There is a type of linkage made with 2-56 metal rods inside plastic tubes. You can buy a set of these and simply replace the inner nylon rod with the metal one. Unless there's a really tight curve on the existing rod, it will work.

My Avistar has that kind of setup with the metal rods inside of the tubes, seems to work. There aren't any significant bends in my 4* but I hope there is enough clearance in the outer tube for the metal pushrods to move freely. I guess I will just have to try and see. Thanks for your help again... One question about the incidence issue. From what I am understanding from what everyone said, the affect on my plane, say if I would shim the leading edge of the wing down, this should make the plane's nose want to point down. Maybe possibly reducing the ballooning, that is if it isn't because of my ailerons?
