Revised Users Manual Part 2

• Response direction:• Normal or reversed for all dials/trimmers, and switch 3.• Normal or alternate for switches 1 and 2.INTERACTION:• If multiples switches/dials/trims are assigned to do the same job, their settings are combined up to the limits of thefunction. For example, assigning steering trim to both DT1 and DL1 means moving either adjusts the trim from thecurrent position up to the maximum available trim. (Total trim available is still the same, not doubled.)• Digital: Since the dials and trims are digital, their physical position does not matter to the model memory. If a dial ortrim is bumped when both switches are off, no change is made to the position remembered in the memory. Forexample, turn on the display. Note the steering trim position shown on screen. Turn the display off. With the displayoff, press the digital trims. Now turn the display back on. Note that the trim has not changed. The same is true for thedigital dials, meaning no more need to try to “store” or “set” the dial positions before changing model memories toavoid unintentional changes in your other models!DESIRED END RESULT: Create driver-specific setups for each car for easy adjustment of features on-the-fly.CAUTION: Be sure you know what each switch/dial/trim is doing prior to every operation.35GOAL:Assign idle-up to the push button switch onthe radio’s handle (SW2 aka PS2), whileusing LV2 menus. (If using LV3, selectFUNC-SW from menu 2.) (If using LV1, firstchange level selection to LV2, p. 12.)Assign throttle acceleration forward side togrip dial 1 and brake side to grip dial 2.Adjust steps to 1% for very fine adjustments.Where Next:STEPS:Open and select menu 2.Select FUNC-SW.Select switch #2 (SW2 aka PS.2).Set function to idle-up.Reverse switch direction to have idle-upon unless button is held.Close function and menu.Open and select menu 2.Select FUNC-DIAL.For dial 1, select acceleration forward.Set step to 1%.Select dial 2, acceleration braking.Set step to 1%.Reverse dial direction so turning dial 2backward increases braking side ofacceleration, turning dial 1 forwardincreases throttle side acceleration.Close function and menu.INPUTS:to SW2.to IDLE-UP.to ALT.9 times to ACC-F.to 1.9 times to ACC-B.to 1.Use servo screen to see effectiveness of dial/switch changes (SERVO) (LV3): See p. 39.Set up throttle acceleration (TH-ACCEL): See p. 26.Set up ABS (ABS): See p. 24.Set up servo speed (ST-SPEED, TH-SPEED): See p. 23.Set up tilt mixing (BOAT-MODE) (LV3): See p. 43.Set up brake mixing (BRAKE-MIX) (LV3): See p. 42.Let’s do a dial setup now.
36Direct Selection Menu Options DIRC-CALL Levels LV2, LV3 OnlyDEFINITION: Customize what functions are available at the push of 2 buttons(Direct menu and one more) by adjusting the Direct Selection menu. Note thatdirect menu selection/exit is always the DIR button.AVAILABLE FOR: N/A.ADJUSTABILITY: All functions are assignable to the 6 available buttons.INTERACTION: None.DESIRED END RESULT: 2-button access to the 6 most frequently usedfunctions, such as model selection, timer, auto-start (to reset for next use) orother functions you are currently fine-tuning for your model.CAUTION: The direct button opens the direct selection menu and closes it again, regardless of where you are inthe programming. That function can not be assigned elsewhere, and nothing else can be assigned to that key.GOAL:Customize direct select menu so button 1opens auto-start and button 6 goes totimer, while using LV2. (If using LV3, selectDIRC-CALL from menu 3.) (If using LV1,first change level selection to LV2, p. 12.)Where Next:STEPS:Open and Select menu 2.Select DIRC-CALL.Edit button 1 to auto-start.Select button 6.Edit button 6 to timer.Close function and menu.Press direct key to open direct menu.Select Auto-start.Return to direct menu.Close menu.INPUTS:to AT-START.11 times to TIMER.Change switch assignments (FUNC-SW): See p. 34-35.Change dial assignments (FUNC-DIAL): See p. 34-35.
LV3 FUNCTIONS for the Expert Driver, Boats or Complex ModelsLevel LV3 Only Programming Adjustment of Throttle ATL ATLDEFINITIONS: •ATL, electronic: (Adjustable throttle limiter) Adjusts total travel available to thebraking side of the throttle servo, similar to adjusting EPA, but allows adjustment“on the fly” when ATL is assigned to a dial. When brake mixing is used in theunmixed mode, this adjusts the rear brake servo without changing amount of brakingto front brake servo.•ATL, mechanical: Decreases the physical distance the brake trigger can move.See p. 51.AVAILABLE FOR: Braking only.ADJUSTABILITY: • RATE: 0 (no braking at all) to 100% (same as EPA). Default: 100%.• Rate adjustment: May be easily adjusted while driving (if assigned to a dial/trim, see FUNC-DIAL, pp. 34-35). Defaultassignment is to gripper dial 2.INTERACTION: EPA affects total travel available to the servo. ATL is directly proportional to EPA.DESIRED END RESULT: Quickly adjust overall braking sensitivity, including with a dial while driving on the track.CAUTION: Dial 2 is assigned for ATL adjustment as a default, even if user does not realize it.37GOAL:While using LV3:•Reassign the ATL adjustment to digitaltrim 1; •Adjust the ATL setting from 100% to20% (with the digital trim centered).(If using LV1 or LV2, first change levelselection, see p. 12.)Where Next:STEPS:Use FUNC-DIAL to assign ATL to digitaltrim 1.While viewing home screen, adjust digitaltrim 1 until ATL reads 0.Select ATL.Adjust ATL to 20%.Close function and menu.INPUTS:9 steps to DT1.to ATL. Move trim 1, if necessary, until displayreads 0for ATL.to 20%.Adjust the throttle servo’s EPA (EPA):See p. 18.Set up channel 3 control (CH3-POSI):See p. 40.Set up brake mixing for separate front/rear brakes (BRAKE-MIX):See p. 42.Set up tilt mixing for boats (BOAT-MODE):See p. 43.
