Caution: this model is not a toy!
If you are a beginner to this type of powered
model,pleaseask an experienced modelflyer
forhelpandsupport.Ifyouattempttooperate
themodelwithout knowingwhatyouare doing
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
Evenif you have already built alarge number
ofRCmodelspleasereadrightthroughthese
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: Blowwarmair over thearea
and rub down with a soft
cloth.
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.
+The glow plug clip must be securely at-
tached 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.
Do not stand in line with the side of the pro-
peller.
+ Make engine adjustments from behind the
propeller only. Do not reach around the spin-
ningpropeller.
SAFETY PRECAUTION.
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,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
tasks competently - so please work slowly
and accurately.

You may need to remove the tank to mount
the battery in the fuel tank compartment.
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,where it exits thefuselagebehindthe
enginemounting boxandtotherearofthetank
at the forward bulkhead.
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,thefront of thetankshouldjustabout
touch the back of the firewall.

Tie wrap.
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.
5) Test fit the stopper assembly into the
tank. It may be necessary to remove some of
the flashing around the tank opening using
amodelingknife. If flashing is present, make
sure none of it falls into the tank.
6) When satisfied with the alignment of
thestopper assemblytightenthe 3mmx20mm
