discharging the battery to the sot LVC can still cause permanentdamage to the battery.

I you have any urther questions or concerns regarding the handling,charging and/or use o the included Li-Po battery, please contact the HorizonSupport Team at 877-504-0233.

If at any time during the charge or discharge process thebattery begins to balloon or swell, discontinue charging ordischarging immediately. Quickly and saely disconnect thebattery, then place it in a safe, open area away from ammablematerials to observe it or at least 15 minutes. Continuing tocharge or discharge a battery that has begun to balloon or swellcan result in a fre. A battery that has ballooned or swollen evena small amount must be removed rom service completely.

Store the battery at room temperature in a dry area for best results.

When transporting or temporarily storing the battery, the temperaturerange should be rom 40120 degrees Fahrenheit. Do not store thebattery or model in a car or direct sunlight whenever possible. I storedin a hot car, the battery can be damaged or even catch re.

Do not over-discharge the Li-Po ight battery. Discharging thebattery too low can cause damage to the battery resulting inreduced power, duration or ailure o the battery entirely.

Li-Po cells should not be discharged to below 3V each under load. In

the case o the 1S Li-Po battery used or the P-51D, you will not wantto allow the battery to fall to below 3V during ight.

The P-51D receiver unit eatures a sot low voltage cuto (LVC) thatoccurs when the battery reaches 3V under load. When the sot cutooccurs, the ESC of the receiver unit will reduce power to themotor (regardless o the power level you have set with the throttlestick) in order to prevent the voltage o the battery rom droppingbelow 3V. This reduction in power usually requires that you land themodel immediately, at which point you should power down the modeland unplug the ight battery. And while it is possible to power the

model up and to y again after the soft LVC occurs, this is NOTrecommended as continued discharging to the sot LVC will causepermanent damage to the Li-Po battery that results in lost powerand duration when using the battery for subsequent ights, or failureo the battery entirely. Continued attempts to urther discharge thebattery may also result in loss o control while the motor is runningas the voltage o the battery may drop below the minimum operatingvoltage o the receiver and other electronics.

Also, it is not recommended that you y to the soft LVC every timeyou y. Instead, you should be aware of the power level of thebattery/airplane throughout the ight, and if at any time theairplane begins to require more throttle than typical to maintainight, you should land the airplane immediately. Routinely

Battery ChargingIt is important that you only charge the included 1S 3.7V 120mAh 14C Li-PoBattery (PKZ1035) with the included 1S 3.7V DC Li-Po BatteryCharger (PKZ3240) or the previously mentioned E-fite Celectra 4-portCharger (EFLC1004). Attempting to charge the battery using another Li-Pocharger or non-Li-Po compatible charger could result in serious damage.Please amiliarize yoursel thoroughly with the Battery Warnings andGuidelines section beore continuing. Please ollow these steps to charge theLi-Po battery with the included charger:

Remove the cover on the bottom of the charger and install four of theincluded AA batteries, noting proper polarity. Replace the cover ater

the AA batteries are installed.

Slide the battery into the slot on the charger. The end cap of thebattery has been specically designed to allow the battery to be slidinto the slot easily one way (usually with the label on the battery acingoutward) to prevent reverse polarity connection. However, please besure to check or proper alignment and polarity beore proceeding tothe next step.

Gently press the battery and its connector into the charge jack/connector located at the bottom o the slot in the charger. Again,be sure to check or and to achieve proper polarity beore makingthe connection.

After you make the connection successfully, the LED light on thecharger will turn solid red, indicating that charging has begun.

It will take approximately 3040 minutes to charge a fully discharged(not over-discharged) battery. As the battery nears ull charge, the LEDlight will begin to blink. When the battery is ully charged the LED lightwill blink approximately every 20 seconds or will go out entirely.

Note: The Li-Po battery included with your P-51D Mustang will arrivepartially charged. For this reason the initial charge may only take1520 minutes.

Note: You can expect to charge the Li-Po fight battery approximately1520 times beore it will be necessary to replace the AAbatteries in the charger. Replacing the included batteries withalkaline batteries will result in more charge cycles than with theincluded batteries.

Note: I LED remains on or longer than 40 minutes while charging and/or5 seconds ater removing the Li-Po fight battery, please replace theAA batteries in the charger.

Installing the Flight BatteryOnce the Li-Po battery has been ully charged, its ready to be installed in theairplane.

Install the battery in the airplane by placing it into the slot on the bottom othe uselage with the plug acing toward the ront o the airplane.

Note: I you are using E-lite MCX batteries or other batteries without

hook and loop tape, we have included extra hook and loop tapepieces to allow you to use these batteries.

