Update
6 months lost, finally re-found!
Just take a look at that sexy wiring on pic 4. Currently still a bench-bound quad. I don't know how to get this FC to do ibus yet.
Still, If I crash this thing I might actually cry. Probably my prettiest build to date. Love the frame.
That is probably my next frame, and what a cool hardware setup you have chosen! It kills me to hear that you haven't gotten it up in the air, here is a great video that should explain everything you need to know to get your FC and Rx talking!