Steering Dual Rate ST-D/R Level LV3 OnlyDEFINITIONS: •Dual Rate, or primary dual rate: Decreases the vehicle’s steering sensitivityacross the entire range. Equivalent of decreasing steering EPA by that percentage.Assigned to grip dial 1 as a default to allow on-the-course adjustments. If grip dialis unassigned, dual rate may still be adjusted on-screen. Dual rate is always active,except when the 2nd dual rate switch is pushed. (3PK’s dual rate is the same as the9Z’s AFR, and the first rate of dual rate in other aircraft style radio models.)•Second Dual Rate: A second while-driving rate of servo response, availablewith the push of a switch. The 2nd dual rate is meant to be used to temporarilyhave more/less servo travel available without having to readjust the dual ratedial. Second dual rate is proportional to the EPA not the primary dual rate.Examples: Used for getting away from walls, crashes, a single hairpin turn on anotherwise non-technical track.AVAILABLE FOR: Steering only.ADJUSTABILITY: • RATE: 0 (no steering at all) to 100% (same as EPA). Default: 100%.• Switch assignment (to change from primary dual rate to second dual rate): Must be set using FUNC-SW, see pp. 34-35. Default: no dual rate switch assigned; 2nd dual rate is not usable until a switch is assigned.• Rate adjustment: Both primary rate and 2nd rate adjustments may be assigned to any dial/digital trim (see FUNC-DIAL,pp. 34-35) to allow adjustment while driving. If no dial/trim is assigned, then adjustments are made only within theD/R function. Defaults: D/R on dial 1, 2nd D/R not assigned.INTERACTIONS:• EPA affects total travel available to steering servo. Both dual rates are directly proportional to the total EPA.• Exponential adjusts how much the servo is moved around center without having any effect on the servo travel at fullstick; dual rate uniformly decreases the servo’s movement all along the travel.• Speed Limiter slows how quickly the servo moves to a certain point without decreasing its overall travel rather thandecreasing the servo’s movement to decrease its sensitivity.DESIRED END RESULT: Quickly adjust steering overall sensitivity with a dial while driving on the track; have a secondtravel rate available for unusual situations, such as a crash.CAUTION: Dual rate is active as a default and is adjusted from normal setting (100%) with dial 1 unless it isreassigned by the user.38
Level LV3 Only Servo View SERVODEFINITION: Shows the exact outputs the transmitter is sending to the servos. Allowsfor easy testing/experimenting even when receiver and servos are not yet installed.AVAILABLE FOR: throttle, steering, channel 3.ADJUSTABILITY: N/A.INTERACTION: Shows all servo interactions from programming.DESIRED END RESULT: Confirm programming is having desired result beforeradio gear is set up in model.39GOAL:While using LV3:•Reassign digital trim 1 to the dual rateadjustment;•Assign dual rate switching to switch 1;•Adjust 2nd dual rate to slightly less thanmaximum (95%) for quick steering to getout of tight spots.(If using LV1 or LV2, first change levelselection, see p. 12.)Where Next:STEPS:Use FUNC-DIAL to assign dual rate todigital trim 1.Use FUNC-SW to assign dual rate switchingto switch 1.Select dual rate.Test the dual rate adjustment by movingdigital trim 1.Adjust 2nd dual rate down to 95%.Test the 2nd dual rate switch by pressingswitch 1.Close function and menu.INPUTS:9 steps to DT1.12 steps to D/R. to D/R 2nd.Move digital trim 1 counterclockwise; seethe rate decrease on-screen. (Note that therate per click can be adjusted in thefunction dial screen.)to 95.Press switch 1 (below the wheel) and notice2nd D/R Rate changes from OFF to ON, asprimary rate changes from ON to OFF.Adjust the steering servo’s EPA (EPA): See p. 18.Adjust steering channel exponential (ST-EXP): See p. 20.Adjust steering servo response speed (ST-SPEED): See p. 23.Set up channel 3 control (CH3): See p. 40.Set up brake mixing for separate front/rear brakes (BRAKE-MIX): See p. 42.Use servo screen to see exactly how dual rates are performing (SERVO): See below.GOAL:View screen after setting up steering dualrate to confirm switch and dials areworking as planned, while using LV3. (If using LV1 or LV2, first change levelselection, see p. 12.)Where Next:STEPS:Set up dual rates.Select servo display.Close function and menu.INPUTS:See page 38.Return to function and make adjustments as needed, or complete installation in model.Holding full right turn, adjust dial to see change in total servo throw, then hold dualrate switch, and notice change in total throw.
