Please observe the following safety precautions at all times. Explanation Of Symbols The parts of this manual indicated by the following symbols are extremely important and must be observed. Symbols Explanation Danger Indicates a procedure which could lead to a dangerous situation and may cause death or serious injury if ignored and not performed properly. Warning Caution Indicates procedures which may lead to dangerous situations and could cause death or serious injury as well as superficial injury and physical damage. Indicates procedures that may not cause serious injury, but could lead to physical damage. Symbols:

: Prohibited

: Mandatory 2.4GHz System Precautions Warning Special attention should be paid before turning on the system while other cars are running or oth-

er airplanes are flying because the 2.4GHz RC system could potentially affect them. Be sure to set the Fail Safe function. Receiver Mode Precautions Caution

:Futaba digital servo (including BLS Series brushless servos) When using the T4GRS in the T-FHSS (HIGH) and S-FHSS (HIGH) mode, always use it under the following conditions:

Servos Receivers battery :Matched to the ratings of the receiver and connected digital servo (dry cell battery cannot be used). Transmitter mode :RX MODE Under other conditions, the set will not operate, or the specified performance will not be displayed even if it operates. In addition, it may cause servo trouble. Futaba will not be responsible for damage, etc. caused by combination with the products of other companies. In addition, the FSU Fail Safe Unit cannot be used because the system is different. Use the fail safe function of the trans-

mitter. When using analog servos, always switch the T4GRS servo response to the "NORM" mode. Transmitter mode :"T-FHSS(NORM)", "T-FHSS(NORM)"and FHSS mode Receivers battery :Matched to the ratings of the receiver and connected servo (dry cell battery cannot be used). The set cannot operate in the "HIGH" mode. Operation in this mode will cause trouble with the servo and other equipment. Digital servos (including BLS Series brushless servos) can also be used in the "NORM" mode. 8 For Your Safety As Well As That Of Others Operation Precautions Warning Do not operate outdoors on rainy days, run through puddles of water or use when visibility is lim-

ited. Should any type of moisture (water or snow) enter any component of the system, erratic operation and loss of control may occur. Do not operate in the following places.

-Near other sites where other radio control activity may occur.

-Near people or roads.

-On any pond when passenger boats are present.

-Near high tension power lines or communication broadcasting antennas. Interference could cause loss of control. Improper installation of your Radio Control System in your model could result in serious injury. Do not operate this R/C system when you are tired, not feeling well or under the influence of alco-

hol or drugs. Your judgment is impaired and could result in a dangerous situation that may cause serious injury to yourself as well as others. Do not touch the engine, motor, speed control or any part of the model that will generate heat while the model is operating or immediately after its use. These parts may be very hot and can cause serious burns. Always perform an operating range check prior to use. Problems with the radio control system as well as improper installation in a model could cause loss of control.

(Simple range test method) Have a friend hold the model, or clamp it down or place it where the sticks or prop cannot come in contact with any ob-

ject. Walk away and check to see if the servos follow the movement of the controls on the transmitter. Should you notice any abnormal operation, do not operate the model. Also check to be sure the model memory matches the model in use. Turning on the power switches. Always check the throttle stick on the transmitter to be sure it is at the neutral position. 1. Turn on the transmitter power switch. 2. Turn on the receiver or speed control power switch. Turning off the power switches Always be sure the engine is not running or the motor is stopped. 1. Turn off the receiver or speed control power switch. 2. Then turn off the transmitter power switch. If the power switches are turned off in the opposite order, the model may unexpectedly run out of control and cause a very dangerous situation. When making adjustments to the model, do so with the engine not running or the motor discon-

nected. You may unexpectedly lose control and create a dangerous situation. Before running (cruising), check the fail safe function. Check Method; Before starting the engine, check the fail safe function as follows:

1) Turn on the transmitter and receiver power switches. 2) Wait at least one minute, then turn off the transmitter power switch. (The transmitter automatically transfers the fail safe data to the receiver every minute.) 3) Check if the fail safe function moves the servos to the preset position when reception fails. The fail safe function is a safety feature that minimizes set damage by moving the servos to a preset position when reception fails. However, if set to a dangerous position, it has the opposite effect. When the reverse function was used to change the operating direction of a servo, the fail safe function must be reset. Setting example: Throttle idle or brake position 9 For Your Safety As Well As That Of Others NiMH / NiCd / LiFe Battery Handling Precautions

(Only when NiMH/NiCd /LiFe batteries are used) Warning Never plug the charger into an outlet of other than the indicated voltage. Plugging the charger into the wrong outlet could result in an explosion or fire. Never insert or remove the charger while your hands are wet. You may get an electric shock. Do not use the T4GRS transmitter's battery, as the receiver's battery. Since the transmitter's battery has an overload protection circuit, the output power will be shut down when the high current load is applied. This may result in runaway or fatal crash. Always check to be sure your batteries have been charged prior to operating the model. Should the battery go dead while the model is operating, loss of control will occur and create a very dangerous situation. To recharge the transmitter battery, use the special charger made for this purpose. Overcharging could cause the battery to overheat, leak or explode. This may lead to fire, burns, loss of sight and many other types of injuries. Caution Do not use commercial AA size NiCd and NiMH batteries. Quick charging may cause the battery contacts to overheat and damage the battery holder. Do not short circuit the battery terminals. A short circuit across the battery terminals may cause abnormal heating, fire and burns. Do not drop the battery or expose it to strong shocks or vibrations. The battery may short circuit and overheat; electrolyte may leak out and cause burns or chemical damage. When the model is not being used, always remove or disconnect the battery. Leaving the battery connected could create a dangerous situation if someone accidentally turns on the receiver power switch. Loss of control could occur. Always keep the charger disconnected from the outlet while it is not in use. Storage And Disposal Precautions Warning Do not leave the radio system or models within the reach of small children. A small child may accidentally operate the system. This could cause a dangerous situation and injuries. NiCd batteries can be very dangerous when mishandled and cause chemical damage. Do not throw NiMH/NiCd/LiFe batteries into a fire. Do not expose batteries to extreme heat. Also do not disassemble or modify a battery pack. Overheating and breakage will cause the electrolyte to leak from the cells and cause skin burns, loss of sight, and other in-

