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 object. 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.

For Your Safety As Well As That Of Others

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

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.

For Your Safety As Well As That Of Others

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 injuries.

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 recommended time. (After discharge to 1cell E.V.=1V)

When the LiFe batteri



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.

will not be used for a long time, to prevent it from deteriorating we recom-

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.

For Your Safety As Well As That Of Others

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.

Before Using

Features

-Telemetry system

The T4GRS transmitter has adopted the newly developed bidirectional communication system "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.

Before Using

-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 function.

- 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 independently.

-4WS mixing for crawlers and other 4WS type (4WS)

-Gyro mixing (GYRO MIX)

The sensitivity of Futaba car rate gyros can be adjusted from the T4GRS.

-CPS-1 mixing (CPS MIX)

LED lighting and ashing control using our CPS-1 channel power switch can be matched to

steering and throttle operation by switch only.

-Anti-skid braking system (TH A.B.S)

This function applies the brakes so that the tires of gasoline engine cars, etc. do not lose their grip on the road even when braking at corners.

-Throttle acceleration (ACCEL)

Gasoline engine cars have a time lag before the clutch and brakes become effective. The throttle acceleration function reduces this time lag.

-Throttle speed (SPEED)

Sudden stick operation on a slippery road surface will only cause the tires to spin and the model to not accelerate smoothly. By setting the throttle speed function, operation can be performed smoothly and easily. It also suppresses battery consumption.

-Steering speed (SPEED)

When you sense that the steering servo is too fast, etc., the servo operating speed (direction that suppresses the maximum speed) can be adjusted.

-Racing timer (TIMER)

The lap timer can record 100 lap times and total time. The timer can also be started automatically by stick operation. The race time and audible alarm can be set. Re-/fueling time are indicated by an audible alarm. An up timer is also provided.

-Digital trim

The current trim position is displayed on the LCD screen. The operating amount of 1 step can also be adjusted. Trim operation has no effect on the maximum travel of the steering and throttle servos.

-Function select switch / dial function (TRIM DIAL)

This function assigns functions to 2 switches and dials (digital trim, digital dial). The step amount and operating direction can also be adjusted. Trim positioning at each model call is unnecessary because all the dials are digital.

Before Using

-ESC-Link function (MC-LINK)

This is a dedicated function which allows setting of the contents of the Link software which makes possible Futaba speed controller (ESC), MC950CR, MC850C, MC851C, MC602C, MC402CR, etc. variable frequency and other data changes by T4GRS.

Charging jack

Cannot be used for charge of LiFe.

Charge the o ption al F T2F1700BV2/2100BV2 (LiFe) battery with the special charger in accordance 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 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.

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 electrolyte leakage.

Caution

When the charger is not in use, disconnect it from the AC outlet.



Do this to prevent accidents and to avoid overheating.

Before Using

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.

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".

Receiver Type Change & How To Link

The rst operation described below sets the RX type. Next, the transmitter and receiver

are linked and the transmitter ID number is memorized at the receiver so that signals

from other transmitters will not be received. The telemetry type T-FHSS also simultane

ously memorizes the ID number of the receiver at the transmitter so that data from other

receivers will not be received.

During 20 seconds countdown,

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!" appear on the screen, reading of the mutual IDs ends and the memorized receiver ID number appears on the T4GRS screen. If an error screen was displayed, linking failed. Retry linking. If the transmitter and receiver 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.

R304SB

(Error screen)

Initial Set-Up

*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 TFHSS receivers cannot be used with the same model memory. If the same model memory is used for more than one model it will be necessary to re-link the receiver’s 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.

The telemetry ON/OFF and communication status can be checked at the HOME screen.

Receivers Other Than T-FHSS

Bring the transmitter and the receiver close to each other,

within 20 inches (half meter).

Turn on the transmitter.

Initial Set-Up

Turn on the receiver.

Push the link switch of the receiver.

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 receiver then it might not link to your transmitter. In this case, even if the receiver’s 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 receiver’s condition:

No signal reception Red : On Receiving signals Green: On Receiving signals, but ID is unmatched. Green: Blink Unrecoverable failure (EEPROM,etc.) LED: Red and Green turn on alternately

*1: LED could be change to red intermittently during data processing.

(Set-Up Procedure When Installed In a Car)

When installing the servos in a car, performing function set-up in the following order is

recommended.

Carry out the Trims Initial Set-up as described on the previous page.

