  Check to mark sure the wing and stabi-
lizer are paralell. If they are not, lightly sand
the opening in the fuselage for the stabilizer
until the stabilizer is paralell to the wing.

5.  When you are sure that everything is

aligned correctly, mix up a generous amount
of 30 minute epoxy. Apply a thin layer to the
top and bottom of the stabilizer mounting area
and to the stabilizer mounting platform sides
in the fuselage. Slide the stabilizer in place and
re-align. Double check all of your measure-
ments one more time before the epoxy cures.
Remove any excess epoxy using a paper
towel and rubbing alcohol and hold the stabi-
lizer in place with T-pins or masking tape.

Remove covering

6.  After the  epoxy  has  fully  cured,  re-

move

the masking tape or T-pins  used  to  hold the
stabilizer in place  and  carefully  inspect the
glue  joints.  Use  more  epoxy  to  fill  in any
gaps  that   were  not   filled  previously  and
clean up the excess using a paper towel and
rubbing alcohol.

4.  Remove the stabilizer. Using the lines

you just drew as a guide, carefully remove the
covering from between them using a modeling
knife.

   When cutting through the covering to
remove it, cut with only enough pressure
to only cut through the covering it’s self.
Cutting into the balsa structure may
weaken it. This could lead to possible fail-
ure during flight
