1. Introduction
This manual provides detailed instructions for the installation, operation, maintenance, and troubleshooting of your Hobbywing X9 Plus Power System. This system is specifically designed for 20L/25L multirotor agricultural drones, featuring a 9620 100KV motor and a 36-inch CCW propeller. Please read this manual thoroughly before using the product to ensure safe and optimal performance.
2. Setup and Installation
Proper installation is crucial for the performance and safety of your drone. Follow these steps carefully:
- Unboxing and Inspection: Carefully unpack all components. Verify that all parts are present and undamaged. Refer to Figure 1 for a visual guide of the components.
- Motor Mounting: Secure the X9 Plus motor unit to your drone's frame using appropriate screws and the provided mounting plate. Ensure the motor is firmly attached and aligned correctly.
- Wiring Connection: Connect the motor's power cables to the Electronic Speed Controller (ESC) according to the wiring diagram. Pay close attention to polarity (red to positive, black to negative) and ensure secure connections. The X9 Plus motor unit includes integrated wiring for convenience.
- Propeller Installation: Attach the 36-inch CCW propeller to the motor shaft. Ensure the propeller is oriented correctly for counter-clockwise rotation and tightened securely. Refer to the video demonstration for visual guidance.
- Battery Connection: Connect the recommended 12-14S LiPo battery to the ESC. Double-check all connections before powering on.

3. Operating Instructions
The Hobbywing X9 Plus Power System is designed for high-performance agricultural drone applications. Ensure your drone's flight controller is properly configured for the motor and ESC combination.
- Pre-Flight Check: Before each flight, inspect all components for any loose connections, damage, or debris. Ensure propellers are securely fastened and free from cracks.
- Power On Sequence: Connect the flight battery. The ESC will perform a self-test and emit a series of beeps. Wait for the initialization sequence to complete before arming the motors.
- Throttle Control: The ESC supports a throttle signal frequency of 50-500Hz and an operating pulse width of 1050-1950us. Ensure your flight controller's PWM output matches these specifications.
- Motor Direction: The motor steering is Counter-Clockwise (CCW). Verify correct motor rotation before flight. If the direction is incorrect, adjust the motor phase wires or ESC settings as per your flight controller/ESC manual.
- Environmental Conditions: Operate the power system within the recommended operating temperature range of -20℃ to 50℃. The system has an IPX7 waterproof rating, offering protection against water immersion up to 1 meter for 30 minutes, but prolonged exposure to harsh conditions should be avoided.
4. Maintenance
Regular maintenance ensures the longevity and reliability of your power system.
- Cleaning: After each use, especially in agricultural environments, clean the motor and propeller to remove any dirt, dust, or chemical residues. Use a soft, dry cloth. Avoid using harsh chemicals that could damage components.
- Inspection: Periodically check the motor bearings for smooth operation. Inspect propellers for any signs of wear, cracks, or imbalance. Replace damaged propellers immediately.
- Wiring: Ensure all wiring connections remain secure and free from corrosion or fraying.
- Storage: Store the power system in a cool, dry place away from direct sunlight and extreme temperatures when not in use.
5. Troubleshooting
Here are some common issues and their potential solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Motor not spinning | Loose wiring, incorrect battery connection, ESC not armed, damaged motor/ESC. | Check all wiring, ensure battery is connected correctly, arm ESC via flight controller, inspect motor/ESC for damage. |
| Incorrect motor rotation | Incorrect motor phase wiring. | Swap any two of the three motor phase wires connected to the ESC, or adjust settings in the ESC/flight controller. |
| Reduced thrust/performance | Damaged propeller, low battery voltage, motor overheating. | Replace propeller, ensure battery is fully charged and healthy, check for obstructions to motor cooling. |
| Unusual noise/vibration | Damaged propeller, loose motor mount, worn bearings. | Inspect/replace propeller, tighten motor mounting screws, check motor bearings for wear. |
If you encounter issues not listed here or if the suggested solutions do not resolve the problem, please contact customer support.
