I have seen a couple. Not sure if they were here or on Facebook. Basically it is a bit of plastic that slips onto the current controller and has some reflective metal. A very basic way to increase range. My searches aren't turning up what I am looking for. More then likely I am not using the correct terms. I have come across the following Parabolic Antenna Reflector Booster fr Phantom 3 Inspire 1 Controller Windsurfer Anything else out there?
