I've had a Phantom 2 for a while now and just sold it and ordered a Phantom 3 pro. I've had this idea about using it for commercial use like estate agent photos etc. is there anyone else doing this and how do you go about it legally. As I understand it you need CAA approval for any commercial use. To get approval you need to do a flight course to say your a safe pilot etc and I'm guessing you need insurance. If I'm right anyone know how much it costs and what's involved and where you can get trained, approved etc? I'm in the Midlands.
