Thanks,
I'm sure that is the case, I'm just wondering why it isn't? I haven't used SRXL before but it is my understanding that is is designed to communicate data for all channels in the receiver. I have 4 Cortex Pros but all of my previous installs used the supplied cable and stabilized 2 ailerons, 2 elevators and a rudder.
Maybe someone with more Spektrum experience will chime in. Until then I will set it up using the supplied cable and stabilize just the bottom 2 ailerons.
