CHAPTER 4: BATTERY CHARGING

TRANSMITTER/RECEIVER 4ANote: It is imperative that you fully

charge both the transmitter and thereceiver battery packs prior to eachtrip to the field. To do so, leave thecharger and batteries hooked upovernight (16 hours). The firstcharge should be approximately20–24 hours in order to fully chargeboth battery packs to peak capacity.

The charger supplied with this system isdesigned to recharge your batteries at arate of 50mAh for the transmitter and120mAh for the receiver battery pack.

Transmitter OnlyThe center pin on all JR® Remote ControlSystems is negative. Therefore, thecenter pin on all JR chargers is negative,not positive. This is different from manyother manufacturers' chargers and radiosystems. Beware of improperconnections based on "color-coded" wireleads, asthey do not apply in this instance. Youmust make sure that the center pin ofyour JR transmitter is always connectedto the negative voltage for correctpolarity hookup.

Important: Please note that thecharging polarity of the transmitterand receiver are different.

CHARGER PIGTAIL FOR TRANSMITTER

CHARGER PIGTAIL FOR RECEIVER

CHARGER 4BThe pilot lamps should always be onduring the charging operation. If not,check to make sure that both thetransmitter and receiver are switched off.

Do not use the charger for equipmentother than JR. The charging plug polaritymay not be the same. Equipmentdamage can result.

Do not use other manufacturers' after-market accessories that plug into thetransmitter's charging jack if you areunsure of compatibility issues with yourradio. Seek expert advice to avoidpossible damage.

During the charging operation, thecharger's temperature is slightlyelevated. This is normal.

4C ADVANCED DIGITAL TRIMS

The XP6102's digital trims feature theDirect Access display function. While atthe Normal display screen, if a trim leveris moved, the screen will automaticallychange to display the graphic position forthe trim being adjusted. The XP6102'sAileron, Elevator, Throttle and Ruddertrim levers feature an audible center trimbeep. This is helpful in determining thetrim levers center position during flight.

Please also note that unlike conventionalmechanical trim levers, when the X-6102transmitter is in the off position, nochanges can be made to the trim valuesduring transportation.

1G DIRECT SERVO CONTROL (DSC)

For proper DSC hook-up andoperation:1. Leave the transmitter power switch

in the Off position. The transmitter willnot transmit any radio frequency (RF)in this position.

2. Plug the (supplied) DSC cord into theDSC port in the rear of the transmitter.

3. The encoder section of the transmitterwill now be operational and the LCDdisplay will be lit.

4. Plug the other end of the DSC Cordinto the receiver charge receptacle.Turn the switch harness to the Onposition.

Note: When you install the chargingjack, be sure to hook the chargingjack receptacle securely into theswitch harness charge cord.

Why you should use the DSCfunction:1. The DSC enables you to check the

control surfaces of your aircraft withoutdrawing the fully operational 200mAhfrom your transmitter battery pack.Instead, you will only draw

approximately 70mAh when using theDSC function.

2. The DSC function allows you to makefinal adjustments to your airplanewithout transmitting any radio signals.Therefore, if another pilot is flying onyour frequency, you can still adjust youraircraft and not interfere with the otherpilot’s aircraft.

Note: This function is for bench-checking your airplane only.

NECK STRAP ATTACHMENT 1HAn eyelet is provided on the face of theXP6102 transmitter that allows you toconnect a Neck Strap (JRPA023). This

hook has been positioned so that yourtransmitter has the best possible balancewhen you use the neck strap.


BASE LOADED ANTENNA 1IAn optional base-loaded antenna isavailable for use with the XP6102transmitter. It is considerably shorter thanthe standard antenna. However, the baseloaded antenna cannot be collapsed forstorage inside the transmitter. You mustalso use an adapter (JRPA156) to attach

the antenna to your XP6102. The BaseLoaded Antenna (JRPA155) is made of aflexible coil and is covered with a softplastic material. Your range will not beaffected when using the base loadedantenna.

