Hi Guys ,Wondering if any one can help with setting up my dji air unit to work on my immersion vortex 285 , I have powered the unit successfully by soldering power leads direct to main battery power pads , I just wondered where the UART tx rx pads are to connect the white and grey for OSD functionality so I can get full benefits from OSD , I am using my own EZuhf transmitter and receiver so donít plan to connect yellow and brown and have removed . Any advice would be greatly received .Best regardsAaron
