The Feds want to register all of te quadcopters. It is nothing more than a source of REVENUE for them, and an exercise in CONTROL.
The story of fire helicopters being grounded is false. It is a lie. In order to get people to comply with some infringement on your Rights, the Feds must first set up in your mind the NEED to infringe on that right. Gun Control is a prime example, in which the Feds CREATE the problems and then tell us, "If you want to be safe, you need to forget about your Rights!"
Aw Geez, don't get me started!
Before you rush out to place your N-number on your quadcopters, think about this. If you are flying your q/c and someone SEES your N-number on it, they can then place YOUR number on THEIR quadcopter, and fly it into a power line or something. When the Feds investigate, guess who's door they'll be knocking on. Now YOU have to convince government zombies that it was not YOUR q/c that set the town on fire, or YOUR q/c that was peeking through a window.
People have been flying R/C airplanes and helicopters for decades. Ask yourself, "WHY NOW? Why does the gu'mint suddenly feel the need to force everyone to REGISTER their q/c?" The answer is found in the CAMERAS. The gu'mint doesn't like you having the ability to spy on THEM.
Frankly, when I first saw a q/c with a live down link camera, my first thought was, "These things will be buzzing outside of the girls dormitories at USC!"
They are much easier to fly than R/C airplanes, and WAY easier than flying a R/C helicopter. I can think of many good uses for them.
