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

6. 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.
Epoxy glue.
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.
