Congratulations on your purchase of one of the Great Planes
Combat Class #2610 Fighters! The P-40 Warha wk ARF is a
great fl ying model suitable for combat fl ying or spor t fl ying.
Accommodations have been provided f or both a glow engine
and a brushless out-runner motor, and optional landing gear
gives the sport fl yer the comfort of paved runway landings.

For the latest technical updates or manual corrections to the
P-40 Warhawk ARF visit the Great Planes web site at www.
greatplanes.com. Open the “Airplanes” link, then select the
P-40 Warhawk 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.

AMA

We urge you to join the AMA (Academy of Model Aeronautics)
and a local R/C club. The AMA is the gov erning body of model
aviation and membership is required to fl y at AMA clubs.
Though joining the AMA provides many benefi ts, one of the
primary reasons to join is liability protection. Coverage is not
limited to fl ying at contests or on the club fi eld. It e v en applies
to fl ying 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!!! Two of the most important things you can do

to preserve the radio controlled aircraft hobby are to avoid
fl ying near full-scale aircraft and avoid fl ying near or over
groups of people.

PROTECT YOUR MODEL, Y OURSELF

& OTHERS....FOLLOW THESE

IMPORTANT SAFETY PRECAUTIONS

1. Your P-40 Warhawk ARF 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 P-40 Warhawk ARF, if not assembled and
operated correctly, could possibly cause injury to yourself or
spectators and damage to property.

We, as the kit manuf acturer , pro vide you with a top quality,
thoroughly tested kit and instructions, but ultimately the
quality and fl yability of your fi nished model depends
on how you build it; therefore, we cannot in any way
guarantee the performance of your completed model,
and no representations are expressed or implied as to the
performance or safety of your completed model.

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

2. Y ou must assemble the model accor ding to the instructions.
Do not alter or modify the model, as doing so may result in an
unsafe or unfl yab le model. In a few cases the instructions may
differ slightly from the photos. In those instances the wr itten
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 fi rst-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
fl ight 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 fl own
this type of model before, we recommend that you get the
assistance of an experienced pilot in your R/C club for
your fi rst fl ights. If you’re not a member of a club, your local
hobby shop has information about clubs in your area whose
membership includes experienced pilots.

8. While this kit has been fl ight tested to e xceed normal use,
if the plane will be used for extremely high-stress fl ying, 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 included in this kit is made of
fi berglass, the fi bers of which may cause eye, skin and
respiratory tract irritation. Never blow into a part to remove
fi berglass 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 fi berglass parts.
V acuum the parts and the work area thoroughly after working
with fi berglass parts.

Building Stand

• The stab 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 inf ormation 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 fl y, please expect slight
deviations between your model and the published values.

ORDERING REPLACEMENT PARTS

Replacement parts for the Great Planes P-40 W arhawk ARF
are available using the order numbers in the Replacement
Parts List that follows. The fastest, most economical
service can be provided by your hobby dealer or mail-order
company.

To locate a hobby dealer, visit the Hobbico web site at
www.hobbico.com. Choose “Where to Buy” at the
bottom of the menu on the left side of the page. Follow the
instructions provided on the page to locate a U.S., Canadian
or International dealer.

A building stand or cradle comes in handy during the build. We
use the Robart Super Stand II (ROBP1402) for all our projects
in R&D and it can be seen in pictures throughout this manual.

IMPORTANT BUILDING NOTES

• When you see the term test fi t in the instructions, it
means that you should fi rst position the part on the assembly

without using any glue, and then slightly modify or custom
fi t the part as necessary for the best fi t.

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

• Whenever just epoxy is specifi ed you may use either
30-minute (or 45-minute) epoxy or 6-minute epoxy. When
30-minute epoxy is specifi ed it is highly recommended that
you use only 30-minute (or 45-minute) epoxy, because you
will need the working time and/or the additional strength.

Parts may also be ordered directly from Hobby Services by
calling [phone], or via facsimile at [phone],

PREPARATIONS

❏ 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 Support at the
address or telephone number listed in the “Kit Inspection”
section on page 7.

❏ 2. Remove the tape and separate all the control surfaces.

Use a covering iron with a covering sock on medium/high
heat to tighten the covering if necessary. Apply pressure over
sheeted areas to thoroughly bond the cov ering to the wood.

❏ ❏ 2. Roughen the portion of the aileron torque rod that

fi ts into the aileron using 220-grit sandpaper. Apply a thin
coating of epoxy to the torque rod and join the aileron to
the wing by fi tting the torque rod into the hole in the LE of
the aileron and the CA hinges into the slots. Wipe away any
excess epoxy with a cloth dampened with denatured alcohol.
Continue on to the next step before the epoxy cures.

