Drones under 250 g

Below 250 g, the rules are lighter in many countries. In the United States, a drone under 250 g flown for recreation needs no FAA registration and no Remote ID, but one flown under Part 107 must be registered. In the EU, a drone under 250 g flies in subcategory A1 of the open category, and its pilot must still register as an operator if it carries a camera and is not a toy. In the UK, a drone from 100 g to under 250 g needs a Flyer ID, and an Operator ID too if it has a camera.
