Accomplished final drilling of the elevator control horns. Note
: Look close at the plastic drill bushing the plans are talking about. Feel
free to fabricate this bushing from metal if you can find something that
fits. Good luck! The plastic bushing I fabricated came from the internal
organs of a bic pen, and the final results were perfect. Make sure the elevators
are flush and true with the horizontal before drilling, see picture. After
drilling the pilot hole (whatever drill bits fits snug inside the bushing)
remove the elevators and final drill to 1/4".
