Unfortunately with Gatwick, and London, this has been the state of things. Best bet is trying a few local hobby clubs and finding where they usually fly, as most RC plane fields allow drones.
RC flying and drone work just are not the same thing, at least not for me. The drone is just a tool I use for better photography and video, it allows for perspectives and shots that can’t be done from the ground. The flying part is a means to an end. So, in my case, restrictions to an RC Park and the like are not an option.
In fact, given the difficulty of flying in places that are worth photographing has made using the drone nearly pointless. At least in so far as California, Arizona and Nevada are concerned, most of the natural scenery a drone can really exploit for some incredible video is now off limits.
Even extremely remote areas, surprisingly have adopted restrictions. I did a shoot around Pyramid Lake north east of Reno last year. It’s a truly remarkable area, with some incredible, if desolate, scenery. On a return trip this year, I was told by a local authority if I was caught with a drone it would be confiscated. He didn’t say I would be fined, he was very clear, they would take my equipment. The legality of this aside, it was clear I wouldn’t be doing a sequel shoot in the area.
Just to be blunt, either people interested in these tools and/or an industry group starts pushing back, or we will simply no longer be able to use these tools in any meaningful way. That’s just the way it is.