Set the servo direction of operation using the Reverse function.

- The servo installation method and linkage direction depend on the kit. Therefore, the servo operation direction may have to be reversed relative to transmitter operation. Before installing the servo, check the operating direction and set it using the Reverse function.

Set the subtrim and adjust the servo neutral point.

Set the throttle stick travel by adjusting the throttle stick mechanical ATL

to your liking.

- When the throttle stick travel is changed, set the servo travel as required using the adjuster

function.

Set EPA of each channel and adjust the servo throw (travel).

Fail Safe Function "FAIL SAFE"

(All channel)

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 data is transferred every 5 seconds after that. Be careful because normally the transmitter power is turned on rst and the receiver 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 direction in which the brakes are applied.

Hold mode (HOLD)

This function holds the servo/s at the position they were in immediately before reception 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.

Speed)

Sudden throttle stick operation on a slippery surface will cause the wheels to spin, resulting in poor acceleration. Setting the throttle speed function reduces wasteful battery consumption while at the same time enabling smooth, enjoy

able operation.

Operation

-Throttle servo (ESC) operation is slowed when the throttle stick is pushed forward so that the wheels will not spin even if the throttle is opened faster than required.

This function is not active when the stick is pulled back for brake/reverse.

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 carburetor 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

When the brakes are applied while cornering with a 4 Wheel Drive or other type of vehicle, understeer may occur. This under steer can be eliminated and cornering improved using this function.

Operation

- When the brakes are applied, the throttle servo will pulse intermittently. This will have the same effect as pumping the brakes in a full size car.

- The brake return amount, delay amount, pulse cycle, and brake duty can be adjusted.

Fail Safe Unit

When the T4GRS is used with the Futaba fail safe unit (FSU), it will operate as described below. However, FSU-1 cannot be used in the high speed mode.

- When the FSU is connected to the throttle channel, and the A.B.S. function has been

activated, the FSU LED will ash each time the servo operates. The reason for this is

that the FSU responds to sudden data changes caused by A.B.S. function pumping op eration. It does not mean that the fail safe function is activated. The servo will not be affected.

MIn-(PWM FREC MIN LD) 100Hz~10000Hz (10kHz) MC950CR:500Hz~30000Hz (30kHz)

Same as Link software PWM frequency (at Min. load), MIn sets the "0"A PWM frequency at minimum load.

MAX-(PWM FREC MAX LD) 100Hz~10000Hz (10kHz) MC950CR:500Hz~30000Hz (30kHz)

Same as Link software PWM frequency (at Max. load). MAX sets the PWM frequency at maximum load at the output cur-

rent limit value set by Current Limiter.

BRK-(PWM FREC BRK LD) nOR(2000Hz)/ HIG(1000Hz)/ SPH(500Hz)

MC950CR:500Hz~30000Hz (30kHz)

Same as Link software Brake PWM at frequency. This setting can set the brake PWM frequency.

nTB-(NEUTRAL BRAKE) 0%(OFF)~100%

Same as Link software Neutral Brake.

Function

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 straightaway 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.

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~6V

100

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.

CTM-(C.L. TIME LIMIT) 50A~300A /CLT-(C.L. TIMER) 0sec(OFF)~240sec

(except MC950CR)

Same as Link software Current Limiter (Time Limit)/Current Limit timer. The output current can be limited up to a set time from the start of running.

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.

DBA-(DEAD BAND) ±2μs~±50μs

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.

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 not effective.

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 not effective.

MC950CR only setup item

REV-(REV CANCEL) BRk /REV Same as Link software Reverse Cancel.

When set to BRk, reverse operation is disabled. LA-(LEAD ANGLE) 0~1500 Same as Link software Lead Angle.

The lead angle of the motor can be set at the MC950CR side. However, we recommend that it is normally "0". Since this setting is based setting by referring to the speed log by the Link software, independent use of the MC LINK function of the T4GRS is recommended.

larger this value, the greater the braking force. When you want to use neutral brake, set this value to "0%".

CLM-(CURRENT LIMIT) 50A~500A

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.

aways and curves.

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

TBM-(TURBO MODE)

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 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.

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).

B (LA >"0")A (LA ="0") Lead Angle(deg) Lead Angle(deg)

When using in races in which the lead angle setting function is inhibited by the ESC, set LAU (LEAD

ANGLE USE) to OFF. The LAU setting has priority over TBM-(TURBO MODE). If LAU is set to

"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
