After mounting the servos, I had to then run the pull/pull exit locations. This where the laser level again saved the day. We taped/marked the position of the laser from the servo arm, to the location of the control horn looking down on top of the fuse. Then marked with tape with a laser line from the side. Where the two pieces of taped crossed, was where the exit of the pull/pull line would be. Very accurate and simple. Note, the pins in the picture are to keep my ca hinges centered. I also use carbon fiber rod for my control horns (thank you Nat Penton). I drilled an 1/8" hole (carefully) straight through a hardwood dowel hardpoint and ca or epoxy it in place. The nylon eyelets can be ca'd onto the rod later when the linkage and throw is set to my liking. Also note the MK tailwheel....very light. I also drilled some lightening holes in the tailwheel plate as it was very large and thick (1/4", 7 ply).
