I would suggest also you run two 2-56 rods off the pushrod dowel so the pushrod goes to both elevator halves rather than just one side. If you do it like the instrauctions and plan on doing serious 3D like a wall or waterfall, the side without the pushrod will always lag behind. I put the servo in the tail for the rudder because it needed a lot of tail weight.............and it was easier than the pull/pull.
