I have a new Pioneer that has (2) SPM4651Ts connected via SRXL2. I am using a JR12X transmitter. LIFE airborne battery. I bound both receivers to the 12X...no problems. Problem is, only channels 1-7 will drive a servo. Channels 8-12 do not respond to transmitter commands. I have verified proper transmitter operation with another Spektrum 12ch receiver. I have swapped the receiver and battery inputs with no change in operation. The Pioneer had version 3 installed when I got it. I updated the firmware to version 1. Is what I am trying to do going to work? Do I have a configuration problem?
