Toavoid scratching yournew airplane,do not
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.
Please trial fit all the parts. Make sure you

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.

SAFETY PRECAUTION.
Caution: this model is not a toy!
If you are a beginner to this type of powered
model,please askan experiencedmodelflyer
forhelpandsupport.Ifyouattempttooperate
themodel withoutknowingwhat youaredoing
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
Evenifyou havealreadybuilt alarge number
ofRCmodelspleaseread rightthrough 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: Blowwarm airoverthearea
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
bebuilt inavery shorttime.However,the work
which you have to carry out is important and
must be done carefully. The model will only
be strong and fly 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.
