13. Once the stabilizer has been aligned, use a felt-tipped
pen to transfer the outline of the fuselage onto the top and
bottom of the stabilizer.

14. Remove the stabilizer from the fuselage. Use a
hobby knife and a new #11 blade to trim the covering 1/16-
inch (1.5mm) inside the lines drawn in the previous step.
Remove the covering, exposing the wood at the center of
the stabilizer. Use a paper towel and denatured alcohol to
remove the pen lines from the stabilizer and fuselage.

Make sure to use a new #11 blade and
use light pressure to trim only the covering.
Avoid cutting into the underlying wood, which
could weaken the structure of your model.

15. Mix 1/2 ounce (15mL) of 30-minute epoxy. Apply
epoxy to the exposed wood on both the top and bottom of
the stabilizer. Slide the stabilizer into position in the fuselage.
Use a paper towel and isopropyl alcohol to remove any
excess epoxy before it cures. Recheck the alignment of the
stabilizer while the epoxy is curing to make sure it doesn't
change position in the fuselage. Allow the epoxy to cure
before resuming building your model.

amount of medium CA to glue the black-covered balsa block
in position at the rear of the fuselage.

the fin into position on the fuselage. Use a felt-tipped pen to
trace the outline of the fuselage on both sides of the fin.

and a new #11 blade to trim the covering 1/16 inch (1.5mm)
below the lines drawn in the previous step. Remove the
covering, exposing the wood at the bottom of the fin. Use a
paper towel and denatured alcohol to remove the pen lines
from the fin and fuselage.
