SUGGESTION

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.

NOTE:

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. The

SUPER CUB PA-18 SCALE 1:4 Size 30cc 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 superior 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 following: paint thinner, C/A

glue accelerator, C/A glue debonder and acetone. Do

not let these chemicals come in contact with the

colors on the covering and the plastic parts.

SAFETY PRECAUTION:

• 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.

PREPARATIONS

Use a covering iron with a covering sock on

high heat to tighten the covering if necessary.

Apply pressure over sheeted areas to

thoroughly bond the covering to the wood.

INSTALLING THE AILERONS AND Flaps

1. 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.

SERVOS

1. Install the rubber grommets and brass eyelets onto

the aileron servo.

2. 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.

3. Place the servo into the servo tray. Center the servo

within the tray and drill pilot holes through the block

of wood for each of the four mounting screws

provided with the servo.

4. 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.

5. Place the aileron servo tray / hatch into the servo

box on the bottom of the wing and drill pilot

holes through the tray and the servo box for

each of the four mounting screws. Secure the

servo tray in place using the mounting screws

provided .

6. Repeat step # 2 - # 5 to install the second aileron

servo in the opposite wing half.

Make certain the hinges are adequately secured with glue. If

they come loose in flight accidents may result.

Secure nylon hinges with instant glue, being careful

not to glue the wing and airleron together.

Apply instant glue (CA glue, super glue).

3. Turn the airplane upside down. Place your fingers

on the masking tape and carefully lift the plane.

4. If the nose of the plane falls, the plane is nose

heavy. To correct this first move the battery pack

further back in the fuselage. If this is not possible

or does not correct it, stick small amounts of lead

weight on the fuselage under the horizontal

stabilizer. If the tail of the plane falls, the plane is

tail heavy. To correct this, move the battery and

receiver forward or if this is not possible, stick

weight into the firewall. When balanced correctly,

the airplane should sit level or slightly nose down

when you lift it up with your fingers.

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 109mm

(4.3 in) BACK FROM THE LEADING EDGE OF

THE WING, AT THE FUSELAGE. BALANCE A

PLANE UPSIDE DOWN WITH THE FUEL TANK

EMPTY.

2. Mount the wing to the fuselage. Using a couple of

pieces of masking tape, place them on the top

side of the wing 109mm (4.3 in) back from the

leading edge, at the fuselage sides.

SUPER CUB

Instruction Manual

CONTROL THROWS

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.

LATERAL BALANCE

After you have balanced a plane on the C.G.

You should laterally balance it. Doing this will

help the airplane track straighter.

1. Turn the airplane upside down. Attach one loop

of heavy string to the engine crankshaft and

one to the tail wheel wire. With the wings level,

carefully lift the airplane by the string. This may

require two people to make it easier.

2. If one side of the wing fall, that side is heavier

than the opposite. Add small amounts of lead

weight to the bottom side of the lighter wing

half's wing tip. Follow this procedure until the

wing stays level when you lift the airplane.

Main Gear Dimensional Detail

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 5mm 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.

MOUNTING THE COWL

1. Remove the muffler and needle valve assembly

from the engine. Slide the fiberglass cowl over the

engine.

2. Measure and mark the locations to be cut out for

engine head clearance, needle valve, muffler.

Remove the cowl and make these cutouts using a

rotary tool with a cutting disc and a rotary sanding

drum attachment.

3. Slide the cowl back into place. 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 the middle of the precut opening. Hold the cowl

firmly in place using several pieces of masking

tape.

Enlarging the holes through the cowl will prevent

the fiberglass from splitting when the mounting

screws are installed.

6. Slide the cowl back over the engine and secure it

in place using four screws.

7. Install the muffler. Connect the fuel and pressure

lines to the carburator, muffler and fuel filler

valve. Tighten the screws completely.

4. While holding the cowl firmly in position, drill

four 1,6mm pilot holes through both the cowl

and the side edges of the firewall.

5. Using a 3mm drill bit, enlarge the four holes in

the cowling.

INSTALLING THE SWITCH

1. The switch should be mounted on the fuselage

side, opposite the muffler, close enough to the

receiver so the lead will reach. Use the face plate

of the switch cut out and locate the mounting

holes.

2. 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.

3. Secure the switch in place using the two machine

screws provided with the radio system.

INSTALLING THE RECEIVER AND BATTERY

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.

Do not permanently secure the receiver and battery

until after balancing the model.

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.

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.

9. Secure the fuel tank.
