If you follow the FB Groups you probably already saw these. I have been doing some testing on some of the popular antenna combos. This is ground based testing and far from scientific. Solo Antenna Study - Google Drive This second study is a little more viable as it was done under a more controlled environment in actual flying conditions. Phase one I aquired a set of base lines using the stock leg antennas. My results are tabulated in a pdf- goo.gl/UV63fj Phase two will be after replacing the leg antennas with the rubber ducks off the controller to repeat the same test sequence to try and determine if there is any appreciable signal gain.