FREQUENCY NOTES/AIRCRAFT ONLY FREQUENCIES 1JThe XP6102 transmitter employs a plug-in crystal for the transmitter that is gluedin place at the time of shipment. Per FCCregulation, the transmitter crystal shouldonly be changed by a certifiedtechnician. Changing of the transmittercrystal by a non-authorized techniciancould result in a violation of FCC rules.

The XP6102 can transmit in eitherPulse Code Modulation (PCM) orPulse Position Modulation (PPM,commonly referred to as FM).

Be certain to observe the followingguidelines:Do not operate your transmitter whenanother transmitter is using the samefrequency, regardless of whetherthe second transmitter is PCM, PPM(FM) or AM. You can never operatetwo transmitters on the samefrequency simultaneously withoutcausing interference.

Aircraft-Only FrequenciesJR® Transmitters and receivers areavailable in 72MHz frequencies inthe United States for use withmodel aircraft. Employing 72MHzfrequencies does not require a specialoperator’s license from the FederalCommunications Commission (FCC).

* A chart for all available frequencies islocated on page 87 of this manual.

2A INSTALLATION REQUIREMENTS

It is extremely important that your radiosystem be correctly installed in yourmodel. Here are a few suggestions forinstalling your JR® equipment:

1. Wrap the receiver in protective foamrubber that is no less than 3/8 inchthick. Secure the foam to the receiverwith #64 rubber bands. This protectsthe receiver in the event of a crashor a very hard landing.

2. The servos should be mounted usingrubber grommets and brass eyelets toisolate them from vibration. Do notover-tighten the mounting screws; thiswill negate the vibration absorptioneffect of the rubber grommets. Thefollowing diagram will assist you inproperly mounting your servo.The brass eyelets are pushed from the

bottom up in the rubber grommets.When the servo screw is tightenedsecurely, it provides the proper securityas well as the proper vibration isolationfor your servo.

3. The servos must be able to movefreely over their entire range of travel.Make sure that the control linkages donot bind or impede the movement ofany of the servos.

4. Mount all switches away from theengine exhaust and away from anyhigh vibration areas. Make sure theswitch operates freely and is able tooperate over its full travel.

5. Mount the receiver antenna firmly tothe airplane to ensure that it will notbecome entangled in the propeller orcontrol surfaces.

Definition of Wing Types

Normal- This is used with aircraft withone servo operating both ailerons. Thismode is the default setting and is activewhen the Flaperon, Elevon and V-Tailmodes are off.

Flaperon- This mode is used when twoservos are used to operated the ailerons.Flaperons allow each aileron to beindependently adjusted. In addition, theycan be programmed to move in the samedirection for use as flaps or spoilers

Elevon- This mode is used for sometypes of delta wing aircraft where thecontrol surfaces function as both aileronsand elevators.

V-Tail- Used for V-tailed airplanes.

Note: Some function will be unavailablewhen certain functions are active.With Flaperon active, Elevon will beunavailable. With Elevon active, bothFlaperon and V-Tail will beunavailable. Finally, with V-Tailactive, Elevon will be unavailable.


Flaperon Wing Type Selection

Flaperons allow you to use the existingailerons as flaps. The ailerons can beraised or lowered in unison as flaps, yet

still remain fully operational as theailerons of your RC airplane.

Accessing and Utilizing the Flaperon Wing Type Selection

1. While the Down and Select buttonsare pressed, move the power switchto the On position to access theSystem mode.

2. Press either the Up or Down keys untilWING TYPE appears in the upper areaof the LCD.

3. Press either the (+) or (-) key toturn on the Flaperon (FLPR)Wing Type Selection.

Note: For Flaperon, one servo must beused for each aileron controlsurface.

4. Plug the left wing aileron servo intothe Auxiliary 1 (AUX 1) port of yourJR receiver. Connect the right aileronservo into the aileron port (AILE) ofyour receiver.

