INTRODUCTION
The P-47 Razorback has been recognized as an
excellent modeling subject. The large wing and tail area and lo ng tail m oment ma ke an ide al fl ying airplane
– especially for a warbird! The Top Flite Giant P-47 (with
Razorback option) kit is a very successful model. Now, Top Flite has developed the Giant P-47 Razorback ARF following the same design as the kit. The Giant
P-47 Razorback ARF will get you in the air quickly
with a great looking model, without the sanding and
covering required to build a kit.
For the latest technical updates or manual corrections
to the Giant P-47 Razorback ARF visit the Top Flite
web site at www.top-fl ite.com. Open the “Airplanes”
link, then select the Giant P-47 Razorback 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
If you are not already a member of the AMA, please
join! The AMA is the governing body of model aviation
and membership provides liability insurance coverage,
protects modelers’ rights and interests and is required
to fl y at most R/C sites.

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.
SCALE COMPETITION
Though the Top Flite Giant P-47 Razorback is an ARF
and 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
TABLE OF CONTENTS
3
the Fun Scale class in AMA competition (we receive many favorable reports of Top Flite ARFs in scale competition!). In Fun Scale, the “builder of the model” rule does not apply. To receive the fi ve points for scale documentation, the only proof required that a full size aircraft of this type in this 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.
SAFETY PRECAUTIONS
Protect Your Model, Yourself & Others…
Follow These Important Safety Precautions
1. Your Giant P-47 Razorback 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 Giant P-47 Razorback ARF, 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 good condition, a correctly sized engine, and other components as specifi ed in this instruction manual. All components must be correctly installed so that the model operates correctly on the ground and in the air.
You must check the operation of the model and all
components before every fl i g h t .
5. 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 ab out cl ubs in yo ur area w hose m ember ship i ncl ud es experienced pilots.
6. 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 an d /or su bs ti tuting hardware more sui ta ble for the increased stress.
7. WARNING: The cowl and landing gear covers included in this kit are 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 du st , as the d ust will blow bac k into your eyes. A lway s wear safety goggles, a particle mask and rubber gloves when grinding, drilling and sanding fi berglass parts.
Vacuum the parts and the work area thoroughly after
working with fi berglass parts.
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 t ime a nd f oll ow th e in stru ctio ns to end up with a well-built model that is straight and true.
DECISIONS YOU MUST MAKE
This is a partial list of items required to fi nish the Giant P-47 Razorback ARF that may require planning or decision making before starting to build. Order numbers are provided in parentheses.
ENGINE RECOMMENDATIONS
When considering engines for this model, refer to the engine size recommendations on the cover of the manual. Spark-ignition “gas” engines are most popular with large-scale warbirds such as this. One advantage of a gas engine is economy – gas engines tend to con sume l ess fu el tha n a glow e ngine as wel l.
Additionally, gas engines deposit little exhaust residue
on the model. Among other engines, this model was test fl own with a DLE 61 engine. The DLE 61 provides more than adequate power and fl ies the Giant P-47 Razorback ARF in a scale-like manner.
NOTE: Instructions for mounting every possible engine cannot be incorporated into this manual. Modelers using another engine may refer to the instructions as a guide for mounting their engine in a similar way.

RADIO EQUIPMENT
The radio equipment and number of channels required
to fl y the Top Flite Giant P-47 Razorback ARF depends on the capabilities of your transmitter and how the servos will be connected.
4
The Giant P-47 Razorback ARF requires a servo to
operate the air control valve if using pneumatic retracts, a throttle servo, two fl ap servos, two aileron servos, two elevator servos and a rudder servo. Servos with a minimum of 50 oz-in [3.9kg-cm] of torque are required for operating the elevators, rudder, ailerons and fl aps. We reco mmend that met al geare d servos als o be us ed. Standard servos may be used for the throttle and choke
(the servo operated choke is optional). A micro servo
is required to operate the retract air valve. An optional servo o perate d kill switch may also b e u se d (this is in addition to the manually operated engine kill switch.
A servo operated kill switch is only really necessary
for engines that do not reliably shut off by closing the carburetor, but could also serve as a backup.

