2) Position the elevator horn on the both
side of elevator. The clevis attach- ment holes
should be positioned over the hinge line.
5) Slide the vertical stabilizer back in
place. Using a triangle, check to ensure that
the vertical stabilizer is aligned 90º to the hori-
zontal stabilizer.
6) When you are sure that everything is
aligned correctly, mix up a generous amount of
Flash 30 Minute Epoxy. Apply a thin layer to the
mounting slot in the top of the fuselage and to
the sides and bottom of the vertical stabilizer
mounting area. Apply epoxy to the bottom and
top edges of the filler block and to the lower
hinge also. Set the stabilizer in place and re-
align. Double check all of your measurements
once more before the epoxy cures. Hold the
stabilizer in place with T-pins or masking tape
and remove any excess epoxy using a paper
towel and rubbing alcohol. Allow the epoxy to
fully cure before proceeding.
3) Using a 1.5mm drill bit and the control
horns as a guide, drill the mounting holes
through the elevator halves.

Mount the control horns by inserting the
bolts through the control horn bases and
elevator halves, then into the mounting
backplates. Do not overtighten the nuts or the
backplates may crush the wood.
5) Position the rudder control horn on the
left side of the airplane. Mount the control horn
parallel with the horizontal stabilizer.
6) Install the rudder control horn using the
same method as with the elevator control
horns.
