 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 Tucano 40 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.

  WING ASSEMBLY

PARTS REQUIRED

•   (2) Wing halves with ailerons.

•   (1) Dihedral brace.

•   (1) Red self adhesive Trim Tape.

•   (4) Blocks of wood : 20mm x 25mm.

•   (8) Screws 2mm x 12mm.

  INSTALLING THE AILERON SERVOS

1. Install the rubber grommets and brass eyelets 

onto the aileron servo.

2. Turn the wing panel right side up. Using a 

modeling knife, remove the covering from over 

the precut servo lead exit hole in the root rib and 

the top of the wing sheeting. This hole will allow 

the servo leads to pass through when the wing 

halves are joined.

3.  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.

5.  Place the servo into the servo tray. Center the 

servo within the tray and drill 1,6mm pilot holes 

through the block of wood for each of the four 

mounting screws provided with the servo.

6.  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.

7. Place the aileron servo tray / hatch into the 

servo box on the bottom of the wing and drill 

1,6mm 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 (2mm x 12mm).

8.  Repeat step # 2 - # 7 to install the second 

aileron servo in the opposite wing half. 

9. Using masking tape, tape the servo leads on to 

the top of the wing.

3.   Test fit the dihedral brace into the carton tube 

in each wing half. The brace should slide into 

each wing half up to the center line. If it does 

not, remove the brace and lightly sand the 

edges and tips until the proper fit is obtained.

4.   Test fit both of the wing halves together with 

the dihedral brace temporarily installed. Do not 

glue it in at this time! The wing halves should fit 

together tight with little or no gaps in the center 

section joint. If the center section joint is not 

tight, remove the wing halves and lightly sand 

the edges and tips of the dihedral brace. Test 

fit the wing halves together with the dihedral 

brace installed again. Repeat until you are 

satisfied with the fit of the wing halves. The 

proper dihedral is built into the two root ribs 

and should not be altered.

 INSTALLING THE DIHEDRAL BRACE

1.  Look carefully at the surface of each root rib on 

both wing halves. Notice how the excess 

covering material overlaps onto them. Using a 

modeling knife, carefully cut out away the 

covering from both root ribs. Iron the covering 

down so that it does not pull away from the 

ribs.

It is important that the excess covering be 

removed from the root ribs. This will ensure an 

adequate wood to wood glue joint.

2.  Using a ruler and a pen, locate and mark the 

center line of the dihedral brace. Draw the 

vertical line at this location on each side of the 

brace.

 JOINING THE WING HALVES

1.   Mix a generous amount of 30 minute epoxy. 

Working with only one wing half for now, apply 

a thin layer of epoxy inside the carton tube and 

to only half of the dihedral brace. Make sure to 

cover the dihedral brace top and bottom as well 

as the sides, and use enough epoxy to fill any 

gaps.

2.  Slide the dihedral brace into the carton tube up 

to the center line. Remove any excess epoxy 

before it dries using a paper towel and rubbing 

alcohol. Allow the epoxy to cure before 

proceeding.

3. Once the epoxy has cured, trial fit both wing 

halves together to double check that the wing 

halves still fit correctly.

4.  Mix a generous amount of 30 minute epoxy. 

Apply a thin layer of epoxy to the exposed half 

of the dihedral brace, the inside of the carton 

tube and the entire surface of both root ribs. 

Make sure to use enough epoxy to fill any 

gaps.

5.  Slide the two wing halves together and carefully 

align them at the leading and trailing edges. 

Wipe away any excess epoxy using a paper 

towel and rubbing alcohol. Use masking tape to 

hold the two wing halves in place until the 

epoxy cures.

6.  When the epoxy has fully cured, double check 

the center section joint. If any gaps are present, 

mix a small amount of 30 minute epoxy and 

carefully fill any remaining gaps. Remove the 

excess epoxy using a paper towel and rubbing 

alcohol. Allow the epoxy to fully cure before 

proceeding. 

7.  Apply the trim tape to the center section of the 

wings where they join.

·  (1) Metal clunk.

·  (1) Silicon tube.

·  (1) Pre-assemble stopper.

·  (1) 165mm x 250mm foam.

 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

     

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.

 

INSTALLING THE THROTTLE PUSHROD HOUSING

1. Place the engine into the engine mount and align 

it properly with the front of the cowling. The 

distance from the firewall to the front of the 

engine thrust washer should 100mm.

    If your engine is equipped with a remote needle 

valve, we suggest installing it into the engine at 

this time.

2.  When  satisfied  with  the  alignment  of  the  engine, 

use a pencil and mark the mounting hole location 

onto the firewall, where the throttle pushrod will exit.

