This model is highly pre-fabricated and can be built in
a very 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 y 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 t the screw.
Caution: This model is not a toy!
If you are a beginner to this type of powered model,
please ask an experienced model yer for help and
support. If you attempt to operate the model without
knowing what you 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 built a large number of RC models
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 lm covering
Minor creases or bubbles may develop in the lm
covering due to major uctuations in weather conditions
(temperature, humidity etc.); in rare cases you may
even nd a slight warp in a component. These minor
faults are in the nature of lm-covered built-up wooden
structures, and can easily be corrected using a heat
gun, as commonly used for modelling.
Creases: Blow warm air over the area and rub
down with a soft cloth.
Wing wrap: Hold the panel twisted gently in
the opposite direction to the wrap,and
apply warm air to remove the creases
from the covering.
Caution! do not heat the lm more than is absolutely
necessary. If the air or the iron is too hot, the lm may
melt and holes may be formed.
+ This is not a toy.
+ Be sure that no other yers 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 attached to the
glow plug.
+ Do not ip the propeller with your ngers.
+ Keep loose clothing and wires away from the propel-
ler.
+ Do not start the engine if people are near. Do not
stand in line with the side of the propeller.
+ Make engine adjustments from behind the propeller
only. Do not reach around the spinning propeller.

1. INSTALLING THE STOPPER ASSEMBLY
IV. FUEL TANK
152mm
1) The stopper has been pre-assembled at the
factory.
2) Using a modeling knife, cut one length of silicon
fuel line (the length of silicon fuel line is calculated by
how the weighted clunk should rest about 8mm away
from the rear of the tank and move freely inside the
tank). Connect one end of the line to the weighted
clunk and the other end to the nylon pick up tube in
the stopper.
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 mufer.
4) Carefully bend the third nylon tube down at a 45
degree angle (using a cigarette lighter). This tube will
be vent tube to the fueling valve.
When the stopper assembly is installed in the tank, the
top of the vent tube should rest just below the top sur-
face of the tank. It should not touch the top of the tank.

5) Test t the stopper assembly into the tank. It may
be necessary to remove some of the ashing around
the tank opening using a modeling knife. If ashing is
present, make sure none of it falls into the tank.
6) When satised with the alignment of the stopper
assembly tighten the 3mm x 20mm machine screw until
the rubber stopper expands and seals the tank opening.
Do not over tighten the assembly as this could cause
the tank to split.

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 accommo-
date the servo connector. Remove the excess material
from the arm.
After installing the adjustable metal connector apply
a small drop of thin C/A to the bottom nut. This will
prevent the connector from loosening during ight.
2. INSTALLING THE THROTTLE - CABLE
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.
8) Feed three lines through the fuel tank compart-
ment and through the pre-drilled hole in the rewall. 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 front of the tank should just about touch
the back of the rewall.
Blow through one of the lines to ensure the fuel lines
have not become kinked inside the fuel tank compart-
ment. Air should ow through easily.
9) To secure the fuel tank in place, apply a bead of
silicon sealer to the forward area of the tank, where it
exits the fuselage behind the engine mounting box and
to the rear of the tank at the forward bulkhead.
Do not secure the tank into place permanently until after
balancing the airplane. You may need to remove the
tank to mount the battery in the fuel tank compartment.

V. INSTALLING THE CANOPY
1) Slide the berglass cowl over the engine and
line up the back edge of the cowl with the marks you
made on the fuselage.
Push in
Position the canopy so the rear frame on the
canopy is aligned with the rear edge of the cockpit
opening. Use canopy glue to secure the canopy
to the canopy hatch. Use low-tack tape to hold the
canopy in position until the glue fully cures. Wrap
the tape completely around the canopy hatch, as
the tape does not stick well to the covering. We
used balsa sticks to hold the lower edges of the
canopy tightly against the canopy hatch.
2) While keeping the back edge of the cowl ush
with the marks, align the front of the cowl with the
crankshaft of the engine. The front of the cowl should
be positioned so the crankshaft is in nearly the middle
of the cowl opening. Hold the cowl rmly in place using
pieces of masking tape.
3) Slide the cowl back over the engine and secure
it in place using four wood screws. See picture below.
4) Install the mufer and mufer extension onto
the engine and make the cutout in the cowl for mufer
clearance. Connect the fuel and pressure lines to the
carburetor, mufer and fuel ller valve.

into 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 protec-
tive foam to protect them from vibration. Use a rubber
band or masking tape to hold the foam in place.
 3) Position the battery pack and receiver behind
the fuel tank. Use two tie wraps to hold the battery and
receiver securely in place as pictures below.
Do not permanently secure the receiver and battery
until after balancing the model.

 1) It is critical that your airplane be balanced cor-
rectly. Improper balance will cause your plane to lose
control and crash.
THE CENTER OF GRAVITY IS LOCATED
108MM BACK FROM THE LEADING EDGE OF THE
WING.
 2) Mount the wing to the fuselage. Using a couple
of pieces of masking tape, place them on the top side
of the wing 108mm back from the leading edge, at the
fuselage sides.
 3) Turn the airplane upside down. Place your ngers
on the masking tape and carefully lift the plane.
Accurately mark the balance point on the top of the
wing on both sides of the fuselage. The balance point
is located 108mm back from the leading edge. This is
the balance point at which your model should balance
for your rst ights. Later, you may wish to experiment
by shifting the balance up to 10mm forward or back to
change the ying characteristics. Moving the balance
forward may improve the smoothness and arrow- like
tracking, but it may then require more speed for take
off and make it more difcult 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 location we recommend.
With the wing attached to the fuselage, all parts of the
model installed ( ready to y), and empty fuel tanks,
hold the model at the marked balance point with the
stabilizer level.
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.
*If possible, first attempt to balance the model by
changing the position of the receiver battery and re-
ceiver. If you are unable to obtain good balance by
doing so, then it will be necessary to add weight to
the nose or tail to achieve the proper balance point.
BALANCING

SUPER DECATHLON Item code: BH150. Instruction Manual

 1) Completely charge your transmitter and receiver
batteries before your rst day of ying.
 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.
 4) Check the control surface.
 5) Check the receiver antenna . It should be fully
extended and not coiled up inside the fuselage.
 6) Properly balance the propeller.
We wish you many safe and enjoyable ights with
your SUPER DECATHLON.
PRE-FLIGHT CHECK
 1) We highly recommend setting up a plane using
the control throws listed.
 2) The control throws should be measured at the
widest point of each control surface.
 3) Check to be sure the control surfaces move in
the correct directions.
