Most of my FC and RX plug in to each other. This new FC, Mamba 4in1 esc/fc, the RX is wired into the FC. OK. Red is pos. and Blk is neg. The grey wire on my spektrum FPV racing serial dual antenna receiver, where do I solder this wire too...PPM, sbus or ibus? I'm thinking PPM since my set up is Spektrum.
