Remove the covering from the inner hinge area of each elevator as shown. There is a loose balsa filler
piece under the covering
.
Remove it as shown, opening up the elevator joiner slot in both of the
elevators. Locate one control horn and modify it as shown to fit in the left elevator. We used a small
file, a Dremel tool also works well.
Use a generous amount of medium or thick CA glue to install both the joiner and the elevator control
horn into the left elevator as shown.