5. Check to make sure that the wingservos move in the proper direction. Fora right turn, the right aileron shouldraise while the left aileron lowerssimultaneously. For a left turn, theopposite is true; the left aileron shouldrise while the right aileron drops. Ifyour servos are not moving in thedirection just described, use theServo Reversing function to reverse thetravel direction of the servo(s) that aremoving improperly. Refer to the ServoReversing section for information onhow to reverse the travel direction.

Note: Each servo's travel direction isadjusted individually through theServo Reversing function.

Once the servos achieve their propertravel direction, adjust their travelamount, dual rates, sub-trim andaileron differential.

Note: The applicable channel's left orright travel adjustment may be madeindividually by accessing the TravelAdjust function. Refer to the TravelAdjust section of this manual formore information. The fineadjustments of your aileron controlsshould be made in the Dual-Ratefunction. Refer to the Dual-Ratesection for information on how todo so. You can also adjust theneutral point of your aileron servosindividually through the use ofthe Sub-Trim function. Refer to theSub-Trim section of this manualfor more information.

6. The flap lever located on the leftface of the transmitter controls theaileron movements as flaps. To turnoff flaps go to the Flap Systemfunction on page 39 and reducethe flap value to 0%.

Note: Differential is offered for theFlaperon function of your XP6102.For more information, pleaserefer to the Differential section ofthis manual.

Elevon Type Selection

Elevon Wing Mixing is available as anoption with your XP6102. This style ofaircraft also employs two wing servos.However, there is not an elevatorpresent. Instead, an elevator stick inputcauses the two wing servos to function inconjunction with one another to changethe pitch movement of the aircraft. Also,when an aileron control is given, the twowing servos move in opposition to oneanother to function as ailerons.

Accessing and Utilizing the Elevon Type Selection

1. While the Down and Select keysare pressed, move the power switchto the On position to access theSystem mode.

2. Press either the Up or Down key untilWING TYPE appears on the LCD.

3. Press the Select key to select theElevon function.

4. Press either the (+) or (-) key to turnon the Elevon Wing Type function.

Note: The Elevon function requires oneservo for each elevon, i.e. a separateservo for each wing half.

5. Plug the left elevon servo to theaileron (AILE) of your JR receiver.Connect the right elevon servo into theelevator (ELEV) port of your receiver.

6.Check to make sure the servos movein the proper direction. When an inputis given from the elevator stick, theyshould move in unison to achieve theproper up/down elevator command. Ifyour servos do not move as describedabove, use the Servo Reversingfunction to reverse the travel direction.

Note: Each servo's direction is adjustedindividually through the ServoReversing function. For moreinformation, refer to the ServoReversing section in this manual.

7. Once the servos direction has beenset, adjust their travel direction, travelvolume, dual rates, sub-trim andaileron differential.

Note: The applicable channel's left orright, up or down travel adjustmentscan be made individually. Refer tothe Travel Adjust section in thismanual for more information.

TRAINER FUNCTION 5EThe XP6102 offers a programmabletrainer function with three trainer options:

Normal Mode - In this mode thetransmitter acts as a conventional buddy-box system. The transmitter can be usedas a slave or as a master: however inthis mode, the reversing switches andtrims must be adjusted so the slavetransmitter matches the mastertransmitter. In normal mode, when thetrainer switch is activated, the studenthas control of all functions and switches.

Pilot Link - When Pilot Link mode isused with the master transmitter, it allowsthe slave transmitter to be adjusted tofactory defaults. The slave transmittercan simply be programmed in a modelmemory not being used and reset tofactory defaults, thus preventing the needto synchronize the trims and reversingswitches on the slave transmitter.

Also, when Pilot Link is used, the studentonly has control of the 4 basic channels(throttle, aileron, elevator, rudder) whilethe trainer (master) retains control of allother functions like gear, dual rate,programmed mixes, etc. This allows apilot to have a test flight on a morecomplex airplane without having toremember complex switch positions.

