Caution: this model is not a toy!
If you are a beginner to this type of powered
model,please askan experiencedmodel flyer
forhelpand support.If youattempt to operate
themodel withoutknowing whatyouaredoing
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
ofRCmodels pleaseread rightthroughthese
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: Holdthepaneltwisted gently
in the opposite direction to
the warp, and apply warm
air to remove the creases
from the covering.
+ This is not a toy

SAFETY PRECAUTION.
This model is highly pre-fabricated and can
bebuilt inaveryshorttime. However, thework
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.
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.

compartment and through the pre-drilled hole
in the firewall. Pull the lines out from behind
the engine, while guiding the fuel tank into
place. Push the fuel tank as far forward as
possible,the frontofthetankshould justabout
touch the back of the firewall.
