Yes the Aux 1 is in "lin". I did some further checking. I beleive the Aux 1 channel is assigned right knob from the factory. I changed it to "nul" on both sides because if you accidently changed this knob position, 1/2 of your elevator would be off. Is this my problem. Does Aux 1 (or channel 7) have to have a switch assignment to link properly?

Thanks for the imput guys, but the 9Z is considerably different than the 8U or 9C.
