When i first picked up my PA from the dealer. They showed me how to run and mount the rudder control. The control cable was run around the outside of the seat. Problem is i was getting alot of binding while steering. After going with a friend to a different dealer to pickup his PA. That dealer showed me a different way to run the control.
Instead of running on the outside you run it strait under the seat,in the channel.
I used to clip the control on the front of the seat. Now i clip it to the side as shown.
What this does is give the cables a gradual bend instead of the hard 90 degree bends around the seat. Doing it this way eliminates the rudder binding i was having.
