Section 6: Installing the Tail (Vertical and Horizontal Stabilizer)
Step 12. When you're satisfied with the alignment, carefully
mark the position of the vertical stabilizer where it meets the
fuselage/horizontal stabilizer with a pencil. The pencil should
make a light indentation in the covering.
Step 13. Remove the horizontal and vertical stabilizers from
the fuselage. Using a sharp hobby knife and a straight edge,
carefully cut the covering at approximately 1/16" inside the lines
you drew, on both sides of the horizontal and vertical stabilizer.
Be sure to remove covering at bottom of vertical stabilizer so
epoxy will adhere to it.
Caution: Do not cut into the wood. This will weaken
the structure.
Step 14. Mix approximately 1/2 ounce of 30-minute epoxy to
attach the horizontal stabilizer to the fuselage. Mount the
horizontal stabilizer into the fuselage.

Step 15. Check the alignment of the horizontal stabilizer by
referring to the marks made previously, and measuring the wing
to horizontal stabilizer as done in Step 5 and Step 6. Clean
excess epoxy away from the horizontal stabilizer/fuselage
junction with rubbing alcohol and a paper towel. Use masking
tape to hold the horizontal stabilizer in place while epoxying the
vertical stabilizer in place in the next step.
Step 16. Mix 1/2 ounce of 30-minute epoxy and apply in the
fuselage cavity where the vertical fin will be installed. Apply
epoxy to both sides of the vertical stabilizer, where the covering
has been removed, and to its base. Insert the fin into the fuselage
and wipe away excess with rubbing alcohol and a paper towel.
Step 17. Check the alignment of the horizontal stabilizer to the
vertical stabilizer and wing by sighting from the rear of the
aircraft. Use masking tape to hold the components in proper
alignment while the epoxy cures.

Step 18. After the epoxy has cured, the wing may be removed
from the to ease the construction process in the following steps.
