Section 5: Installing the Horizontal
and Vertical Stabilizer
Step 13. Mix up approximately 1/2 ounce (minimum) of
30-minute epoxy to attach the horizontal stabilizer to the fuse-
lage. Slide the horizontal stabilizer back into the fuselage. Epoxy
will have to be worked into the fuselage opening by sliding the
horizontal stabilizer back and forth (approximately 1/8"-1/4") and
applying epoxy to the top and bottom surfaces. Use an epoxy
brush to apply the epoxy. Some can be inserted through the top
vertical stabilizer slot, but use care not to overdo, as the vertical
stabilizer will have to be installed also.
Step 14. 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 junc-
tion 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 15. Mix up 1/2 ounce of 30-minute epoxy and apply to
the vertical stabilizer where the fuselage contacts it. Also, apply
epoxy to the base of the vertical stabilizer where it mounts to the
fuselage and horizontal stabilizer. Insert the vertical stabilizer into
the fuselage and wipe away any excess epoxy with a paper towel
and rubbing alcohol.
Step 16. Check the alignment of the vertical stabilizer to the
horizontal stabilizer and wing by sighting from the rear of the air-
craft. Use masking tape to hold the vertical stabilizer in place
while the epoxy cures. Allow the epoxy to cure completely.

Step 17. The right and left wing panels may be removed at this
time to ease the construction process.
