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, YOURSELF & 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, if not assembled and operated correctly, could possibly cause injury to yourself or spectators and damage to property.

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 unfl yable 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 fi rstclass 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 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 exceed 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.

We, as the kit manufacturer, provide 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.

Before starting to build, compare the parts in this model with the Parts List and note any missing parts. Also inspect all parts to make sure they are of acceptable quality. If any parts are missing, broken or defective, or if you have any questions about building or fl ying this airplane, please contact Top Flite at the address or telephone number below. If requesting replacement parts, please provide the full model name (P-40 Warhawk ARF) and the part numbers as listed in the Parts List.

DECISIONS YOU MUST MAKE

This is a partial list of items required to fi nish the P-40 Warhawk ARF that may require planning or decision making before starting to build. Order numbers are provided in parentheses.

BUILDING STAND

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

RADIO EQUIPMENT

A minimum 5-channel radio system with a standard receiver and seven standard size servos with a minimum torque of 50 oz-in [3.6 kg-cm] are required for the control surfaces of the P-40 Warhawk ARF. If installing optional pneumatic retracts, a standard torque servo such as a Futaba S3003 will also be required. One standard torque servo is required for the throttle. A receiver battery pack with a minimum capacity of 1000mAh is recommended.Order numbers are provided below:

Futaba® S9001 Servo Aircraft Coreless BB (FUTM0075)

Futaba S3003 Servo Standard (FUTM0031)

3

Futaba NR4RB Receiver NiCd 4.8V

1000mAh J (FUTM1380)

OR

Hobbico® HydriMax™ 4-Cell 4.8V 2000mAh

NiMH Flat AA Rx U (HCAM6321)

If you have a radio system with enough available channels to mix the fl ap and aileron servos together, then you will need two 16" [406mm] servo extensions to connect the aileron servos directly to the receiver and you will need two 12" [305mm] servo extensions to connect the fl ap servos directly to the receiver:

Futaba Servo Extension 16" J (FUTM3955)

Hobbico Extension 12" Futaba J (HCAM2100)

If you plan to connect the aileron and fl ap servos together using Y-harnesses then you will need two 12" [305mm] servo extensions for the ailerons and two 6" [152mm] servo extensions for the fl ap servos. You will also need two Y-harnesses:

Hobbico Extension 12" Futaba J (HCAM2100)

Hobbico Extension 6" Futaba J (HCAM2000)

Futaba 6" Dual Servo Extension J (FUTM4130)

ENGINE RECOMMENDATIONS

A .60-.91 cu in [10-15cc] two-stroke or .90-1.20 [1520cc] four-stroke engine is required. An O.S. FS-91 Surpass™ II four-stroke engine installation is shown in this manual.

O.S.® FS-91 II Surpass (OSMG0896)

An optional 90° header for the O.S. FS-91 engine is shown in the engine installation section:

O.S. Exhaust Manifold Inside FS-70/FS-91 (OSMG2624)

LANDING GEAR OPTIONS

The P-40 Warhawk ARF includes fi xed wire landing gear. Optional pneumatic retracts can also be

installed. The part number for the pneumatic retract set is provided below:

90° Retract Landing Gear Set (TOPQ7955) Optional Robart parts:

615 100 Degree Rotating Mains (2) (ROBQ1815)

188VR Standard Air Control Kit (ROBQ2302)

190 Air Line Quick Disconnects (ROBQ2395)

Great Planes Wire Axle 2x3/16" (2) (GPMQ4282)

Optional: 650 Straight RoboStrut (ROBQ1700)

SCALE COMPETITION

Though the Top Flite P-40 Warhawk ARF may not have the same level of detail as an “all-out” scratch-built competition model, it is a scale model nonetheless and is therefore eligible to compete in the Fun Scale class in AMA competition (we receive many favorable reports of Top Flite models in scale competition!). To receive the fi ve points for scale documentation, the only proof required that a full size aircraft of this type in your paint/markings scheme did exist is a single sheet such as a kit box cover from a plastic model, a photo, or a profi le painting, etc. If the photo is in black and white other written documentation of color must be provided. Contact the AMA for a rule book with full details.

If you would like photos of the full-size P-40 Warhawk for scale documentation, or if you would like to study the photos to add more scale details, photo packs are available from:

IMPORTANT BUILDING NOTES

There are two types of screws used in this kit:

Sheet Metal Screws are designated by a number and a length. For example #6 x 3/4" [19mm].

This is a number six screw that is 3/4" [19mm] long.

Machine Screws are designated by a number, threads per inch, and a length. For example 4-40 x 3/4" [19mm].

This is a number four screw that is 3/4" [19mm] long with forty threads per inch.

When you see the term test fit in the instructions, it means that you should fi rst position the part on the assembly without using any glue, then slightly modify or custom fit 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.

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.

KIT INSPECTION

Before starting to build, take an inventory of this kit to make sure it is complete, and inspect the parts to make sure they are of acceptable quality. If any parts are missing or are not of acceptable quality, or if you need assistance with assembly, contact Product Support. When reporting defective or missing parts, use the part names exactly as they are written in the Kit Contents list.

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 5.

2. Carefully 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 covering to the wood.

ASSEMBLE THE WING

HINGE THE AILERONS & FLAPS

You can do the right wing first so your work matches the photos the first time through, or you can work on them together.

