Do I Need to Register the DJI Mini 4 Pro?
At 249 grams the DJI Mini 4 Pro sits one gram under the FAA registration threshold. Recreational flyers do not have to register it — but that changes the moment you add prop guards or fly for work.
Quick answer: do I need to register the DJI Mini 4 Pro?
Recreational flying: No — registration not required
Its 249 g takeoff weight is below the 250 g (0.55 lb) threshold in 49 USC 44809, so a recreational flyer does not register it.
Part 107 (any business use): Yes — registration required
Part 107 has no weight exemption. Every aircraft flown under Part 107 must be registered, even at 249 grams.
The DJI Mini 4 Pro is the most common drone in the United States that lands on the right side of the FAA's registration line. Its 249-gram takeoff weight is not a coincidence: DJI engineered the entire Mini series to stay one gram under the 250-gram threshold that triggers registration for recreational flyers. That single gram is the difference between filing paperwork and simply flying.
The catch is that weight is only half the story. Registration depends on why you are flying as much as on what you are flying. Fly the Mini 4 Pro purely for fun and the 249-gram exemption applies. Fly the same aircraft for anything that benefits a business — a real estate listing, a paid roof inspection, a sponsored video — and you are operating under Part 107, where the weight exemption does not exist.
This page covers both cases, explains what the built-in Standard Remote ID does for you, and flags the accessories that quietly push this drone over the line.

August 2026
Checked against the manufacturer specification
Weight verified August 2026 against the DJI Mini 4 Pro specifications. Manufacturers occasionally revise specifications, so we re-check this page periodically.
- The 249 g figure is the takeoff weight with the standard Intelligent Flight Battery, propellers and a microSD card installed. It is not the weight of the airframe alone.
- The Intelligent Flight Battery Plus, sold in some regions, raises the takeoff weight above 250 g. If you fly with that battery, treat the aircraft as a registered drone.
What you need to fly the DJI Mini 4 Pro legally
- 1
Confirm which rules you are flying under
Recreational flying means flying strictly for fun, under the exception in 49 USC 44809. Anything that furthers a business — even indirectly, even unpaid — falls under Part 107.
- 2
Take the TRUST test (recreational only)
Every recreational flyer must pass the free Recreational UAS Safety Test, regardless of drone weight. There is no 250-gram exemption for TRUST. Save the completion certificate; it is not reissued.
- 3
Register if you fly under Part 107, or add weight
Part 107 operations require registration of the aircraft. Recreational flyers only register when the takeoff weight reaches 250 g or more.
- 4
Mark the registration number if you register
The FAA number must be legible on the exterior of the aircraft. On a Mini-sized drone most pilots use a small label on the battery bay or the underside of the arms.
- 5
Leave Remote ID switched on
The Mini 4 Pro broadcasts Standard Remote ID from the aircraft. Keep the firmware current and do not disable the broadcast.
- 6
Check the airspace before every flight
Use B4UFLY or a LAANC app. Controlled airspace requires authorization for both recreational and Part 107 flights, whatever the drone weighs.

What if you add accessories?
Prop guards push the Mini 4 Pro over 250 grams
The 249-gram rating leaves exactly one gram of margin. Almost any accessory that stays attached during flight eliminates it. The DJI propeller guard set for the Mini 4 Pro adds roughly 30 to 40 grams, which puts the aircraft in the 280 to 290 gram range — comfortably above the threshold.
The FAA looks at the weight of the aircraft at takeoff, including everything attached to it. If your drone weighs 250 g or more when it leaves the ground, it must be registered and marked, even if the airframe on its own weighs 249 g.
- Propeller guards: roughly +30 to 40 g — registration required
- Intelligent Flight Battery Plus: pushes takeoff weight over 250 g — registration required
- Strobe or anti-collision light: 10 to 20 g — over the line on its own
- Landing gear extensions and filters: a few grams each, and they add up
Not sure where your setup lands? The drone weight checker converts grams, pounds and ounces and tells you whether the result crosses the threshold.
Where you can and cannot fly it
- Stay below 400 feet above ground level and keep the aircraft within visual line of sight.
- Controlled airspace (Class B, C, D and surface E) needs LAANC authorization before you fly, even at 249 grams.
- National parks prohibit launching, landing and operating from park land. Stadiums during major sporting events, Washington DC's Special Flight Rules Area and active temporary flight restrictions are off limits.
Airspace rules are identical for every drone, light or heavy. Our pillar guide Where can I fly my drone? covers airspace classes, LAANC authorization, national parks and temporary flight restrictions in detail.
DJI Mini 4 Pro registration FAQ
Do I need to register the DJI Mini 4 Pro with the FAA?
Not for recreational flying. The Mini 4 Pro weighs 249 grams at takeoff, which is under the 250-gram FAA registration threshold. If you fly it under Part 107 for any business purpose, registration is required regardless of weight.
Does the DJI Mini 4 Pro have Remote ID?
Yes. The Mini 4 Pro has Standard Remote ID built in and broadcasts its identification, location and takeoff point directly from the aircraft. No external broadcast module is needed.
Do prop guards mean I have to register my Mini 4 Pro?
Yes. Propeller guards add roughly 30 to 40 grams, taking the takeoff weight over 250 grams. Once the aircraft weighs 250 grams or more at takeoff, recreational registration and exterior marking are required.
Do I still need the TRUST test for a 249-gram drone?
Yes. TRUST applies to every recreational flyer in the United States, with no weight exemption. It is free, takes about 20 minutes, and you must carry the completion certificate when you fly.
Can I fly the Mini 4 Pro commercially without registering it?
No. Commercial flights fall under Part 107, which requires aircraft registration at any weight, plus a Remote Pilot Certificate for the pilot.
