I looked over the guide and that is exactly what I am doing except that I am using aux3 instead of aux 2. I disable the nob the same way and and use the mixes the same way. I even tried it the same way with aux2 that the link had and one servo is still moving more than the other. In the stick monitor screen on my 8103 it even tells we that the servos are moving the same distances, but I can clearly see that they are not.
