Received my FPVLR antennas yesterday and had a chance to fly with them all day today. I am a very happy camper with this setup. I was getting about 1600 feet with the stock antenna. I took it out 3100 feet at 80 feet in altitude and not even a flicker in the video. I didn't even have good LOS most of the trip due to trees. I probably won't see how far it can go because I have large mountains all around me and 3500 is about all I can do. Not a world record but I'm happy with the solid signal for what I do.