Pilot Link + Slave - This mode is usedonly when the XP6102 is being used asa slave transmitter and the other Mastertransmitter has a Pilot Link programactive. By selecting Pilot Link + Slave thetransmitter is automatically in the correctprogramming mode to work as a slave inconjunction with another Pilot Linkequipped transmitter.

6B DUAL RATES AND EXPONENTIAL

Dual rates are available for the aileron,elevator and rudder channels of yourR/C aircraft. The combined Dual RateFunction is discussed on Page 24 -Switch Select. Dual rates may be definedas the ability to vary the travel or throwrate of a servo from a switch. Due to thediffering travel rates, you will find that thesensitivity of the control either increasesor decreases accordingly. A higher rate,or travel, yields a higher overallsensitivity. You may find it easier to thinkof the Dual-Rate function as double-ratesor half-rates.

Exponential reduces the sensitivity in themiddle portion of stick movement, whilestill allowing full travel at the end of thestick movement. The end result (travel)remains the same, although exponentialchanges the rate at which it achievesthis travel. The adjustable range is from0–100%. Zero percent (0%) is linearstick control, meaning the responserate is equal throughout the stick control.100% is full exponential. The larger theexponential value, the less servo actionor sensitivity you will notice around theneutral setting.


Accessing the Dual–Rate and Exponential Function

1. Place the transmitter power switch inthe On position.

2. Access the Function mode bypressing the Down and Selectkeys simultaneously.

3. Press either the Up or Down key untilD/R & EXP appears in the upper leftcorner of the LCD.

6J PROGRAMMABLE MIXING (1-4)

The XP6102 offers four programmablemixes to be used for any number ofdifferent purposes. This function allowsmixing any one channel to any otherchannel. This mix can remain on at alltimes or be switched on and off in flightusing a number of different switches.

Mix numbers 1-3 are of the standardvariety, in that the digital trim for themaster channel only affect the masterchannel, and not the slave channel. Mixnumber 4 is of the "Trim Include" variety.This mix is used any time the mixrequires the slave channels trim positionto be varied when the master channelsdigital trim position is varied. An examplefor this type of mix would be when dualelevator or dual aileron servos are usedand connected to two separate channelsof the system, rather than using a singlechannel with a Y-harness.

Each channel of this radio is identified byan abbreviated name. The chart belowindicates the channel and itscorresponding abbreviation. The channelname appearing first is known as the"master channel" or the channel to whichyou want to mix. The second number isknown as the "slave channel" or thechannel that is being mixed into themaster channel. For example, AIL ➔RUD would indicate aileron-to-ruddermixing. Each time the aileron stick ismoved, the aileron will deflect, and therudder will automatically move in thedirection and to the value input.

Mixing is proportional, so small inputsof the master channel will producesmall outputs of the slave channel. Eachprogrammable mix has a mixing "offset."The purpose of the mixing offset isto re-define the neutral position of theslave channel.

7G DIRECT SERVO CONTROL (DSC)

For proper DSC hook-up andoperation:1. Leave the transmitter power switch

in the Off position. The transmitterwill not transmit any radio frequency(RF) in this position.

2. Plug the (supplied) DSC cord into theDSC port in the rear of the transmitter.

3. The encoder section of the transmitterwill now be operational and the LCDdisplay will be lit.

4. Plug the other end of the DSC Cordinto the receiver charge receptacle.Turn the switch harness to the Onposition.

Note: When you install the chargingjack, be sure to hook the chargingjack receptacle securely into theswitch harness charge cord.

Why you should use the DSCfunction:1. The DSC enables you to check the

control surfaces of your aircraft withoutdrawing the fully operational 200mAhfrom your transmitter battery pack.Instead, you will only draw

approximately 70mAh when using theDSC function.

