Using a modeling knife, carefully remove the film
covering from the tail slots at the rear of the fuselage.
Make sure that you do not remove any wood from the
slots as this will affect the alignment of the tail.

4)
Check the fit of the horizontal stabilizer in its
slot. Make sure the horizontal stabilizer is square and
centered to the fuselage by taking measurements, but
don’t glue anything yet.
Check to mark sure the wing and stabilizer are
paralell. If they are not, lightly sand the opening
in the fuselage for the stabilizer until the stabilizer
is paralell to the wing, but don’t glue anything yet.

With the horizontal stabilizer correctly aligned,
mark the shape of the fuselage on the top and the
bottom of the tail plane using a water soluble / non
permanent felt-tip pen.
6)
Remove the stabilizer. Using a modeling knife
and ruler
CAREFULLY
cut 1mm
inside
the marked
lines. Remove the covering from the top and the
bottom of the tail plane.
Make sure you only cut with enough pressure to only
cut through the film and not the wood. Cutting into
the balsa structure may weaken it. This could lead to
possible failure during flight.
