1. Overview
The HOBBYWING Fusion 8ight 2in1 FOC System integrates the Electronic Speed Controller (ESC) and motor into a single unit, simplifying the layout and wiring of your remote-controlled vehicle. This system utilizes Field Oriented Control (FOC) driving mode, which significantly enhances the power delivery for rock crawlers by providing strong low-speed torque and improved control. Its high efficiency minimizes heat generation, extending runtime and ensuring quieter, smoother motor operation. The system is designed with IP67 protection, ensuring reliable performance across various conditions.
Key features include intelligent torque output, closed-loop speed control for precise handling, and active drag brake force adjustment for superior holding power on inclines. A robust built-in switch mode BEC delivers adjustable voltages (6V/7.4V/8.4V) and continuous/peak current of up to 6A/13A, suitable for high-torque and high-voltage servos. Real-time drag brake force adjustment is also possible via your transmitter's AUX channel. The system incorporates multiple protection functions, including low battery voltage, overheat, throttle loss, and lock-up protections. It is compatible with LED and LCD Program Box Pro/G2 for convenient parameter adjustments.

2. Safety Information
To ensure safe operation and prevent damage, please adhere to the following safety guidelines:
- Carefully check power devices and the manual of your car frame to ensure proper power pairing. Incorrect pairing can lead to overload and motor damage.
- Always wire all equipment parts carefully. Loose connections due to vibration may cause loss of control of your RC model.
- Never apply full throttle without the pinion installed. Extremely high RPMs without load can damage the motor.
- Avoid motor case temperatures exceeding 100 degrees Celsius (212 degrees Fahrenheit) to prevent demagnetization of the magnets.

5. Setup & Installation
Follow these steps to install and set up your HOBBYWING Fusion 8ight 2in1 FOC System:
- Mounting the System: Securely mount the integrated motor/ESC unit in your vehicle chassis. Ensure proper ventilation around the unit.
- Wiring Connections: Connect the power wires to your battery. Connect the signal wire from the ESC to the throttle channel of your receiver. If using real-time drag brake adjustment, connect the yellow signal wire to an available AUX channel on your receiver.
- On/Off Switch: Mount the on/off switch in an accessible location using the provided mounting tape.
- Automatic Motor Pairing (Sensor Reset): This process calibrates the motor's sensors with the ESC.
- Ensure the motor is free to rotate (no pinion installed).
- Connect the battery to the ESC.
- Press and hold the on/off button until the LED flashes green (approximately 3-5 seconds).
- Release the button. The motor will emit a series of beeps, indicating successful pairing.

6.2. Using the HW Link App (Bluetooth)
The Fusion 8ight 2in1 FOC System features built-in Bluetooth connectivity. Download the HW Link App on your smartphone. Connect to the device via Bluetooth to access parameters, firmware updates, and data logs.
6.3. Key Parameter Settings
The system offers 13 adjustable settings to accommodate diverse application requirements:
- Running Mode: Select between Fixed Speed Mode, Forward/Reverse with Brake (Normal Mode), or Forward/Reverse (Normal Mode without fixed speed).
- Lipo Cells: Auto-detect or manually set the number of LiPo cells.
- Cutoff Voltage: Configures the low voltage cutoff protection (Disabled, Low, Medium, High).
- ESC Thermal Protection: Sets the ESC overheat protection threshold (Disabled, Low, High).

7. Maintenance
Regular maintenance ensures the longevity and optimal performance of your Fusion 8ight system:
- Keep the motor/ESC unit clean and free from dirt, dust, and moisture.
- Regularly inspect all wiring and connectors for signs of wear or damage.
- Ensure the motor bearings are smooth and free from obstruction.
- Check for any loose screws on the motor or mounting points.
- Store the unit in a dry, cool environment when not in use.
8. Troubleshooting
If you encounter any issues with your Fusion 8ight system, consider the following:
- Motor Overheating/Abnormal Operation: If the motor or ESC overheats or behaves unusually, perform the Automatic Motor Pairing (Sensor Reset) procedure as described in the Setup section. This often resolves sensor-related issues.
- Loss of Control/Intermittent Operation: Check all wiring connections, receiver, and transmitter for proper function. Ensure battery voltage is sufficient.
- Incorrect Motor Rotation: If the motor rotates in the wrong direction, adjust the 'Motor Rotation' parameter in the ESC settings (do not adjust via transmitter).
- Lack of Power/Response: Verify battery charge, check all connections, and ensure appropriate gearing for your vehicle. Adjust 'Punch' settings for desired throttle response.
