I agree that the notion of tests and a database of signed documents for each toy sold is more than just a wee bit "out there" , in a country where we don't have enough USDA inspectors to monitor even half the meat and produce that goes into our dinners each night . Our roads and bridges are literally falling apart and the electrical infrastructure is totally inadequate for the upcoming revolution of the "plug in car" . And these guys think the govt. is gonna throw in the $$$ required to set up and maintain a database of toys , rather than fix the real and pressing problems affecting millions each day ?

The sane approach would be that page one of the instructions that come with all flying toys has a brief run down on the safe operation of that toy and any applicable laws regarding it's use . That way , just the fact of owning the toy means that a set of safe operating guidelines came with it , and it is the fault of no one but the toy's operator if the guideline isn't read or adhered to .

Step one = RTFM

Step two = use it safely and have fun

Step 3 = Ignorance of the law is not now and has never been a successful defense ......