The P-51D RTF comes pre-bound to the included transmitter. I you shouldneed to re-bind your P-51D ollow the simple directions below.

1. To bind your P-51D, rst plug the fight battery into the airplane.

2. When you see the LED on the receiver begin to fash while lookingthrough the opening at the ront o the P-51D under the spinner, pushthe let stick o the transmitter inward into the case (NOT pulling down

on throttle stick) until you hear it click.

3. While pushing the stick in, power on the transmitter, release stick oncethe transmitter is powered on. The transmitter will beep and the LED onthe ace o the transmitter will pulse.

4. Once the transmitter stops beeping it will take a second or two to con-nect with the airplane.

The transmitter is now bound to the airplane. I you encounter any problems,repeat the binding process again, see the troubleshooting guide or call theHorizon Support Team at 1-877-504-0233.

Note: We strongly recommend setting the transmitter on low ratefor the initial ights. To set transmitter to low rate, whilethe transmitter and airplane are powered on, push the rightstick inward until you hear it click. The LED on the transmit-ter face will be ashing steadily indicating that the transmit-ter is in low rate.

When the elevator stick is moved at the elevator should move up.

Move the aileron stick let and right to check aileron roll control. When thestick is pushed to the let, the let aileron should move up and the right aileronshould move down.

You must test the controls prior to the rst fight to ensure none o theservos, linkages or parts were damaged during shipping and handling andthat the controls unction in the correct directions.

Turn the transmitter on rst and lower the throttle stick completely. Then,plug the battery into the battery lead o the receiver unit.

Note: The connectors on the battery and battery lead are keyed to pre-

vent reverse polarity connection. However, i you orce them to-gether in the wrong orientation and with the wrong polarity it is stillpossible to damage the battery and/or receiver unit. To help urtherprevent a reverse polarity connection, one side o the end cap onthe battery and the connector on the battery lead o the receiverunit will have a red dot. The connectors are oriented or a properpolarity connection when the red dots are on the same side.

Move the elevator stick on the transmitter orward and at to checkelevator pitch control. When the stick is pushed orward, the elevator shouldmove down.

Control Test


8/1613 14

With the rudder stick pushed to the let, the rudder should move to the let.

I at any time during the test the controls respond in the opposite direction, itmay be necessary to reverse/change the direction o operation o the fightcontrols. Follow the Reversing Flight Controls section to change the direction

o the various fight controls.

Once youve reconrmed the fight control directions, all controls should beunctioning properly. However, i you continue to encounter any problems withyour P-51D responding properly to the transmitter, do not fy. Call the HorizonSupport Team at 1-877-504-0233.

Digital TrimsThe ParkZone 4-channel 2.4GHz DSM2 transmitter eatures digital trims onall controls to make ne adjustments. Center the control suraces using thetrims. I there is not enough electronic trim available, it may be necessary to

adjust the loops in the control linkages to center the suraces.

Transmitter Dual Rate FunctionThe 4-channel 2.4GHz DSM2 transmitter included with the P-51D eaturesdual rate capability. The deault setting is high rate. To access the low rateunction, simply press IN on the right gimbal. The LED light on thetransmitter ace will begin to blink, alerting you that the transmitter is on lowrate. To return to high rate, simply push in again on the right gimbal.

Note: ParkZone STRONGLY recommends using the LOWRATE setting for conducting the rst ights of your

P-51D Mustang.

With the aileron stick pushed right, the right aileron should move up and thelet aileron should move down.

Move the rudder stick let and right to check yaw control. When the stick ispushed to the right the rudder should also move to the right.

control o the motor, proceed to the next step o the checklist. If the blinking red status LED keeps ashing, you do not have a

positive RF link between the transmitter and receiver. Check to besure that the transmitter has been powered on and that the LEDindicator on the transmitter is glowing solid red. I the transmitter ispowered on and unctioning properly, disconnect the fight battery romthe receiver unit, then reconnect it. Now the receiver unit shouldinitialize and arm properly.

Note: In the event you inadvertently enter Bind Mode, the LED on the

AR6400 will be fashing red continuously. I this occurs, cycle thefight battery while the transmitter is on (i previously bound). I yourreceiver unit will not initialize and arm ater ollowing the guidelinesas listed above, call the Horizon Support Team at 1-877-504-0233.

Once you have placed the airplane in a safe area, free of obstructions,and are clear o the propeller, you can saely begin to power up themodel to check or proper operation o the motor.

Advance the throttle stick upward slowly, just until the propeller beginsto spin. DO NOT attempt to y the airplane at this time. Note the

direction the propeller spins. I viewed rom the ront o the airplane thepropeller will spin counterclockwise. I it is spinning backwards,disconnect the battery and reverse the polarity o the motors inputpower leads.