2. The DSC function allows you to makefinal adjustments to your airplanewithout transmitting any radio signals.Therefore, if another pilot is flying onyour frequency, you can still adjust youraircraft and not interfere with the otherpilot’s aircraft.

Note: This function is for bench-checking your helicopter only.

NECK STRAP ATTACHMENT 7HAn eyelet is provided on the face of theXP6102 transmitter that allows you toconnect a Neck Strap (JRPA023). This

hook has been positioned so that yourtransmitter has the best possible balancewhen you use the neck strap.

BASE LOADED ANTENNA 7IAn optional base-loaded antenna isavailable for use with the XP6102transmitter. It is considerably shorter thanthe standard antenna. However, the baseloaded antenna cannot be collapsed forstorage in side of the transmitter. Youmust also use an adapter (JRPA156) to

attach the antenna to your XP6102. TheBase Loaded Antenna (JRPA155) ismade of a flexible coil and is coveredwith a soft plastic material. Your rangewill not be affected when using thebase-loaded antenna.

FREQUENCY NOTES/AIRCRAFT ONLY FREQUENCIES 7JThe XP6102 transmitter employs aplug-in crystal for the transmitter that isglued in place at the time of shipment.Per FCC regulation, the transmittercrystal should only be changed by acertified technician. Changing of thetransmitter crystal by a non-authorizedtechnician could result in a violation ofFCC rules.

The XP6102 can transmit in eitherPulse Code Modulation (PCM) orPulse Position Modulation (PPM,commonly referred to as FM).

Be certain to observe the followingguidelines:Do not operate your transmitterwhen another transmitter is usingthe same frequency, regardless ofwhether the second transmitter is PCM,PPM (FM) or AM. You can never operatetwo transmitters on the samefrequency simultaneously withoutcausing interference.

Aircraft-Only FrequenciesJR® Transmitters and receivers areavailable in 72MHz frequencies inthe United States for use with modelaircraft. Employing 72MHz frequenciesdoes not require a special operator’slicense from the FederalCommunications Commission (FCC).

* A chart for all available frequencies islocated on page 87 of this manual.


8A INSTALLATION REQUIREMENTS

It is extremely important that your radiosystem be correctly installed in yourmodel. Here are a few suggestionsinstalling your JR® equipment:

1. Wrap the receiver in protective foamrubber that is no less than 3/8 inchthick. Secure the foam to the receiverwith #64 rubber bands. This protectsthe receiver in the event of a crash or avery hard landing.

2. The servos should be mounted usingrubber grommets and brass eyelets toisolate them from vibration. Do notover-tighten the mounting screws; thiswill negate the vibration absorptioneffect of the rubber grommets. Thefollowing diagram will assist you inproperly mounting your servo.

The brass eyelets are pushed from thebottom up in the rubber grommets.When the servo screw is tightenedsecurely, it provides the proper securityas well as the proper vibration isolationfor your servo.

3. The servos must be able to movefreely over their entire range of travel.Make sure that the control linkages donot bind or impede the movement ofany of the servos.

4. Mount all switches away from theengine exhaust and away from anyhigh vibration areas. Make sure theswitch operates freely and is able tooperate over its full travel.

5. Mount the receiver antenna firmly tothe airplane to ensure that it will notbecome entangled in the propeller orcontrol surfaces.

TRAINER FUNCTION 11FThe XP6102 offers a programmabletrainer function with three trainer options:

Normal mode - In this mode thetransmitter acts as a conventional buddy-box system. The transmitter can be usedas a slave or as a master: however inthis mode, the reversing switches andtrims must be adjusted so the slavetransmitter matches the mastertransmitter. In normal mode, when thetrainer switch is activated, the studenthas control of all functions and switches.

Pilot Link - When pilot link mode is usedwith the master transmitter, it allows theslave transmitter to be adjusted to factorydefaults. The slave transmitter can simplybe programmed in a model memory notbeing used and reset to factory defaults,thus preventing the need to synchronizethe trims and reversing switches on theslave transmitter.