juries. 10 For Your Safety As Well As That Of Others When the system will not be used for any length of time, store the system with NiMH/NiCd batteries in a discharged state. Be sure to recharge the batteries prior to the next time the system is used. If the batteries are repeatedly recharged in a slightly discharged state, the memory effect of the NiMH/NiCd battery may considerably reduce the capacity. A reduction in operating time will occur even when the batteries are charged for the rec-

ommended time. (After discharge to 1cell E.V.=1V) When the LiFe batteries will not be used for a long time, to prevent it from deteriorating we recom-

mend that it be kept in about the half capacity state instead of fully charged. Also be careful that the battery does not enter the over-discharged state due to self-discharge. Periodically (about every 3 months) charge the battery.

<NiMH/NiCd Battery Electrolyte>

The electrolyte in NiCd/NiMH batteries is a strong alkali. Should you get even the smallest amount of the electrolyte in your eyes, DO NOT RUB. Wash immediately with water, and seek medical attention at once. The electrolyte can cause blindness. If electrolyte comes in contact with your skin or clothes, wash with water immediately. Warning Do not store your R/C system in the following places.

- Where it is extremely hot or cold.

- Where the system will be exposed to direct sunlight.

- Where the humidity is high.

- Where vibration is prevalent.

- Where dust is prevalent.

- Where the system would be exposed to steam and condensation. Storing your R/C system under adverse conditions could cause deformation and numerous problems with operation. If the system will not be used for a long period of time, remove the batteries from the transmitter and model and store in a cool, dry place. If the batteries are left in the transmitter, electrolyte may leak and damage the transmitter. This applies to the model also. Remove the batteries from it also to prevent damage.

<NiMH/NiCd/Li-ion Battery Recycling>

A used battery is a valuable resource. Insulate the battery terminals and dispose of the battery by taking it to a battery recycling center. Other Precautions Caution Do not expose plastic parts to fuel, motor spray, waste oil or exhaust. The fuel, motor spray, waste oil and exhaust will penetrate and damage the plastic. Always use only genuine Futaba transmitters, receivers, servos, ESCs (electronic speed controls), NiMH/NiCd batteries and other optional accessories. Futaba will not be responsible for problems caused by the use of other than genuine Futaba parts. Use the parts specified in the instruction manual and catalog. Never use the R304SB-E in GP (Engine) models. Receiver R304SB-E can be used only with EP car. 11 For Your Safety As Well As That Of Others Before Using Features

-Telemetry system The T4GRS transmitter has adopted the newly developed bidirectional communication sys-

tem "T-FHSS"

-2.4GHzSS (Spread Spectrum) radio communication system Frequency channel setting is unnecessary: Channel shifting takes place within the 2.4GHz band automatically. This system minimizes the interference from other 2.4GHz systems.

-Model memory for 40 models Model names can use up to 10 letters, numbers, and symbols, so that logical names may be used. A model memory with different setups can be created by using the model copy func-

tion.

- Menu Selection The setup screens are called from menu screens. The menu screen can be selected from among 2 levels (LEVEL1/LEVEL2).

-Brake mixing for large cars (BRAKE) Brake mixing of the front and rear sticks of 1/5GP and other large cars can be adjusted inde-

pendently.

larity markings on the battery holder. Battery cover Battery Replacement Method 1 Remove the battery cover from the transmitter by sliding it in the direction of the arrow in the figure. 2 Remove the used batteries. 3 Load the new AA size batteries. Pay very close attention to the polarity markings and reinsert accordingly. 4 Slide the battery cover back onto the case. Slide battery cover while pressing here. Check:

Turn the power switch on the transmitter to the ON position. Check the battery voltage display on the LCD screen. If the voltage is low, check the batteries for in-

sufficient contact in the case or incorrect battery polarity. Disposal of the Dry Cell Batteries:

The method to dispose of used dry cell batteries depends on the area in which you reside. Dispose of the batteries in accordance with the regulations for your area. Caution Never try to recharge a dry cell battery. The transmitter may be damaged or the battery electrolyte may leak or the battery may break. Insert the batteries in the correct polarity. If the polarity is incorrect, the transmitter may be damaged. When the transmitter is not in use, remove the batteries. If the battery electrolyte leaks, wipe off the case and contacts. Do not use commercial AA size NiCd and NiMH batteries. Quick charging may cause the battery contacts to overheat and damage the battery holder. 16 Before Using When Using The Optional Battery When using an optional rechargeable battery, replace the battery as described below.