Note: There is an error in the AR6400 manual or the pin output or thebrushed motor and brushless ESC. I viewed rom the top o thereceiver, the correct pin output or brushed motors is: negative,positive, empty pin. For brushless ESC the pin output is: signal,positive, negative.

Receiver Control Unit Description, Armingand Motor Control Test

The Spektrum AR6400 installed on your P-51D Mustang is a lightweightcombination o main motor electronic speed control, servos and SpektrumDSM2 compatible receiver. The receiver unit is also equipped with a statusindicator LED. Please reer to the instruction manual o the AR6400 or moreinormation on the unique eatures and programming options.

The ollowing checklist contains the steps you must ollow to ensure properarming and operation o the receiver unit, as well as proper motor response:

Each time before you y you should ALWAYS turn the transmitter onbeore connecting the fight battery to the receiver unit. Never connectthe fight battery to the receiver unit beore powering the transmitter onrst. Ater each fight, be sure that you always disconnect the fightbattery rom the receiver unit beore powering the transmitter o.

Note: The only time you should connect the fight battery to the receiver

unit beore powering the transmitter on is when you are bindingthe receiver o the receiver unit to the transmitter. Please see theTransmitter and Receiver Binding section o this manual or moreinormation.

The throttle stick MUST be set in the lowest possible position, and,or most transmitters, the throttle trim must also be set to the lowestpossible position in order or the receiver unit to arm. I this is the rsttest fight, or a test fight ollowing repairs, you should also center therudder, aileron and elevator trims.

When the status LED on the AR6400 becomes solid red, the receiver

unit is initialized and ready or fight. Also, as long as you had thethrottle stick in the idle position and the throttle trim in the lowestposition during the initialization process, the ESC/motor will nowbe armed. Use caution as the propeller will now spin with throttlestick input.

Note: I the status LED o the AR6400 does not become solid red, pleasereview the ollowing:

If after blinking red the status LED becomes solid red, but you haveno control o the motor, you have a positive Radio Frequency (RF) linkbetween the transmitter and receiver, but the throttle stick and throttletrim may not be set to the correct positions. Check to be sure that thethrottle stick is in the lowest possible position, and that the throttle trimis set to the middle or a lower-than-the-middle position. I you now have

Choosing a Flying AreaTo increase the aileron throw, gently pull up on the pushrod to disengage thepushrod rom the outer hole and move to the inner hole on the bellcrank.

Replace the tape on the uselage. The airplane is now set or maximumaileron throw using 100% ATV on the transmitter. To increase rudder andelevator throw, move the pushrods to the inner holes on the control horn onehole at a time and fy the airplane to get used to the increased throw o thecontrol suraces.

Note: I you choose to bind your P-51D Mustang to anothertransmitter, especially one that eatures adjustable dual rate

settings, set them at 70% for rst ights. Dual rates andexpo (i available) can then be tuned to your taste.

When you are ready or your irst light, you will want to select a relativelyopen area, the size o a basketball court or larger, that is ree o peopleand obstructions with calm wind (i lown outdoors). Once you have properlytrimmed your airplane and become amiliar with its handling and capabilities,you will be able to ly in other smaller, less open areas.

Having ollowed the proper receiver initialization and arming procedures,conrmed proper control o the servos and motor, and ound a suitable fyingarea, your P-51D Mustang is ready or fight. Start rst ight using the lowrate settings to become familiar with the ying characteristics beforeincreasing the throw o the control suraces.

Place the P-51D Mustang in position or takeo (acing into the wind i fyingoutdoors). Gradually increase the throttle to to ull, and steer with therudder. Pull back gently with the elevator and climb to check trim. Once the

plane is trimmed, you can begin exploring the fight envelope o the Mustang.

Note: Due to the large propeller on the Mustang, it is possible to hit theprop on the ground while landing. Make sure to fare when landingand try to land as smoothly as possible to minimize hitting the prop.While this does not damage the airplane it is possible to wear downthe tips o the propeller i fying rom an abrasive surace such asconcrete or asphalt.

IN THE UNFORTUNATE EVENT OF A CRASH OR PROPELLER STRIKE,NO MATTER HOW MINOR OR MAJOR, YOU MUST LOWER THE

THROTTLE STICK AND TRIM TO THEIR LOWEST POSSIBLE POSITIONSAS QUICKLY AS POSSIBLE TO PREVENT DAMAGE TO THE ESC OF THERECEIVER UNIT.

Failure to lower the throttle stick and trim to the lowest possible positionsin the event o a crash could result in damage to the ESC in the receiverunit, which may require replacement o the receiver unit.

Note: Crash damage is not covered under the warranty.
