Toavoid scratching yournewairplane, 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 air-
craftand to protectthetable. Keep acoupleof
jars or bowls handy to hold the small parts af-
ter you open the bag.

Caution: this model is not a toy!
If you are a beginner to this type of powered
model,please askanexperienced modelflyer
forhelp and support. Ifyou attempt tooperate
themodel withoutknowing whatyou aredoing
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
Evenifyouhave already built a large number
ofRC models please readrightthrough 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 airover thearea
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 inaveryshorttime.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.
+ This is not a toy
+ Be sure that no other flyers are using your
radio frequency.
+ Do not smoke near fuel
+ Store fuel in a cool, dry place, away from
children and pets.
+ Wear safety glasses.
+Theglow plugclipmust besecurelyattached
to the glow plug.
+ Do not flip the propeller with your fingers.
+ Keep loose clothing and wires away from
thepropeller.
+ Do not start the engine if people are near.
Donot stand in linewith the side ofthe propel-
ler.
+ Make engine adjustments from behind the
propeller only. Do not reach around the spin-
ningpropeller.

the masking tape or T-pins used to hold the
stabilizer in place and carefully inspect the
glue joints. Use more epoxy to fill in any
gaps that were not filled previously and
clean up the excess using a paper towel and
rubbingalcohol.
5. When you are sure that everything is
aligned correctly, mix up a generous amount
of 30 minute epoxy. Apply a thin layer to the
topand bottom of thestabilizer mounting area
and to the stabilizer mounting platform sides

ments one more time before the epoxy cures.
Remove any excess epoxy using a paper

 4. Remove the stabilizer. Using the lines
youjustdrew as a guide,carefully remove the
coveringfrom betweenthemusing amodeling
knife.
When cutting through the covering to
remove it, cut with only enough pressure
to only cut through the covering it’s self.
Cutting into the balsa structure may
weaken it. This could lead to possible fail-
ure during flight.
Remove covering
Check to mark sure the wing and stabi-
lizer are paralell. If they are not, lightly sand
