I am having issues with the basic setup of Core - Champion SRS and PBR-26D. I have updated the Champion to V0.9 and chosen P2Bus in RX/TX menu. The PBR's are connected to RX1 and 2 and are linked and green. The settings for the PBR in the receiver menu at the Core are chosen as "P2Bus and 18ms" By determining CH1 to a output on the Champion the servo flutters and is not under positive control.
I guess is a basic error, so any advise will be greatly appreciated.
