5. Configuração e instalação
Proper installation of the ESC is crucial for safe and optimal performance. Follow these steps for connecting your ZTW Beatles G2 40A ESC:
- Conecte os fios do motor: Connect the three black motor wires from the ESC to your brushless motor's connectors. The order of connection determines the motor's rotation direction. This can be adjusted later during commissioning.
- Connect Receiver Signal Wire: Connect the ESC's black-red-white 3-pin signal wire to your receiver's throttle channel.
- Secure ESC: Secure the ESC and its XT60 power connector to the arm of your RC model using zip ties or other appropriate fasteners. Ensure they are firmly secured to prevent movement during operation.
- Fonte de energia: Connect the XT60 plug from the ESC to your battery.

6. Operação
6.1. Throttle Calibration
Throttle calibration is essential for the ESC to correctly recognize the throttle range of your transmitter. This procedure should be performed before the first use or if you change your transmitter.
- Turn on your transmitter and move the throttle stick to the highest position.
- Connect the ESC's power wires to the battery.
- Listen for two beeps from the ESC.
- Immediately move the transmitter's throttle stick to the lowest position.
- Listen for a confirmation tone from the ESC. This indicates successful calibration.
- Disconnect the battery and then reconnect it. If the throttle responds normally, calibration is complete.

6.2. Programming the ESC
The ZTW Beatles G2 40A ESC offers several programmable functions such as brake type, cut-off voltage, soft start, and motor direction. Programming can be done using your transmitter or an optional LCD Program Card G2.
Programming via Transmitter:
- Ligue o transmissor e mova o stick do acelerador para a posição superior.
- Conecte uma bateria ao ESC.
- Listen for a series of beeps indicating entry into programming mode. Each beep sequence corresponds to a specific parameter.
- Move the throttle stick to the bottom position to enter the corresponding parameter item.
- Move the throttle stick to the top position to save the selected parameter value. Programming is completed.
- Disconnect the battery to exit programming mode.
Video: This video demonstrates how to program your ESC using the transmitter.
Programming via LCD Program Card G2:
- Unplug the ESC throttle cable from the receiver.
- Insert the LCD Program Card G2 into the ESC's throttle cable.
- Conecte o ESC à bateria.
- Wait for the LCD screen to display the power-on interface.
- Press the "ITEM" or "OK" button to select parameters and program.
- Upon completion of programming, press the "OK" button to save the parameters.
Video: This video shows how to set parameters for the Mantis Slim G2 ESC using an LCD Program Card.
6.3. SMR (Switch Motor Rotation) Function
The SMR function allows you to change the motor rotation direction. This is particularly useful for aircraft landing, as it can effectively shorten the landing distance.
- Ensure the SMR function is set to "ON" in the ESC programming.
- With the throttle below 50%, flip the 2-stage switch on your transmitter to change the motor rotation.
Note: The SMR function is only effective when the throttle is below 50% and is primarily intended for use during aircraft landing to shorten the landing distance.

8. Solução De Problemas
If you encounter issues with your ZTW Beatles G2 40A ESC, consider the following common troubleshooting steps:
- Motor não gira:
- Check all power connections (battery to ESC, ESC to motor).
- Ensure the throttle is calibrated correctly.
- Verify that the receiver is properly bound to the transmitter.
- Inspect motor wires for loose connections or damage.
- Motor stutters or runs irregularly:

- Superaquecimento do ESC:
- Ensure adequate ventilation around the ESC.
- Check for excessive current draw (e.g., oversized propeller, motor issues).
- Verify motor timing is not set too aggressively.
- No response from ESC after power-on:
- Verifique a conexão e o volume da bateriatage.
- Ensure the ESC's signal wire is correctly plugged into the receiver.
- Re-perform throttle calibration.
