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

C/A glue.
* Apply drops of thin CA to the top and bottom of each
hinge. Do not use CA accelerator. After the CA has fully
hardened, test the hinges by pulling on the aileron.
* Test fit the ailerons to the wing with the hinges. If the
hinges don’t remain centered, stick a pin through the
middle of the hinge to hold it in position.
* Secure nylon hinges with instant glue, being careful
not to glue the wing and aileron together.
* Align the center line of main wing with aileron.
Make certain the hinges are adequately secured
with glue. if they come loose in flight accidents may
result.
WARNING
* Install the rubber grommets and brass eyelets on to
the aileron servos.
* Using a modeling knife, remove the covering from
over the pre-cut servo arm exit hole on the aileron servo
tray / hatch. This hole will allow the servo arm to pass
through when installing the aileron pushrods.
* Place the servo into the servo tray. Center the servo
within the tray and drill 1.5mm pilot holes through the
block of wood for each of the four mounting screws
provided with the servo.
* Using the thread as a guide and using masking tape,
tape the servo lead to the end of the thread: carefully
pull the thread out. When you have pulled the servo
lead out, remove the masking tape and the servo lead
from the thread.
* Place the servo into the servo tray/ hatch into the
servo box on the bottom of the wing and drill 1.5mm
pilot holes through the tray and servo box for each of the

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.

INSTALLING THE THROTTLE PUSHROD
Pushrod wire
Pushrod choke
* Locate the long piece of wire used for the throttle
pushrod. One end of the wire has been pre-bend in to a
"Z" bend at the factory. This "Z" bend should be inserted
into the throttle arm of the engine when the engine is
fitted onto the engine mount. Fit the engine to the
engine mount using the screws provided.
Pushrod choke
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 ?
t your servos.
2) Mount the servo to the tray using the mounting
screws provided with your radio system.

1) Slide the fiberglass cowl over the engine and line up
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.
Drill four 2.5mm pilot holes through both the cowl and
the side edges of the firewall. Using a 3mm drill bit,
enlarge the four holes in the cowling.

* 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 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 flight.

8. INSTALLING HORIZONTAL STABILIZER
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.
Make sure that you do not remove any wood from the
slots as this will affect the alignment of the tail.
