I'm using DRL on my spektrum via wireless dongle and on my turnigy evolution via micro usb both being very easy to set up
Not sure with the taranis, but the spektrum dx6e has no usb port so the dongle acts like a receiver that plugs into a usb port on your puterVery cool idea with the wireless dongle.., what kind?, and would a taranis be able to use one?, sounds like you have a sweet setup
