I have this set-up from fpvlr.com. I added the voltage monitor myself. As you know when you upgrade with these kits you disable the factory antennas on the controller. I don't always go for long flights so I was wondering that instead of mounting the bulky long range kit each time I fly could I not just buy another set of 2.4 GHZ antennas that would screw into the same antenna ports as the long range upgrade uses. I was thinking these from the same company.