Note: The length and quantity of servo extensions and Y-connectors may vary depending on the brand of radio you are using and the radio installation.
The instructions show the two aileron servos
connected with a Y-harness that is plugged into the aileron channel of the receiver. If using a computer radio, the two aileron servos can be plugged into
separate channels of the receiver and mixed together.
The two fl ap servos and the two elevator servos also
use a Y-harness. If plugging the servos into separate channels, follow the instructions included with your radio system on how to mix the channels.
S.BUS SYSTEM
A cutting edge alternative to standard
servo installation!
The innovative Futaba S.Bus system lets you unleash
your fl ight system’s full potential and cut down on cable clutter at the same time. It uses digital serial data communication technology to transmit control signals between your receiver and servos. A single S.Bus cable can carry signals to as many channels as your transmitter can handle. You no longer have to worry about plugging in the wrong servo to the wrong channel, because each servo knows what channel it is dedicated to in advance.
SBD-1 S.Bus Decoder Cables allow the use of existing analog and digital servos, too. By providing today’s pilots with tomorrow’s technology, the Futaba S.Bus system is nothing short of revolutionary.
5
HOW DO YOU INSTALL THE S.BUS SYSTEM?
Installation is actually simplifi ed as compared to your normal system installation. Using the S.Bus system you plug a battery into the SBC-1 channel changing tool, using it to program which channel you want the servo to operate on.
Once programmed the servo will operate as required regardless of which lead it is plugged into. Do this for all of the servos that you
want to operate on the S.Bus system. Install the servos in the airplane and plug them into the S.Bus lead, piggybacking them one onto another. Once completed you plug one lead into the receiver for all of the servos and all of the servos will function as programmed. One lead operates up to 16 servos!
S.Bus leads are available in a number of different lengths to accommodate installation into any size airplane regardless of its complexity.
There are many choices
for the S. Bus receivers; some are tiny 3 port receivers with others being up to 8 channels.
The 8 channel inputs can
be used as you would normally set up a model, allowing you to split the model and have some of it set up as S.Bus while other servos are not using the S. Bus system. Something else to note is that some of the S. Bus servos and receivers are HV or High Voltage, meaning that you could run a straight 2S LiPo for your receiver battery.
Many servo choices are available for use in a wide variety and sizes of aircraft from micros to the largest models.
Your system is not limited to programming only through
the SBC-1 channel changing tool and your transmitter. Utilizing the USB interface, the CIU-2, you can do all of the programming using your PC. Programming with this interface gives more fl exibility and programming options than can be achieved with any other radio system. To utilize standard non S.Bus servos you simply use the S.Bus decoder instead of the S.Bus lead.
This is just the beginning of what this system can do.
Would you like to operate the servos in the wing with a separate battery from the fuselage? With S.Bus you can do that! Run multiple servos – using only a single channel on your transmitter!!

IMPORTANT BUILDING NOTES
Anytime a sheet metal screw is installed in wood, fi rst install the screw, remove the screw and apply a couple of drops of thin CA in the hole to harden the threads. After the CA has cured, reinstall the screw.
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 Giant P-47 Razorback ARF is factory-covered with Top Flite Flat MonoKote fi lm. Should repairs ever be required, MonoKote can be patched with additional MonoKote purchased separately. MonoKote is pa ckage d in si x-fo ot ro lls, b ut som e hobb y shop s also sell it by the foot. If only a small piece of MonoKote is needed for a minor patch, perhaps a fellow modeler would give you some. MonoKote is applied with a model airplane covering iron, but in an emergency a regular iron could be used. A roll of MonoKote includes full instructions for application. Following are the colors used on this model and order numbers for six foot rolls.

ASSEMBLE THE WINGS
HINGE THE AILERONS
Start with the left wing so the assembly matches the photos the fi rst time through.
1. Pull on the ailerons and elevators, making sure
the hinges are secure.
