Hi @Mikemogs. Re the registration.
Based on what we know now - Everyone who owns a drone between 250gm and 7kg will need to register as a drone operator and you will then be required to have you own registration code visibly displayed on any drone you own when it is being flown. Cost not know but I’m guessing between £5 and £10m. Important to note that it is the person not the the drones that is registered
Everyone who flies a drone between 250gm and 7kg will need to take the online test. So if you let someone else fly your spark, they will have to pass this test first the. And this includes on private land and even in your own back garden. No suggestion of a cost for this as yet.
Now this could still change, depending on ongoing consultation, but not likely to be much different.
Hope that makes sense?
