Toavoidscratching your new airplane,donot
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 toprotectthe table.Keep acoupleof
jars or bowls handy to hold the small parts af-
ter you open the bag.
Pleasetrialfitallthe parts.Makesure youhave
the correct parts and that they fit and are
alignedproperly beforegluing! Thiswillassure
proper assembly. AT.6 TEXAN ARF is hand
made from natural materials, every plane is
unique and minor adjustments may have to
be made. However, you should find the fit su-
perior and assembly simple.
The painted and plastic parts used in this kit
are fuel proof. However, they are not tolerant

Caution: this model is not a toy!
If you are a beginner to this type of powered
model,please ask anexperienced modelflyer
forhelpand support. Ifyouattempt to operate
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
Even if you have already built a large number
ofRCmodels 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 ina veryshort time.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

INSTALLING THE STOPPER ASSEMBLY
11) The stopper has been pre-assembled
at the factory.
12) Using a modeling knife, cut one length
ofsiliconfuel line(thelength of siliconfuel line
iscalculated byhow theweighted clunkshould
restabout8mm away fromtherear of thetank
andmovefreely inside thetank). Connect one

end of the line to the weighted clunk and the
otherendto thenylonpick up tubein the stop-
per.
13) 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.
14) Carefullybend thethird nylontube down
ata 45degree angle(using acigarette lighter).
This tubewill beventtube tothe fuelingvalve.
When the stopper assembly is installed in the
tank, the top of the vent tube should rest just
belowthe top surfaceof the tank.It should not
touch the top of the tank.
18) 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 thetank shouldjust about
touch the back of the firewall.
17) Usingamodeling knife, cut3lengths of
fuel line 150mm long. Connect 2 lines to the 2
vent tubes and 1 line to the fuel pickup tube in
the stopper.
15) Test fit the stopper assembly into the
tank. It may be necessary to remove some of
the flashing around the tank opening using
amodeling knife. Ifflashing is present, make
sure none of it falls into the tank.
16) When satisfied with the alignment of
thestopperassembly tightenthe3mmx20mm
machine screw until the rubber stopper ex-
pandsand sealsthe tankopening. Donot over
tighten the assembly as this could cause the
tank to split.
