public who are completely oblivious to the existence of regulated airspace, and lack the emotional investment of having their real butts up in the sky.
In past 50 years, radio controlled hobby flyers have steadily grown in numbers, spurred by the same technological advances that have helped pretty much everything else, but until now those RC aircraft required some actual skill and dedication to enjoy. If you've ever flown a RC plane, they are not easy to control due to the shift in spatial orientation your brain has to adapt to. It's hard even if you're a great pilot of real airplanes. Have you ever tried flying a RC multi-rotor? There is absolutely nothing to it; it's 99% software, and there's no urgency to react because no airspeed or velocity required to stay aloft. It's finally the thing that has apparently put the radio control hobby over the top, and all the old neurotic enthusiasts (like me) now belong to the age of The Before.
I think the American Modelers Association must be shitting their collective pants because the FAA has been forced to act. The whole deal in their recent ruling about stating that violations via UAV would result in violations against pilot certificates (if possessed by the UAV operator) was game-changing, at least for us who dabble in both.
But what does it mean for Joe Mall-rat? Nothing. Some guy posted a video on another non-aviation site last year of GoPro footage taken from his DJI Phantom, of flying in IMC (actually dense scattered, in-and-out) above 2,000 AGL. He was heavily chided by others but the takeaway is that the technology exists to make this easy and there is no end to the number of ignorant individuals who will take advantage.
Solution? Shit, I dunno. With our lives at stake, I'm not necessarily opposed to industry reform to require transponders or GPS altitude ceilings via software (DJI might already have this.) The trouble is, it's a modeling/kit-builder's/hackers' hobby and there's no way to enforce it other than with some flagship violations and punitive enforcement. Freedom is great right up until your stupidity threatens my and/or my family's life.
In responsible and knowledgeable hands, they are great tools and I wouldn't hesitate to fly in close proximity to one in a controlled scenario like filming. But when Jimmy Legomaniac initiates his decent out of the clouds from the comfort of his desk in between monitoring Facebook posts... gotta draw the line.
