eBay isn't the only way of selling something.
You do not need to register if you will only fly or use the following types of drone or model aircraft:
toys below 250g or in C0 class
those in C0 class with no camera, whether they are a toy or not
those below 250g with no camera and no class...
Be a bit of a surprise to the original purchaser if they sold it on to someone second hand...or gave it away as an unwanted present...
