Caution: this model is not a toy!
If you are a beginner to this type of powered
model,please askan experiencedmodelflyer
forhelp andsupport.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 havealready built alarge number
ofRC modelspleaseread 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.
+ 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.
+Theglowplugclip mustbesecurelyattached
to the glow plug.
.
SAFETY PRECAUTION.
+ 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 standinlinewiththesideof thepropel-
ler.
+ Make engine adjustments from behind the
propeller only. Do not reach around the spin-
ningpropeller
Creases: Blowwarm airover thearea
and rub down with a soft
cloth.
Wing warp: Holdthepaneltwisted gently
in the opposite direction to
the warp, and apply warm
air to remove the creases
from the covering.
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.
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
taskscompetently -so pleaseworkslowlyand
accurately.