Also, when Pilot Link is used, the studentonly has control of the 4 basic channels(throttle, aileron, elevator, rudder) whilethe trainer (master) retains control of allother functions like gear, dual rate,programmed mixes, etc. This allows apilot to have a test flight on a morecomplex airplane without having toremember complex switch positions.

Pilot Link + Slave - This mode is usedonly when the XP6102 is being used asa slave transmitter and the other Mastertransmitter has a Pilot Link programactive. By selecting Pilot Link + Slave thetransmitter is automatically in the correctprogramming mode to work as a slave inconjunction with another Pilot Linkequipped transmitter.

Dual rates are available for the aileron,elevator and rudder channels of yourRC aircraft. The combined Dual RateFunction is discussed on Page 24 -Switch Select. Dual rates may bedefined as the ability to vary the travel orthrow rate of a servo from a switch. Dueto the differing travel rates, you will findthat the sensitivity of the control eitherincreases or decreases accordingly. Ahigher rate, or travel, yields a higheroverall sensitivity. You may find it easierto think of the Dual-Rate function asdouble-rates or half-rates.

Exponential reduces the sensitivity in themiddle portion of stick movement, whilestill allowing full travel at the end of thestick movement. The end result (travel)remains the same, although exponentialchanges the rate at which it achieves thistravel. The adjustable range is from 0-100%. Zero percent (0%) is linear stickcontrol, meaning the response rate isequal throughout the stick control. 100%is full exponential. The larger theexponential value, the less servo actionor sensitivity you will notice around theneutral setting.

CCPM Swashplate Mixing (continued)

CCPM is a type of pitch mixing wherethe two or three servos are connecteddirectly to the swashplate of the

helicopter and physically move togetherand independently for all changesin pitch/cyclic. Please refer to thediagram below.

1). One servo (StandardMechanical Mixing)

The most common form of SwashplateMixing. This type uses each of the threeservo to move the swashplate individuallyfor pitch, Aileron, and Elevator changes.If one servo (NORM) is selected in theSystem Mode (Factory Default), theSwashplate Type Function will not appearon the LCD screen in this section.

2). Two servo (180-degrees)Two servos are used to move theswashplate, and are spaced at180 degrees apart. This is not a verycommon control system configuration.

3). Three servo (120-degrees)Three servos are used to move theswashplate, and are spaced at120 degrees apart. This is the mostcommon form of CCPM, and is found inJR® and other brands of Helicopters.

4). Three servo (90-degrees)Three servos are used to move theswashplate, and are spaced at90 degrees apart. This is also not a verycommon control system configuration.

12I THROTTLE CURVES

The XP6102 offers two (2) separatethrottle curves with five adjustable pointsper curve. This function allows you tocustomize the throttle curve and pitchcurve together to maximize engineperformance at a particular pitch setting.Once the throttle curves are established,each can be activated in flight using thetwo (2) position flight mode switch.

The flight mode switch offers twoselectable ranges: Normal and Stunt. TheNormal position should be used as thehover throttle curve. The Stunt positionshould be used for aerobatic maneuversand forward flight.

Note: The throttle trim and hoveringthrottle levers are only operablewhen the flight mode switch is in thenormal position. Thus, in normalfunction it will have no effect. Also,adjusting the hovering throttle leverand throttle trim has no effect on theinput values of the throttle curve.

Each of the five points of the throttlecurve are independently adjustable from0–100%. These five points correspond tothe position of the throttle stick. Theillustration below shows the normalthrottle curve setting for the dead slowposition with throttle trim at default.