BUILD THE WING

Install the Ailerons

❏ ❏ 3. Remove the pins in the hinges. Adjust the ailerons

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 the gap or to slip a piece of paper through. Apply
six drops of thin CA to the top and bottom of each hinge
without using accelerator. After the CA glue has hardened,
confi rm that the ailerons are secure by pulling on them and
defl ecting them up and down.

❏ 4. Repeat steps 2 and 3 for the other wing panel.

❏ 1. T est fi t a CA hinge into each of the hinge slots in the wing

panels and ailerons. If necessary, enlarge the slots with a
hobby knife. When satisfi ed with the fi t, inser t a CA hinge
halfway into each hinge slot in the wing panels. Push a pin
through the middle of each hinge to keep them centered.

❏ 5. Locate the two plywood wing joiners. Mix up a small

amount of epoxy and laminate the two pieces together. Join
the pieces together, being sure the edges are as fl ush as
possible. Use alcohol to wipe away any excess epoxy. Make
note of the top side of the joiner. This should face the top of
the wing panels when installed.

8

8

❏ 6. Trim the covering that overlaps onto the root ribs of

each wing panel. T est fi t the joiner into both wing halves . The
joiner should fi t slightly loose to allow room for epoxy. If the
joiner is too snug, sand the face, top or bottom as necessary
for the proper fi t.

❏ 7. Mix approximately 1/2 oz [15cc] of 30-minute epoxy.

Apply a liberal amount of epoxy into the wing joiner pocket
of each wing, the root rib of each wing and the joiner. Insert
the wing joiner into the right wing panel and then slide the
left panel onto the joiner. Push the tw o halves together fi rmly,
making sure there are no gaps anywhere between the wing
panels. Clean any excess epoxy from the wing surface with
alcohol. Hold the wings together with masking tape and
clamps until the epoxy has completely cured.

❏ 9. Align the wing bolt plate over the holes on the

underside of the wing. There is a shallow perforation on the
uncovered side of the wing bolt plate to allow you to bend
the plate to match the dihedral of the wing. Make note of
the orientation of the wing bolt plate on the wing as it is not
perfectly rectangular. The shor t sides of the wing bolt plate
should be parallel with the inside edges of the ailerons. With
the wing bolt plate centered over the holes, use a fi ne, f elt-tip
pen to trace around the plate onto the wing.

❏ 10. Trim the covering just inside your lines. Wipe away the

lines with alcohol and glue the wing bolt plate to the wing.
Continue the wing bolt holes through the wing bolt plate with
a 1/8" [3.2mm] drill bit. A wood bac ker piece while drilling will
help ensure clean-edged holes in the wing bolt plate.

HOW TO CUT COVERING FROM BALSA

❏ 8. Locate and remove the covering from the wing bolt

holes near the TE of the wing.

Use a soldering iron to cut the covering from the wing. The
tip of the soldering iron doesn’t have to be sharp, but a
fi ne-tip does work best. Allow the iron to heat fully.

Use a straightedge to guide the soldering iron at a rate that
will just melt the covering and not burn into the wood. The
hotter the soldering iron, the faster it must travel to melt a
fi ne cut. Peel off the covering.

Install the Aileron Servo & Pushrods

❏ 1. Install the rubber grommets and eyelets that were

included with the servo. Mount the servo in the aileron serv o
bay and drill a 1/16" [1.6mm] hole through each mounting
hole location. Do not drill all the way through the wing!
The holes should be just deep enough to accommodate
the length of the servo mounting screws. Remove the servo
and install and remove a servo mounting screw (included
with your servo) into each hole. Apply a couple drops of thin
CA into the holes to harden the wood. When the CA has
hardened completely, install the servo into the aileron servo
bay using the servo mounting screws with the servo spline
facing forward.

❏ 4. Screw the aileron torque rod horns onto the threaded

ends of the torque rods fl ush with the ends of the rods.
Position the horns to point forward.

❏ 2. Cut two arms from a four-armed servo arm as shown.

Enlarge the outer holes of the remaining arms using a 5/64”
[2mm] drill bit.

❏ 3. Use your radio system to center the servo. Install the

servo arm perpendicular to the servo case.

❏ 5. Screw a nylon cle vis with a silicone clevis retainer onto

each of the 4-3/4” [120mm] pushrods 20 complete turns.
Connect the clevises to the aileron torque rod horns. P osition
the ailerons in the neutral position with tape or small clamps.
Mark on the pushrods where they cross the outer holes in
the aileron servo arm.

❏ 6. Bend the wires 90 degrees at the marks and cut the

excess wire 1/4" [6mm] beyond the bends. Reattach the

10
