I'm pretty new to the drone game and purchased a phantom 3 4K. I had high hopes of using it in my roofing business to inspect tall buildings. So far the recorded video is incredible but the connection from the phantom to the controller is terrible. More often then not I get about 300 ft and the video starts to garble, not long after that I get warnings about connectivity. I've seen people flying in all sorts of environments with no problems. Am I doing something wrong? Are there settings to check? Help please!
