21. Cut the 3/4" x 1-1/4" x 15" balsa stick in half, making
two 7-1/2" fin fillets. Tack glue these fillets to the fuse top
and the fin filler block.
****Time to make some dust!****
22. Shape the turtle deck top to the round shape of the
turtle deck, using the cross sections as a reference. Do the
same for the fin fillets and the fin filler block, blending
everything smoothly. Hint: Start your shaping with a razor
plane, then use a course sand paper (around 100 grit), then
gradually work with finer paper until you are using 400 grit
to get a really nice final shape that's cleanly sanded.
23. Final sand the rest of the fuse, being sure to clean up
any rough spots or CA smears that will show through your
covering work. Use balsa filler as necessary to fix any small
nicks or dings that happened "mysteriously" during assembly.
24. Cut the fin fillets and the fin filler block from the fuse.
Separate the fin fillets from the fin filler block.
Mount the Stabilizer and Fin
1. If you have not already done so, make sure the stab
and fin are final sanded to a smooth finish, as it will be a little
more difficult to do so after they are glued to the fuselage.

2. Mount the wing to the fuselage. Center the stab in the
stab slot. Use a string from the center of the firewall to align
the stab the same as was done with the wing.
3. Stand about six to ten feet behind the model and see
if the stab is parallel with the wing. If necessary, sand the
stab base with a thin sanding block until the stab is parallel
with the wing.
4. Epoxy the stab in place, double-checking the
alignment. Wipe any excess epoxy from the stab with a
paper towel and alcohol. Hint: After the epoxy has cured,
you may remove the wing from the fuse and set it aside if
you prefer to make the model easier to handle.
5. Fit the fin in place and check that it is perpendicular to
the stab with a square. If it is not perpendicular, small
adjustments can be made by sanding a taper on the fin post,
