Hey all,        Anyone already wire up a DJI Air unit to the Mamba f405 mk2?  I am using crossfire nano and want to get beta flight OSD.  I could just hook up the Air unit to the 4s lipo with a capacitor.  I want voltage and flight time on the osd, but RSSI would also be great.  Any suggestions would be very helpful in my build soon to begin using the Mamba stack/40amp with emax motors.   Stu

Same here ,no osd. Coming  from a xm+ I only  have three wires. I need a fourth  ,but were  does  it connect?
