How to Register a DJI Mini 2 in the UK

DJI Mini 2 Specifications

The DJI Mini 2 was the drone that popularised sub-250g flying in the UK. Although discontinued by DJI, it remains widely available through second-hand marketplaces and is still a popular choice for budget-conscious hobbyists entering the hobby.

At 249g, the Mini 2 sits right at the boundary of the sub-250g category. Despite being an older model, its 4K camera and OcuSync 2.0 transmission system still deliver solid results for recreational aerial photography.

Registration Requirements

Whether you bought your Mini 2 new, second-hand, or received it as a gift, the registration rules are identical. UK drone registration is tied to the pilot, not the drone itself.

Flyer ID — Mandatory

• Required for every drone pilot in the UK, no matter the drone weight or how you acquired it
• Free online theory test at register-drones.caa.co.uk
• 20 multiple-choice questions on airspace, safety, weather, and privacy
• Pass mark: 16 out of 20
• Renewed annually at no cost
• Minimum age: 12 years old

Operator ID

• Personal use: Not required — the Mini 2 is under 250g
• Commercial use: Required at £10.33/year for any business or professional purpose
• Must be displayed on the drone when applicable

Step-by-Step Registration

1. Go to register-drones.caa.co.uk and set up your account
2. Select "Get a Flyer ID" from the dashboard
3. Take the 20-question theory test — covering UK airspace rules, distance requirements, weather awareness, and data protection responsibilities
4. Score at least 16 out of 20 — results are instant, and you can retake immediately if needed
5. Download your Flyer ID and keep it accessible during every flight
6. For commercial pilots: Also apply for an Operator ID (£10.33/year) and label the drone

Registration takes about 15 to 20 minutes from start to finish. The process is the same whether you fly a brand-new Mini 4 Pro or a second-hand Mini 2.

Where You Can Fly

The Mini 2 operates under Open Category A1 rules as a sub-250g legacy drone. The same rules apply to all drones in this category:

• Maximum altitude: 120 metres (400 feet) above ground level
• Visual line of sight: Maintain direct, unaided visual contact with the drone at all times
• Flight Restriction Zones: Check the CAA Drone Safety Map before every flight. Airports, military bases, prisons, and sensitive infrastructure have protected airspace
• People and buildings: As a legacy drone without C0 marking, maintain 150 metres from residential, recreational, commercial, and industrial areas. Do not fly over uninvolved people
• No obstacle avoidance: The Mini 2 has no side or forward sensors. You must maintain safe distances from obstacles manually at all times

Buying a DJI Mini 2 Second-Hand: What to Check

Since the Mini 2 is discontinued, most purchases in 2026 are second-hand. Here is what to verify before you buy:

• Firmware version: Check that the drone can be updated to the latest firmware through the DJI Fly app. Older firmware versions may have known issues or reduced functionality
• Battery health: DJI batteries degrade over charge cycles. Ask how many charges the batteries have had. Batteries with over 200 cycles may have noticeably reduced flight time
• Physical condition: Inspect propellers, motors, and the gimbal for damage. A crashed drone may fly but could have hidden issues
• DJI account transfer: The previous owner should unlink the drone from their DJI account so you can register it to yours
• Accessories included: Check whether spare batteries, charging hubs, and carrying cases are included. These are becoming harder to find individually

From a regulatory perspective, buying second-hand changes nothing. The registration is personal to the pilot, and the drone itself does not need to be registered separately for personal use.

DJI Mini 2 vs Current Models

If you are choosing between a second-hand Mini 2 and a current model, here is how they compare from a compliance perspective:

• Registration: Identical for all sub-250g DJI Mini drones — Flyer ID required, no Operator ID for personal use
• Safety features: The Mini 2 has no obstacle avoidance, while the Mini 3 has bi-directional, the Mini 3 Pro has tri-directional, and the Mini 4 Pro has omnidirectional sensing
• Flight time: The Mini 2 offers 31 minutes, which is slightly less than newer models
• Camera: 4K/30fps is still capable for recreational use, though the Mini 4 Pro offers significantly more advanced features
• Price: A second-hand Mini 2 typically costs significantly less than a new Mini 4 Pro, making it an accessible entry point

For pure compliance, the CAA treats all these drones identically. The choice between them is about features and budget, not registration complexity.

Common Mistakes

• Assuming a second-hand drone is already registered: The previous owner may have had a Flyer ID, but that does not transfer to you. You must obtain your own Flyer ID before flying
• Skipping the Flyer ID because it is a small drone: A Flyer ID is required for all drone pilots in the UK. The sub-250g category only exempts the Operator ID for personal use
• Not updating firmware: Older firmware may not include the latest geofencing data or safety patches. Always update before flying
• Flying without checking airspace: The CAA Drone Safety Map should be checked before every flight. This takes seconds and prevents potentially serious situations
• Adding heavy accessories: At 249g, even small additions can push the Mini 2 over the 250g threshold, triggering the Operator ID requirement for personal flights
