As a taildraggr, there are not pushrods that go through the firewall to the nose wheel steering yoke to keep the rudder pedals in postion. without something, the pedals would fall rearward and no tension would be on the cables. I solved this problem by installing a 1-1/2 diamter pulley on the firewall and made small plates to attach to the rudder pedals where the pushrods would. a short cable is used to connet the two pedals.