Channel 3 Control CH3-POSI Level LV3 OnlyDEFINITION: Sets the default or neutral position for the channel 3 servo.Defaults to being adjustable with dial 3.AVAILABLE FOR: channel 3 only.ADJUSTABILITY: -100% to 0 to +100%. Default adjusts with dial 3, may bereassigned with FUNC-DIAL (see pp. 34-35).INTERACTION: Channel 3 position is relative to channel 3’s EPA.DESIRED END RESULT: Fine tune the channel 3 neutral position. May also beused to adjust channel 3 to a specific position and leave it there if adjustabilityis not assigned to a dial (see FUNC-DIAL, pp. 34-35).CAUTION: Dial 2 defaults to ATL adjustment, even if user does not realize it.Programmable Mixes PRG-MIX1, PRG-MIX2 Level LV3 OnlyDEFINITIONS: • Programmable mixing function: Allows user to create mixing between thesteering, throttle and channel 3 servos. Brake mixing is an example of built-in mixes.• Master: The channel the slave will follow. In brake mixing, the throttlechannel’s braking side.• Slave: The channel that follows the master. In brake mixing, channel 3 (front brakes).• Offset: Amount off center to adjust the mix.• Mix Mode: Selects whether slave moves exactly based upon the master control’smovement (unmixed) or the master channel’s servo movements after any mixing(mixed). Brake mixing unmixed means front brakes respond exactly based upontrigger position while rear braking is changed by ABS, Speed Limiter, etc.• Trim: Sets whether the slave channel is (ON) or is not (OFF) adjusted with themaster when using the master channel’s trim.AVAILABLE FOR: Throttle, steering, channel 3.40GOAL:While using LV3:•Reassign the channel 3 adjustment todigital trim 3; •Adjust the channel 3 “center” position from0 to 18% (with the digital trim centered).(If using LV1 or LV2, first select level LV3,see p. 12.)Where Next:STEPS:Use FUNC-DIAL to assign CH3 to digitaltrim 3.While viewing home screen, adjust digitaltrim 3 until 3CH reads 0.Select channel 3 positioning.Adjust channel 3 position to 18%.Close function and menu.INPUTS:to DT3.to CH3. Move trim 3, if necessary, until displayreads 0for 3CH.to 18.0%.Adjust channel 3 servo’s EPA (EPA): See p. 18.Set up brake mixing to use channel 3 for separate front/rear brakes (BRAKE-MIX): See p. 42.Set up tilt mixing to use channel 3 for boats (BOAT-MODE): See p. 43.Set up programmable mixes to use channel 3 (PRG-MIX1,2): See below.
ADJUSTABILITY: • Master: Throttle, steering, channel 3.• Slave: Throttle, steering, channel 3.• A and B adjustments [Up/forward/left and down/brake/right (for ch3/throttle/steering respectively)]: -100% (moveexact opposite of master) to 0 (no movement of slave) to +100% (move exactly same as master). Default: 50%.Adjustable while in use by selecting a dial/trim for programmable mix adjustments A and B in FUNC-DIAL, pp. 34-35.• Offset: -100% to 0 to +100%. Default: 0%.• Master mixed mode: Off, mixed. Default: off.• Trim: Off, On. Default: Off.• Switch: An on/off switch may be assigned for each mix in FUNC-SW (see pp. 34-35).INTERACTION: EPA affects total travel available to both servos. Master mixed mode “mixed” means that all otherfunctions affecting the primary channel also affect the secondary channel.DESIRED END RESULT: Varies based upon user setup.CAUTION: Be sure to test all mixes at every step to ensure no unexpected difficulties occur.41GOAL:Set up a programmable mix from steeringto lights so that headlights turn withsteering wheel, while using LV3. (If usingLV1 or LV2, first select level LV3, see p. 12.)STEPS:Select programmable mix 1.Make mix active.Set master channel as steering.Set slave channel as ch 3.Set left and right travel as 100%.Set master mixed mode to mixed so othermixes affecting throttle position alsoaffect headlight angle.Set trim on so movement of steering trimalso moves headlights.Close function and menu.INPUTS:to ACT.(already steering)to CH3.to 100%. to 100%.to MIX.to ON.GOAL:Use mixes to increase steering travel slightlywhen dual rate and EPA are not enough,while using LV3. [Note that anything morethan 10% (or less if subtrim is >0) will notmove the servo any further, as the servo’smaximum mechanical travel is exceeded. Besure to check actual travels, including subtrims, by testing servo operation.] (If usingLV1 or LV2, first select level LV3, see p. 12.)Where Next:STEPS:Select programmable mix 1.Make mix active.Set master channel as steering.Set slave channel as steering.Set left and right travel as 10%.Leave offset at 0 and trim off.Set master mixed mode to mixed so othermixes affecting steering also. See theincrease.Close function and menu.INPUTS:to ACT.(already steering)to ST.to 10%.to 10%.to MIX.Programmable mix to set up differential steering (similar to the brake mixing programbut for 4-wheel steering or for 2-wheel steering using 2 servos and creating adjustableacumen): see www.futabarc.com\faq\faq-3pk.htmlAdjust steering EPA (ST-EPA): See p. 18.Adjust steering dual rate (ST-DR): See p. 38.Adjust steering subtrim (SUB-TRIM): See p. 22.