-Always use the optional HT5F1800B or FT2F1700BV2/2100BV2 rechargeable battery.

-The type of power source used must be set by system setting.

-When the transmitter will not be used for a long time, remove the battery. Battery Replacement Method 1 Refer to the previous description and remove the transmitter battery cover. 2 After removing the dry cell battery box from the transmitter, disconnect the connector. 3 Insert the connector of the new battery and load the new battery into the transmitter. 4 Finish by installing the battery cover. Caution When closing the battery cover, be careful that the battery cover does not pinch the battery lead wires. Shorting of the battery lead wires may lead to fire and abnormal heating and cause burns or fire disaster. HT5F1700B CAPACITY: 6.0VDC-1700mAh CHARGING: 170mA-12hours HT5F1700B CAPACITY: 6.0VDC-1700mAh CHARGING: 170mA-12hours 17 Before Using When Charging the Optional Battery Charging a NiMH Battery

(Example: When using the HT5F1800B with the special charger) 1 Plug the transmitter cord of the special charger in-

to the charging jack on the rear of the transmitter. 2 Plug the charger into an AC outlet. 3 Check that the charging LED lights. The charging time when charging the HT5F1800B battery with the optional special charger is approximately 15 hours. However, when the battery has not been used for some time, repeat charging 2 or 3 times to activate the battery. Over current protection The transmitter charging circuit is equipped with an over cur-

rent protection circuit (1.0A). If the battery is charged with a quick charger for other than digital proportional R/C sets, it may not be fully charged. Charging A LiFe Battery

(Example: When using the FT2F1700BV2/2100BV2 with the special charger) 1 Remove the battery cover. 2 Disconnect the battery from the 4GRS 3 Balance charging cannot be done through the transmitter, you must remove the LiFe battery to do this charge. AC outlet Charger Transmitter charging LED To receiver Ni-Cd battery To transmitter charging jack Charging jack Cannot be used for charge of LiFe. Charge the optional FT2F1700BV2/2100BV2

(LiFe) battery with the special charger in accor-

dance with the instruction manual supplied. When the battery will not be used for a long time, to prevent it from deteriorating we recommend that it be kept in about the half capacity state in-

stead of fully charged. Also be careful that the bat-

tery does not enter the over-discharged state due to self-discharge. Periodically (about every 3 months) charge the battery. Balance charging connector for LiFe battery charger. LiFe battery is removed from transmitter. 18 Before Using Warning Never plug it into an outlet other than the indicated voltage. Plugging the charger into the wrong outlet could result in an explosion or fire. Do not insert and remove the charger when your hands are wet. It may cause an electric shock. Always use the special charger or a quick charger for digital proportional R/C sets to charge a digital proportional R/C set NiMH battery. Overcharging a Ni-MH battery can result in burns, fire, injuries, or loss of sight due to overheating, breakage, or electro-

lyte leakage. Caution When the charger is not in use, disconnect it from the AC outlet. Do this to prevent accidents and to avoid overheating. Low Battery Alarm If the transmitter battery voltage drops below the usable range, an audible alarm will sound and "BATTERY LOW VOLTAGE" will be displayed on the LCD screen. If the battery goes dead while running (cruising), you will lose control of the vehicle (boat). Therefore, retrieve the vehicle (boat) im-

mediately and cease operation. Because the low battery alarm voltage of a dry cell battery is different from that of a rechargeable battery pack (genuine Futaba option), the type of power source used must be set by system setting. Warning When a low battery alarm is generated, cease operation immediately and retrieve the model. If the battery goes dead while in operation, you will lose control of the model. 19 Before Using Power & Display Switch The power switch and display switch of the T4GRS are inte-

grated. In the PWR ON mode, radio waves are transmitted and in the DISP mode, model data, settings can be checked without transmitting radio waves. In addition, some setting menus may only be displayed in the DISP mode. Power DISP Switch PWR ON Radio waves are being transmitted LCD screen UP MIDDLE OFF DOWN DISP Radio waves are not being transmitted When you do not run, turn OFF. LCD screen It cannot operate. Precautions when turning the power switch on and off.

- When the data is changed using the edit buttons or trim levers, wait at least two seconds before turning off the power. If the power is turned off within two seconds after the data is changed, the new data will not be writ-

ten to memory.

*If the throttle stick is not in the stop/idle position when the transmitter is switched "ON" an alarm will sound. Ensure that the throttle stick is in the stop/idle position when switching "ON" - if the alarm sounds the throttle output will default to stop/idle.

