All right, so elevator and rudder/tailwheel are done, here's how to add pull/pull, if you were building it in, you'd offset the elevator tubes to the opposite side of the throttle input, but since I built it per plans and changed my mind, I had to set the rudder servo behind and below the elevator and throttle servo tray. The pull/pull is the sullivan kevlar strand type, the servos are for setup, only, I plan on replacing them with the hitec 475's coming sometime this week. Throttle will be a standard type 422 hitec or so. The trick to pull/pull is setup one side and match the other cable as best you can, don't worry about putting a ton of tension on the cables. I've seen guy's set these up with soo much tensionyou could tune a panio with them, unfortunatly, it just invites failure, especially in the turnaround in the threaded adapter. Remove enough slack to take away the play, but no more, remember, when the plane goes from the cool house workshop to the field, the airframe is going to grow as it gets warmer and more humid at the field. Plus, you'll only wear out the bearings in the servo by doing that as well. I simply cut a small piece of brass tubing, about 1 size smaller thanbrass tubing provided in tank systems, CA the strands tight, trim it flush, slip a brass tube on, the 2-56 end piece by dubro (PN-201), loop it through the brass tube and then do another loop back through the tube for security. Add a drop of ca in the tube and let it sit for a few seconds to soak in, now crimp it with a pair of electrical crimpers, I use a pair that are designed for ear tabed type terminals, the kind you find on servo ends and push pin connectors. There, your done, you can also add heat shrink over the brass and loop and make it look more "finished", and add a drop of CA inside to lock it all together, but the CA will cause a hard point and fail eventually down the road on the kevlar, but for stranded steel cable it won't. So it's still feasible for you to do pull/pull, it's all about 1 1/2 hour's worth of work from tubes installed to setting it all up. It takes almost no enery away from the servo and is very persice in movement, you can actually see each step in trim on the servo. I mounted the tailwheel, I installed a blindnut on a plate for the front screw, the rear is just a tapered head wood screw, that one see's almost no load, just the front screw. I also shortened the aluminum dome nut and threaded shaft, I ran into the same issue on my skybolt where the aluminum nut was hitting the rudder fin from initial sag of the bracket. The elevator linkage was going to be bound with copper strand and soldered but I decided to use the wheel collars for the fact that in the future I can remove the push-rods to not only cover the plane but do repairs on the system, it does have drag of the rods but no more than a ounce or two, basically the bow of the rods in the sleeves. The servo doesn't even notice the slight drag. Now I have to setup the engine, and bore the hole for the throttle linkage and set the throttle up, along with the fueler and switch assembly. Basically about another hours worth of work, if I don't get distracted by the GF or the cats?!
