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.

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.
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.
Cut away only
the covering

NOTE: You may need to open up the slots of the

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.

Note: Cut out the stickers and apply them in the proper area. Do not peel the backing paper off all at once. Peel off one corner of the backing and cut off with
scissors. Arrange sticker on model and when satisfied adhere the corner without backing.
Carefully peel back the rest of the backing while at the same time adhering the rest of the sticker.
Try not to make air bubbles, if there are some, carefully puncture sticker (center of bubble) but not model surface with the tip of the knife or sharp pin and
squeeze out the air.
At curves stretch sticker and apply a little heat so that no ceases occur. Cut off the excess that is produced.
