Dont forget that a final mount for the tube just ahead of the throttle servo. You want it far enough ahead that the bending action doesn't pinch the cable. I use a 1/4 x 3/8 stock and find the spot I want to secure the servo end. I use two of them and place them together and the drill a hole through the joint between the so i can CA one to the fuselage side and then run the cable shieth through them, then CA the other to lock it down. As long as you have both the servo end and the firewall end tight, the cable will provide that right movement following the servo.

I fly four strokes and the cables give me a lot of flexability over a solid wire. The Four strokes require some interesting paths around the tank and still exit the fire wall at the right place to smothly operate the throttle arm. A solid wire usually won't work without binding. With the cable, just make sure both ends of the sheith are positioned right and are locked down. That determines the movement of the cable.
