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:
1. 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 Corsair F4U 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.
2. 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.
INSTALLING THE AILERONS
1. Use the modeling knife to cut a strip of covering
from the hinge slots in the wing and aileron.
2. Locate the four CA hinge strip. Snip off the
corners so they go in easier.
3. 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.

6. Tie the string from inside the wing to the end of
the servo wire. Pull the servo wire through the
wing with the string. Tape the servo wire to the
wing to prevent it from falling back into the wing.

4. Remove any pins you may have inserted into
the hinges. Adjust the aileron so there is a
small gap between the LE of the aileron and
the wing. The gap should be small, just enough
to see light through or to slip a piece of paper
through.
5. 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.
INSTALL THE AILERONS SERVOS & PUSHRODS
1. Install the servo in the wing require the use of
one 305mm servo extension for each aileron
servo. One Y-harness connector is required
and is used to allow the aileron servo to plug
into one slot in your receiver. You may have a
computer radio that allows you to plug the
servos into separate slots and then mix them
together through the radio transmitter. If you
choose to mix them with the radio rather than
the Y-harness, refer to the instructions with
your particular brand of radio.
2. Attach the servo extension to the aileron servo.
Secure the connectors together using a large
piece of heat shrink tubing, tape or other
method for securing the connectors together.
3. Turn the wing panel right side up. Using a
modeling knife, remove the covering from over
the precut servo box.
5. Using the string as a guide and pass the string from
the servo opening to the hole in the root of the wing.
Note: A weigh tied to a string can be used first,
then tied to the servo lead to pull it through.

7. Temporarily position the aileron servo into the
servo bay. Drill a 1.6mm hole through the four
mounting holes of the servo, drilling through
the plywood mounting plate in the wing. Install
and remove a servo mounting screw into each
of the four holes. Insert a drop of thin CA into
the holes to harden the wood. After the glue has
cured, install the servo into the servo bay using
the hardware that came with your servo. Center
the servo and install a servo arm as shown.
8. Repeat step # 1 - # 6 to install the second
aileron servo in the opposite wing half.
3. Repeat step # 1 - # 2 to install the control horn
on the second aileron.
INSTALLING THE AILERON LINKAGES
1. Locate the pushrod wire. Slide a silicon clevis
retainer onto a clevis. Screw a M3 nut and a
threaded metal clevis onto the threaded end of
the wire. Tighten the nut against the clevis and
then install the clevis on the aileron control
horn.
INSTALLING THE CONTROL HORNS
1. The aileron has a block wood plate for mounting
the control horn. 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.

2. Drill through the mark you made with a (3mm)
drill bit. Hard the hole with thin CA. Install the
control horn. Remember use thread locking
compound to secure.
Note: The hole on the nylon horn is aligned
with the hinge line and pushrod is aligned with
the servo arm.

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.
4. Center the aileron and hold it in place using a
couple of pieces of masking tape.
5. 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.
6. Using pliers, carefully make a 90 degree bend
down at the mark made. Cut off the excess
wire, leaving about 4mm beyond the bend.
8. Repeat step # 1 - # 7 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.
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.
7. 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.