REVOLUTION MIXING (NON-HEADING LOCK GYROS ONLY)

The Revolution Mixing function mixes tailrotor with the Throttle and Pitch Curvefunctions to counteract torque from themain rotor blades. When set up correctly,the helicopter should climb and descendwithout a tendency to yaw in eitherdirection. Because torque reaction varieswith different power settings, it isnecessary to vary the tail rotor pitch atthe same time. The XP6102 offers two

separate revolution mixing programs,with independent up and down mixingfor each — one for Flight mode positionNormal and the other for Stunt. The upmixing adjusts the tail rotorcompensation for the mid to high throttlesetting and the down mixing adjusts thetail rotor compensation for the mid tolow throttle setting.

Setting Up Revolution Mixing (non-heading lock gyros only)

Set up the helicopter so that it will hoverwith the tail rotor trim centered. Establishthe helicopter into a stable hover, thensteadily increase the throttle to initiate asteady climb. The body of the helicopterwill move in the opposite direction to themain rotor rotation. Increase the U, orUp, setting until the helicopter climbs withno tendency to turn. At a safe altitude,close the throttle; the helicopter willdescend and the body will turn in the

same direction as the main rotor rotation.Increase the D, or Down, mix until thehelicopter descends with no tendency toturn. Throttle stick movements should beslow, and the initial acceleration anddeceleration swings should be ignored.

The Acceleration Mixing functionis provided to compensate for themain rotor acceleration (anddeceleration) torque.

PROGRAMMABLE MIXING (1-2)

The XP6102 offers two programmablemixes to be used for any number ofdifferent purposes. This function allowsmixing any one channel to any otherchannel. This mix can remain on at alltimes or be switched on and off in flightusing a number of different switches.

Mix number 1 is of the standard variety,in that the digital trim for the masterchannel only affect the master channel,and not the slave channel. Mix number 2is of the "Trim Include" variety. This mix isused any time the mix requires the slavechannels trim position to be varied whenthe master channels digital trim positionis varied.

Each channel of this radio is identified byan abbreviated name. The chart belowindicates the channel and itscorresponding abbreviation. The channelname appearing first is known as the"master channel" or the channel to whichyou want to mix. The second number isknown as the "slave channel" or thechannel that is being mixed into themaster channel. For example, AIL ➔RUD would indicate aileron-to-ruddermixing. Each time the aileron stick ismoved, the aileron will deflect, and therudder will automatically move in thedirection and to the value input.

Mixing is proportional, so small inputsof the master channel will produce smalloutputs of the slave channel. Eachprogrammable mix has a mixing "offset."The purpose of the mixing offset isto re-define the neutral position ofthe slave channel.

SERVO PRECAUTIONS 13A• Do not lubricate servo gears or motors.• Do not overload retract servos during

retracted or extended conditions.Make sure they are able to traveltheir full deflection. Overloading orstalling a servo can cause excessivecurrent drain.

• Make sure all servos move freelythrough their rotations and no linkageshang up or bind. A binding controllinkage can cause a servo to drawexcessive current. A stalled servocan drain a battery pack in a matterof minutes.

• Correct any control surface "buzz" or"flutter" as soon as it is noticed in flight,as this condition can destroy thefeedback potentiometer in the servo. Itmay be extremely dangerous to ignoresuch "buzz" or "flutter."

• Use the supplied rubber grommets andbrass servo eyelets when mountingyour servos. Do not over-tighten theservo mounting screws, as thisnegates the dampening effect of therubber grommets.

• Ensure the servo horn is securelyfastened to the servo. Use only the JR®

servo arm screws provided; the size isdifferent from other manufacturers.

• Discontinue to use servo arms whenthey become "yellowed" or discolored.Such servo arms may be brittle andcan snap at any time, possibly causingthe aircraft to crash.

•Check all related mounting screwsand linkages frequently. Aircraft oftenvibrate, causing linkages and screwsto loosen.

INFORMATION

GENERAL NOTES 13BRadio controlled models are a greatsource of pleasure. Unfortunately,they can also pose a potential hazard ifnot operated and maintained properly.It is imperative to install your radiocontrol system correctly. Additionally,your level of piloting competency mustbe high enough to ensure that you areable to control your aircraft under allconditions. If you are a newcomer toradio controlled flying, please seekhelp from an experienced pilot or yourlocal hobby shop.

