Mike,
Here's my pushrod set-up on the Goldberg Extra, two elevator servo's with Central hobbies carbon fiber pushrods, pull-pull setup on the rudder.

Pushrods cross down in the fuse and servo's arms are pointed the same direction, this allows the use of a simple Y harness instead of those dreaded reversing Y's, just build up one servo with blocks to avoid the rods hitting each other.

This happens to be a picture of my Goldberg Sukhoi but it's the same set-up.
