Here ya go.

The Nelson rudder bellcrank is mounted on a home-made platform. The elevator pushrod runs right over the top; you have all sorts of room to do it like you want.

If you go with a single split elevator pushrod, it is extremely important that it be centered, or else yoi will get differential throw on the elevators and the plane will be nearly impossible to trim properly. I still can't believe Horizon tells you to offset the servo and pushrod...

Keep in mind that it is EXTREMELY important, when doing a closed-loop (push-pull, pull-pull, whatever) system, that the distance between attachment points at the servo is exactly the same as between the two rudder horn attachment points. IOW, the linkage should describe a parallelogram. Failure to do this will result in assymetrical response, cable slack, the common cold, dandruff, etc.

Have fun. This is a great model.
