Last evening I went to an area I had not flown before and wanted to get some shots of a lake and this nice tower. I had already flown the P3 around and got some good video. On the second battery I started back toward the tower with the intent of starting low and slowly rising up the tower for a cool shot. The P3 was probably 50' high and 200' away when the FPV went black. Just said no connection. It was hovering so it luckily wasn't in trouble but video was gone. I checked the HD channels and they were all locked with no movement at all. The app was fine, nothing was locked up or anything. So I turned the bird around and started flying back and after about 50' or so video came back on. What happened?? Is that tower a cell tower maybe? I flew by it already once.