Multiple-Servo Brake Mix BRAKE-MIX Level LV3 OnlyDEFINITIONS:• Brake Mix: Used when model has separate front and rear brakes, and they must beadjusted separately. Uses channel 2 for rear brakes/throttle, channel 3 for front brakes.• RATE: Proportion of total front brake travel applied when full rear brake is applied.• DELAY: Waits to brake either front or rear, allowing the other to brake first.• BALN: Balance. Adjusts the proportion of front to rear braking.• TGP: trigger point. At what amount of trigger the brake mixing takes effect.• MXMD: Mixing mode. Front brakes respond based solely on trigger position(UNMIX), or other functions’ adjustments to rear brakes, such as ABS, also effectfront brakes (MIXED).AVAILABLE FOR: N/AADJUSTABILITY: • RATE: 0 (no front braking) to 120% (front brake servo moves 20% more than rear brake).• DLY: 0 (no delay) to 100% (maximum delay, about 2 seconds); F (front) or R (rear). Either F or R MUST be 0;may both be 0.• BALN: 80 (decreased braking) -100% (no change), F or R. Either F or R must be 100%, may both be 100%.• TGP: 10 (front brakes active even with small amounts of brake) – 100% (front brakes applied only when full brake given.)• MXMD:UNMIX (front brake obeys trigger position only); MIXED (front brake obeys all braking mixes).INTERACTIONS:• ABS, Speed Limiter, exponential, etc., all affect the rear brake; mix mode MIXED causes them to also affect the front.• Mixing is based upon total EPA of each servo. Example: Rear servo moves 60° at 100 EPA. Front servo moves 40°at 100 EPA. Rate of 100% moves front servo full 40° when rear servo moves 60°. Rate of 120% means front servomoves 40° times 120%, or 48°, when rear servo moves 60°.DESIRED END RESULT: Model brakes as rapidly as possible without negative handling effects such as squatted shocks, etc.CAUTION: Unmixed results in the front brake getting drastically different inputs than the rear when functions suchas ABS are used (no pulsing on front).42GOAL:While using LV3, setup brake mixing for1/5th scale offroad vehicle, with front brakeresponding 75% as much as rear, with aslight delay to allow rear brakes to respondfirst, no change in balance, front brake ononly after 80% brake and front/rear bothobeying ABS mixing. (If using LV1 or LV2,first select level LV3, see p. 12.)Where Next:STEPS:Open and select menu 1.Select BRAKE-MIX.Activate brake mixing.Adjust rate to 75%.Adjust front delay to 10.Adjust trigger point to 80%.Set to mixed mode to use all rear brakemixing for front brakes also.Close function and menu.INPUTS:to ACT.to 75.to 10.to 80.to MIXED.NOTE: All of these functions interact with the throttle servo as well and are all inter-related.Adjusting any one may affect the performance of the others as described in interactions.Adjust the throttle servo’s EPA (EPA): See p. 18.Adjust overall braking speed (TH-SPEED): See p. 23.Adjust throttle exponential (TH-EXP): See p. 20.Adjust ABS braking (ABS): See p. 24.Set up smooth acceleration off of the start and also engine cut (AT-START): See p. 28.
43Level LV3 Only Boat Mode BOAT-MODEDEFINITIONS: • Boat mode: Set ups to fit specific needs of boat models rather than cars.• TRG-BRK: Trigger-Brake operation. Shuts off brake side of servo movement forboats without braking/reverse.• Tilt Mixing: adjusts outboard engine positioning with rudder inputs, and adjustsrudder with outboard engine adjustments.• Channel 1 > 3: mix from steering (rudder) to outboard. Utilized when theboat drops too much (or too little) into the water when giving rudder input.• Channel 3 > 1: mixing from outboard to steering (rudder). Utilized when the torque of the engine has more effect as the boat’s positionchanges in the water, causing the boat to yaw left under acceleration.AVAILABLE FOR: N/AADJUSTABILITY: • TRG-BRK: Normal (brake operates); cut-off (no brake/reverse operation).• CH 1>3 and CH 3>1: -100% (moves exactly opposite) to 0 (no mix) to +100% (moves exactly the same as master.)INTERACTIONS:• EPA, steering expo, speed, dual rate, etc., all affect the 3rd channel (master mixing is on and can not be set to off.)• Reversing the channel 1 servo does NOT reverse the channel 3 servo.DESIRED END RESULT: Keep outboard-powered boat up on its step and traveling straight at high speeds/rapidacceleration, and adjust the boat’s angle in the water for ideal turning with minimum drag.CAUTION: Remember, EPA of channel 1 affects channel 3, so check for binding after all changes.GOAL:Set up an outboard boat’s engine tilt to setthe boat lower in the water when turningfor better “bite,” while using LV3. (If usingLV1 or LV2, first select level LV3, see p. 12.)Where Next:STEPS:Open and select menu 2.Select BOAT-MODE.Turn off brake function.Activate tilt mixing.Adjust channel 3 to 1 (outboard to steering)mixing to 0 (disabling it).Decrease rudder-to-outboard to 20%.Close function and menu.INPUTS:to CUT OFF.to ON.to 0.to 20.Adjust the throttle servo’s EPA (EPA): See p. 18.Adjust channel 3’s center point (CH3-POSI): See p. 40.Change channel 3’s control (FUNC-DIAL): See pp. 34-35.Assign channel 3 to 1 mixing to a dial to adjust while in use (FUNC-DIAL): See pp. 34-35.Set up engine cut (AT-START): See p. 28.Set up steering dual rates (ST-D/R): See p. 38.
