If you use your drone for fun, you may be eligible for a refund of your $5 registration fee. The Federal Aviation Administration started a drone registration program in 2015, but the US Court of Appeals decided the registration rule violated the FAA Modernization and Reform Act on May 19, 2017.
To get the refund and have your registration record removed, drone hobbyists can fill out this form. Drone owners are required to certify their UAS was only used for recreational purposes.
The Consumer Technology Association reported that in the U.S. alone, last year people bought 2.4 million hobbyist drones. Data from The NPD group found U.S. drone sales more than doubled in the 12 months ending in February 2017, with a 117 percent increase year-over-year.
