unique and minor adjustments may have to
be made. However, you should find the fit su-

Caution:
this model is not a toy!
Ifyouare abeginner tothis typeofpowered model,please askan experiencedmodel flyer forhelp
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 isimportantand mustbe donecarefully.The modelwillonly bestrong 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.
+ Wear safety glasses.
+ 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.
+ Make motor adjustments from behind the propeller only. Do not reach around the spinning
propeller.

 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.
Accurately mark the balance point on the top
of the wing on both sides of the fuselage. The
balance point is located 27mm back from the
leadingedge.This isthe balancepointatwhich
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 smooth-
ness and arrow- like tracking, but it may then
require more speed for take off and make it
moredifficult toslow downfor landing.Moving
the balance aft makes the model more agile
with a lighter and snappier ”feel”. In any case,
please start at the location we recommend .
Lift the model. If the tail drops when you
lift,themodel is“tail heavy” andyou mustadd
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 bat-
tery and receiver. If you are unable to obtain
good balance by doing so, then it will be nec-
essary to add weight to the nose or tail to
achieve the proper balance point.

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
27MM 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 27mm back from
the leading edge, at the fuselage sides.


3. Turn the airplane upside down. Place
your fingers on the masking tape and care-
fully lift the plane .