Fine Tuning ESC Readability (for HRS receivers ONLY) MC-SETUP Level LV3 OnlyDEFINITION: Adjusts frame rate of transmitter output to throttle channel forsetting up non-Futaba ESCs with HRS systems. HRS frame rate is faster than allother products currently sold in the US, and some non-Futaba speed controls cannot properly read the output to complete their auto setups, making setup difficult.AVAILABLE FOR: HRS receivers ONLY.ADJUSTABILITY: N/A.INTERACTION: Must be used only with HRS receivers, and only with speedcontrol properly connected, using the proper cords (not included), as shown below.DESIRED END RESULT: Quick, easy setup of non-Futaba ESCs with HRS receivers.CAUTIONS:• ONLY use with HRS receivers/modulation.• MUST use the two-way cord and DSC cord toconnect ESC directly to transmitter to completethis setup.• Transmitter switch MUST be turned off after setupis executed or the amp mode cannot be reset andthe system can not transmit properly. Warning willdisplay “CAUTION! NOW MOD OFF”.44GOAL:Complete auto-setup of a non-Futaba ESCthat is not setting up properly on its ownwhen in use with an HRS receiver, whileusing LV3. (If using LV1 or LV2, first selectlevel LV3, see p. 12.)Where Next:STEPS:Be sure transmitter is in HRS mode.Set up DSC/two-way cord.Select MC-SETUP function.Activate amp setup.Adjust front delay to 10.Close function and menu.INPUTS:See modulation, p. 16.See setup diagram above.for at least one second.Adjust subtrim until motor is not spinning at neutral (SUB-TRIM): See p. 22.Setup ABS braking (ABS): See p. 24.Adjust throttle/ESC speed to minimize wheel spin (TH-SPEED): See p. 23.Setup throttle acceleration for spin-free starts (TH-ACCEL): See p. 26.Follow manufacturer’s auto-setup instructions for ESC.TURN TRANSMITTER OFF. (Transmitter can not transmit until power is cycled.)
Level LV3 Only Electronic Centering Calibration Adjuster ADJUSTERDEFINITION: Calibrates electronic positioning to mechanical movement ofcontrols. Even if you never have a crash, your R/C vehicle needs occasionalalignments and mechanical adjustments to keep it “in tune” and in trim.Similarly, all transmitters need regular maintenance to keep everything properlyaligned. But unlike all other transmitters which just have to be driven “as is”until professionally adjusted/repaired, you can temporarily adjust your 3PK tokeep driving as if it were new, then happily wait until your non-racing seasonwhen you can send it for its regular maintenance.AVAILABLE FOR: Throttle, steering.ADJUSTABILITY: Neutral and left/right vs. neutral/brake.INTERACTION: Adjuster affects the mechanical position the radio thinks is center/neutral, and also the end points.Correcting any minor slippage/wear in the transmitter with adjuster will temporarily correct the out of trim problems untilthe radio can be serviced. All programming functions operate based upon the radio’s neutral and full left/right orneutral/brake positioning.DESIRED END RESULT: Correct for minor slippage/wear/drift in the steering and throttle to provide like-new performance.CAUTIONS: • Need for regular service: Slippage is a sign of wear to the transmitter. Be sure to have your radio servicedregularly (we recommend annually) to check for/service other wear and tear on the radio and also to ensureproper transmitter tuning.• Correction range: If the adjustment point shown is not close to the default settings (100%, 0, 100%), the systemwill not store the new positions, and an error message of “FAIL! NOT CHANGED” is displayed. Retry process. Ifdata can not be stored, the radio is too far out of alignment to use. Send for service promptly (see p. 4).45GOAL:Complete software adjustment to fix steeringmechanical offset.Where Next:STEPS:Open menu 3 and select adjuster.Select steering.Set steering neutral.Set left and right ranges.Confirm desired correction.Close function and menu.INPUTS:Lightly pull on the steering wheel, pulling itaway from the transmitter. Let go andLightly turn wheel full left, let go, turn fullright. Let go andBack to the track!

