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
Center line
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. Clean 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.

Install one clevis onto each of the aileron pushrod.
With the ailerons and the aileron servo in the neutral

A small piece of masking tape works well for this.
Cut off the excess length of each rod.
Ensure that the servo is centered. If necessary,
adjust the metal clevis so the aileron is also in
the neutral position.

ELEVATOR
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 and the end of the
elevator should not rub against the horizontal stabilizer.
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.
* WARNING: When removing any covering from the airframe, please
ensure that you secure the cut edge with CA or similar cement. This
will ensure the covering remain tight.

22. How to add noseweight
To get the correct C.G., Several strips of lead
weight were required in the nose of this model .
To minimize the amount of weight required, it
is desirable to position the weight as far forward
as possible. This can be done by making a
platform form left over basswood stick and 3.2mm
(1/8”) ply wood. Using 4x35mm bolts to mount the
engine would also be long enough to mount the
flatform. The lead should be permanently glued
on with epoxy.
IMPORTANT: Recheck the C.G. After the weight
has been installed.

Please do not clean your model with pure alcohol, only use liquid soap with water or use glass cleaner to
clean on surface of your model to keep the colour not fade.
CAUTIONS FOR SAFETY
Ensure the airfield is spacious enough.
Ensure the spinner and propeller are securely attached. Immediately disure defective propeller as well as deformed spinners.
Adjust the engine always from behind, but never from infront or the sides as rotating propeller may badly injure you.
Do not allow watching people to get too close to a rotating propeller.
Fully extend the transmitter and receiver antenna.
Always take off and landing your airplane into the wind.
Switch off the transmitter and receiver after landing.
Do not fly your airplane above people standing around.
BEFORE FLYING CHECK EVERYTHING
Before each flight, inspect the airplane for any loose parts. Check the hinges, make sure the pushrods are still firmly
attached, and check the engine mounting bolts. In general, check everything on the plane that might possibly come
loose.
WARNING: Do not put in a large-than recommended engine. A bigger engine does not necessarily mean better performance.
