This is by far the best pull-pull and elevator setup I've seen. I learn this setup from a Free Style 3D from Global I'd recently gotten. From the diagram, as you can see, the rudder servo is right on the center line of the plane. Also, the travel of the elevator servo horn is on the center line of the plane. The rudder cable cannot hit either the throttle or/and elevator servo because it rises above them via the rising blocks.

Since I ran the entenna inside the plane, I did not use the metalic pull-pull cable that came with the plane. Instead, I used the Sulivan kevlar cable setup that I bought from Tower. It's about $10. Part # LXFV28.

$10 is a bit expensive for one setup. For my future planes, I would just buy a spool of kevlar ($2.50 for 100') and 2-56 loop-hooks from Home Depot and build similar system.