❏ ❏ 2. If necessary, use a covering iron with a
covering sock to go over the wing, fl ap and aileron to remove any wrinkles. The best method to remove the wrinkles is to glide the iron over the covering until the wrinkles disappear, then go over the area again, pushing down on the iron to bond the covering to the wood. If the wrinkles don’t disappear, the balsa in that area might be fl exing inward. If this is happening, don’t press down. Simply let the heat of the iron shrink the covering. If the wrinkles momentarily disappear, then immediately reappear, the iron may be too hot, thus causing air bubbles. Lower the temperature of the iron or use a sharp #11 blade to puncture several holes in the covering, then reheat. The suggested iron temperature is around 360 degrees F.
The P-47 had many attributes that led to its reputation. One of the most important was its durability in combat. Oftentimes the P-47 would bring pilots home with missing cylinders, blown-off wing tips and large portions of tail surfaces missing. The P-47’s internal systems were very durable and well protected.
MOUNT THE AILERON SERVOS
❏ ❏ 1. Install a servo arm on the aileron servo.
Connect the servo to your receiver. Switch on the transmitter and center the servo arm. Position the aileron servo on the aileron servo hatch cover as shown with the servo arm centered in the opening. Set the two 5/16" x 5/8" x 13/16" [7.9 x 15.8 x 20.6mm] hardwood blocks in the embossed servo block locations, checking that they are correct. If not, mark the new location.
❏ ❏ 2. Use 6-minute epoxy to glue the two blocks
to the bottom of the servo hatch over the embossed servo block locations. Thoroughly coat the end of the blocks and allow them to set for a few seconds while the blocks absorb the epoxy. Then, recoat the blocks. Use clamps to hold the blocks to the servo hatch tray.
❏ ❏
3. Once the epoxy has cured, remove the clamps. Place a 1/16" [1.6mm] spacer, such as a piece of cardstock or a piece of paper folded several times, under the servo and between each mounting block.
After the servo is installed the spacer will be removed,
providing adequate spacing for vibration isolation.
❏ ❏ 4. Drill 1/16" [1.6mm] holes through the blocks
for the servo mounting screws. Mount the servo to the blocks with the screws that came with the servo. Remove the servo mounting screws and apply a couple of dr ops of th in CA in each hol e to h arden th e thread s.
Allow the CA to fully harden. Then, reinstall the servos
and remove the spacer.
❏ ❏ 5. Drill 1/16" [1.6mm] holes through the blocks at
the two hole locations on the top of the aileron servo hatch. Install two #2 x 3 /8" [9.5mm] fl at head sheet
9
metal screws to secure the servo mounting blocks to the aileron servo hatch. Use thin CA to harden the screw threads.
❏ ❏ 6. Connect a 24" [610mm] servo extension wire
to the aileron servo. Cut a piece of heat shrink tubing in half and slide it over the servo connections. Shrink the tubing by applying heat to the tubing.
❏ ❏ 7. Use the string in the wing to pull the aileron
servo wire through the wing.
❏ ❏ 8. Place the aileron servo hatch with the servo
in the wing. Be certain that the hatch is positioned correctly as shown. Secure the hatches using six # 2 x 3/8" [9.5mm] fl at head sheet metal screws. Use thin CA to harden the screw threads.
9. Go back to step 1 and install the right aileron
servo following the same procedure.
MOUNT THE RETRACTS
Install the left retract fi rst.
❏ ❏
1. Use a hex wrench to loosen the strut mounting bolt and remove the strut. Slide two aluminum landing gear door mounts onto the strut and reinstall the strut in the strut mount.
❏ ❏ 2. Trim the axle that is included with the Robart
retracts to 1-1/2" [38mm] long. File a fl at spot at the end of the axle. Insert the axle through the included 5" [127mm] wheel and into the retract. Apply a drop of threadlocker to the 10-32 x 3/16" [4.8mm] set screw, included with the retract, and tighten the set screw onto the fl at of the axle. Make sure that the wheel rotates freely.
❏ ❏ 3. Test fi t the retract unit with the wheel into the
wing. Position the retract so the wheel is centered in the wheel well. Adjust the strut position in the retract body as necessary to achieve the correct spacing all the way around the wheel.
❏ ❏
4. Extend the retract. View the wheel from directly above. Adjust the strut so that the wheel is parallel to the root of the wing. Lock the strut in position by applying a drop of threadlocker to the threads and securely tightening the bolts at the top of the strut.