47MEANING OF SPECIAL MARKINGSPay special attention to safety where indicated by the following marks:DANGER - Procedures which may lead to dangerous conditions and cause death/serious injury if not carried out properly.WARNING - Procedures which may lead to a dangerous condition or cause death or serious injury to the user if notcarried out properly, or procedures where the probability of superficial injury or physical damage is high.CAUTION - Procedures where the possibility of serious injury to the user is small, but there is a danger of injury, orphysical damage, if not carried out properly.= Prohibited = MandatoryWarning: Always keep electrical components away from small children.To ensure the safety of yourself and others, please observe the following precautions:Have regular maintenance performed. Although your radio does not have a battery to protect the model memories,it still should have regular checkups for wear and tear. In the US, we recommend sending your system to the USFutaba Service Center annually for a complete checkup and service.CAUTION - Before Using Your System…1. ALWAYS be sure the receiver, servo(s), ESC, crystal and connectors are fully connected prior to every operation.Vibration, which occurs in all models, means regular inspections and maintenance are critical.2. ALWAYS protect the receiver and NiCd battery from vibration by mounting them in thick double-sided tape or foam.3. Aquatic users: ALWAYS protect all radio equipment from potential water damage by waterproofing. Send anyequipment subjected to water, fuel or other corrosive materials for testing prior to re-use.4. NEVER cut or coil your receiver antenna or bundle it with any servo leads, battery wires, carbon fiber, metal orother conductive materials.5. ALWAYS keep the receiver antenna at least 1” away from motor/battery/ignition/other wiring carrying heavy current.6. Electric Users: ALWAYS install the ESC heat sinks such that they can not come into contact with plastic,aluminum, carbon fiber, or other conductive materials, or a short circuit may occur.7. ALWAYS operate each servo full distance both ways and check for buzzing, binding, loose linkages, chatter, or“stepping” in the movement (check for broken servo gears).8. ALWAYS use the rubber grommets for servo installation, and ensure the servos do not come into direct contactwith the mount or anything that conducts electricity.9. Electric Users: ALWAYS install capacitors on electric motors to suppress electrical noise.10. ALWAYS inspect your model for metal-to-metal contact (including while engine/motor is running) which couldcreate electrical noise and result in erratic system operation.11. ALWAYS range check your system.12. NEVER leave the radio system or models within reach of small children. NiCd batteries can be very dangerouswhen mishandled and can cause chemical damage.13. NEVER store your radio equipment and models where they will be exposed to extreme heat or cold, directsunlight, high humidity, large quantities of dust, steam or condensation.14. NEVER expose the plastic parts of your radio system to raw fuel, oil, exhaust, water.15. NEVER touch the engine, motor, speed control, or any other part of the model which generates heat duringoperation until the model is not operating, has been fully turned off and allowed to cool. These parts may be veryhot and can cause serious burns.16. ALWAYS display a frequency flag when operating your model.17. NEVER operate this R/C system when you are tired, not feeling well, or under the influence of alcohol or drugs.18. NEVER operate near other radio control activity areas, on any ponds or lakes where rowboats or swimmers arepresent, or near high tension power lines or communications broadcasting antennas.
48Charge the batteries! (See Caring for your NiCd batteries, p. 49, for details.) Always recharge the transmitter andreceiver batteries for at least 8 hours before each session. A low battery will soon die, causing loss of control and acrash. When you begin your session, reset your radio's built-in timer, and during the session pay attention to theduration of usage.Stop operating your radio long before your batteries become low on charge. Do NOT rely on your radio’s lowbattery warning systems, intended only as a precaution, to tell you when to recharge. Always check yourtransmitter and receiver batteries prior to each use.Before operating, make sure that your frequency is not already in use, and secure any frequency control device(pin, tag, etc.) for that frequency before turning on your transmitter. It is never possible to operate two or moremodels on the same frequency at the same time. Even though there are different types of modulation (AM, FM,PCM) and brands, only one model may be operated on a single frequency at any one time.To prevent possible damage to your radio gear, turn the power switches on and off in the proper sequence:1. Position throttle at idle, or otherwise disarm your motor/engine.2. Turn on the transmitter power and allow your transmitter to reach its home screen (if applicable.)3. Confirm the proper model memory has been selected (if applicable.)4. Fully extend the transmitter antenna.5. Turn on your receiver power or speed control power switch.6. Test all controls. If a servo operates abnormally, don’t use until you determine the cause of the problem. (For PCMand HRS systems only: Test to ensure that the FailSafe settings are correct by waiting at least 2 minutes afteradjusting; then, turn the transmitter off and confirm the proper servo movements. Turn the transmitter back on. Seepage 17 for details on FailSafe functions.)7. Complete a full range check.8. After use, bring your throttle to idle, engage any kill switches or otherwise disarm your motor/engine.9. Turn off receiver power.10. Turn off transmitter power.If you do not turn on your system in this order, you may damage your servos or control surfaces, flood your engine, or in thecase of electric-powered or gasoline-powered models, the engine may unexpectedly turn on and cause a severe injury.If you place your transmitter on the ground, be sure that the wind won’t tip it over. If it is knocked over, controlsmay be accidentally moved. Also, damage to your transmitter may occur.Before running the model, be sure to extend the transmitter antenna to its full length. A collapsed antenna willreduce your range and cause a loss of control. Try to avoid pointing the transmitter antenna directly at the model, since thesignal is weakest in that direction.Don’t operate in the rain, drive unprotected electronics through puddles or use when visibility is limited! Water ormoisture may enter the transmitter through the antenna or other openings and cause erratic operation or loss of control. If youmust use in wet weather during a contest, be sure to cover your transmitter with a plastic bag or waterproof barrier. Never useif lightning is expected.MANDATORY PROCEDURES for use with the High Response System (HRS) receiversUse ONLY:•Servos: Unregulated 6-Volt compatible Digital servos•Battery: 6-Volt Unregulated NiCd or NiMH battery•Mode: Transmitter MUST be set to HRS mode (see p. 7 and p.16 for details)•Transmitter: Futaba’s 3PK is the first radio sold in the US with HRS capability. At this time, only the 3PK may beused with the HRS receivers. Be sure to check any other transmitter’s operator’s manual before attempting to use withan HRS receiver.•NOTE: Do not attempt to operate with the Futaba FailSafe Unit (FS1) with an HRS receiver. Instead use the FailSafesettings built into the transmitter. (see p. 17 for details.)
