3. Measure and mark an accurate centerline on the top
of the horizontal stabilizer. Make sure to mark the
centerline on the trailing edge also.
❏
4. Insert the stabilizer into the stabilizer slot so it is
centered in the fuselage (dimension A should be equal).
Place the wing onto the fuselage and secure it in place with
the wing hold-down bolts. View the plane from the rear and
at a distance of a few feet. The stabilizer should be parallel
to the wing (dimension B should be equal). If not, sand the
stabilizer mounting base slightly to achieve the proper
position of the stabilizer.
❏
5. Attach a piece of string with a T-pin to the top center
of the firewall. The string should be long enough to reach to
the horizontal stabilizer. Align the stabilizer using the same
method that was used for aligning the wing.
❏
6. With the stabilizer properly aligned, use a felt-tip pen
to trace a line around the tail of the airplane on the top and
bottom of the horizontal stabilizer.
❏
7. Remove the stabilizer and draw two additional lines, top
and bottom, 1/16" [1.6mm] inside the lines drawn in the
previous step. Using a new #11 knife blade, carefully cut
through the covering along the inside lines and remove the
covering from the center. Do not cut the wood under the
covering! This would seriously weaken the stabilizer and
could easily cause the stabilizer to break in flight. Be very
careful when you make this cut. If the covering is not removed
from the stabilizer, a proper bond will not be achieved.
❏
8. Mix 30-minute epoxy and spread some inside the
horizontal stabilizer mount on the fuselage. Spread more
epoxy onto the top and bottom of the stabilizer where the
covering was removed. Inser t the stabilizer into the
fuselage from the rear and adjust the alignment using the
guide lines that were drawn onto the stabilizer in step 6.
Wipe off any epoxy that squeezes out using a paper towel
dampened with rubbing alcohol. Recheck the alignment
frequently while the epoxy cures.
