Before you fly, there are three things the FAA requires of recreational pilots in the US. They take about an hour total and are not optional.
FAA registration
Any drone weighing 0.55 lbs (249g) or more must be registered with the FAA. Registration costs $5 and is valid for 3 years. You register at FAA DroneZone, receive a registration number, and must display it on the drone. The DJI Mini 4 Pro comes in at exactly 249g and requires registration. The original DJI Mini 3 is 248.5g and technically does not, though registering voluntarily is not a bad idea since it takes 10 minutes. If your drone is under 250g, you still need to pass the TRUST test.
The TRUST test
The Recreational UAS Safety Test (TRUST) is a free online safety test required for all recreational pilots, regardless of drone weight. It takes about 30 minutes and you cannot fail: it is educational rather than scored. Take it at an FAA-accepted provider and keep the completion certificate on your phone when flying. Most pilot apps (DJI Fly, Aloft) let you store it in the app.
Remote ID
All registered drones sold after September 2023 are required to broadcast Remote ID: a real-time signal that identifies the drone and the pilot's location. DJI drones sold since late 2023 have Remote ID built in and enabled by default. If your drone predates this requirement, you need either a Remote ID broadcast module or an FAA-approved Remote ID declaration (limited to a fixed flying site you register with the FAA). Check your specific model's Remote ID status in the DJI Fly app under safety settings.
Battery and gear prep
Charge your drone battery and controller battery fully the night before. Consumer LiPo batteries reach 100% charge in 60 to 90 minutes via the charging hub. Store batteries at around 50% charge when not flying for more than a few days: most DJI batteries have a self-discharge feature (called auto-discharge or battery management mode) that will bleed down to 60% storage charge automatically after about 10 days if you do not fly. For your first flight, also charge your phone and download the DJI Fly app or the relevant control app before you leave home, not in the field.
