Pretty plane!
if you want to run both rxs through the CP you will have to stay dual path. Default is essentially single path and is in the same menu. The cp can’t do a cloned rx through it.
Ive not messed a cb400. My understanding is that you can plug three rxs into it set to ex bus.
Viper, where are you? The R3s are probably fine in most areas. The tough areas (vegas, Mesa az, la) have taken to REx12s for the 2.4s
see the attachment for how to clone should you chose to do so
