edge contacts the fuselage. Perform the same
technique for aligning the stab as was used for
aligning the wing. This time, the center on the
fuselage is at the front, rather than the rear. Mark
the stab so it can be returned to its aligned location.
3. Mount the wing to the fuselage using the
nylon bolts. Stand back 8 to 10 feet and view the
model from the front and rear. The stab tips should
be equally spaced above the level of the wing. If
not, lightly sand the high side of the stab saddle to
correct the problem. Work slowly and check the
alignment often.
4. Use a felt-tip pen to mark the sides of the
fuselage on the bottom of the stab. Remove the
stab from the fuselage.
5. Use a fresh #11 blade to carefully cut through
the covering 1/16" [1.6mm] inside the lines you
marked on the bottom of the stab that indicate the
fuse sides. Do not cut the wood under the
covering! This will weaken the structure and
may cause the stab to fail in flight. Remove the
covering from the center of the stab within the lines
you cut. Remove a 1/4" [6mm] wide strip of
covering from the top of the stabilizer along the
centerline.
6. Use a liberal coating of 30-minute epoxy to
glue the stab in position. Hold the stab in position
with weights and clamps while the epoxy cures.
Double check alignment with the wing and fuse
while the epoxy cures. Important: Form a thin
epoxy fillet along the fuse sides where the epoxy
squeezes out to create a fuel proof seal between
the stab and fuselage.