3. Now, remove the engine. Using a 5mm drill bit, 

drill  holes  through  the  firewall  and  the  forward 

bulkhead at the marks made.

4.  Slide  the  pushrod  housing  through  the  hole  in 

the  firewall,  through  the  hole  in  the  forward 

bulkhead, and into the servo compartment.

5. Apply a couple of drops of thin C/A to the pushrod
    housing where it exits the firewall and where it 

passes through the forward bulkhead. This will 

secure the housing in place.

6. Using a modeling knife, cut off the nylon 

pushrod housing 26mm in front of the servo tray.

HORIZONTAL STABILIZER INSTALLATION 

PARTS REQUIRED

·  (1) Horizontal stabilizer with Elevator halves.
1. Using a modeling knife, cut away the covering 

from the fuselage for the stabilizer and remove it.

8. Insert the 90 degree bend down through the hole in 

the servo arm. Install one nylon snap keeper over 

the wire to secure it to the arm. Install the servo 

arm retaining screw and remove the masking tape 

from the aileron.

9. Repeat step # 4 - # 11 to install the second aileron 

linkage. After both linkages are completed, connect 

both of the aileron servo leads using a Y-harness 

you have purchased separately.

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.

4. With the horizontal stabilizer correctly aligned, 

mark the shape of the fuselage on the top and 

bottom of the tail plane using a water soluble / 

non-permanent felt-tip pen.

!

5. Remove the stabilizer. Using the lines you just 

drew as a guide, carefully remove the covering 

from between them using a modeling knife.

When cutting through the covering to remove it, 

cut with only enough pressure to only cut 

through the covering it's self. Cutting into the 

balsa structure may weaken it. This could lead 

to possible failure during flight.

2. Draw a center line onto the horizontal stabilizer.

4. Plug the aileron servo into the receiver and 

center the servo. Install the servo arm onto the 

servo. The servo arm should be perpendicular 

to the servo and point toward the middle of the 

wing.

5. Center the aileron and hold it in place using a 

couple of pieces of masking tape.

6. With the aileron and aileron servo centered, 

carefully place a mark on the aileron pushrod 

wire where it crosses the hole in the servo arm.

7. Using pliers, carefully make a 90 degree bend 

down at the mark made. Cut off the excess wire, 

leaving about 4mm beyond the bend.

6. When you are sure that everything is aligned 

correctly, mix up a generous amount of 30 minute 

epoxy. Apply a thin layer to the top and bottom of 

the stabilizer mounting area and to the stabilizer 

mounting platform sides in the fuselage. Slide the 

stabilizer in place and re-align. Double check all 

of your measurements one more time before the 

epoxy cures. Remove any excess epoxy using a 

paper towel and rubbing alcohol and hold the 

stabilizer in place with T-pins or masking tape.

2. Slide the vertical stabilizer into the slot in the 

mounting platform in the top of the fuselage. Mark 

the shape of the fuselage on the left and right 

sides of the vertical stabilizer using a felt-tip pen.

3.  Now, remove the vertical stabilizer and using a  

modeling knife, carefully cut just inside the marked 

lines and remove the film on both sides of the 

vertical stabilizer. Just as you did with the horizontal 

stabilizer, make sure you only press hard enough to 

cut the film, not the balsa vertical stabilizer.

4. Slide the vertical stabilizer back in place. Using a 

triangle, check to ensure that the vertical stabilizer 

is aligned 90 degree to the horizontal stabilizer.

5. When you are sure that everything is a aligned 

correctly, mix up a generous amount of 30 minute 

epoxy. Apply a thin layer to the slot in the 

mounting platform and to the vertical stabilizer 

mounting area. Apply epoxy to the lower rudder 

hinge. Set the stabilizer in place and  re-align. 

Double check all of your measurements once 

more before the epoxy cures. Remove any 

excess epoxy using a paper towel and rubbing 

alcohol and hold the stabilizer in place with 

T-pins or masking tape. Allow the epoxy to fully 

cure before proceeding.

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. 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.

servo. The servo arm should be perpendicular to 

the servo and point toward the middle of the 

fuselage.

11.  Be sure both elevator halves are flat. Slightly 

adjust the wire joiner if necessary. Center both 

elevator halves and hold them in place using a 

couple of pieces of masking tape.

12. With the elevator halves and elevator servo 

centered, carefully place a mark on the elevator 

pushrod wire where it crosses the hole in the 

servo arm. 

13. Using pliers, carefully make a 90 degree bend up 

at the mark made. Cut off the excess wire, 

leaving about 8mm beyond the bend.