49CARING FOR YOUR NiCd BATTERIESCharging Your System’s Batteries1. Connect the transmitter charging jack and receiver NiCd batteries to the transmitter and receiverconnectors of the charger.2. Plug the charger into a wall socket.3. Check that the charger LED lights. The initial charge, and any charge after a complete discharge,should be at least 18 hours to ensure full charge. Thebatteries should be left on charge for about 15 hours whenrecharging the standard NiCd batteries after normal use.You should fully discharge your system’s batteries periodically to prevent a condition called memory. If youregularly use only a small amount of the battery's capacity, the memory effect can reduce the actual capacity even if thebattery is fully charged. You can cycle your batteries with a commercial cycling unit*, or by leaving the system on andexercising the servos by moving the transmitter sticks until the transmitter shuts itself off. Cycling should be done everyfour to eight weeks, even during the winter or periods of long storage. Keep track of the batteries’ capacity during cycling;if there is a noticeable change, you may need to replace the batteries.*Note that your 3PK transmitter system is protected from overcharge. If the battery is charged with a quick charger forother than digital RC systems, it may not be fully charged. NiCd Handling Precautions•CAUTION - NiCd electrolyte is a strong alkali. Should you come in contact with even the smallest amount:•EYES: DO NOT RUB, wash immediately with water, and seek medical attention at once. The electrolyte cancause blindness.•CLOTHING/SKIN: Wash with water immediately. Seek medical attention if rash occurs.•DO NOT attempt to charge your 8-cell transmitter pack on the 4-cell receiver plug of the wall charger!•NEVER plug charger into an outlet other than the standard voltage (US is 110V).•NEVER insert or remove the charger while your hands are wet.•ALWAYS use the provided charger or a quick charger specifically for remote control modeling. Overcharged NiCds can result in severe burns, fire, breakage, or electrolyte leakage.•NEVER try to recharge an alkaline dry cell battery.•ALWAYS disconnect the radio from the charger and the charger from the wall when not in use.•ALWAYS double-check that your batteries are fully charged prior to use.•ALWAYS remove or disconnect the receiver NiCd when the vehicle is not in use to avoid accidental turn-ons.•NEVER use commercially provided single NiCd battery cells. Charging these cells in your R/C system or withR/C system chargers may result in damage to the equipment and chargers.•NEVER drop the NiCd battery or expose it to strong shock or vibration. Crashed equipment should always be sentfor service to test for internal damage.•NEVER leave the R/C system or batteries within the reach of small children.•ALWAYS store the system with the batteries in a discharged state and in a cool/dry place.•ALWAYS remove the transmitter and receiver batteries from the transmitter/vehicle for long-term storage.ChargerTX: Transmitter charging indicatorRX: Receiver charging indicatorTo transmitter charging jackReceiver Ni-Cd battery
50Mechanical ATL Adjustment: Make this adjustment when you want to decrease the total travel of the brake (push) sideof the throttle trigger. For digital ATL, see p. 37.Note: This is a mechanical stop screw only, and does not move the neutral point or affectthe acceleration (pull) side of the throttle trigger. Creating a shorter stroke allows formore rapid response when the linkage or end point is adjusted to create the same totalservo travel.Adjustment: Using a Phillips screwdriver, adjust the trigger brake (back) stroke byturning the screw through the adjusting hole indicated by the arrow in the figure. (Thescrew moves the throttle trigger stopper.)•When the adjusting screw is turned clockwise, the stroke becomes narrower. Makethis adjustment when you want to make the throttle trigger brake (back) stroke smaller(more responsive).CAUTION - When the stroke is adjusted, the throttle servo travel must be adjusted by linkage or programmed settingto gain the same total movement.Wheel Tension Adjustment: Make this adjustment when you want to change the steeringwheel spring tension.Adjustment: Turn the screw inside the adjusting hole using a 1.5mm hex wrench.•Turning the adjusting screw clockwise increases the spring tension.CAUTION - If turned too far counterclockwise, the adjusting screw may fall out.Note: To adjust the wheel and trigger calibration, see ADJUSTER p. 45.Mechanical ATLadjusting screwTension adjustingscrewAPPENDIX IIAdjustments, modifications and replacements

If 2 or more radios transmit on thesame frequency, or channel, glitching will occur in the receiver, due to conflicting signals sent by the two radios. Racingsites should have a frequency control system to ensure that only one radio operates on any given channel at one time. Thisis usually a board with some type of marker for each channel. If the marker is not available, someone else is using thatchannel. Do not use your radio unless you are sure you are the only one on the frequency.Channel: The number of functions your radio can control. Ex: A 3-channel radio has 3 available servo slots used for separatecontrol surfaces or switches.

