Drones Under 250 g in Poland: Really No Paperwork?

Where the 250 g Limit Comes From

The 250 g figure appears several times in drone rules, and each time it means something different. EU Regulation 2019/945 assigns drones under 250 g to class C0. ULC requires online training and an exam from anyone flying a drone heavier than 250 g. The Polish Aviation Law imposes mandatory liability insurance on operators of drones from 0.25 kg to 20 kg. The 250 g limit therefore exempts you from some formalities, but not all of them.

Manufacturers design their most popular drones just below this threshold. In the drones catalogue the DJI Flip, DJI Lito X1 and DJI Mini 4 Pro are listed at 249 g, and DJI gives 249.9 g for the DJI Mini 5 Pro.

What Still Applies Under 250 g

Costs as of 16 October 2026.

Registration: the Camera Decides, Not the Mass

ULC names two independent reasons for registration in the open category. The first is a take-off mass of 250 g or more, or impact energy above 80 J. The second is a sensor able to capture personal data, such as a camera. Either one is enough. Almost every recreational drone has a camera, so registration covers even the lightest models, such as the DJI Neo 2 (151 g) or the HOVERAir X1 PRO (191.5 g).

Registration at drony.gov.pl is free. The operator number goes on every drone, usually as a sticker. Only drones under 250 g without a camera or other personal-data sensors, and toys under Directive 2009/48/EC, are exempt. We describe the procedure in “Drone Registration and the A1/A3 Exam in Poland (2026)”.

The Exam: Optional but Recommended

For a C0 drone or a drone without a class under 250 g, reading the manufacturer's manual is enough. ULC and EASA nevertheless recommend the free A1/A3 training and exam. Having passed the exam also helps when the drone crosses 250 g in another configuration.

Insurance: Voluntary Only Below 250 g

Mandatory liability insurance covers operators of drones with a take-off mass from 0.25 kg to 20 kg. Below that limit insurance is voluntary. The Financial Ombudsman and local guides still recommend it, because without a policy the operator pays for any damage out of pocket. Details in “Mandatory Drone Liability Insurance in Poland Since 13 November 2025”.

The Real Take-off Mass, Not the Number on the Box

The main trap is the gap between the catalogue mass and the mass of the drone in the air. ULC explains it using the DJI Mini 5 Pro. The standards under which a manufacturer assigns a drone to class C0 allow a take-off mass deviation of ±3%, about 7 g. That tolerance applies only to the class. The insurance law states the 0.25 kg limit directly and allows no margin.

Three things most often push the mass up:

• A heavier battery. On the DJI Mini 5 Pro the standard battery weighs about 71.2 g and the Plus battery about 117 g, roughly 46 g more. DJI states plainly that a C0 drone fitted with the Plus battery exceeds the C0 mass threshold. The same model in the Fly More Combo Plus is C1-certified. On the Lito X1, class C1 likewise applies to the version with the Plus battery.
• Accessories. Propeller guards, mounts, lights or filters can push the mass above 250 g. The pilot's and operator's obligations then change.
• Inconsistent data. For the FIMI MINI 3 the manufacturer states about 245 g, while the shop x-kom lists 250 g. According to a Maison du Drone test, the drone weighs about 265 g with the Plus battery (3,100 mAh).

If precision matters to you, weigh the drone in its flight configuration. ULC cites the recommendation of Poland's Central Office of Measures (GUM) to use verified non-automatic scales for an accurate reading.

What Changes Above 250 g

A drone that weighs 250 g or more in a given configuration loses the exemptions for light drones:

1. the pilot needs a passed A1/A3 exam,
2. the operator must hold liability insurance of at least 50,000 SDR; flying without it carries a PLN 4,000 (≈ EUR 915) fine,
3. a class C1 drone must broadcast Remote ID, and the operator number is entered in the app,
4. the A1 rules for C1 apply: overflights of uninvolved people should be kept to a minimum.

We explain the difference between C0 and C1 in “Drone Classes C0–C6 and Subcategories A1, A2, A3 Explained for Buyers”.

Mini 4 Pro, Mini 5 Pro, Lito X1: What to Check When Buying

• DJI Mini 4 Pro: according to DJI's data, the Plus battery for this model is not sold in Europe. In Europe the model is offered in class C0.
• DJI Mini 5 Pro: the Fly More Combo contains a C0 drone, the Fly More Combo Plus a C1 drone. DJI states 36 minutes of flight with the standard battery and 52 minutes with the Plus battery. Here, longer flights mean extra paperwork.
• DJI Lito X1: class C0 with the standard battery, C1 with the Plus battery.

When buying, check the class of the bundle, not just the model name.

Rules That Apply to Every Drone

Low mass does not exempt you from the flight rules. A sub-250 g drone flies within visual line of sight, no higher than 120 m above the ground, not over assemblies of people and within the limits of geographical zones. Before every flight you file a check-in in the DroneTower app, regardless of drone mass. In zone EP R134 on the border with Belarus and Ukraine no civil drone may fly at night (as of 16 October 2026). The minimum pilot age is 14. We cover where you cannot fly in “Where You Cannot Fly a Drone in Poland”.
