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 !

1- Using a pencil, mark the center of the brace.
2- Trial fit the wing joiner into one of the wing panels. It should insert
smoothly up to the center line marked above.
3- Slide the other wing half onto the dihedral brace until the wing panel meet.
If the fit is over tight, it may be necessary to lightly sand the dihedral brace.
4- Check for the correct dihedral angle.
5- Mix approximately 30 minute epoxy and apply a generous amount of
epoxy into the wing joiner cavity of one wing half.
6- Coat one half of the dihedral brace with epoxy up to the center line. Install
the epoxy-coated side of the dihedral brace into the wing joiner cavity up to
the center line, marking sure that the “V” of the dihedral brace is positioned correctly
7- Do the same way with the other wing half.
8- Carefully slide the wing halves together, ensuring that they are accurately aligned.
Firmly press the two halves together, allowing the excess epoxy to run out. Clear off
the excess epoxy.
IMPORTANT: Please do not clean off the excess epoxy on the wing with strong solvent or
pure alcohol, only use kerosene to keep the colour of your model not fade.

1-Trial fit the horizontal stabilizer into the fuselage.
Use a pencil to carefully trace around the top
and bottom of the horizontal stabilizer where it
meets the fuselage.
2-Remove the horizontal stabilizer from the fuselage,
carefully cut away the covering inside the lines
which were marked in steep 1.
3-Speared epoxy onto the bottom and top of the
horizontal stabilizer along the area where the
covering was removed in the previous step and to
the fuselage where the horizontal stabilizer
mounts.
4-Install the horizontal stabilizer into the fuselage
and adjust the alignment as described in step 1.

Securely glue together. If coming off
during flight, you lose control of your
air plane.
Apply a thin layer of machine oil or petroleum jelly to only the pivot point of the hinges on the elevator, then push the
elevator and its hinges into the hinge slots in the trailing edge of the horizontal stabilizer. There should be a minimal
hinge gap.
When satisfied with the and alignment, hinge the elevator to the horizontal stabilizer using 5 minute epoxy. Make sure
to apply a thin layer of epoxy to the top and bottom of both hinges and to inside the hinge slots. Repeat the previous
procedures to hinge the second elevator to the other side of the horizontal stabilizer.

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.
