1. Locate the items for this section of the manual.
2. Use a hobby knife with a #11 blade to remove the
covering at the rear of the fuselage to expose the slot for the fin.
3. Remove the rudder and hinges from the fin. Slide the
fin into position on the fuselage. Use a straight edge to align
the fin with the rear of the fuselage. Use a felt-tipped pen to
trace the outline of the fuselage on both sides of the fin.
4. Remove the fin from the fuselage. Use a hobby knife
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.
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.
5. Mix 1/2 ounce (15mL) of 30-minute epoxy. Apply
epoxy to the exposed wood on the bottom of the fin and
into the slot in the fuselage. Place the fin into position and
remove any excess epoxy with a paper towel and rubbing
alcohol. Use a straight edge to align the trailing edge of the
fin with the fuselage as shown in step 3. Use care not to use
too much epoxy, as it could accidentally get into the area of
the elevator joiner wire.
