This is a 3-step registration. To fly at the field, you only need a Limited Recreational Operations registration, which is $5 for 3 years. This registration is good for all your UAS, no matter the number that you have. As of 2015 the FAA considers anything that flies and weighs over .55lbs an UAS (Unmanned Aircraft System) and must be registered.
