MINI SPARROWHAWK EP
INSTALLING VERITICAL FIN.
1) Using a modeling knife, remove the
covering from over the precut hinge slot cut
into the lower rear portion of the fuselage.
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 stabi-
lizer 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.

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 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.
