WARNING! This radio controlled model is NOT a toy. If modified or flown carelessly it could go out of controll and
cause serious human injury or property damage. Before flying your airplane, ensure the air field is spacious enough.
Always fly it outdoors in safe areas and seek professional advice if you are unexperienced.
ACHTUNG! Dieses ferngesteuerte Modell ist KEIN Spielzeug! Es ist für fortgeschrittene Modellflugpiloten bestimmt,
die ausreichende Erfahrung im Umgang mit derartigen Modellen besitzen. Bei unsachgemässer Verwendung kann
hoher Personen- und/oder Sachschaden entstehen. Fragen Sie in einem Modellbauverein in Ihrer Nähe um
professionelle Unterstätzung, wenn Sie Hilfe im Bau und Betrieb benötigen. Der Zusammenbau dieses Modells ist
durch die vielen Abbildungen selbsterklärend und ist für fortgeschrittene, erfahrene Modellbauer bestimmt.

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.

11- JOINING THE WING
Without using Epoxy yet, trial fit the wing joiner into one
of the wing panels.
Next, slide the other wing half onto the dihedral brace until the
wing panels meet. If the fit is overly tight, it may be necessary to lightly
sand the dihedral brace.

12- JOINING THE WING continued
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. Using a paper towel, clean off the excess epoxy.
Please do not clean off the excess epoxy on the wing with strong solvent or pure alcohol
to keep the colour of your model not fade.
NOTE:

Push the horizontal stabilizer into the slot on the fuselage
as show. Check the alignment of the horizontal stabilizer
by measuring from a fixed point along the center line of
the fuselage to the leading edge on each side of the
horizontal stabilizer. The distance must be equal on both
sides . If not, adjust the stabilizer until the measurements
are the same (see picture below: A=A’).
When you are satisfied with the alignment, use
a pencil to trace around the top and bottom of
the stabilizer where it meets the fuselage (13B).
Cut away only

Remove the horizontal stabilizer
from the fuselage. 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 (13C).
Remove the left and right elevator out of the horizontal stabilizer.
Using a sharp hobby knife, carefully cut away the covering

fuselage.
Pull the rudder out of the vertical fin.

Remove the vertical stabilizer from the fuselage.
Using s sharp hobby knife, carefully cut away the
covering below the lines which were drawn in the
previous steep. Do not cut into the woods as this
will affect the structural integrity of the stabilizer (15A).
Without using glue yet, push the elevator and its
hinges into the hinge slots in trailing edge of the
horizontal stabilizer (15C).

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.
