This really works!
I have the Phantom 2 Vision Plus ver. 3.0. I have made no modifications to my Phantom. I would loose my FPV signal between 250 and 350 feet using the FPV setting of 640 X 480 at 15 FPS. I lowered the FPV preview setting to 320 at 15 FPS and then I could go a hundred feet more, frustrating. I Downloaded FPV Booster Vision + app and I have made two flights using the FPV booster. Both flights were 1,000 feet away at a height of 300 feet. First flight was using the FPV preview settings at the lowest (320 @ 15 FPS), the second flight used FPV preview settings at 640 X 480 at 15 FPS. Now I can fly farther with a better preview thanks to this app. Each flight showed no signs of glitches in the FPV signal. Its easy to use, there was no configuration, it just works.
