The throttle servo installation. I'll probably add a 1/4" square stick between the rails on top of the "wall" in the forground.

I decided to use a Nyrod for this. The distance between the firewall and the throttle arm is much too long for a cable. The servo sits higher than the throttle arm, so there is a curve in the rod - unavoidable - so a wire pushrod would not work well.

Is there a better/lighter way to do the throttle linkage?
