Well I think I figured it out. I moved both the RX cables from P2Bus to Fast track data. I used a separate lead from P2Bus in 1 receiver to the telemetry port in the champion. This was done just like Richard said for the older Royals in compatibility mode on the PowerBox forums. I changed the system from P2Bus to S.Bus and matched the Framerate for both receivers in the CORE to 18ms and 18ms in the champion SRS. And boom, everything works excellent right now! My champion is 3+ years old way before the core came out and that's why it wasn't working with P2Bus. My next Champion was purchased about 6 months ago so that should work with P2Bus.
