How to connect

Use double-sided tape to fix the ESC in safe area.
Pay close attention to the polarity (+ and-) when connecting the battery cable. If you make a mistake between + and-when connecting to the battery, the ESC will be damaged. In addition, please note that the failure caused by this operation is not covered by the warranty. Use BEC wire to connect the receiver to the ESC’s 3-pin port. (Do not mistake + and-)
Solder 3 motor wires to ESC before connecting to the motor. At that time, connect A-B-C wires of ESC and A-B-C of the motor that match. When using solder, do not apply solder for more than 5 seconds as it will become hot and may damage the ESC. Damage during solder installation is not covered by the warranty, so be careful when working. After installing the solder, be careful that the wires are not in contact with each other. If the wires are in contact with each other and short-circuited, the product will be damaged and the warranty will be invalid
Connect the sensor cable to the ESC and motor.
Connect the receiver cable to CH2 of the receiver..
- The output voltage of the FAN port is designed to be the same as the battery voltage.
- A-B-C connected to the motor can be changed to C-B-A by changing the programming card settings.

Default Settings

Initial setting value of the transmitter: (After setting the transmitter as follows, perform the initial setup of the amplifier)

Throttle Level	100％
Brake Level	100％
Throttle EXP	0%
Throttle Neutral Trim	0
Throttle Servo Reverse	Reverse (Futaba,KO, Sanwa)

Common to RPX 3 and RPX S
Connect the charged battery to the ESC. (Be careful on polarity)

For safety, avoid tyres touching the ground to prevent the car from moving.

Turn on the transmitter.
Hold the throttle trigger of the transmitter at full brake side.
Turn on the power while holding the throttle on brake side.
Red LED blinks twice to enter the setup.
After red LED blinked twice, if the throttle trigger is held to full throttle, red LED will blink twice.
Return the throttle trigger to neutral position and when red LED lights up, the setting is completed.

If the initial setting cannot be made, change the throttle of the transmitter from the reverse setting to the normal setting, and then set the amplifier again.
Some transmitter manufacturers have a high response mode setting. Depending on the transmitter manufacturer, the initial setting may not be possible, so set the ESC with the normal mode of the transmitter.

Changing ESC Settings

ESC settings are available to change regarding on use of each categories. An optional program box is required to change each setting.
Connect attached wire to the program box.
Connect program box to the program port of the ESC main unit.
Connect ESC and battery. When ESC is turned on, program box will start automatically.“ Loading…” is displayed on the screen and ESC setting program box will be read. When reading the programming is completed, “YOKOMO” and “Program” are displayed on the screen, and ESC setting will be able to change, and programming can be changed easily.
A-B-C wires connected to the motor can be changed to C-B-A by changing the initial settings of the programming card.

- Press“ Enter” to enter program mode or read data. It is divided into 8 modes.
- If you encounter any problems, please initialize the program box and then check the ESC settings.
- Change settings with the four buttons located below the program box. The function of each button differs
- depending on the screen display. “Select” button —– Move to next item, and hold down “Select” button for 2 seconds ——- Return to the previous item.
- “▲” button ̶̶ Scrolls up.
- “▼” button-Scrolls down.
- “Enter” button –The changed data will be sent to ESC and rewritten with new data.
- If program box and ESC settings are same, no data will be sent. “Send Sucessed” is displayed after data transmission only when there is a change in the set value. If you have any doubts about the settings, you can return to the default settings and then change the settings again.
Update
- ESC firmware rewrite
- Go to the“ Update” menu and press“ Enter” to see the current ESC firmware. Press“ Enter” again to access the firmware folder on the SD card. Select the firmware to use for updating ESC and press“ Enter” again to start the update. The update will take about 1 minute.

[A.POWAER SETTING]

1 PWM Frequency| Drive frequency can be adjusted. At 2K, feeling of power at low speeds increases, and at 32K, feeling

of power at high speeds increases.

