That's a very good video. Looks like some tricky maneuvering with the drone. Being a Pink Floyd fan I like your choice of music for this video, much better than Hardcore Techno music which is what accompanies most other videos.
I know how tricky drone control is so kudos for trying the inside - there is a lot more graff now to when I was there. The best bit of that place (for me) was inside the second story but I suppose it would have been a wind tunnel & hard to control the drone. Not worth writing it off for a fly through of this bit
I used to have a mate who trained folk to fly these, he insisted that I have a go, surprised me how many pieces there are to em, I enjoyed your video, Thanks