Safety Do's and Don'ts for Pilots• Ensure your batteries have been

properly charged prior to initial flight.• Keep track of the time the system is

turned on so you will know how longyou can safely operate your system.

• Perform a ground range check prior tothe initial flight of the day. See the"Daily Flight Checks Section" forinformation.

• Check all control surfaces prior toeach takeoff.

• Use frequency flags.• Do not fly your model near spectators,

parking areas or any other area thatcould result in injury to people ordamage of property.

• Do not fly during adverse weatherconditions. Poor visibility can causedisorientation and loss of control ofyour aircraft. Strong winds can causesimilar problems.

• Do not fly unless your frequencyis clear.

Warning: Only one transmitter at a timecan operate on a given frequency. Ifyou turn on your transmitter whilesomeone else is operating a modelon your frequency, both pilots willlose control of their models. Onlyone person can use a givenfrequency at a time. It does notmatter if it is AM, FM or PCM—onlyone frequency at a time.

• Do not point the transmitter antennadirectly toward the model. The radiationpattern from the tip of the antenna isinherently low.

• Do not take chances. If at any timeduring flight you observe any erratic orabnormal operation, and immediatelyand do not resume flight until thecause of the problem has beenascertained and corrected. Safetycan never be taken lightly.

13C FEDERAL AVIATION ADMINISTRATION

1. PurposeThis advisory outlines safety standardsfor operations of model aircraft. Weencourage voluntary compliance withthese standards.

2. BackgroundAttention has been drawn to theincrease in model aircraft operation.There is a need for added caution whenoperating free flight and radio controlledcraft in order to avoid creating a noisenuisance or a potential hazard to full-scale aircraft and persons and/orproperty on the surface.

3. Operating StandardsModelers generally are concernedwith safety and exercise good judgmentwhen flying model aircraft. However,in the interest of safer skies, weencourage operators of radio controlledand free flight models to comply withthe following standards:

a. Exercise vigilance in locating full-scale aircraft (get help if possible) soas not to create a collision hazard.

b. Select an operating site atsufficient distance from populatedareas so you do not create a noiseproblem or a potential hazard.

c. Do not fly higher than 400 feetabove the surface.

d. Always operate more than threemiles from the boundary of anairport unless you are givenpermission to be closer by theappropriate air traffic control facilityin the case of an airport for which acontrol zone has been designated orby the airport manager in the caseof other airports.

e. Do not hesitate to ask forassistance in complying with theseguidelines at the airport trafficcontrol tower or air route trafficcontrol center nearest the site ofyour proposed operation.

13D DAILY FLIGHT CHECKS

1. Check the battery voltage on boththe transmitter and the receiverbattery packs. Do not fly below 9.0Von the transmitter or below 4.7V onthe receiver. To do so can crashyour aircraft.

Note: When you check thesebatteries, ensure that you have thepolarities correct on your expandedscale voltmeter.

2. Check all hardware (linkages, screws,nuts, and bolts) prior to each day'sflight. Be sure that binding does notoccur and that all parts are is properlysecured.

3. Ensure that all surfaces are moving inthe proper manner.

4. Perform a ground range check beforeeach day's flying session. The rangecheck should be as follows:

• Do not extend the transmitter antennaat this time. Turn the transmitter "on."

• Turn the model "on."• Slowly walk away from the model while

moving the control surfaces. Theaircraft should function properly at adistance of 60–75 feet.

5. Prior to starting your aircraft, turn offyour transmitter, then turn it back on.Do this each time you start youraircraft. If any critical switches are onwithout your knowledge, the transmitteralarm will warn you at this time.

6. Check that all trim levers are in theproper location.

7. All servo pigtails and switch harnessplugs should be secured in thereceiver. Make sure that the switchharness moves freely in both directions.
