1/12 scale Combat Corsair ARF is a
great-flying model suitable for sport flying or AMA Combat
Class #2610. Whether you are a competitor or just want a
great-looking and great-flying Corsair, this 1/12 scale
Combat Corsair ARF will become a favorite.

For the latest technical updates or manual corrections to the
Combat Corsair visit the Great Planes web site at
www

.greatplanes.com. Open the “Airplanes” link, then
select the 1/12 scale Combat Corsair ARF. If there is new
technical information or changes to this model a “tech
notice” box will appear in the upper left corner of the page.

We urge you to join the AMA (Academy of Model Aeronautics)
and a local R/C club.The AMA is the governing body of model
aviation and membership is required to fly at AMA clubs.
Though joining the AMA provides many benefits, one of the
primary reasons to join is liability protection. Coverage is not
limited to flying at contests or on the club field. It even applies
to flying at public demonstrations and air shows. Failure to
comply with the Safety Code (excerpts printed in the back of
the manual) may endanger insurance coverage. Additionally,
training programs and instructors are available at AMA club
sites to help you get started the right way. There are over
2,500 AMA chartered clubs across the countr y. Contact the
AMA at the address or toll-free phone number below:

IMPORTANT!!! T w o of the most important things you can do
to preserve the radio controlled aircraft hobby are to avoid
flying near full-scale aircraft and avoid flying near or over
groups of people.

1.Your Combat Corsair should not be considered a toy, but
rather a sophisticated, working model that functions very
much like a full-size airplane. Because of its performance
capabilities, the Combat Corsair, if not assembled and
operated correctly, could possibly cause injury to yourself or
spectators and damage to property.

PRO TECT YOUR MODEL,YOURSELF

& OTHERS...FOLLOW THESE

IMPORTANT SAFETY PRECAUTIONS

2.You must assemble the model according to the instructions.
Do not alter or modify the model, as doing so may result in an
unsafe or unflyable model. In a few cases the instructions may
differ slightly from the photos. In those instances the written
instructions should be considered as correct.

3.You must take time to build straight, true and strong.

4. You must use an R/C radio system that is in first-class
condition and a correctly sized engine and components (fuel
tank, wheels, etc.) throughout the building process.

5.You must correctly install all R/C and other components so
that the model operates correctly on the ground and in the air .

6.You must check the operation of the model before every
flight to insure that all equipment is operating and that the
model has remained structurally sound. Be sure to check
clevises or other connectors often and replace them if they
show any signs of wear or fatigue.

7. If you are not an experienced pilot or have not flown this
type of model before, we recommend that you get the
assistance of an experienced pilot in your R/C club for your
first flights.If you’re not a member of a club, your local hobb y
shop has information about clubs in your area whose
membership includes experienced pilots.

8.While this kit has been flight tested to exceed normal use,
if the plane will be used for extremely high stress flying, such
as racing, or if an engine larger than one in the
recommended range is used, the modeler is responsible for
taking steps to reinforce the high stress points and/or
substituting hardware more suitable for the increased stress .

9. WARNING: The cowl and tail cone included in this kit are
made of fiberglass, the fibers of which may cause eye, skin
and respiratory tract irritation. Never blow into a part to
remove fiberglass dust, as the dust will blow back into your
eyes. Always wear safety goggles, a particle mask and
rubber gloves when grinding, drilling and sanding fiberglass
parts. Vacuum the parts and the work area thoroughly after
working with fiberglass parts.

Remember:Take y our time and follow the instructions to
end up with a well-built model that is straight and true.

ADDITIONAL ITEMS REQUIRED

We, as the kit manuf acturer, provide you with a top quality ,
thoroughly tested kit and instructions, but ultimately the

• When you see the term

test fit

in the instructions, it means
that you should first position the part on the assembly
without using any glue, then slightly modify or

custom fit

the part as necessar y for the best fit.

• Whenever the term

glue

is written you should rely upon
your experience to decide what type of glue to use.When
a specific type of adhesive works best for that step, the
instructions will make a recommendation.

• Whenever just

epoxy

is specified you may use

either

30­minute (or 45-minute) epoxy or6-minute epoxy. When 30­minute epoxy is specified it is highly recommended that
you use only 30-minute (or 45-minute) epo xy, because you
will need the working time and/or the additional strength.

• Photos and sketches are placed before the step they
refer to .Frequently you can study photos in following steps
to get another view of the same parts.

• The stabilizer and wing incidences and engine thrust
angles have been factory-built into this model. However,
some technically-minded modelers may wish to check
these measurements anyway.To view this information visit
the web site at www.greatplanes.com and click on
“Technical Data.” Due to manufacturing tolerances which
will have little or no effect on the way your model will fly,
please expect slight deviations between your model and
the published values.

❏ 1. If you have not done so already, remove the major

parts of the kit from the box and inspect for damage. If any
parts are damaged or missing, contact Product Suppor t at
the address or telephone number listed in the “Kit
Inspection” section on page 5.

❏ 2. 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.

Do the right wing first so your work matc hes the photos
the first time through.You can do one wing at a time, or
work on them together.

❏❏1. Test fit the right aileron to the wing with three

hinges. If the hinges don’t remain centered, stick a pin
through the middle of the hinge to hold it in position.

❏❏2. 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. 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.

❏❏3. Cut the covering from the opening in the bottom of

the wing for the aileron servo. Use an iron to seal the
covering to the edges of the opening.

❏❏4. On the top of the wing cut the covering inside the

opening for the aileron servo wire to pass through. Use an
iron to seal the covering to the edges of the opening.

❏ 5. Repeat steps 1-4 for the left wing panel.

❏❏1. Installing the servos in the wing will require the use

of two 12" [305mm] servo extensions. One Y-harness
connector is required and is used to allow the aileron servos
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.
