You may have read, or seen on the news The Government in July 2017, stated in the future Drones over 350 grams, need to be registered in the United Kingdom, by Pilots aged over 18 years of age, and some sort of training course and exam would be required for Pilots to pass, to fly drones as a Hobby!
Drones – are you flying yours safely? (and legally?)
Parliament issued an update in November 2017
DJI Drone World leader changed their Smartphone Application today, and before you could fly you needed to Pass their DJI Knowledge Test, which had 8 questions about flying drones in the UK, you only get four attempts to take the test, and I assume then if you do not pass, you cannot fly your drone!
