Caution: this model is not a toy!
If you are a beginner to this type of powered
model,please askan experienced 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
Evenifyou have already built a large number
ofRC models please readright 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: Blowwarm airover thearea
and rub down with a soft
cloth.
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 ina veryshorttime. 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 -soplease workslowly 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.
REPLACEMENT LARGE PARTS
Wing warp: Holdthepaneltwistedgently
in the opposite direction to

air to remove the creases

1) The stopper has been pre-assembled
at the factory.
2) Using a modeling knife, cut one length
ofsilicon fuel line(thelength of siliconfuelline
iscalculatedbyhowtheweightedclunk should
restabout 8mm awayfromthe rear ofthe tank
andmove freely insidethe tank). Connectone
end of the line to the weighted clunk and the
otherend to thenylonpick up tubeinthe stop-
per.

3) Carefully bend the second nylon tube
up at a 45 degree angle (using a cigarette
lighter). This tube will be the vent tube to the
muffler.
4) Carefullybend thethird nylontube down
ata 45degree angle(using acigarette lighter).
This tubewill beventtube tothefueling valve.
When the stopper assembly is installed in the
tank, the top of the vent tube should rest just
belowthe top surface ofthetank. It shouldnot
touch the top of the tank.

6. When satisfied with the alignment of the
stopper assembly tighten the 3mm x 20mm
machine screw until the rubber stopper ex-
pandsand sealsthe tankopening. Donot over
tighten the assembly as this could cause the
tank to split.
8. Feed three lines through the fuel tank
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 frontof thetankshouldjustabout
touch the back of the firewall.
7. Using a modeling knife, cut 3 lengths of
fuel line 150mm long. Connect 2 lines to the 2
vent tubes and 1 line to the fuel pickup tube in
the stopper.
Blow through one of the lines to ensure
the fuel lines have not become kinked inside
the fuel tank compartment. Air should flow
througheasily.
9. To secure the fuel tank in place, apply a
bead of silicon sealer to the forward area of
thetank, whereitexits thefuselage behindthe
enginemountingbox andtotherearof thetank
