Sorry I put this in the P4P area. Should be a quick answer I hope. LOL. But I registered over a year ago now. I've been through 3 diff birds since then. I thought that you only needed to register once and if did not matter how many aircraft you have or have had. That you just got a number that mean't it was you and you would put that number on any and all drones that you may own. I am telling another friend to go and get register now and she is seeing that there are so many sites doing the registration now and charging 10-24 bucks and want drone info and serial numbers. FAA. gov is not doing that. But I still don't see where FAA says anything about having to provide each drones individual info like make and serial number. So what is the deal if you sell several drones and have more than one drone? Thought FAA registration was just basically registering yourself and not the ind drone? Thanks for the help!
