I am a total newbie and just purchased DJI Mini 2 (249G) Was just testing in field behind garden and neighbour claiming I must register drone first and take a test but I thought I didnt have to do that with under 250g I have booked basic training but was really just messing with drone to get a feel for it. I know there must be certain rules and regulations but that seems to be a minefield as well
The neighbour is a qualified Model airplane user by the way
Yes you must register but the test is optional although its easy and a good learning experience. The 250g is moot in the UK as it has a camera fitted and its not sold as a toy. You must also label the drone. https://register-drones.caa.co.uk
