Set of 4 custom FAA registration number decals suitable for most small unmanned aircraft systems (sUAS) or drones. You are required to register your UAS and display your FAA registration number on your aircraft if it weighs between 0.55 lbs. (250 grams) and up to 55 lbs. (25 kg). These stickers are 1/2″ high by approximately 5″, varying because of font widths. Add 4 phone number decals in the same style as the registration number for $2.00 more.