❏ ❏ 5. Double check that the wheel will fully retract
into the wing. Extend the retract to make sure it does not interfere with any part of the wing and that the retract is operating smoothly.
10
❏ ❏ 6. Hold the retract in the wing. Using the mounting
holes as a guide, drill 7/64" [2.8mm] pilot holes into the retract rails. Caution: Do not inadvertently drill into the electric actuator when you get to the middle hole. Mount the retracts with fi ve #6 x 3/4" [19.1mm] sheet metal screws, one in each corner and one in the middle as shown. Use one #6 x 1/2" [12.7mm] sheet metal screw in the hole over the electric actuator.
7. Remove the six screws and retract and apply a
couple of drops of thin CA in the holes. Attach a 12"
Actuator Extension to the retract. If installing pneumatic
retracts, attach the airline to the retracts.
8. Connect the actuator extension or air lines to the string in the retract bay. Guide the extension or air lines through the front of the retract bay, through the fl ap bay and out the hole in the top of the wing. Also pull the aileron servo lead out the hole. Tape the actuator extension or air lines and aileron servo extension to the top of the wing. Remount the retract in the wing.
❏ ❏ 9. Set the retract cover over the retract and drill
a 1/16" [1.6mm] pilot hole using the holes in the cover as a guide.
❏ ❏ 10. Mount the retract cover to the wing with fi ve
#2 x 3/8" [9.5mm] fl at head sheet metal screws.
❏ ❏ 11. Cut two of the landing gear door drill guides
from the back of the manual. Place the drill guides in the rectangle recesses of the landing gear door. Place the landing gear door on a piece of scrap wood and drill a 1/8" [3.2mm] hole through the door at the marked hole location.
❏ ❏ 12. Adjust the position of the two landing gear
door mounts so that they align with the fl ats on the landing gear door when the door is positioned in the landing gear opening.
❏ ❏
13. Install a #4 fl at wash er on 4 -40 x 3/8" [9. 5m m] machine screw. Insert the machine screw through one of the holes in the gear door and thread it into the land ing gear door m ount. Note that i t tigh te ns ag ainst the landing gear strut before it tightens against the gear door. Install the second machine screw to hold th e g ear do or in pos ition. C hec k t o make sure that the gear door is fl ush with the bottom of the wing. 1.5mm thick rectangular plywood spacers have been included to space the gear doors out if needed. Both screws will need to b e s hor tened, a li ttl e a t a time, so th at they tighten against both the landing gear strut and the gear door. Be sure to use threadlocker on the screws.
14. Return to step 1 and mount the retract in the
right wing.
The P-47 was manufactured by Republic Aircraft Corporation, which at one time was named Seversky Aircraft Corporation, started by two fellow Russians, Alexander De Seversky and Alexander Kartveli.

INSTALL THE FLAP SERVOS
❏ ❏
1. Install the fl ap servos following the same procedure used to install the aileron servos. Note that the fl ap servos face the same direction.
❏ ❏
2. Connect a 12" [305mm] servo extension wire to the fl ap servo. Secure the extension to the servo with a piece of heat shrink or electrical tape.
❏ ❏ 3. Route the fl ap servo leads to the root of the
wing and out the hole in the top of the wing.
INSTALL THE AILERON AND FLAP PUSHRODS
Do the left aileron fi rst. Temporarily plug the aileron servo into the receiver. Switch on your transmitter and plug a receiver battery into the receiver. Center the aileron trim.
❏ ❏
1. Slide a silicone clevis retainer over a 4-40 threaded metal clevis. Thread a 4-40 nut followed by the 4-40 metal clevis, threaded 12 turns onto a 4-40 x 12" [305mm] metal pushrod. Attach the clevis to
the aileron servo arm 5/8" [15.9mm] from the center of the arm.
❏ ❏
2. Posi tion t he contr ol hor n s o that it is inl in e with the pushrod and over the plywood mounting plate. The pushrod holes in the control horn should be aligned with the hinge line of the aileron. On the aileron, mark the four mounting holes. Remove the control horn and drill a 5/64" [2mm] pilot hole at each mark. Do not drill completely through the aileron. Attach the control horn using four #4 x 1/2" [12.7mm] sheet metal screws. Use thin CA to harden the holes.
