The included linkages where a bit short for the rudder so I ended up again using hanger 9 titanium quick links. these worked great. You MUST use both sides of the linkage. DO not just use one side because the way the hinges are you will have play and possible flutter. After installing the both sides the rudder will be nice and tight. It is a challenge to get right but when done you will have a flutter free linkage that is hidden and scale.
