Temporarily install the control horn, cut out around the base like we did for the aileron and elevator
control horns. Once the covering is removed below the base plate, leave the horn in place and attach
the other ball link. Next, push the control horn in the slot in one direction until you can see the holes
in the center. Apply glue to the area and push the arm back to center. Make sure it is perfectly
centered using a ruler. The pics below are from the 104” slick but accurately illustrate this process.
