I finally got to test the FPVLR Booster after a continuity check of the soldering of the antennas. In comparison with the stock range (600m) in that location, I got to 1,3 km, so I guess I can say I now have a comfortable 1 km range. So, the booster works indeed, but certainly is far from my expectations. I was hoping for 3 to 5 km somewhere, and not a mere 1 km, which the Disco reaches in no time. What range do you guys get out of the booster ? Phil Flyman.
