WARNING
Please be aware that this aeroplane is not a toy and if assembled or used incorrectly it is capable of causing
injury to people or property. WHEN YOU FLY THIS AEROPLANE YOU ASSUME ALL RISK & RESPONSIBILITY.
If you are inexperienced with basic R/C flight we strongly recommend you contact your R/C supplier and join your local
R/C Model Flying Club. R/C Model Flying Clubs offer a variety of training procedures designed to help the new pilot on
his way to successful R/C flight. They will also be able to advise on any insurance and safety regulations that may
apply.
To 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.
SUGGESTION
NOTE
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 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 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 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

OPTION 2: ENGINE MOUNT, FUEL TANK
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.
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.

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.
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.
Blow through one of the lines to ensure the fuel lines
have not become kinked inside the fuel tank
compartment.Air should flow 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.
1) Install the rubber grommets and brass collets into
the elevator, rudder and throttle servos. Test ?t the
servos into the servo tray. Trim the tray if necessary to ?

the back edge of the cowl with the marks you made on
the fuselage.
2) While keeping the back edge of the cowl flush 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 firmly 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 muffler and muffler extension onto the
engine and make the cutout in the cowl for muffler
clearance. Connect the fuel and pressure lines to the
carburetor, muffler and fuel filler valve.

2) Draw a center line onto the horizontal stabilizer.
Then put the horizontal into the fuselage.
3) Check the fit of the horizontal stabilizer in its slot.
Make sure the horizontal stabilizer is square and
centered to the fuselage by taking measurements, but
don't glue anything yet.
Check to mark sure the wing and stabilizer are
paralell. If they are not, lightly sand the opening in
the fuselage for the stabilizer until the stabilizer is
paralell to the wing, but don't glue anything yet.
5) With the horizontal stabilizer correctly aligned.
Apply a thin CA layer to the top and bottom of the
stabilizer in the fuselage.
6) Hinges for Elevator are glued the same way as the
aileron before (see page 4).
1) Using a modeling knife, carefully remove the film
covering from the tail slots at the rear of the fuselage.

1) Cut out the switch hole using a modeling knife. Use a
2mm drill bit and drill out the two mounting holes
through the fuselage side.
2) Secure the switch in place using the two machine
screws provided with the radio system.
3) 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.
4) 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.
5) 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.

Install the spinner backplate, propeller and spinner
cone. The spinner cone is held in place using two 3mm
x 8 mm machine screws.
BALANCING
1) It is critical that your airplane be balanced correctly.
Improper balance will cause your plane to lose control
and crash.
THE CENTER OF GRAVITY IS LOCATED 73MM
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 73mm 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 73mm 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
Screw the wing panel in position.

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.
Control throw Ailerons:
Low: 10mm up / down.
High: 12mm up / down.
CONTROL THROWS

CG
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.
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 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.

PRE-FLIGHT CHECK
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.
4) Check the control surface.
5) Check the receiver antenna. It should be fully
extended and not coiled up inside the fuselage.
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
flights with your TURBO BEAVER.

I/C FLINGT WARNINGS
NEVER fly near power lines,aerials or
other dangerous areas including airports,
motorways etc.
ALWAYS adjust the engine from behind
the propeller, and do not allow any part of
your body to be in line with the propeller.
Always operate in open areas, away from
factories, hospitals, schools, buildings
and houses etc. NEVER fly your aircraft
close to people or built up areas.
DO NOT dispose of empty fuel
containers on a fire, this can lead to an
explosion.
NEVER fly in wet conditions or on windy
or stormy days.
NEVER use damaged or deformed
propellers or spinners.
THE PROPELLER IS DANGEROUS.
Keep fingers, clothing (ties, shirt sleeves,
scarves) or any other loose objects that
could be caught or drawn in, away from
the propeller. Take care at ALL times.
Keep all onlookers (especially small
children and animals) well back from the
area of operation. This is a flying aircraft,
which will cause serious injury in case of
impact with a person or animal.