*The adjustment of the throttle range cannot be carried out if a ratchet is being used, only if the throttle stick is self-centering. 30 Before Using About Transmitter Antenna and Receiver About The Transmitter Antenna Position the antenna vertically to the ground. Antenna A B Antenna Moving Range Warning Position the antenna vertically to the ground. In other positions the operating range may be reduced. Never hold only the antenna. Hold the grip handle. Otherwise, the antenna may be damaged. The antenna position can be changed in the range as shown in figures A and B. However, please do not apply unnecessary force or shock. The internal cable may be damaged; thus transmitting distance is reduced and this may result in faulty operation. 31 Before Using Receiver Terminology Antenna Coaxial cable Link switch/LED Connectors

The operating range may reduced, depcompleted on where the receiver and the antenna are mounted. WARNING Do not cut or bundle the receiver antenna wire. Do not bend the coaxial cable. It causes damage. Install the antenna in the highest position possible as shown in the figure. Put the antenna in the antenna tube to protect it. Keep the antenna as far away from the motor, ESC and other noise sources as you possibly can. Wrap the receiver with something soft, such as foam rubber, to avoid vibration. If there is a chance of getting wet, put the receiver in a waterproof bag or balloon. Caution Antenna tube Antenna Coaxial cable R304SB

:Futaba all servo Transmitter mode setting Set the transmitter to the "T-FHSS(HIGH)" mode or "T-FHSS(NORM)" mode. Note: Only digital servos (including BLS Series Brushless servos) can be used in the T-FHSS(HIGH) mode. 32 Before Using Installation Receiver and Servo Connections Connect the receiver and servos as shown below. Connect and install the receiver and servos in accordance with "Installation Safety Precautions" on the next page. The figure shown below is an example. The method of connecting the motor controller to the motor and battery depends on the motor controller used. Purchase the motor con-

troller and servos separately. The receiver also depends on the set. Installation When An Electronic Speed Control Is Used Installation For Gas Powered Models CH4 CH1 B/C CH3 CH2 Receiver To Battery Switch CH4 servo CH3 servo Throttle servo Steering servo 33 Installation Installation Safety Precautions Warning Receiver (receiver antenna) Do not cut or bundle the receiver antenna wire. Do not bundle the receiver antenna wire together with the motor controller lead wire. Keep the receiver antenna wire at least 1cm away from motor, battery, and other wiring carrying heavy current. Install the receiver antenna holder as closely as possible to the receiver. If the antenna wire is cut, bundled, or routed near a noise source, the receiving sensitivity will drop, the running (sailing) range will decrease, and you may lose control of the model.

*Noise is transmitted through metal, carbon, and other conductive material, so keep the receiver antenna wire away from such parts. Antenna Battery

Install the receiver as far away as possible from the battery, motor controller, motor, silicon cord and other noise sources. Keep it away from the antenna wire, in particular. Receiver vibration-proofing / waterproofing

(Car) Vibration-proof the receiver by wrapping it in foam rubber or other vibration-absorbing material and mount it with thick double-sided tape. When using the receiver holder supplied with the model kit, mount the holder to the chassis through a rubber grommet. Vibration-proof the receiver by wrapping it in foam rubber or other vibration-absorbing material. Also waterproof the receiver by sealing it in a plastic bag. If the receiver is exposed to strong vibration and shock, or suffers from water leakage, reliable operation may be lost and you may lose control of the model.

(Boat) Foam rubber, etc. Mechanical plate Screw Damper Nut (as required) Wrap the receiver in foam rubber or oth-

er vibration-absorbing material. Do not use hard material. Hard material does not have a vibration-proofing effect. Receiver holder When using the receiver holder sup-

plied with the kit, install the receiver holder using rubber grommets to re-

duce vibration. Mechanical plate Thick double-

sided tape When mounting the receiver with double-sided tape, do not use a stiff tape. Stiff tape does not have a vibra-

tion-proofing effect. 34 Installation Warning Connector Connections Be sure the receiver, servo, battery and connectors are fully and firmly connected. If vibration from the model causes a connector to work loose while the model is in operation, you may lose control . Servo Installation When you install the servos, always use the rubber grommets provided in servo hardware bags. Mount the servos so they do not directly come in contact with the mount. If the servo case comes in direct contact with the mount, vibration will be directly transmitted to the servo. If this condition continues for a long time, the servo may be damaged and control will be lost. Screw Damper Eyelet Mechanical plate

(or) Nut (as required) When installing the servo, always install the accessory rubber grommet and grommet flush against the servo. A vibration-damping effect is not obtained if the rubber grommet and grommet are not in-

stalled correctly. Servo Throw Operate each servo over its full stroke and be sure the linkage does not bind or is loose. The continuous application of unreasonable force to a servo may cause damage and excessive battery drain. Caution!

A whining noise indicates that the steering servo is improperly set. Decide the EPA value at the contact point. Adjust the steering servo so that excessive force is not applied to the servo by the chas-

sis at maximum servo travel. Adjust the throttle servo so that excessive force is not applied when the engine carburetor is fully open, fully closed, and the brakes are applied fully. If the brakes overheat while running, their ability to function properly decreases. Before running, adjust the suitable maximum servo travel so that excessive force is not applied even when the servo travel is increased while running. 35 Installation Warning Electronic Speed Control Install the heat sinks where they will not come in contact with aluminum, carbon fiber or other parts that conduct electricity. If the FET Amp (Electronic speed control) heat sinks touch other materials that conduct electricity a short circuit could occur. This could result in loss of control and damage to the system. Motor Noise Suppression Always install capacitors to suppress noise when electric motors are used. If capacitors are not properly installed you could experience erratic operation and reduced range as well as loss of con-

trol. 1 2 3

"+" side

"-" side Schottky diode Motors with no suppressor capacitors, or inade-

quate suppression, may cause the receiver to mal-

function. Always solder the capacitors supplied to your motor. The Schottky diode improves the efficiency of the speed control / motor combination and provides extra protection to the brake FETs. The white ring must always face the positive side. Other Noise Suppression Methods Be sure there are no metal parts in your model which under vibration can come in contact with other metal parts. Metal to metal contacts under vibration will emit a high frequency noise that will affect the receiver's performance. You could experience erratic operation and reduced range as well as loss of control. 36 Installation Initial Set-Up Preparations (Transmitter) Before setting the Transmitter functions, check set the following items first.

