25.
To attach your Fin Unit, you will need to apply a bead of
glue along the bottom 2 inches of each fin line as shown in
Figure 25.
Figure 25
26.
Referring to
Figure 26,
slide the Fin Unit onto the bottom
of the body tube so that the lines of glue fit inside the
CORNERS
of the Fin Unit and do not touch the fins. The
bottom of the Fin Unit should be even with the bottom of
the body tube.
(
Thing-a-ma-FACT:
The
Leading Edge
of a fin
is simply that part of a fin that
LEADS
the rest of the fin in flight.
You will notice in the figure that the Leading Edge is the edge that
faces the direction of flight. Likewise, the
Trailing Edge
is the
edge of the fin that
TRAILS
(is behind) the rest of the fin in flight.

Now you must TWIST the fin unit around so that all 3 lines
of glue come into firm contact with the fin unit and the
Launch Lug is now aligned with a corner of the fin unit, as
shown in
Figure 27.
When complete, apply strong glue
fillets to all 3 corners of your Fin Unit as shown in the
bottom of
Figure 27.
(
Thing-a-ma-FACT:
Glue Fillets
are like
beads of glue
. You apply the bead of glue then smooth it out
with the tip of your finger. This will make the joint very strong and
will also make the joint look better when you apply paint.
