Forgive me if I missed it, but I'm new here and couldn't find a post on this. I went flying with my buddy on Sunday. He's flying a Phantom 2+ and I'm flying my I1. I'd get about 300' up and about 400' away and get "weak signal" warnings on my app and the picture would flicker or drop out. It got especially bad if I stood anywhere near my buddy to see what he was seeing on his screen. His Phantom never gave him any problems at any distance or when I would stand near him. Ideas?
