An anonymous reader writes: The U.S. Federal Aviation Administration has finally unveiled its new drone registration rules. Starting on 21 December, all newly-purchased drones between 250 grams (.55 lbs) and 25 kg (~55 lbs) must be registered before their first flight. Owners of drones purchased before that time must register by 19 February 2016. The FAA will charge $5 to register the drones, though the first month of registrations will be free. "Make no mistake: unmanned aircraft enthusiast are aviators, and with that title comes a great deal of responsibility," said U.S. Transportation Secretary Anthony Foxx. "Registration gives us an opportunity to work with these users to operate their unmanned aircraft safely. I'm excited to welcome these new aviators into the culture of safety and responsibility that defines American innovation." There is also an age requirement: kids under the age of 13 will not be allowed to register a drone by themselves.