1. Test fi t the included hinge points into the predrilled pockets in the flap. Press the hinge points into the pockets with the pins in the hinge points aligned parallel with the hinge line on the fl ap. Push the hinge points as far deep as they can fi t into the pockets in the fl ap. Work the hinge up and down in the pocket. Be sure that the hinges move freely inside the pocket. If there is any interference, use a hobby knife to slightly enlarge the pocket as necessary.

2. Fit the fl ap to the wing panel by inserting the other ends of the hinge points into the pockets in the wing trailing edge. Position the fl ap so that there is a 1/16" [1.6mm] gap between the fl ap trailing edge and the edge of the recessed area in the wing as shown. Work the fl ap up and down to ensure smooth movement.

7

3. Remove the fl ap from the wing panel and pull the hinge points from the pockets. Coat the center of each hinge point with petroleum jelly or oil. This will prevent epoxy from sticking to the pivoting portion of the hinges.

Before performing steps 4 and 5, have denatured alcohol and some paper towel pieces ready for epoxy cleanup.

4. Mix up a batch of 30-minute epoxy. Use a toothpick or something similar to coat the insides of the hinge point pockets in the fl ap and the wing panel. Wipe away any excess epoxy from around the pockets using a paper towel dampened with alcohol.

5. Coat one end of each hinge point with epoxy. Insert the hinges into the pockets in the fl ap. Use a clean toothpick to scrape out any excess epoxy that may have squeezed out the pocket.

6. Coat the other end of each hinge point with epoxy.Slowly join the fl ap to the wing while wiping away any excess epoxy that squeezes out of the pockets. When the hinge points are all the way inserted into the wing, defl ect the fl ap downward and check the leading

edge for excess epoxy. Position the fl ap in the recess as was done in step #2. When satisfi ed, set the wing aside and allow the epoxy to cure undisturbed.

1" [25mm]

3/4" [19mm]

Trim the Corners

7. Cut the included 2" x 9" [51mm x 229mm] piece of CA hinge material into 3/4" x 1" [19mm x 25mm] individual hinges. Use a hobby knife or scissors to trim the corners from each hinge to make them easier to insert into the hinge slots.

Drill a 3/32" [2.4mm] hole 1/2" [13mm] deep, in the center of the hinge slot.

Cut the covering away from the slot.

8. Drill a 3/32" [2.4mm] hole 1/2" [13mm] deep in the center of each hinge slot in the wing panel and

8

aileron. Use a sharp hobby knife to carefully cut away the covering just around each hinge slot.

Temporary pin

to keep the hinge

centered.

9. Fit a CA hinge into each hinge slot in the wing panel. If the hinges are diffi cult to install, use a hobby knife to slightly enlarge the slots. Push a pin (T-pins work well for this) through the middle of each hinge to keep them centered.

10. Fit the aileron to the hinges and center it in the opening. Remove the pins from the hinges and position the aileron against the TE of the wing panel. The hinge gap between the aileron and wing should only be wide enough to allow a small line of light through. When satisfi ed, apply 6 drops of thin CA glue to the center of each hinge on both sides. When the CA has dried, gently pull on the aileron to confi rm that it is securely glued in place.

11. Repeat steps 1-10 for the left wing panel.

MOUNT THE SERVOS

Enlarge to 5/64" [2mm]

Cut off unused arms

1. Cut three arms from a four-armed servo arm included with the aileron servo. Enlarge the outer hole of the remaining arm with a 5/64" [2mm] drill bit.

2. Attach a 12" [305mm] servo extension to the aileron servo and secure the connector using tape, heat shrink tubing (not included), or clips specifi cally made for that purpose (Note: If you plan to connect the aileron extensions directly to the receiver without using a Y-harness, you will need servo extensions at least 16" [406mm] in length). Center the servo with your radio system and install the servo arm to the servo perpendicular to the servo case as shown. Be sure to reinstall the servo arm screw into the servo. Install the grommets and eyelets that came packaged with the servo.

3. Center the aileron servo onto the underside of the aileron servo hatch cover. The servo arm should be centered in the opening. Place a 3/4" x 3/4" x 5/16" [19mm x 19mm x 8mm] hardwood servo mounting blocks on each side of the servo against the servo mounting tabs. Use a pencil to mark the positions of the blocks onto the cover.

9

4. Remove the servo from the hatch cover and use epoxy to glue the blocks to the hatch cover.

5. When the epoxy is fully cured, position the servo against the underside of the aileron servo hatch cover between the mounting blocks. Place a piece of paper folded several times between the servo and the hatch cover to space the servo away from the hatch cover. Drill 1/16" [1.6mm] holes through the mounting tabs on the servo case into the blocks. Thread a servo mounting screw (included with the servo) into each hole and back it out. Remove the piece of paper and apply a drop of thin CA to each hole to harden the wood. When the CA has dried, install the servo onto the hatch cover using the hardware supplied with the servo.

6. Use the strings taped inside the aileron servo hatches to pull the servo leads through the wing ribs.

7. Drill a hole into the wing through each hole in the hatch cover using a 1/16" [1.6mm] drill bit. Thread a #2 x 3/8" [9.5mm] self-tapping screw into each hatch mounting hole and back it out. Apply a drop of thin CA to each hole to harden the wood. Install the aileron hatch cover to the wing as shown using four #2 x 3/8" [9.5mm] self-tapping screws and four #2 fl at washers.

8. Mount the fl ap servo and hatch cover in the same way. If using a Y-harness, the fl ap servo requires a 6" [152mm] servo extension. If you plan to connect the fl ap servo directly to the receiver, install a 12" [305mm] extension.
