STEP 3: MOUNTING THE HORIZONTAL STABILIZER
❑ Remove the stabilizer from the fuselage.
❑ Using a modeling knife, carefully cut away and remove the covering
material from between the lines you drew on the bottom of the stabilizer.

✦ When cutting through the covering to remove it, cut with only enough pressure to cut through only the covering
itself. Cutting down into the balsa structure could weaken the stabilizer and cause it to fail during flight.
❑ Mix and apply a generous amount of 5 minute epoxy to the gluing surfaces of the stabilizer and to the top of the stabilizer
mounting platform.
❑ Set the stabilizer back into place and realign it, double-checking all of your measurements once more before the epoxy sets up.
Quickly remove the excess epoxy and use T-Pins to hold the stabilizer in place, until the epoxy has fully cured.
STEP 4: ALIGNING AND MOUNTING THE VERTICAL STABILIZER
❑ Remove the rudder from the vertical stabilizer and set it aside for now. Again, you can throw away the temporary pieces in the
hinge slots.
❑ Test-fit the vertical stabilizer to the top of the horizontal stabilizer
and fuselage, making sure that the mounting tab in the vertical stabilizer
fits into the mounting slot in the horizontal stabilizer. When aligned
properly, the trailing edge of the vertical stabilizer should be centered
over the centerline you drew previously on top of the horizontal stabilizer,
and the front of the vertical stabilizer should be centered between
the fuselage sides. The trailing edge of the vertical stabilizer should be
even with the trailing edge of the horizontal stabilizer, too.
❑ When satisfied with the alignment, hold the vertical stabilizer in place, using a couple of T-Pins.
❑ Using a pencil, draw an outline of the base of the vertical stabilizer onto the top of the horizontal stabilizer and the fuselage.
❑ Remove the vertical stabilizer and use a modeling knife to carefully cut away and remove the covering material from inside the
outline you drew. Cut away and remove the covering material from the base of the vertical stabilizer, too.
❑ Carefully glue the vertical stabilizer into place, using a generous
amount of 5 minute epoxy. Remove any excess epoxy, using a paper
towel and rubbing alcohol, and hold the vertical stabilizer firmly in place
and aligned, until the epoxy sets up.

✦ While the epoxy is drying, use a builder's triangle to
ensure that the vertical stabilizer is perpendicular to the horizontal
stabilizer.
