4. Safety Information
- Always disconnect the battery from the ESC when not in use to prevent accidental motor activation.
- Ensure correct polarity when connecting the battery. Incorrect connection can cause severe damage to the ESC and battery.
- Avoid short circuits. Inspect all wires and connectors for damage before each use.
- Operate in a well-ventilated area. ESCs can generate heat during operation.
- Keep away from water and moisture. This ESC is not waterproof.
- Do not exceed the specified current and voltage ratings (30A continuous, 40A peak, 2-3S LiPo). Overloading can lead to overheating and failure.
- Keep hands and loose clothing away from rotating propellers and motors when the battery is connected.
5. Setup and Installation
Proper installation is crucial for the performance and longevity of your ESC. Follow these steps carefully:
- Motor Connection: Connect the three blue wires from the ESC to the three motor wires. For brushless motors, the order of these wires can affect motor rotation direction. If the motor spins in the wrong direction, swap any two of the three wires.

- Receiver Connection: Connect the small three-wire servo connector (usually brown, red, orange/yellow) from the ESC to the throttle channel of your RC receiver. This is typically channel 3 for airplanes and drones. Ensure the signal wire (orange/yellow) is connected to the signal pin, the positive wire (red) to the positive pin, and the negative wire (brown) to the negative pin.

- Battery Connection: Connect your 2-3S LiPo battery to the XT60 plug on the ESC. Ensure the battery is fully charged and has the correct voltage for your setup.
- Mounting: Securely mount the ESC within your RC vehicle, ensuring adequate airflow for cooling. Avoid mounting it in enclosed spaces without ventilation. The independent heat sinks are designed to dissipate heat effectively.

6. Operating Instructions
After successful installation, follow these steps to operate your ESC:
- Transmitter Setup: Ensure your RC transmitter's throttle stick is at its lowest position (zero throttle).
- Power On: Connect the LiPo battery to the ESC's XT60 plug. The ESC will emit a series of beeps indicating cell count and readiness.
- Arming: Once the ESC has initialized, it will typically emit a final beep to indicate it is armed and ready for operation.
- Throttle Control: Slowly advance the throttle stick on your transmitter. The motor should begin to spin. Increase throttle gradually for smooth acceleration.
- Motor Direction: If the motor spins in the opposite direction to what is desired, disconnect the battery, then swap any two of the three motor wires connected to the ESC. Reconnect the battery and test again.
- Power Off: Always reduce the throttle to zero, then disconnect the battery from the ESC first before turning off your transmitter.
7. Maintenance
Regular maintenance helps ensure the longevity and reliability of your ESC:
- Inspection: Periodically inspect the ESC for any signs of physical damage, frayed wires, or loose connections.
- Cleaning: Keep the ESC free from dust, dirt, and debris. Use a soft brush or compressed air to clean the heat sinks and components.
- Temperature Monitoring: During operation, monitor the ESC temperature. If it consistently runs excessively hot, consider improving ventilation or reducing load.
- Storage: Store the ESC in a dry, cool environment away from direct sunlight and extreme temperatures.
8. Troubleshooting
If you encounter issues with your ESC, refer to the following troubleshooting guide:
| Problem | Possible Cause | Solution |
|---|---|---|
| Motor does not spin or stutters. | Incorrect motor wiring; ESC not armed; low battery voltage; motor or ESC damage. | Check motor wire connections (swap two if needed); ensure throttle is at zero during power-up; check battery charge; inspect motor and ESC for damage. |
| ESC beeps continuously or irregularly. | Low battery voltage; no signal from receiver; ESC error. | Charge battery; check receiver connection and transmitter power; consult ESC beep codes if available (not provided in this manual). |
| ESC or motor overheats. | Overloading (too large propeller/motor for ESC); insufficient cooling; short circuit. | Reduce load; improve ventilation; check for short circuits; ensure continuous current is within 30A. |
| No power to receiver/servos. | BEC failure; incorrect receiver connection. | Check receiver wiring; test with another BEC or receiver if possible. |
