Toavoid scratching yournew 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
aircraftand toprotect thetable. Keepa couple
of jars or bowls handy to hold the small parts
after you open the bag.
Pleasetrialfitalltheparts. Makesureyouhave
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
of many harsh chemicals including the
following: paint thinner, C/A glue accelerator,
C/A glue debonder and acetone. Do not let
these chemicals come in contact with the
colors on the covering and the plastic parts.

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.
Creases: Blowwarm airoverthearea
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 inavery shorttime.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.
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.

Do not secure the tank into place perma-
nently until after balancing the airplane. You
may need to remove the tank to mount the
battery in the fuel tank compartment
 9) To secure the fuel tank in place, ap-
plya beadofsilicon sealerto theforward area
of the tank, where it exits the fuselage behind
theengine mountingbox andto therearofthe
tank 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,the frontofthetankshould justabout
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
fueltankcompartment.Airshouldflow through
easily.
 5) 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.

INSTALLING THE THROTTLE PUSHROD
 1. Install one adjustable metal connector
through the third hole out from the center of
one servo arm, enlarge the hole in the servo
arm using a 2mm drill bit to accommodate the
servo connector. Remove the excess mate-
rial from the arm.
After installing the adjustable metal con-
nector apply a small drop of thin C/A to
the bottom nut. This will prevent the con-
nector from loosening during flight.
