4. Setup & Installation
Follow these steps to correctly connect your GOUPRC 100A Brushless ESC to your RC vehicle components.
- Connect the Motor: Connect the three motor wires from the ESC to your brushless motor. Ensure correct phase connection (A-A, B-B, C-C). If the motor rotates in the wrong direction, swap any two of the three wires.
- Connect the Receiver: Plug the ESC's signal cable (usually a three-wire servo plug) into the throttle channel (CH2) of your RC receiver.
- Connect the Battery: Connect your 2S or 3S Lipo battery to the ESC's power input. Ensure the polarity is correct.
- Connect the Servo: If applicable, connect your steering servo to the steering channel (CH1) of your RC receiver.
- Power On: Turn on your remote controller first, then power on the ESC.

5. Operating Instructions
After successful installation, ensure your remote controller and ESC are properly calibrated for optimal performance. The ESC will typically auto-calibrate upon first power-up with the remote controller in neutral position. If the motor does not respond or behaves unexpectedly, refer to the troubleshooting section.
For advanced settings and fine-tuning, a programming card (sold separately or included in some kits) can be used. This allows adjustment of parameters such as cut-off voltage, drag brake, punch, and more.
6. Troubleshooting
If you encounter issues with your ESC, consider the following common problems and solutions:
Common Unsuccessful Throttle Alignment Problems:
- Throttle Channel Not Adjusted: If the throttle channel on your remote control is not adjusted to 100%, or the signal reception is not at the required value, the ESC may not operate normally, and the motor will not respond. Adjust the throttle channel to 100% and re-power the system.
- Throttle Trim Not Adjusted: If the throttle trim is not set to the '0' position, the signal may not be received correctly. The ESC and servo might operate, but the motor will not respond. Adjust the throttle trim to '0' and re-power the system.
- Throttle Channel Driving Direction Setting (for Remote Controls with Screens): Incorrect driving direction settings on advanced remote controls can prevent motor response. Verify and correct the throttle channel direction in your remote's settings.

7. Maintenance
Regular maintenance ensures the longevity and performance of your ESC:
- Cleaning: After each use, especially in dusty or wet conditions, clean the ESC with a soft brush or compressed air to remove dirt and debris. Ensure no moisture remains.
- Connection Check: Periodically inspect all wire connections (motor, battery, receiver) for any signs of wear, corrosion, or loose contacts. Secure any loose connections.
- Cooling Fan: Ensure the cooling fan (if present) is free from obstructions and operating correctly. A blocked fan can lead to overheating.
- Storage: Store the ESC in a dry, cool place away from direct sunlight and extreme temperatures.
