The camera means it needs registered, but it’s not very onerous and there are no competency requirements. The new rules actually give you more freedom in terms of where you can fly, so it’s a good deal IMO.

You only need insurance for commercial operations.

I looked over at some Austrian and German pages wrt new EU rules and they all mention that Mini 2 has to be insured (25-50EUR/year).

Well, member states are free to go beyond the EU rules and add their own local ones, so it might be true in those countries. I don’t believe you need insurance for hobby activities in the UK, though I’m not an expert and open to being corrected.