(Display when power switch turned on) When the power switch is turned on, the currently selected model number is displayed. Check if this number is the model number you want to set-up. To change the model number, use the Model Select function. Turn on the transmitter power. The battery voltage is displayed. The model number is displayed.

(HOME screen) Receiver Type Check (RX MODE) This mode sets the RX type of the transmitter to match the receiver and servos used. The T4GRS transmitter uses the telemetry type T-FHSS ("TFH") system. It can also use the conventional FHSS and S-FHSS ("SFH") systems. Because the R304SB(-E) receiver supplied with the T4GRS uses the telemetry type T-FHSS ("TFH") system, its RX type must be set to the T-FHSS high speed mode ("TFH-HI") or the T-

FHSS normal mode ("TFH-NR"). Never use analog servos when the RX type was set to the T-FHSS ("TFH") 2.4GHZ system high speed mode "TFH-HI" or the S-FHSS (SFH) high speed mode "SFH-HI". The servos may be damaged. For example, if analog ser-

vos are used with a telemetry type T-FHSS receiver (R304SB, etc.), the RX type must be set to "TFH-NR", and if analog servos are used with an S-FHSS receiver (R2104GF, R204FG-E, etc.), the RX type must be set to S-FHSS ("SFH-NR") system normal mode or FHSS ("FHSS") system. When using digital servos (including BLS Series brushless servos), any RX type can be used. When a dedicated FHSS receiver (R603GF/R2004GF) is used, it will not operate if the RX type is not set to "FHSS". 37 Initial Set-Up If the receiver used and the RX type settings are different, change the RX type using the "RX MODE" function. Which RX type is set can be checked at the HOME screen.

ously memorizes the ID number of the receiver at the transmitter so that data from other receivers will not be received. The RX type setting and transmitter and receiver linking methods are described here. Refer to the figure at the right for the edit buttons used. 1 Set the transmitter power switch to DISP.

nae to touch) and turn on the receiver power. 4 Move the cursor to "LINK: EXE" by (JOG) button up or down operation. When the (JOG) button is pressed for approximately 1 second, "PUSH RX LINK SW" appears on the screen and 20 seconds countdown begins. Countdown can be can-

celled at any time using button up down or left right operation. 5 During 20 seconds countdown, R304SB press the receiver link switch for approximately 2 seconds. The LED will begin to blink red. After the receiver LED switches from blinking red to green-red steady light, the T4GRS generates an electronic beeping sound, and "LINK:OK" and "COMPLETE!" ap-

pear on the screen, reading of the mutual IDs ends and the memorized receiver ID num-

ber appears on the T4GRS screen. If an error screen was displayed, linking failed. Retry linking. If the transmitter and re-

ceiver are linked normally, set the power switch to the OFF position and then return it to the PWR ON position. If the receiver LED lights green, linking was successful. Check for correct servo operation.

(Error screen)

*The T4GRS and a telemetry type T-FHSS receiver (R304SB, etc.) mutually memorize the combined ID linked last at each model memory. Since the T4GRS can memorize only 1 receiver ID at each model memory, multiple T-

FHSS receivers cannot be used with the same model memory. If the same model mem-

ory is used for more than one model it will be necessary to re-link the receivers each time a different model is operated. When using multiple telemetry type T-FHSS receivers, link and combine them with each T4GRS model memory. Note however that, multiple receivers cannot be linked to multiple model memories. The telemetry function communications status can be checked at the T4GRS HOME screen. 39 Initial Set-Up The telemetry ON/OFF and communication status can be checked at the HOME screen.

Receivers Other Than T-FHSS 1 Bring the transmitter and the receiver close to each other, within 20 inches (half meter). 2 Turn on the transmitter. 3 Turn on the receiver. 4 Push the link switch of the receiver. ON UP When the link is complete, the LED in the receiver changes to solid green. Precaution:

If there are many Futaba 2.4GHz systems (T-FHSS/ S-FHSS/ FHSS) turned on in close proximity to your re-

ceiver then it might not link to your transmitter. In this case, even if the receivers LED stays solid green, unfor-

tunately the receiver might have established a link to one of other transmitters. This is very dangerous if you do not notice this situation. In order to avoid the problem, we strongly recommend you to double-check whether your receiver is really under control by your transmitter by giving the stick input and then checking the servo response.

*Please refer to the table below for LED status vs receiver's condition. LED status vs receivers condition:

- Correct the maximum steering angle for left and right steering angles when there is a difference in the turning radius due to the characteristics, etc. of the vehicle. Maximum steering angle The EPA function basically determines the maximum steering angle of each channel. The functions shown below may have been adjusted or the operating range set by EPA function may be exceeded. Check the linkage each time the following functions are adjusted.

- Sub trim (all channels).................................. P53

- Program mixing slave side (all channels) .....P78

- Idle up (throttle) ............................................P89

- Throttle off, Engine cut (throttle).................. P91

- Throttle acceration (throttle).........................P65 ATL trim ATL trim allows adjustment of the brake side operation amount during operation. Therefore, when the operating angle is adjusted with throttle EPA, ATL trim must also be taken into account. Warning Operate each servo over its full stroke and be sure the linkage does not bind or is not loose. The continuous application of excessive force to a servo may cause damage and excessive battery drain. F u n c t i o n Caution!

