Here are the key dimensions. This puts the cable 4.5 inches above the lower stations or longerons. The red lines are just drafting lines. They showed 3 different positions of the cable mount with stick center, forward, rearward. There is a maximum 0.020" difference in cable length between the forward pulley an the rear cable guide with the stick moving trough the three positions. The cable mount is 3 inches above the stick pivot point. The pivot point is about 0.080" below center line of the torque tube. That was initially to allow maximum space for the cable when I drew it running through the tube.
I made another drawing with the cable passing through the tube, the pivot was mounted just under the tube. It lowered the cable by just over 1/2 inch but complicated a few other things. So I think the version shown is what I will go with... unless someone tells me that 4.5 inches above the longeron is too much.
