Landinggear.....
Toavoid scratching your new airplane, do not
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 to protect the table. Keep a coupleof
jars or bowls handy to hold the small parts af-
ter you open the bag.
Pleasetrialfitalltheparts.Makesureyouhave
the correct parts and that they fit and are
alignedproperly beforegluing!This willassure
proper assembly.Thermal 3.0 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 follow-
ing:paintthinner,C/Aglueaccelerator,C/Aglue
debonderandacetone. Donot letthese chemi-
cals come in contact with the colors on the

Caution: this model is not a toy!
If you are a beginner to this type of powered
model,please ask an experienced model flyer
forhelpandsupport.Ifyou attempt to operate
themodel without knowingwhatyou are 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
Even if you have already built a large number
ofRCmodels please read right 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.
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 short 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
taskscompetently - sopleasework 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.
Creases: Blowwarm air over the area
and rub down with a soft
cloth.
SAFETY PRECAUTION.
Wing warp: Holdthepaneltwisted gently
in the opposite direction to
the warp, and apply warm
air to remove the creases
from the covering.
REPLACEMENT LARGE PARTS
+ This is not a toy
+ Be sure that no other flyers are using your
radio frequency.
+ Wear safety glasses.
+ Keep loose clothing and wires away from
thepropeller.
+ Do not start the motor if people are near.
Donot stand in line with the side of the propel-
ler.
+ Make motor adjustments from behind the
propeller only. Do not reach around the spin-
ningpropeller.

1. Plug the servo leads and the switch
leadinto the receiver. You may want to plug
anaileronextensioninto the receiver to make
plugging in the aileron servo lead easier
when you are installing the wing . Plug the
battery pack lead into the switch.


2. Wrap the receiver and battery pack in
the protective foam to protect them from vi-
bration.Use a rubber band or masking tape to
hold the foam in place.


3. Position the battery pack and receiver
in as pictures below

4. Using a 2mm drill bit, drill aholethrough
the side of the fuselage, near the receiver, for
the antenna to exit.
1.Locatethe aluminium wing dihedral brace.
*** Test fit the aluminium tube dihedral brace
into each wing haft. The brace should slide in
easily. If not, use 220 grit sand around the
edges and ends of the brace until it fits prop-
erly.

1) We highly recommend setting up a
plane using the control throws listed.


2) The control throws should be meas-
ured at the widest point of each control sur-
face.


3) Check to be sure the control surfaces
move in the correct directions.

PRE-FLIGHT CHECK.


1) Completely charge your transmitter and
receiver batteries before your first day of fly-
ing.


2) Check every bolt and every glue joint in
your plane to ensure that everything is tight
and well bonded.


3) Double check the balance of the
airplane.


6) Properly balance the propeller.
We wish you many safe and enjoyable
flights with your Thermal 3.0.


4) Check the control surface.


5) Check the receiver antenna . It should
be fully extended and not coiled up inside the
fuselage.
Accuratelymark the balance point on the top
ofthe wing onboth sides ofthefuselage. The
balancepoint is located 65mm back fromthe
leading edge. This is the balance point at
whichyourmodel shouldbalance foryour first
flights. Later, you may wish to experiment by
shifting the balance up to 10mm forward or
back to change the flying characteristics.
Movingthe balance forwardmay improve the
smoothness and arrow- like tracking, but it
may then require more speed for take off
and make it more difficult to slow down for
landing. Moving the balance aft makes the
model more agile with a lighter and snappier
”feel”. In any case, please start at the loca-
tion we recommend .
 With the wing attached to the fuselage, all
partsof the model installed ( readytofly),and
empty fuel tanks, hold the model at the
markedbalance point with the stabilizerlevel.
Lift the model. If the tail drops when you
lift, the model is “tail heavy” and you must
add weigh* to the nose. If the nose drops, it
is “nose heavy” and you must add weight* to
the tail to balance.
*Ifpossible, firstattemptto balancethemodel
by changing the position of the receiver bat-
tery and receiver. If you are unable to obtain
goodbalance by doing so, then it will be nec-
essary to add weight to the nose or tail to
achieve the proper balance point.

1) It is critical that your airplane be bal-
anced correctly. Improper balance will cause
your plane to lose control and crash.
THE CENTER OF GRAVITY IS LOCATED
65MM BACK FROM THE LEADING EDGE
OF THE WING.


2) Mount the wing to the fuselage.Usinga
coupleof pieces of masking tape, place them
on the top side of the wing 65 mm back from
the leading edge, at the fuselage sides.


3. Turn the airplane upside down. Place
your fingers on the masking tape and care-
fully lift the plane .
