q
With the wing mounted to the fuselage, use a ruler to measure the distance
between the tips of the stabilizer and the tips of the wing. Pivot the front of
the stabilizer until both of these measurements are equal.
+
When both of these measurements are equal, you're assured that the
stabilizer is square to the wing.
q
When you're satisfied that the stabilizer is square to the wing, use a T-Pin
to hold the front of the stabilizer firmly in place and aligned.
q
Look from the front of the airplane at both the wing and the stabilizer.
When aligned properly, the stabilizer should be parallel to the wing. If the
stabilizer is not parallel to the wing, you'll need to remove the stabilizer and
sand down the higher side of the stabilizer mounting platform until you're
satisfied with the alignment.

q
Once you're satisfied with the alignment, draw a line on each side of the
bottom of the stabilizer where it meets the fuselage.
WARNING
When cutting through the covering to remove it in the next procedure, 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.
q
Remove the stabilizer from the fuselage, then carefully cut away the
covering material from inside the lines you drew.
PRO TIP
Use a heat-sealing iron to adhere the covering material down
where you cut it. This will prevent it from loosening up and wrinkling.
q
Apply a generous amount of 30 minute epoxy to the gluing surfaces on both the stabilizer and the stabilizer mounting platform.
q
Set the stabilizer into place and realign it, double-checking all of your measurements once more before the epoxy sets up. Quickly
remove any excess epoxy and use T-Pins to hold the stabilizer in place and aligned until the epoxy has fully cured.
q
After the epoxy has fully cured, look closely at the glue joint. If there are any gaps between the stabilizer and the fuselage, fill
them using 30 minute epoxy for added strength.
