3) While holding the vertical stabilizer firm-
ly in place, use a pen and draw a line on each
side of the vertical stabilizer where it meets
the top of the fuselage.

lines you drew.
Remove the covering
When cutting through the covering to re-
move it, cut with only enough pressure to only
cut through the covering itself. Cutting into
the balsa structure may weaken it.
5) Slide the vertical stabilizer back in place.
Using a triangle, check to ensure that the ver-
tical stabilizer is aligned 90º to the horizontal
stabilizer.

6) When you are sure that everything is
aligned correctly, mix up a generous amount
of 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 realign. 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 al-
cohol. Allow the epoxy to fully cure before
proceeding.
