TOOLS AND SUPPLIES NEEDED.
PREPARATIONS
• Medium C/A glue.
• 30 minute epoxy.
• 6 minute epoxy.
• Hand or electric drill.
• Assorted drill bits.
• Modeling knife.
• Straight edge ruler.
• 2 bender plier.
• Wire cutters.
• Masking tape.
• Thread lock.
• Paper towels.
• Rubbing alcohol
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.
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.
1
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.
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 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.
TEMPORARY PIN
TO KEEP HINGE
CENTERED
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.
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.
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.

INSTALLING THE CONTROL HORNS
5
1. One aileron control horn in positioned on each
aileron. Using a ruler and a pen, locate and
mark the location of the control horn. It should
be mounted on the bottom side of the aileron at
the leading edge, in line with the aileron
pushrod.
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.
2. Drill two holes through the aileron using the
control horn as a guide and screw the control
horn in place.

1. Attach the pushrod to the outer hole in the
control horn and slide it through the metal
connector.
2. Locate one nylon servo arm, and using wire
cutters, remove all but one of the arms. Using a
2mm drill bit, enlarge the third hole out from the
center of the arm to accommodate the aileron
pushrod wire.
3. 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.

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.
17
7. Test the position of the elevator and adjust it as
shown.
14
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.
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.
15
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.
18
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.

CONTROL THROWS
Remove the covering
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.
Ailerons : 10mm up
Elevator : 8mm up
Rudder : 20mm right
52
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 50mm
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 50mm 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.

FLIGHT PREPARATION PRE FLIGHT CHECK
LATERAL BALANCE
!
1. Completely charge your transmitter and receiver
batteries before your first day of flying.
After you have balanced a plane on the C.G.
You should laterally balance it. Doing this will
help the airplane track straighter.
2. Check every bolt and every glue joint in your
plane to ensure that everything is tight and well
bonded.
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.
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.
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.
6. Properly balance the propeller.
11
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.
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.
12
DO NOT dispose of empty fuel
containers on a fire, this can lead to
an explosion.
I/C FLIGHT GUIDELINES
When ready to fly, first extend the
transmitter aerial.
Switch on the transmitter.
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.
Check that the transmitter batteries
have adequate power.
Switch off the receiver.
Switch on the receiver.
Check that the wings are correctly
fitted to the fuselage.
ALWAYS take off into the wind.
Switch off the transmitter.
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.
