@Sir Alien
>>"ANY" model aircraft whether fitted with a camera or not, is not allowed to fly within a set radius of an airport or critical location (e.g. large packed stadium). This is just one example.
Actually the CAA UK regulations only restrict A, C, D and E airspace for drones (and other craft) over 7Kg or having a camera (although technically any surveillance, which could mean other telemetry or even audio).
In fact, If it's under 7Kg and doesn't have any kind of surveillance then the only rules are you must be able to see it (direct line), you're not allowed to drop anything from it, and (the kicker, which might get you) "be reasonably satisfied the flight can be safely made".