❏ ❏ 3. Install the metal solder clevis in the second
hole from the end of the control horn. Center the aileron servo and aileron. Mark the pushrod where it meets the solder clevis. Remove the pushrod and the solder clevis and cut the pushrod 1/4" [6.4mm] past the mark. Solder the solder clevis to the pushrod using the techniques described in the following Hot Tip.
HOW TO SOLDER
1. Use denatured alcohol or other solvent to thoroughly clean the pushrod. Roughen the end of the pushrod with coarse sandpaper where it is to be soldered.
2. Apply a few drops of soldering fl ux to the end of the pushrod, then use a soldering iron or a torch to heat it. “Tin” the heated area with silver solder by applying the solder to the end. The heat of the pushrod should melt the solder – not the fl ame of the torch or soldering iron – thus allowing the solder to fl ow. The end of the wire should be coated with solder all the way around.
3. Place the clevis on the end of the pushrod. Add another drop of fl ux, then heat and add solder. The same as before, the heat of the parts being soldered should melt the solder, thus allowing it to fl ow. Allow the joint to cool naturally without disturbing. Avoid excess blobs, but make certain the joint is thoroughly soldered. The solder should be shiny, not rough. If necessary, reheat the joint and allow to cool.
4. Immediately after the solder has solidifi ed, but while it is still hot, use a cloth to quickly wipe off the fl ux before it hardens. Important: After the joint cools, coat the joint with oil to prevent rust. Note: Do not use the acid fl ux that comes with silver solder for electrical soldering.
This is what a properly soldered clevis looks like – shiny solder with good flow, no blobs and flux removed.

❏ ❏
4. Slide a silicone clevis retainer over the solder clevis. Reinstall the aileron pushrod with the threaded clevis attached to the control horn.
❏ ❏
5. Assemble and connect the fl ap pushrods following the same procedure. We installed the pushrod in the outer hole of the control horn and the hole 3 /8" [9.5mm] from the center of the servo arm. Note: With the fl ap fully retracted “up”, the servo arm is centered on the servo.
6. Return to step 1 and install the aileron and fl ap
pushrods on the right wing.
The Thunderbolt was a massive airplane, the biggest and heaviest single engine, single-place fi ghter ever built. The engine, the Pratt & Whitney 18 cylinder twin-row radial, developed 2,000 HP and was the most powerful engine at the time. However, in turn, it needed a highly effi cient duct system for its super-charger. The designer, Alexander Kartvile, designed the duct system fi rst, then built the fuselage around it.
JOIN THE WING
Note: Keep the retracts in the retracted (up) position so
they do not extend and retract as you handle the wing.
1. Clean the aluminum wing joiner with denatured
alcohol to remove any possible contaminant.
2. Gather everything required for gluing the wing
joiner and wing together including 30-minute epoxy, mixing sticks, epoxy brush, clamps, #64 rubberbands,
12" [305mm] long dowel or wire, denatured alcohol and
small paper towel squares. Mix up a 1/2" oz. [14.7cc] of 30-minute epoxy. Apply a generous amount of epoxy to one side of each of the plywood wing joiners. Sandwich the aluminum wing joiner between the two plywood wing joiners. Hold the joiner together with clamps. Use a paper towel dampened with denatured alcohol to wipe off any excess epoxy around the edges.
3. Use 6-minute epoxy to glue the two 3/8" [9.5mm] diameter forward wing dowels in the leading edge of the wing. The wing dowels should protrude approximately
1/2" [12.7mm] from the wing. Also glue the 1/4" [6.4mm]
aft root rib guide dowel in the left wing half. Clean off any excess epoxy before it cures.
4. Once the epoxy has cured, remove the clamps
from the wing joiner and sand off any excess epoxy you may have missed. Test fi t the wing joiner in each wing half makin g sur e that both wings halves fi t t ogeth er at the root without any gap. Trial fi t clamping the wing
