Hi
I cant find a manual for the XB1-14DRS yet but a common feature of JR DMSS RXs so far is you get PWM or X-Bus output "not" both. If indeed you cant have both with this 14ch Rx when you try to use the gyro with this Rx it will become a 6ch setup and end up with dead PMW outputs and having to fit hubs. If that's the case you would be better off with the RG031BX . I hope JR have resolved this but I would ask first to avoid disappointment.
