1. Introduction
Thank you for choosing the APISQUEEN Feather 8S 32V 80A Electric Speed Controller (ESC). This high-performance, waterproof ESC is designed for use with brushless motors in applications such as underwater propulsion systems and RC boats. Its robust metal casing ensures durability and reliable operation in demanding environments. This manual provides essential information for the safe and efficient setup, operation, and maintenance of your ESC.
2. Safety Instructions
- Always disconnect the battery from the ESC when not in use to prevent accidental motor startup.
- Ensure all connections are secure and properly insulated to avoid short circuits.
- Operate the ESC within its specified voltage and current limits (2-8S LiPo, 80A continuous, 90A burst). Exceeding these limits can damage the ESC and connected components.
- Keep the ESC away from flammable materials during operation, as it may generate heat.
- This product is not a toy. Keep out of reach of children. Recommended age for use is 14+ years.
- If the ESC becomes excessively hot, immediately disconnect power and allow it to cool before further use.

5. Setup Guide
5.1 Wiring Connections
Refer to the connection diagram below for proper wiring. Ensure all connections are firm and correctly polarized.
- Battery Connection: Connect the positive (+) terminal of your LiPo battery to the red wire of the ESC and the negative (-) terminal to the black wire of the ESC. Ensure correct polarity to prevent damage.
- Motor Connection: Connect the three wires (A, B, C) from the ESC to the three wires of your brushless motor. The order of these connections may affect motor rotation direction. If the motor spins in the wrong direction, swap any two of the three wires.
- Receiver Connection: Connect the PWM input signal cable from the ESC to the throttle channel of your RC receiver. This cable transmits control signals from your remote control to the ESC.
5.2 Initial Calibration (if applicable)
While this ESC does not specify a BEC output, standard ESC calibration procedures generally involve:
- Turn on your transmitter and set the throttle stick to its maximum position.
- Connect the battery to the ESC.
- Listen for a series of beeps from the motor, indicating the ESC has detected the maximum throttle signal.
- Move the throttle stick to the minimum position.
- Listen for another series of beeps, indicating the ESC has detected the minimum throttle signal and is now calibrated.
- Disconnect the battery. The ESC is now ready for use.
Note: Specific calibration steps may vary depending on your motor and receiver. Consult their respective manuals if issues arise.
6. Operating Instructions
- Ensure all connections are secure and the ESC is properly mounted in your vehicle.
- Turn on your RC transmitter.
- Connect the battery to the ESC. The ESC will initialize, and the motor may emit a series of beeps.
- Slowly increase the throttle on your transmitter to start the motor.
- Observe the motor's behavior and ensure smooth operation.
- To stop the motor, return the throttle stick to the minimum position.
- After use, always disconnect the battery from the ESC first, then turn off your transmitter.
7. Maintenance
- Cleaning: Although waterproof, it is recommended to rinse the ESC with fresh water after use in saltwater or dirty conditions. Ensure it is completely dry before storage or next use.
- Inspection: Regularly inspect all wires and connectors for signs of wear, corrosion, or damage. Replace any damaged components immediately.
- Storage: Store the ESC in a cool, dry place away from direct sunlight and extreme temperatures.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Motor does not start or stutters. | Incorrect wiring, uncalibrated throttle, low battery, motor/ESC damage. | Check all connections. Recalibrate throttle. Charge/replace battery. Inspect motor and ESC for damage. |
| Motor spins in the wrong direction. | Incorrect motor wire connection order. | Swap any two of the three motor wires connected to the ESC. |
| ESC gets excessively hot. | Overload, insufficient cooling, short circuit. | Reduce load. Ensure adequate airflow/water cooling. Check for short circuits. |
| No response from ESC. | No power, faulty signal cable, damaged ESC. | Check battery connection. Verify signal cable is connected to the correct receiver channel. Test with another ESC if possible. |
9. User Tips
- For optimal performance, ensure your battery's C-rating is sufficient for the 80A continuous current draw.
- Consider using waterproof connectors for all battery and motor connections, especially in marine environments, to enhance reliability.
- Always perform a range check with your RC system before operating your vehicle to ensure proper signal reception.
