INSTALLING VERTICAL FIN.
1) Using a modeling knife, remove the cov-
ering 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 sta-
bilizer should also be firmly pushed against
the top of th horizontal stabilizer.
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.

4) Remove the stabilizer. Using a modeling
knife, remove the covering from below the
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.
