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 !

7- Stabilizer

7A

Slowly, slide the horizontal stabilizer through

the vertical stabilizer.

7B

Check the alignment of the horizontal stabilizer,

the distance must be equal on both sides (A=A’).

When you are satisfied with the alignment, use

a pencil to trace around the top and bottom of

the horizontal stabilizer where it meets the

vertical stabilizer. Remove the horizontal stabilizer.

Vertical stabilizer

Remove the horizontal stabilizer

7C

from the vertical stabilizer. Using a straight edge

and a sharp hobby knife, carefully cut away

the covering inside the lines which were marked

above. Be cautious not to cut into the wood-this

will weaken the structure.

Cut away only

the covering

both sides.

Decal application: See the label on top box

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.
