I am nearing the end of my S900 build. Here is what I have so far:

-A2 Flight controller
-GH4-Z15 Gimbal
-GH4 Camera/12mm Lens
-Lightbridge 2
-Spektrum DX8 Transmitter
-AR7700 Spektrum PPM Receiver
-iOSD Mark II (Do I even need this with Lightbridge to get telemetry, nobody seems to know...)
-16,000mah 6S Battery

The problem I am having right now is that the instructions for the lightbridge 2 told me to plug the D-BUS cable in to the X2 port on the A2 flight controller. Then tonight, my Spektrum AR7700 PPM Receiver shows up, and I look at the instructions for the A2 Flight controller, and it tells me to plug to cable into the.... You guessed it, X2 port. What do I do now? I just want any progress possible at this point....