2 Punch| If you set it to 30, you can get the maximum punch when moving forward.
3 Compress| You can adjust the throttle curve. 0% is a linear slot.
4 Throtte Feel| Adjust throttle response. 5 is an aggressive throttle.
5 Max Reerse Force| You can adjust the maximum speed when moving backward.
[B.Brake Setting]
1 Drag Brake| Automatic brake adjustment when the transmitter throttle is in neutral. 30% is the maximum brake value.
2 Brake Punch| You can adjust the punch when braking. The maximum brake punch is 30%.
3 Initia Brake| You can adjust the eﬀectiveness of the initial brake when operating the brake.
4 Brake Frequency| Smooth braking can be obtained by adjusting the brake frequency and increasing the frequency.
5 Max Breke Force| Throttle operation, maximum brake eﬀectiveness adjustment.
[C.Timing Setting]
1 Boost Timing Activation| When you set the boost, you can select the automatic setting or the manual setting of the rotation speed.
2 Boost| When increasing boost timing, this will increase the motor speed and reduce the torque. If boost value has set too high, motor will become hot and may damage, so it is necessary to pay attention

to the motor temperature and make adjustments.

3 Boost Start RPM| Adjustment of boost start rotation speed.
4 Boost End RPM| Adjustment of boost end rotation speed.
5 Turbo Timing| The motor speed can be further increased when the transmitter is fully throttled. If turbo timing is raised too high, motor will become hot and may be damaged, so it is necessary to pay attention to

the motor temperature and make adjustments.

6 Turbo Start| Timing of entering turbo will be adjusted, and if set to 50%, the timing of entering turbo will be earlier.
7 Turbo Delay| The time is adjusted while switching from boost to turbo, and if set to 0.00 seconds, it will switch

from boost to turbo without a time lag, but heat generated by the motor will also increase.

8 Turbo Up Rake| Will be able to adjust the amount of turbo timing increase in 0.5 second increments. Increasing value may cause the motor to generate heat and cause damage. It is necessary to pay attention to motor

temperature and make adjustments.

9 Turbo Down Rake| Will be able to adjust the amount of turbo timing that drops when throttle is returned in 0.5 second increments. Increasing value will cause the turbo timing to drop faster and the response will increase,

but if turbo value is large, it may cause a phenomenon like braking.

[D.General Setting]
1 Running Mode| Three types of operation settings can be set: forward / brake, forward / reverse, forward / reverse / brake.
2 Battery| Select the battery type.
3 Cut oﬀ Voltage| Set the battery cut voltage.
4 Esc Over Heat Protect| Will be able to adjust the ESC operating cut temperature for ESC protection.
5 Motor Over Heat Protect| To protect the motor, you can set the temperature to cut operation of ESC when motor temperature

rises too high. This will not work if motor does not have a temperature sensor. ..

6 Neutral Range| Neutral width adjustment.
7 BEC Voltage| Will be able to adjust the voltage input to the receiver. When adjusted to 7V, a servo that supports

high voltage is required.

8 Motor Action| Will be able to set the direction of rotation of the motor.
9 Motor Link| Will be able to change the motor wire connection order to A.B.C or C.B.A. If needed to change this, check the ESC settings and connect the motor wire to his A.B.C terminal on the motor. There is a

risk of damage if connected incorrectly.

[E.Limit Vaiue]
1 Voltage Minimum| Minimum voltage during driving is displayed.
2 ESC temp Maximum| Maximum ESC temperature while driving is displayed.
3 Motor Tempreature maximum| Maximum temperature of motor while driving is displayed.
4 RPM Maximum| Maximum number of revolutions of motor while driving is displayed.
5 ClearLimit Record| Able to erase the data stored by ESC.
[F.Load Setting ]
1 Blinky Mode| Blinky mode and default setup.
2 Stock Mode| Stock mode and default setup.
3 Modify mode| Modify mode and default set. (Not included in RPX S)
4 Custom-1,2,3| Able to recall settings stored in Customs 1, 2, and 3. You can call it by pressing enter and then

pressing enter again.

[G. Save Setting]
