I use the Rcblimpro type setup. But, I make it as inexpensive and bulletproof as possible.
Dubro giant scale aluminum rudder horns - they are adjustable so you can put the pivot right over the hinge line.
Airwild aluminum servo arm - 3 inch eye to eye.
Make sure the width of the attachment points on the rudder horn are the same as the servo arm - then your cables will be parallel. For your plane, the cable holes have already been cut in the fuselage. But, if you didn't know where to exit the cables, all you have to do is measure the width of your servo arm. If the servo arm is 3 inches wide, the cable will exit exactly where the fuselage is 3 inches wide.
For cable, use nylon coated stainless steel fishing leader (Berkely is what I use), about 80 lb test. Buy the metal crimps of the correct size while you're at the fishing store. Loop the cable through the crimp for a better grip and no slip. Squeeze down in the center of the crimp so the ends of the crimp won't fray the cable.
