I think the stiffness is coming from my Z bends. It seems like the middle of the "Z", where the control arm sits isn't tall enough for the arm. I'm using Z bend pliers (hobbico), not sure what to do where. Maybe the push rods are too thick? Again, I have to enlarge the hole to get them to fit. Thats more the stiffness I was talking about. It never actually touches the wing. I'll post some pictures of all ths later.
