I was told that the rudder horn supplied witht he first batch of kits was made with too much of an angle so that it could hit the fuse with full throw so I decided to go with a more standard rod through the rudder. I used 2 of the new Central hobbies horns to match the horns on the elevator and rudder with a piece of threaded 3mm rod long enough to work. The rudder is pretty thick back there. A couple of nuts and washers on the 3 mm rod would have done just as well and would be a bit cheaper

I marked the fuse from the rudder servo to where I thought the rudder horn should go. Bright lighting the rudder did not work as it did with the aileron and elevator. Not sure if the paint is thicker or the structure is different but I could not make out the wood block. I marked where it was by feeling where the rudder skins did not compress. The center came out to be about 152mm from the bottom of the rudder which matches the point listed in the the Integral manual. (Valiant manual is not available yet). I used the same method as I did for the aileron. Turns out that I did not hit the center of the block but just got the top of it. About half of my CF tube would be glued to the block. Should not be a problem. I think the center hinge support fooled me into thinking that the block was larger. Like the aileron it is only about 10mm wide. So be careful to find the center. About 147 mm from the rudder bottom should work. I used a longer piece of 3mm rod through the CF tube to make sure that it was glued in proper alignment to the rudder.

In order to figure out where the pull pull cables exit the fuse I drew the fuse top view on my bench from rudder servo to rudder horns. My rudder servo horn is about 50mm wide and the rudder horns came out to be 74mm apart. With straight cables the opening would be about 310mm from the rudder horns and with crossed cables 170mm from the rudder horns. I choose crossed cables. I like to have a guide tube through the fuse and glued in a short piece of 1/8" CF tube after filing in the slot at the right angle. I can't hook up my cables yet as I have to get some. My preferred cable which has never failed me is Berkly Steelon plastic coated wire fishing leader, 30 or 45# test. They sell the right size crimping sleeves as well.
