Went out yesterday Evening and set the bird down and decided to try see how far I could take it straight out this is the video from it, just a stock Phantom 3 Pro with a windsurfer Antenna on.....went out to 9545 feet one way, maybe could have gone a bit farther if i would have taken it up a bit higher but I was already up around 800 feet and started to lose video signal so chickened out and headed for home, still impressed me thou with that distance...
