Display the MC LINK function screen in the above manner.Using the ESC Link functionESC 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.-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.ESC Link Function "MC LNK"2 (ESC read)Execute this function to read the connected ESC type and the data currently set at the amp.

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

95FunctionLBP-(LOW BATTERY VOLT) 2.5V~6V2.5V~7.5V for MC950CRSame as Link software Low Bat ProtectionThis 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.100500%Brake (Reverse) operationBraking forceReverse PowerBMD-(BRAKE MAX DUTY) 0%~100% Same as Link software Brake Max.

98FunctionPage1TBM-(TURBO MODE) OFF /LV1 /LV2Same as Link software Turbo ModeThis 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 - NoWhen 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 – YesThe 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 – YesDisplays 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.

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.Page2When 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 LED.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).RPM(A) RPM(B) RPM(C) RPM(D) RPM(E)AnG(A)AnG(B)AnG(C)AnG(D)AnG(E)RPM(A) RPM(B) RPM(C) RPM(D) RPM(E)AnG(A)LAAnG(B)AnG(C)AnG(D)AnG(E)B (LA >"0")A (LA ="0") Lead Angle(deg) Lead Angle(deg)rpmrpmESC Link Function "MC LNK"

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 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.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 gure 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 rst change the slot number through the 18MZ or it will not work in your T4GRS.

Since the data is sequentially updated, when data logging is performed, the old data is erased. Only 1 data is saved.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-GER" and by switch (SW1). If the switch (SW1) is not set, data logging is started by throttle stick from the log setting screen.Data logging can also be started by throttle stick from this screen and stopped by switch (SW1) set by SW/dial function.Refer to the map on page 116 for the log setting (LOG MODE) screen display.(Preparation)When using a switch (SW1) to start and stop data logging, set SW1 to "LOGGER" by SW/dial function.- On the HOME screen, open the LOG MODE screen by pressing the (-) button.1 (Log function ON/OFF)Move the cursor to the "MODE" setting item using (JOG) button up or down operation, and turn on the log function by setting "MODE" to "ACT" by pressing the (+) button or (-) button.
