Thanks JoeAirPort, that helps a lot. Now does the arm on the servo have to be the same width as the attachment points on the rudder?I do know that if the attachment points of the cable which attach to the rudder itself does not fall on the hinge line, you need to offset the attachment point of the cable on the servo end with an angled servo arm, right? Though that wouldn't be the case with this Du-Bro set up.
