I'm going to be listing soon on my local Craigslist. I got my answer regarding the FAA registration. (Just take off the sticker and put one on my new Mavic.) But, what about DJI, do I need to transfer ownership of the drone? I bought it from Amazon on July 17, so it I'm guessing there is some degree of warranty coverage still on it, but I don't recall "registering" the sn with dji.
