If exposed to direct sunlight and/or heat, wrinkels can appear. Storing the
model in a cool place will let the wrinkles disappear. Otherwise, remove
wrinkles in covering film with a hair dryer, starting with
low temperature. You can fix the corners by using a hot iron.
Bei Sonneneinstrahlung und/oder Wärme kann die Folie erschlaffen bzw. Falten
entstehen. Verwenden Sie ein Warumluftgebläse (Haartrockner) um evtl. Falten aus der Folie
zu bekommen. Die Kanten können Sie mit einem Bügeleisen behandeln. Nicht zuviel Hitze anwenden !

Remove the horizontal stabilizer from the fuselage.
Using the sharp hobby knife, carefully cut away the
covering inside the lines which were marked above.
The elevator hinges are pre-glue into the
elevator halves. Working with one elevator half
for now, apply a thin layer of petroleum jelly to
only the pivot point of the two hinges.
Without using glue yet, push the elevator half
and its hinges into the hinge slots in the trailing
edge of the horizontal stabilizer. There should
be a minimal hinge gap and the end of the
elevator half should not rub against the
horizontal stabilizer.
When satisfied with the fit and alignment, hinge
the elevator half to the horizontal stabilizer,
using thick CA glue. Make sure to apply a thin
layer of CA glue to the top and bottom of both
hinges. Repeat the previous procedures to
hinge the second elevator half to the other side
of the horizontal stabilizer.
Pull the horizontal stabilizer through the other side
of the fuselage and repeat the previous procedures
to glue the second torque rod wire into the horizontal
stabilizer.
Realign the horizontal stabilizer, then glue the
horizontal stabilizer into the fuselage, using a
generous amount of thin CA. Apply thin CA to each
of the four joints and use a generous amount to
ensure to strong bond.

NOTE: You may need to open up the slots of the
horizontal stabilizer so that the vertical stabilizer
is not too difficult to push in.
Cut away only

of the vertical stabilizer. When you are satisfied with the
alignment, use a pencil to trace around the right and left
of the stabilizer where it meets the fuselage.
Cut away only the covering
on the left and right side.
Remove the vertical stabilizer from the fuselage.
Using the sharp hobby knife, carefully cut away the
covering inside the lines which were marked above.
Realign the vertical stabilizer , ensure that the vertical stabilizer is perpendicular
to the horizontal stabilizer. Then glue the vertical stabilizer into the fuselage, using
a generous amount of 5 min. Epoxy. Apply thin epoxy to each of the two joints and
the entire bottom edge of the vertical stabilizer, use a generous amount to ensure
to strong bond.
