Drone Classes by FAA Rules in 2026: C0 to C4 Explained

The FAA spent five years rewriting the rules that govern small drones and the result, as of 2026, is a five-class system that decides where you can fly, what paperwork you need, and what your aircraft must broadcast. The classes run from C0 (the smallest, under 250 grams) to C4 (over 25 kilograms, professional cinematography and industrial work). Knowing which class your drone falls into is the difference between flying legally on a Saturday morning and watching a Part 107 violation letter arrive in the mail. This guide walks through each class, what it weighs, what it can do, and what you can legally do with it under the rules in effect right now.

Class C0: Under 250 grams

Class C0 covers drones with a maximum takeoff weight under 250 grams. The flagship examples are the DJI Mini 4 Pro (249 grams), Autel Nano+ (249 grams), and the Potensic Atom 2 (245 grams). Manufacturers obsessively engineer to stay under the 250-gram threshold because the regulatory burden drops sharply below it.

Recreational C0 flyers do not have to register the drone with the FAA. Commercial operators under Part 107 still must register, regardless of weight. Both groups must pass the TRUST test (recreational) or the Part 107 knowledge exam (commercial). Remote ID applies to commercial flights and to most recreational flights outside FRIAs.

C0 drones are restricted to 400 feet above ground level (AGL), daylight or civil twilight operation (with anti-collision lights at night), and within visual line of sight. They cannot fly over uninvolved people unless they meet Category 1 operations over people rules, which most do because of the weight class.

Class C1: 250 to 900 grams

Class C1 sits in the soft-middle zone where most prosumer cameras live. The DJI Air 3S (720 grams), Autel EVO Lite+ (835 grams), and DJI Mini 4 Pro Plus battery (335 grams) all land here. The class is not formally codified by the FAA the way EASA codifies it, but the weight bracket maps to a common regulatory tier.

C1 drones must be registered with the FAA, must broadcast Remote ID outside FRIAs, and follow the same 400-foot ceiling as C0. The practical advantage of C1 over C0 is wind resistance (most C1 drones handle gusts up to 27 mph versus 24 mph for C0), sensor size (1-inch or four thirds sensors are common at this weight), and flight time (45 minutes is normal).

For wedding photographers, real estate creators, and travel cinematographers, C1 is the sweet spot. The camera quality is meaningfully better than C0, the airframe is still light enough to throw in a backpack, and the regulatory burden is lighter than C2.

Class C2: 900 grams to 4 kilograms

This is the working professional class. The DJI Mavic 3 Pro (958 grams), DJI Air 3S Pro (920 grams), Autel EVO Max 4T (1,620 grams), and Skydio X10 (2,500 grams) all sit in C2. Cameras carry triple-sensor arrays, mechanical shutters, ProRes recording on some models, and obstacle avoidance from every angle.

C2 drones must be registered. Remote ID applies in all standard operations. The 400-foot ceiling still holds, but C2 drones are commonly waived to higher altitudes for inspection work because the larger airframes carry redundant systems that reduce risk. C2 is the typical entry point for commercial inspection, mapping, and high-end cinematography under Part 107.

Setback rules differ by state and city. California, Florida, and many National Park Service properties impose stricter rules on drones above 1 kilogram. Always check the local ordinance before launching a C2 drone in a populated area.

Class C3: 4 to 25 kilograms

C3 is where things get serious. The DJI Inspire 3 (3.99 kilograms, just sneaking in), Freefly Alta X (10 kilograms), and DJI Matrice 350 RTK (9.2 kilograms) handle cinema cameras, multispectral payloads, and LiDAR sensors. These drones cost between 10,000 and 60,000 dollars, fly for 45 to 55 minutes, and carry the kind of redundancy you need when a failure could hurt someone.

C3 operations almost always require Part 107 plus waivers. The 400-foot ceiling can be waived for tower inspection, antenna work, and cinematography. Flight over people requires Category 3 operations or higher, which most C3 drones cannot meet without a parachute system like the ParaZero Safe Air.

Insurance jumps significantly at this class. A typical hull and liability policy for a Freefly Alta X runs 2,000 to 4,000 dollars per year. Most cinema rental houses require a million dollars of liability coverage as a minimum.

Class C4: Over 25 kilograms

Class C4 is industrial and military territory. Agricultural spray drones (DJI Agras T50, XAG P100 Pro) and heavy-lift cargo drones live here. The FAA treats anything over 55 pounds as requiring a Part 91 exemption, not standard Part 107 coverage. These operations need a dedicated exemption package, a registered ground crew, and almost always a visual observer.

If you are flying a C4 drone, you are running a fleet, not a hobby. The certification path is closer to commercial aviation than to recreational drone flight.

Remote ID and the broadcast requirement

Remote ID is the digital license plate for drones. Since September 2023, all drones flown outside a FRIA must broadcast their location, the operator’s control station location, and a serial number that ties back to the registration. Most drones built after 2022 ship with Remote ID baked into the firmware. Older drones can add a Remote ID module strapped to the airframe.

The broadcast happens over Wi-Fi or Bluetooth and is readable by anyone with the FAA’s app or a compatible receiver. Law enforcement uses the same broadcast to identify drones flying in restricted areas.

Where this leaves you

If you are buying your first drone in 2026, start with a C0 model. The DJI Mini 4 Pro is the default recommendation because it cuts through 90 percent of the regulatory friction while still delivering 4K HDR video. Once you have logged 50 hours, decide whether the work justifies stepping up to C1 or C2.

For commercial use, the Part 107 certificate is non-negotiable. Pair it with a drone photography license overview and our drone batteries guide before you put a drone in the air on a job.
