T o avoid 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 aircraft and to protect the table. Keep a couple of
jars or bowls handy to hold the small parts after you open the bag.
Please trial fit all the parts. Make sure you have
the correct parts and that they fit and are
aligned properly before gluing! This will assure
proper assembly.SILENCE TWISTER ARF is

Silence Twister - Item code: BH 110 . Instruction Manual
Caution: this model is not a toy!
If you are a beginner to this type of powered
model, please ask an experienced model flyer
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 already 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 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: Blow warm air over the area
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.
+ 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 attached
to the glow plug.
+ Do not flip the propeller with your fingers.
+ Keep loose clothing and wires away from
the propeller.
+ 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.
SAFETY PRECAUTION.
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 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.
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.

INSTALLING THE STOPPER ASSEMBLY
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 muffler .
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.
FUEL TANK.
When the stopper assembly is installed
in the tank, the top of the vent tube should
rest just below the top surface of the tank.
It should not touch the top of the tank.

6) When satisfied 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.
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
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 front of the tank should just about
touch the back of the firewall.
5) Test fit the stopper assembly into the
tank. It may be necessary to remove some of
the flashing around the tank opening using
a modeling knife. If flashing is present, make
sure none of it falls into the tank.

1. Plug the servo leads and the switch
lead into the receiver. You may want to
plug an aileron extension 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 protective 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.
4. Using a 2mm drill bit, drill a hole through
the side of the fuselage, near the receiver,
for the antenna to exit.

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
95MM 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 95mm back from
the leading edge, at the fuselage sides.
3. Turn the airplane upside down. Place
your fingers 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 95mm back from the
leading edge. This is the balance point at
which your model should balance for your first
flights. Later, you may wish to experiment by
shifting the balance up to 10mm forward or
back to change the flying 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 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 location we recommend .

CONTROL THROWS.
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 surface.
3) Check to be sure the control surfaces
move in the correct directions.
PRE-FLIGHT CHECK.
Flap : 35mm down
Ailerons : 15mm up 15mm down
Elevator : 15mm up 15 mm down
Rudder : 25mm right 25mm left
1) Completely charge your transmitter and
receiver batteries before your first day of flying.
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 Silence Twister.
4) Check the control surface.
5) Check the receiver antenna . It should
be fully extended and not coiled up inside the
fuselage.
With the wing attached to the fuselage, all
parts of the model installed ( ready to fly), 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 receiver. If you are unable to obt ain
good balance by doing so, then it will be necessary to add weight to the nose or tail to
achieve the proper balance point.
