This will go over like a lead balloon with some, but I think all these too easy to fly quadcopters, any of them capable of carrying a camera, should require flight certification and registration/insurance at time of purchase. I don't believe in gun laws, but I do believe in requiring safety classes/licensing/registration. It seems more and more like common sense is lacking and young people don't have elders showing them the way. Maybe I'm just getting old?
The industry is cashing in on these things without regard to what and how they're used, any idiot can buy one and basically do whatever they want. It's cool technology and I appreciate what they're capable of and the people that use them responsibly, but it's going to get out of hand without some sort of regulation.
No need to regulate the rest of the RC world as the commitment required to learn to keep them airborne will deter those lacking the common sense to own one.
These after the fact laws won't deter the idiots from purchasing them and doing something stupid.
