Install
the
Vertical
Fin
Step
1:
Test
fit
the
vertical
fin
in
the
slot
in
the
top
of
the
fuselage.
Sand
the
edges
of
the
slot
if
necessary
to
obtain
a
snug
fit.
Draw
a
line
around
the
vertical
fin
where
it
meets
the
fuselage.
Cut
the
covering
1/16”
[1.6mm]
inside
the
lines
you
drew
on
the
vertical
fin
and
the
top
of
the
fuselage.
Remove
the
covering.
Step
2:
Mix
some
30
‐
minute
epoxy
and
apply
it
to
the
top
of
the
horizontal
stabilizer
through
the
slot
and
on
the
sides
of
the
slot.
Apply
more
epoxy
to
the
vertical
fin
where
the
covering
was
removed.
Insert
the
vertical
fin
into
the
fuselage
and
adjust
the
alignment.
Check
for
a
90
degree
angle
between
the
vertical
fin
and
horizontal
stabilizer
when
viewed
from
the
rear.
Use
masking
tape
to
hold
the
vertical
fin
in
this
position.
Recheck
the
alignment
frequently
while
the
epoxy
cures.
