cable exit...
Here is a shot showing the notch and the recessed outer nyrod before the yellow inner nyrod is installed and sanded flush to the fuse. Look at #48 for the final tiny opening for the cable exit, only the size of the inside diameter of the yellow nyrod.
And, while you are here, note the ply insert on the fuse to support the stab mount fitting and the dowel inserted and tapped in the stab tube.
I like to build customers planes to last a long, long time.
Remember to cross the pull-pull cables or you will never make this work without binding.
Good luck... Ron
