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.

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.

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 

P40  WARHAWK  GP/EP    30/35cc  SCALE  1:4  ¾  

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.

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

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.

TEMPORARY PIN

TO KEEP HINGE

CENTERED

2.  Apply six 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.

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.

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.

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  120mm 

(4.7  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  120mm  (4.7  in)  back  from  the 

leading edge, at the fuselage sides.

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.

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.

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.

INSTALLING THE Fuel 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.

    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.

SECURE The Wing To The Fuselage

    

    Attach the wings to the joiner tube and secure 

the wing panels to the fuselage.

Assemble left and right

sides the same way.

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.

7.  After  the  epoxy  has  fully  cured,  remove  the 

masking tape or T-pins used to hold the stabilizer 

in place and carefully inspect the glue joints. Use 

more epoxy to fill in any gaps that were not filled 

previously and clean up the excess using a paper 

towel and rubbing alcohol.

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.

8.  Installing the elevator using C.A glue as installing

HORIZONTAL STABILIZER INSTALLATION 

1. Using a modeling knife, cut away the covering

    from the fuselage for the stabilizer and remove it.
2. Draw a center line onto the horizontal stabilizer.
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.
