The steering arm has a brass rod that the white nylon piece slides on. The clevis from the servo steering rod pivots on the white nylon piece while it is sliding on the brass rod. So, when the gear retracts, the pivot point on the retract brass rod steering arm actually changes and keeps things from twisting or binding. If this doesn't help, I will plug the problem into my Marconium Wave Extrapulator and see what comes out.
