I've come to the conclusion that I will do a better job of labelling my second drone than the first, which I just sold. Previously, I thought the FAA registration ID was enough. But now, after spending more time on the forum, realize the FAA ID, contact phone number and reward statement are in my best interest, and will facilitate the return of my bird should it ever stray and get lost. To date, never have crashed or lost a drone, but I want to be prepared.