A whining noise indicates that the steering servo is improperly set. Decide the EPA value at the contact point. Adjust the steering servo so that excessive force is not applied to the servo by the chas-

sis at maximum servo travel. Adjust the throttle servo so that excessive force is not applied when the engine carburetor is fully open, fully closed, and the brakes are applied fully. If the brakes overheat while running, their ability to function properly decreases. Before running, adjust the suitable maximum servo travel so that excessive force is not applied even when the servo travel is increased while running. 54 End Point Adjuster "END POINT"

(All channel) Fail Safe Function "FAIL SAFE"

Fail Safe Mode (F/S) This function moves each servo to a preset position when the receiver does not receive a clear signal from the transmitter.

-When the condition set at "FHSS" is Rx type, fail safe (F/S) can be set only for throttle (TH). Other channels are set to the normal mode.

-The fail safe data is transferred from the transmitter to the receiver 10 seconds after the transmitter power is turned on. The

-

ceiver power is turned on next and the data is transferred for approximately 10 seconds after the receiver power is turned on.

-For gasoline engine cars, for safety we recommend that this fail safe function be used to set the throttle channel in the direc-

tion in which the brakes are applied. Hold mode (HOLD) This function holds the servo/s at the position they were in immediately before recep-

tion was lost. This applies to the T-FHSS type (R304SB...,etc.) and the S-FHSS type

(R2104GF...,etc.) receivers only. When the receiver used is an R603GF/2004GF or other FHSS type, this function is not available. Off mode (OFF) In this model the receiver stops outputting a signal to the servos if the transmitter signal is lost. The servos become effectively unpowered. The F/S, HOLD, and OFF modes are automatically reset when signals from the trans-

mitter can be received again. Battery fail safe function (BFS) If the receiver battery voltage drops below a certain value when this function is enabled, the throttle servo moves to the position set by fail safe function. When the battery volt-

age recovers, the battery fail safe function is automatically reset.

-This function cannot be used when the throttle (TH) is not set to fail safe (F/S).

-This function is for the T-FHSS type (R304SB...,etc.) and the S-FHSS type (R2104GF...,etc.) receiver only. It cannot be used with the R603GF and R2004FG and other FHSS type. Display to "FAIL SAFE" screen by the following method:

FWRD BRAKE Set value The standard value (100% point) of this setup affects the operation amount set by throttle EPA function. Convenient usage method For GP cars, the linkage must have a clearance because one servo controls the engine carbure-

tor and brake. Thus, there is a noticeable time delay at both the forward and brake sides. Sharp response comparable to that of electric motor cars is obtained by reducing this clearance at the trans-

mitter side. Display to "TH ACCEL" screen by the following method:

This is a function select switch dial function. The idle up switch must be set. This function is used to improve engine starting performance by raising the idling speed when starting the engine of a gasoline car (boat). It is also effective when you want to eliminate any braking effect when the power is turned off during running, due to the effect of your gear ratio setting and choice of motor when operating an electric car. However, considering safety, and to prevent the motor from rotating instantly when the power was turned on, the MC950CR, MC851C, MC602C, MC402CR, and other Futaba MC (Motor Controllers) will not enter the operation mode if the neutral position is not confirmed. When using the MC950CR, MC851C, MC602C, MC402CR, or other Futaba MC, confirm that the MC is in the neutral position and the set is in the operation mode before setting the idle up function switch to ON. Operation The throttle neutral position is offset to the forward side. There is no linkage locking, etc. because there is no change near the maximum operation angle even when the neu-

tral position is offset by this function. Operation Display While this function is ON, the LED blinks.

91 Function ESC Link Function "MC LINK"

This is a special function which lets you set the contents of the Link software in Futaba speed controller (ESC), MC960CR, MC940CR, MC950CR, MC851C, MC602C, MC402CR, etc, with variable frequency and other data changes at the T4GRS transmitter. However, some data changes require a PC and Link software. This function is used by connecting ESC directly to the transmitter. The T4GRS power switch is set to the display side. Use the various optional servo extension cords according to the distance between the transmitter and ESC. The last data read from ESC to T4GRS or the last data written from T4GRS to ESC is saved to the T4GRS. Since the data for each model memory can be saved, the data of up to 40 models can be saved.

-When the T4GRS battery voltage drops, the display switches to low battery display. Therefore, use this function when there is ample battery capacity remaining.

-Also connect the battery at the ESC side.

Same as Link software Neutral Brake. Use this setting when you want to use the brakes at the neutral throttle (OFF) position by throttle operation. The larger this value, the greater the braking force. When you want to use the neutral brake, set this value to "0%". CLM-(CURRENT LIMIT) 50A~300A (MC950CR:50A~300A), OFF Same as Link software Current Limiter. Current Limiter sets the current value at maximum load here. Since setting of the MAX is based on the output current limit value set by Current Limiter, Current Limiter does not have to be turned OFF except when a current exceeding 300A is generated.

"MIn" which sets the frequency when the load is small, is set to the high frequency side (large value) when extension is desired after straight-

away and curves.

