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 
STINSON  .46-.55  SCALE  1:8 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
Remove  the  tape  and  separate  the  ailerons  from 
the  wing  and  the  elevators  from  the  stab.  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.

.  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.

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.

4.  With the horizontal stabilizer correctly aligned, 
mark the shape of the fuselage onto the bottom 
and into the top of the horizontal stabilizer 
using 
a water soluble/ non-permanent felt-tip pen.
2.  Draw a center line onto the horizontal stabilizer 
and slide it 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.
13
6. Attach the wing to the fuselage as picture.
8.   When  you  are  sure  that  everything  is  aligned 
correctly,  mix  up  a  generous  amount  of  30 
minute epoxy. Apply a thin layer to the  bottom 
of the stabilizer mounting area and to the stabilizer  
mounting platform sides in the fuselage. Insert 
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.   Test the position of the elevator and adjust it as 
shown.

9.   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.
10.  Repeat  step  1  -  step  5  from  the  installing 
aileron for the installing elevator.

2.  Mount the wing to the fuselage. Using a couple 
of pieces of  masking  tape, place them  on  the 
top  side  of  the  wing  65mm  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 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. 
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.

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 65mm 
BACK  FROM  THE  LEADING  EDGE  OF  THE 
WING,  AT  THE  FUSELAGE.  This  location  is 
recommended  for  initial  test  flying  and 
trimming. BALANCE A PLANE UPSIDE DOWN 
WITH THE FUEL TANK EMPTY.
!
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.
5.  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.
6.  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.

FUEL TANK
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.
    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.
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

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.

    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.

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.
I/C FLIGHT GUIDELINES
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.
