INTRODUCTION
Following the great success of the .60-sized Top Flite P-51 Mustang kit comes the same beautiful model in ARF form! The sky is the limit for the amount of additional detail that could be added during the building process to make the P-51 Mustang ARF a model even the most serious scale-minded builder could appreciate. The model assembles in as little as 15 to 20 hours with time-consuming painting tasks expertly complete out of the box.
For the latest technical updates or manual corrections to the P-51 Mustang ARF visit the Top Flite web site at www.top-flite.com. Open the “Airplanes” link, then select the P-51 Mustang 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 governing 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 even 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 country. Contact the AMA at the address or toll-free phone number below:
Academy of Model Aeronautics
5151 East Memorial Drive Muncie, IN 47302-9252
Tele. (800) 435-9262 Fax (765) 741-0057 Or via the Internet at:
http://www.modelaircraft.org
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-51 Mustang 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-51 Mustang 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 fi rst-class condition, and a correctly sized engine and components (servos, servo extension, etc.) throughout the building process.
2
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.
DECISIONS YOU MUST MAKE
This is a partial list of items required to fi nish the P-51 Mustang 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 6-channel radio system such as a Futaba® 6EXAS with a standard receiver and six standard size servos with a minimum torque of 44 oz-in [3.2 kg-cm] are required for the control surfaces of the P-51 Mustang ARF. The included mechanical retracts require a 180° retract servo. If you will be installing optional pneumatic retracts, a micro servo will be required to operate the air valve. One standard torque servo such as an S3003 is required for the throttle. Two 24" [610mm] servo extensions (aileron servos) and two Y- harnesses (aileron and flap servos) are also required. A receiver battery pack with a minimum capacity of 1000mAh is recommended. Order numbers are provided as follows:
Futaba S9001 Servo Aircraft Coreless BB (FUTM0075)
Futaba S136G Compact Retract Servo (FUTM0670)
Futaba S3003 Servo Standard (FUTM0031)
Hobbico® Extension 24" Futaba J (HCAM2200)
Futaba 6" Dual Servo Extension J (FUTM4130)
Futaba NR4RB Receiver NiCd 4.8V 1000mAh (FUTM1380)
Optional:
Futaba S3115 Micro Precision Servo (FUTM0415)
ENGINE RECOMMENDATIONS
A .60 to .91 cu in [10 to 15cc] two-stroke or .90 to 1.20 [15 to 20cc] 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 Surpass II (OSMG0896)
LANDING GEAR OPTIONS
The P-51 Mustang ARF includes mechanical retracts. Optional pneumatic retracts can also be installed. Part numbers are provided below.
Robart® 605HD 90° main landing gear w/3/16" wire (ROBQ0005)
Robart 188VR standard air control kit (ROBQ2302)
Robart 190 air line quick disconnects (ROBQ2395)
SCALE COMPETITION
Though the Top Flite P-51 Mustang 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 five 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 profile painting, etc. If the photo is in black and white
3
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-51D Mustang 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.
4
When a specific 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.

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 tabs on 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 TE. Push the fl ap up against the wing so that the fl ap LE and the wing TE edge touch. If the two surfaces cannot touch, carefully deepen the hinge point pockets in the wing panel with a 3/16" [4.8mm] drill bit as necessary. When satisfi ed, defl ect the fl ap down at least 1-1/4" [32mm] which will cause the pivot pins in the hinge points to align themselves in the center of the fl ap LE radius. Work the fl ap up and down to ensure smooth movement.
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
7
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 up to the tabs. Insert the hinges into the pockets in the flap. Use a clean toothpick to scrape out any excess epoxy that may have squeezed out of the pocket.
6. Coat the other end of each hinge point up to LE of the fl ap. Slowly join the fl ap to the wing while wiping away any excess epoxy that squeezes out of the pockets. When the fl ap is all the way against the wing panel, defl ect it downward and check the LE for excess epoxy. Pull the fl ap away from the wing approximately 1/64" [0.4mm] so that the LE does not bind against the wing TE when the fl ap is defl ected. When satisfi ed, set the wing aside and allow the epoxy to cure undisturbed.
7. Cut the included 2" x 9" [51 x 229mm] piece of CA hinge material into 3/4" x 1" [19 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.
8. Drill a 3/32" [2.4mm] hole 1/2" [13mm] deep in the center of each hinge slot in the wing panel and aileron. Use a sharp hobby knife to carefully cut away the covering just around each hinge slot.
9. Fit a CA hinge into each hinge slot in the wing panel. If the hinges are diffi cult to install, use a hobby
8
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 between the wing tip and the fl ap. 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
Before completing this section, confirm that the servos that you will be using will properly fit between the servo mounting block locations on the aileron and flap servo hatch covers. Make adjustments as necessary for your brand servos. The block locations shown in this section will fit a standard size Futaba brand servo.
1. Use epoxy to glue the 5/16" x 3/4" x 3/4" [8 x 19 x 19mm] hardwood servo mounting blocks to the inside of the aileron servo hatch cover. Be sure that the blocks are aligned over the rectangles with the grain direction perpendicular to the covers as shown. Allow the epoxy to cure undisturbed.
2. 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.
3. Attach a 24" [610mm] servo extension to each aileron servo and secure the connector using tape or heat shrink tubing (not included). Center the servos 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.
4. Place a piece of paper folded several times, between the servo and the servo hatch cover to raise the servo off of the servo hatch. Position the servo against the underside of the aileron servo hatch cover between the mounting blocks. 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.

5. Use the string taped inside the aileron servo hatch to pull the servo lead through the wing ribs.
6.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.
7. Mount the fl ap servo and hatch cover in the same way. The fl ap servo does not require a servo lead extension.
8. Repeat steps 1 to 7 for the left wing panel. Make note that the fl ap servo arm will be mounted on the root rib side of the left wing panel so that when the fl ap servos are joined together using a Y-harness, they will both move in the same direction.
INSTALL THE AILERON & FLAP PUSHRODS
1. Thread a 2-56 nut and a metal clevis 15 complete turns onto a 4" [152mm] pushrod. Slide a silicone clevis retainer onto the clevis and connect the clevis to the outer hole of a nylon control horn.
2. Position the control horn over the plywood plate in the aileron (if you cannot see it, hold the aileron at a shallow angle in good lighting or use a small pin to puncture the covering) using the position of the servo arm as a guide. Align the holes in the control horn directly over the aileron hinge line and mark the location of the control horn mounting holes.
3. At the marks, drill 1/16" [1.6mm] holes through the plywood plate. Do not drill all the way through the aileron! Thread a #2 x 3/8" [9.5mm] self-tapping