"MAX" which sets the frequency when the load is large, is set to the high frequency side (large value) when you want to suppress the rise from low speed and when motor heating and commutator roughness are sensed. When the rise from low speed is poor, and becomes bad even when "MAX" is set to the low frequency side, use the log data to check if there was a momentary voltage drop. When you want to suppress the overall power, lengthen the run time, and otherwise improve efficiency, set both "MAX" and "MIn" to the high frequency side. When you want to set a fixed PWM frequency at full range regardless of the load current, set PWM frequency (at Max. load) and PWM frequency (at Min. load) to the same value. 94 ESC Link Function "MC LNK"

Function LBP-(LOW BATTERY VOLT) 2.5V~6V 2.5V~7.5V for MC950CR Same as Link software Low Bat Protection This setting cuts off the output to the motor when the main battery voltage drops to the set voltage. This stops the receiver ceasing operation when the power to the receiver becomes insufficient whilst running due to a drop in the power supply voltage. When the power supply voltage recovers, power is supplied to the motor once more. DBA-(DEAD BAND) 2s~50s Same as Link software Dead Band. This sets the range (neutral point range) over which the ESC does not respond to transmitter throttle operation. The larger the set value, the wider this range. Position at which motor starts to run Dead Band Throttle neutral position Point at which brakes start taking effect CTM-(C.L. TIME LIMIT) 50A~300A /CLT-(C.L. TIMER) 0sec(OFF)~240sec

This is effective in preventing the motor from outputting wasted energy when the voltage is high immediately after the power battery was recharged.

- "CTM" (Time Limit) sets the maximum output current for the time the output current is limited.

- "CLT" sets the time the output current is limited. This function is disabled when set to "0" sec. Since the Current Limit Timer starts when the throttle stick is pushed forward and current is output to the motor, this function begins to operate when the motor is run during trim adjustment, etc. FWB-(FORWARD BOOST) 0~100 (except MC850C) Same as Link software Forward Boost Operation near the throttle stick (stick) neutral position becomes a sharp increase.

When the rise from low speed is poor, and becomes bad even when "MAX" is set to the low frequency side, use the log data to check if there was a momentary voltage drop. When you want to suppress the overall power, lengthen the run time, and otherwise improve efficiency, set both "MAX" and "MIn" to the high frequency side. When you want to set a fixed PWM frequency at full range regardless of the load current, set PWM frequency (at Max. load) and PWM frequency (at Min. load) to the same value. LBP-(LOW BATTERY VOLT) 2.5V~7.5V Same as Link software Low Bat Protection This setting cuts off the output to the motor when the main battery voltage drops to the set voltage. This stops the receiver ceasing operation when the power to the receiver becomes insufficient whilst running due to a drop in the power supply voltage. When the power supply voltage recovers, power is supplied to the motor once more. DBA-(DEAD BAND) 2s~50s Same as Link software Dead Band. This sets the range (neutral point range) over which the ESC does not respond to transmitter throttle operation. The larger the set value, the wider this range. Position at which motor starts to run Dead Band Throttle neutral position Point at which brakes start taking effect Page1 REV-(REV CANCEL) BRk /REV Same as Link software Reverse Cancel. When set to BRk, reverse operation is disabled. BMD-(BRAKE MAX DUTY) 0%~100%

Same as Link software Brake Max. Duty. This setting can set the braking force between the neutral point and Max brake point. The larger this value, the greater the braking force. When set to "0%", the brakes are disabled. RMD-(REVERSE MAX DUTY) w/back only 0%~100%

Same as Link software Reverse Max. Duty This setting can set the reverse power between the neutral point and Max reverse point. The larger this value, the greater the reverse power. When set to "0%", reverse is disabled. 100

gine braking in full sized vehicles. BEC-(BEC VOLT) 6.0V / 7.4V Same as Link software BEC Volt. The receiver BEC voltage can be selected from 6.0V and 7.4V. Match the voltage to the rating of the servo connect-

ed to the same receiver. This BEC voltage cannot output a voltage higher than the input voltage. Page1 ESC Link Function "MC LNK"

97 Function Page1 TBM-(TURBO MODE) OFF /LV1 /LV2 Same as Link software Turbo Mode This function sets the turbo mode. More power can be enabled using the turbo mode. Depcompleted on the setting, the motor and ESC may be damaged so use this setting carefully.

(Note) When LAU (LEAD ANGLE USE) is off, lead angle setting will not operate even if set to LEV1 or LEV2.

(Turbo mode disabled, TBM=OFF) OFF mode: (No Lead Angle mode) Lead angle - No When used in races in which the lead angle setting function is inhibited by ESC, set to this mode. The lead angle function is disabled in the same manner as if LAU (LEAD ANGLE USE) was turned off. When the lead angle function is disabled by the method described above, the MC960CR shows that the lead angle function is off by flashing a blue LED at an ON 0.1 second, OFF 0.9 second cycle at the neutral point. LV1 turbo mode: (Lead Angle mode) Lead angle Yes The output can be increased by setting a lead angle. Depcompleted on the set value, the motor may be damaged so increase the lead angle value in steps from a small value while observing the result. Turn on LAU (Lead Angle Use) and adjust the lead angle by LA-(LEAD ANGLE) and A, B, C, D, E BA-(A, B, C, D, E BOOST ANGLE) value. LV2 power mode: (Power Mode) Lead angle Yes Displays still more power than a turbo. However, since even a motor applies a large load on the ESC, make the lead angle larger in steps from a small value while observing the result. Turn on LAU (LEAD ANGLE USE) and adjust the lead angle by LA-(LEAD ANGLE) and A, B, C, D, E BA-(A, B, C, D, E BOOST ANGLE) value. When "LAU" (LEAD ANGLE USE) is turned on "LA" (LEAD ANGLE) is the lead angle can be set. In addition, the "BOOST ANGLE" and "BOOST ANGLE RPM" can be set.

