✑ 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 stabi-
lizer mounting area. Apply epoxy to the bot-
tom 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 measure-
ments 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 ep-
oxy to fully cure before proceeding.
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.

✑ 2) Slide the vertical stabilizer into the slot
in the top of the fuselage. The rear edge of
the stabilizer should be flush with the rear
edge of the fuselage and the lower rudder
hinge should engage the precut hinge slot in
the lower fuselage. The bottom edge of the
stabilizer should also be firmly pushed against
the top of the horizontal stabilizer.
✑ 3) While holding the vertical stabilizer
firmly in place, use a pen and draw a line on
each side of the vertical stabilizer where it
meets the top of the fuselage.
✑ 4) Remove the stabilizer. Using a mod-
eling knife, remove the covering from below
the lines you drew. Also remove the covering
from the bottom edge of the stabilizer and the
bottom and top edges of the filler block. Leave
the covering in place on the sides of the filler
block.