14. Insert the 90 degree bend up through the hole in 

the servo arm, install one nylon snap keeper over 

the wire to secure it to the arm. Install the servo 

arm retaining screw and remove the masking 

tape the elevator halves.

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 100mm 

BACK  FROM  THE  LEADING  EDGE  OF  THE 

WING, AT THE FUSELAGE.

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

pieces of masking tape, place them on the top side 

of the wing 100mm 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 .

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

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. 

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.

100mm

!!!

FLIGHT PREPARATION 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.

6.   Properly balance the propeller.

I/C FLIGHT GUIDELINES

Made in Vietnam

When  ready  to  fly,  first  extend  the 

transmitter aerial.

Operate  the  control  sticks  on  the 

transmitter  and  check  that  the  control 

surfaces  move  freely  and  in  the 

CORRECT directions.

ALWAYS

  land  the  model  INTO  the 

wind, this ensures that the model lands 

at the slowest possible speed.

Switch on the transmitter.

Switch off the transmitter.

Check that the transmitter batteries 

have adequate power.

Switch off the receiver.

Switch on the receiver.

ALWAYS

 take off into the wind.

Check  that  the  wings  are  correctly 

fitted to the fuselage.

If the model does not respond correctly 

to  the  controls,  land  it  as  soon  as 

possible and correct the fault.

Empty the fuel tank after flying, fuel left 

in  the  tank  can  cause  corrosion  and 

lead to engine problems.

I/C FLIGHT WARNINGS

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.

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.

NEVER

 fly near power lines, aerials 

or  other  dangerous  areas  including 

airports, motorways etc.

NEVER

  use  damaged  or  deformed 

propellers or spinners.

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.

ALWAYS 

adjust  the  engine  from 

behind the propeller, and do not allow 

any  part  of  your  body  to  be  in  line 

with the propeller.

 INSTALLING THE WING

1.  Using a modeling knife, remove the covering 

from over the two pre-drilled holes in the 

forward bulkhead that accept the wing hold 

down dowels.

2.  Using a modeling knife, remove the covering 

from over the two pre-drilled wing mounting 

holes in the trailing edge of the wing. Remove 

the covering from over the holes on both the top 

and the bottom of the wing.Glue the nylon plate 

of the screw in place.

3.  Place the wing into the wing saddle to check  

the fit. Temporarily secure the wing in place 

using the two 6mm x 45mm nylon screws.

     Do not over tighten the screws.

 ALIGNING THE BELLY PAN

1.  With the wing securely attached to the fuselage, 

trial fit the belly pan to the bottom of the wing. 

The sides of the belly pan, at both the front and 

the rear, should be flush with the sides of the 

fuselage. 

2.  When satisfied with the fit, hold the belly pan in 

place on the wing using pieces of masking tape.

3.  With the belly pan hold firmly in place and 

aligned properly, use a felt tip pen and outline 

the belly pan onto the wing surface on the two 

outside edges of the belly pan.

4.  Remove the belly pan. Using the lines as a 

guide, use a modeling knife and carefully 

remove about 4mm of the covering from just 

inside the edge of each line. Be careful not to 

cut in to the balsa under the covering.

5. Remove the covering from the rear of the belly pan.

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.

 FINAL ASSEMBLY

PARTS REQUIRED

·  (1) Spinner

·  (2) 3mm x 20mm wood screw.

 INSTALLING THE SPINNER

    Install the spinner back-plate, propeller and 

spinner cone. The spinner cone is held in place 

using two 3mm x 20mm wood screws.

The propeller should not touch any part of the 

spinner cone. If it dose, use a sharp modeling 

knife and carefully trim away the spinner cone 

where the propeller comes in contact with it.

 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.

3. Position the battery pack and receiver behind 

the fuel tank. Use the two light plywood pieces, 

placed over the battery and receiver and glue to 

the fuselage sides to hold the battery  and 

receiver securely in place. Use 15mm triangle 

pieces glued between the fuselage sides and 

the plywood pieces to reinforce the joints.

     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.

 INSTALLING THE BELLY PAN

1. Mix up a generous amount  of 30 minute epoxy. 

Apply a thin layer of epoxy to the bottom edges 

of the belly pan. Carefully set the belly pan back 

in place on the wing and align it as you did 

previously. Remove any excess epoxy using a 

paper towel and rubbing alcohol.

2. Hold the belly pan firmly in place using strips of 

masking tape along the entire gluing surface. 

Allow the epoxy to fully cure before you remove 

the masking tape.

    

Be carefully not to get any epoxy between the 

wing and the fuselage
