Not a single hobby drone has been registered thus far . The FAA is registering hobby based drone pilots and not the drones themselves . The FAA has our names and addresses , and have no database covering which particular drone(s) we are flying . My drones are pretty much exclusively models of WW1 and WW2 era airplanes , your drones may well be FPV multirotor types , or RC Zeppelins , and to the FAA we're both drone pilots with no distinction being made as to the exact drone each of us happen to be piloting .

It's my belief that when folks go citing the Constitution in their complaints of government overreach , it's the maintaining of a database that causes them the most consternation . When one stops to realize that the database was began with the very first Social Security number issued and has grown exponentially in the modern electronic age , the precedent is well established of the feds keeping lists of citizens . Now , citing the possible nefarious use of our leisure time toys , the fed's view is that the perfect excuse to maintain a database of us has been established , even though the bad guys won't be the ones with their names registered with the FAA . Honestly I don't worry too much about government lists , having worked for the government at one point in my life they already have all the info on me they'd ever need
