Toavoid scratching yournew airplane,donot
unwrap the pieces until they are needed for
assembly. Cover your workbench with an old
towel or brown paper, both to protect the
aircraftand toprotect thetable. Keepa couple
of jars or bowls handy to hold the small parts
after you open the bag.
Pleasetrialfitalltheparts. Makesureyouhave
the correct parts and that they fit and are

ARF is hand made from natural materials,
every plane is unique and minor adjustments
may have to be made. However, you should
find the fit superior and assembly simple.
The painted and plastic parts used in this kit
are fuel proof. However, they are not tolerant
of many harsh chemicals including the
following: paint thinner, C/A glue accelerator,
C/A glue debonder and acetone. Do not let
these chemicals come in contact with the
colors on the covering and the plastic parts.

Caution: this model is not a toy!
Ifyouare abeginner tothistype ofpowered model,pleaseask anexperienced modelflyerfor help
and support. If you attempt to operate the model without knowing what you are doing you could
easily injure yourself or somebody else. Please keep your safety and well-being in mind at all
times.
Important: before you start construction
Even if you have already built a large number of RC models please read right through these
instructions and check all the kit components against the parts list. We have taken great trouble to
keep construction as simple as possible, without making any compromises in the area of safety.
Note regarding the film covering
Minor creases or bubbles may develop in the film covering due to major fluctuations in weather
conditions (temperature, humidity etc.); in rare cases you may even find a slight warp in a
component. These minor faults are in the nature of film-covered built-up wooden structures, and
can easily be corrected using a heat gun, as commonly used for modelling.
Creases: Blow warm air over the area and rub down with a soft cloth.
Wing warp: Hold the panel twisted gently in the opposite direction to the warp, and apply
warm air to remove the creases from the covering.
Caution! do not heat the film more than is absolutely necessary. If the air or the iron is too hot, the
film may melt and holes may be formed.
This model is highly pre-fabricated and can be built in a very short time. However, the work which
youhaveto carryout is importantand mustbedone carefully.Themodelwill onlybe strong andfly
well if you complete your tasks competently - so please work slowly and accurately.
When self-tapping screws have to be screwed into wood, apply a little white glue to prevent
them shaking loose: just squirt white glue into the hole and fit the screw.
SAFETY PRECAUTION.
+ This is not a toy
+ Be sure that no other flyers are using your radio frequency.
+ The glow plug clip must be securely attached to the glow plug.
+ Do not flip the propeller with your fingers.
+ Keep loose clothing and wires away from the propeller.
+ Do not start the motor if people are near. Do not stand in line with the side of the propeller.

1. It is critical that your airplane be bal-
anced correctly. Improper balance will cause
your plane to lose control and crash.
THE CENTER OF GRAVITY IS LOCATED
63mm BACK FROM THE LEADING EDGE
OF THE WING.


2. Mount the wing to the fuselage. Using a
couple of pieces of masking tape, place them
on the top side of the wing 63mm back from
the leading edge, at the fuselage sides.


3. Turn the airplane upside down. Place
yourfingers onthe maskingtape andcarefully
lift the plane .
BALANCING.
Secure.
Bottom side.

Insert and secure
Accurately mark the balance point on the top
of the wing on both sides of the fuselage. The
balance point is located 63mm back from the
leadingedge.This isthebalancepointatwhich
yourmodel shouldbalancefor yourfirstflights.
Later, you may wish to experiment by shifting
the balance up to 10mm forward or back to
change the flying characteristics. Moving the
balance forward may improve the
smoothnessandarrow- liketracking,butit may
thenrequire morespeedfor takeoff andmake
it more difficult to slow down for landing.
Movingthe balanceaft makesthemodel more
agile with a lighter and snappier ”feel”. In any
case, please start at the location we
recommend .
 With the wing attached to the fuselage, all
parts of the model installed ( ready to fly), and
empty fuel tanks, hold the model at the
marked balance point with the stabilizer level.
Lift the model. If the tail drops when you
lift,themodel is“tailheavy” andyoumust add
weigh*tothenose.Ifthe nosedrops,itis“nose
heavy” and you must add weight* to the tail to
balance.
*Ifpossible,first attemptto balancethe model
by changing the position of the receiver
batteryand receiver.Ifyouareunabletoobtain
good balance by doing so, then it will be
necessary to add weight to the nose or tail to
achieve the proper balance point.



1. Completely chargeyour transmitterand
receiver batteries before your first day of fly-
ing.


2. Check every bolt and every glue joint in
your plane to ensure that everything is tight
and well bonded.


3. Double check the balance of the
airplane.


4. Check the control surface.


5. Check the receiver antenna . It should
be fully extended and not coiled up inside the
fuselage.


6. Properly balance the propeller.