In a coreless design, the armature uses a thin wire mesh that forms a cup that spins around the outside of themagnet eliminating the heavy steel core. A coreless motor does not have magnets as standard servo motors do, so they havea smoother, more constant, and stronger action. Regular servo motors have either 3 or 5 magnets (poles) which, when thearmature is between these, the servo motor is at its weakest.Count Down Timer: See Timer ..........................................................................................................................................30Count Up Timer: See Timer ...............................................................................................................................................30Curve: In throttle exponential, the “curve” function offers 5 points along the range of the servo, and draws straight linesof response between each point.

The FCC has allowed the 75mHz band (75.410 - 75.990) to be used for R/C ground model operations,and the 27mHz band (26.995 - 27.255) for ground and air models. This band is divided up into many different channels onwhich you can choose a radio system. You should be aware that certain areas have frequencies in which there is pager andother interference. This is why it is always a wise move to check with your local hobby shop to find out any channels thatmay be troublesome in the area. The FCC has allocated the 50mHz band (50.800 - 50.980) only to Amateur HAM licenseholders for R/C use (and only at 1W maximum power output.)Frequently Asked Questions webpage: www.futabarc.com/faq/faq-3pk.htmlFUNC-DIAL: See Function Assignment. ...........................................................................................................................34FUNC-SW: See Function Assignment. ...............................................................................................................................34Function: A programming option within the radio, such as exponential, brake mixing, etc.Function Assignment: assigns functions to the 3 dials, 3 trimmers, and 3 switches on the radio.

M1-M10: Model numbering for model memories stored within the transmitter’s memory, not in the optional CAMPac.Mandatory Procedures for using with HRS receivers ................................................................................................5, 48Master: In programmable mixing, the channel the other servo will follow. In brake mixing, the throttle channel’s brakingside. See Programmable Mixes ............................................................................................................................................40MC Setup (for HRS receivers only): HRS provides a very rapid frame rate – faster than most non-Futaba ESCs aredesigned to read/comprehend. Therefore, most non-Futaba ESCs’ self-setup procedures are unable to complete the self-setups and self-tests properly at this high frame rate. The MC Setup function, along with a special cord (not included),allow the receiver to communicate with the ESC temporarily at a slower frame rate so the ESC can properly set up and beprepared to operate properly in HRS....................................................................................................................................44MC-SETUP: See MC Setup................................................................................................................................................44MDL-COPY: See Model Copy............................................................................................................................................33MDL-NAME: See Model Name. ........................................................................................................................................15MDL-RES: See Model Reset. .............................................................................................................................................32MDL-SEL: See Model Selection.........................................................................................................................................14Meaning of Special Markings............................................................................................................................................47Mechanical ATL..................................................................................................................................................................50Menu Complexity: See Level Selection .............................................................................................................................12Menu Level: See Level Selection........................................................................................................................................12Menus: 3PK offers two separate menu types – the Direct Select menu which offers access to your 6 favorite functions withjust 2 buttons; all of the features of the radio in 3 levels of complexity (Level 1, 2, 3). ....................................................11Metal Gears: One or more drive gears within a servo that are made of one or multiple metal types. Metal gears tend towear more rapidly than nylon gears when in the same installation, and so require more frequent service to maintainoptimum accuracy; however, metal gears are more durable in the case of severe vibration, flutter, or physical shock.mHz (Megahertz = million cycles per second): The unit of radio frequency. 75 mHz are surface frequencies; 72 mHz areair frequencies; 27 mHz and 50 mHz can be used for either ground or air applications. Note: Use of the 50 mHz (ham radio)band requires an FCC license. The 3PK is not available on 50 mHz.Mix Mode: Option in programmable mixing. Selects whether slave moves exactly based upon the master channel’s controlmovement (unmixed) or the master channel’s servo movements after any mixing (mixed). In brake mixing, determineswhether front brakes respond based solely on trigger position (UNMIX), or whether other functions’ adjustments to rearbrakes also affect front brakes (MIXED). See Programmable Mixes. ................................................................................40Mixing: Allows a single input to control the operation of two or more servos that are plugged into separate channels.Simplifies more involved setups. For example, brake mixing, which utilizes 2 servos, one for front wheel braking and onefor rear wheel braking, allows different amounts of braking to front and rear when the driver simply gives brake with thetrigger. 3PK has 2 free programmable mixes which could be used to set up 4-wheel steering, separate front and rear steeringwith adjustable acumen, etc. See Programmable Mixes.......................................................................................................40MOD-MODE: Function used to select modulation for each separate model memory. ....................................................16MODE: Setting for this function at this time – typically inhibited or active.

Module: A removable/replaceable plug-in unit used in most complex computer radios, containing all frequency controlequipment, including the crystal and all tuned components. Changing channels or bands on a modular radio requires onlychanging module. Changing crystals WITHIN a module to change the channel of the module itself is against FCCregulation and is not recommended. To use your transmitter on a different channel you simply purchase another moduleon that other channel and the radio is now properly tuned and safe and easy to use on that other channel as well. The 3PKuses a new, specialized module, the PK, which can transmit not only in PPM and PCM but also HRS..............................7MXMD: Mix mode.