The lead angle can be set up to 59 degrees in 1 degree increments. A,B,C,D,E BA-(A,B,C,D,E BOOST ANGLE) 0~59 deg Same as Link software Boost Angle A,B,C,D,E RPM-(A,B,C,D,E BOOST ANGLE RPM) 0~99990 rpm Same as Link software Boost Angle rpm When LAU (LEAD ANGLE USE) is turned on the lead angle versus motor speed of the 5 points A to E can be set. The lead angle can be set up to 59 degrees in 1 degree increments. Note: Do not read to the T4GRS an MC940/960CR whose speed was set to over 99990rpm by Link software side Boost Angle rpm setting. Page2 The LA-(LEAD ANGLE) and A, B, C, D, E BA- (A, B, C, D, E BOOST ANGLE) relationship is shown on the graphs below. Graph [A] shows the relationship when the same value is set at points A, B, C, D, E BA-

(A, B, C, D, E BOOST ANGLE) of [A] and [B] and the LA-(LEAD ANGLE) was set to "0" and graph [B]

shows the relationship when a value other than "0" was set at LA-(LEAD ANGLE). As shown in the graphs, [B] is added to the A, B, C, D, E BA-(A, B, C, D, E BOOST ANGLE) set lead an-

gle and [A] is added to the LA-(LEAD ANGLE) set lead angle. For example, if "3" is set at ABA and LA of [B]

is set to "2", the actual ABA becomes 3+2=5 (deg). Since LA of [A] is "0", the actual ABA also becomes 3+0=3 (deg).

"OFF", the lead angle setting function can be turned off even if TBM is set to "LV1" or "LV2". The MC940,960CR shows that the lead angle setting function is OFF ("0" timing) by flashing an LED. ESC Link Function "MC LNK"

99 Function Data Transfer "MDL TRANS"

This function copies the model memory data of one T4GRS to another T4GRS. Con-

nect the communication port of both T4GRS together with the optional DSC cord for T4PK. Use this function with the T4GRS power switch set to the display side. Note: If the T4GRS battery voltage drops, the display switches to low battery display. Therefore, use this function when there is ample battery capacity remaining. Note: Since the receiving side writes the new contents of the currently selected model memory, always check the model number before executing this function.

Function(HOME screen)

*The telemetry function is compatible with only the T-FHSS system.

*The telemetry function requires a corresponding receiver (R304SB,R304SB-E).

*Only T4GRS with R304SB(-E) ID registered have a telemetry display.

*Multiple sensors of the same type cannot be used. Telemetry "TELEMETRY"

With the telemetry system, the running status can be displayed at the transmitter and also recorded as a data log by mounting various sensor units to the chassis. The telemetry related screens are only displayed when the T4GRS power switch is in the PWR ON position. When the power switch is in the DISP position, the telemetry related screens are not displayed. The T4GRS displays four kinds of information on the HOME screen;

receiver power source (battery) voltage, external power supply (drive bat-

tery) voltage, speed, and temperature. The sensor data can be checked at the transmitter by connecting the telemetry sensor sold separately to the S.BUS2 connector of the R304SB(-E) receiver. The figure is an example of connection of a telemetry sensor. The data of up to the fol-

lowing 3 types of sensors and the receiver power supply voltage can be transmitted by using the 3-way extension cord or double extension cord sold separately. The receiver power supply can also be connected to the S-BUS2 connector or each of CH1-4. A receiver power supply voltage sensor is unnecessary.

*The S-BUS2 system exerts control by connecting multiple gyros, servos and other devices corresponding to one S-BUS2 connector. Each device is separately controlled by setting the channel No. or slot No. individually for each device. A slot No. is also set for telemetry sensors. With the T4GRS system, each slot No. of a telemetry sensor must be set to its ini-

tial value. Since the slot No. can be changed for other aircraft type transmitters (T18MZ, etc.), sensors with changed slot No. will not operate if not returned to their initial slot No. When using a sensor that is used with transmitters other than a T4GRS, whether or not the slot No. is set to the initial value given in the sensor instruction manual must be checked at the changed transmitter (T18MZ, etc.). With the T4GRS, the set slot No. cannot be checked or changed. So, essentially, if a sensor has been used in an 18MZ, and you want to use the same sensor with your T4GRS, you must first change the slot number through the 18MZ or it will not work in your T4GRS.

The interval at which the data is acquired can be selected from a minimum 0.1 second to a maximum 60 seconds. Because the maximum count is 200, if the count is made 200 counts at 0.1 second intervals, 20 seconds worth of data is acquired, and if the count is made 200 counts at 60 second intervals, 3 hours 20 minutes worth of data is acquired. Data logging is started and stopped by setting SW1 set by SW/Dial function to "LOG-
