Ok, so here are a few pics. Sorry for the quality, my camera is having problems.
Notice the pull/pull is under the servos. You could run your rudder pushrod in this area. Also notice I used micro servos. I did this because I had a pair. Standard servos would have worked. One thing you can't see is after I cut the opening for the servos. I joined the two sides of the fuse with a 1/4" square balsa stick right behind the servos. Even though this plane has ply fuse sides, I wanted to be sure there was no flex in this area. I fly my stuff HARD. So a litle strength pays off in the long run.
