3. Propeller Identification and Specifications
The propellers are categorized into 'A' and 'B' types, which are crucial for correct installation to ensure proper drone flight. The shaft diameter for these propellers is 0.8 mm. The propeller lengths vary, including 37mm, 42mm, and 46mm options, with a 1mm hole diameter (0.04 inches) for mounting.
Propeller Details:
- Shaft Diameter: 0.8 mm
- Hole Diameter: 1 mm (0.04 inches)
- Lengths: 37 mm, 42 mm, 46 mm (1.8 inches)
- Types: A and B (clockwise and counter-clockwise rotation)

4. Installation
Follow these steps to correctly install or replace the propellers on your Q9S or Q9C drone:
- Identify Propeller Type: Each propeller is marked with either 'A' or 'B'. Ensure you match the correct propeller type to the corresponding motor on your drone. Incorrect placement can lead to unstable flight or prevent the drone from taking off.
- Remove Old Propeller (if applicable): Carefully unscrew and remove any damaged propellers. Keep track of the screws.
- Align New Propeller: Place the new propeller onto the motor shaft, ensuring the hole aligns with the shaft.
- Secure with Screws: Use the provided screws to firmly attach the propeller to the motor. Do not overtighten, as this can damage the propeller or motor.
- Verify Rotation: After installation, manually spin each propeller to ensure it rotates freely without obstruction. The 'A' propellers typically rotate clockwise, and 'B' propellers counter-clockwise, but always refer to your drone's specific manual for exact orientation.
Important: Always check the orientation of the blades (clockwise and counter-clockwise) before replacing them. Refer to your drone's original manual for specific motor assignments.
5. Operating the Drone (General Information)
While this manual focuses on propellers, understanding general drone operation is key to their longevity. The AVIALOGIC Q9S/Q9C drone is designed for ease of use, featuring one-press takeoff and landing, altitude hold, and multiple speed settings. It also includes headless mode for simplified control and propeller guards for protection.

6. Maintenance
Regular maintenance of your propellers is essential for safe and efficient drone operation:
- Inspect Regularly: Before and after each flight, visually inspect all propellers for any signs of damage, cracks, bends, or debris.
- Clean Propellers: If dirt or debris accumulates on the propellers, gently clean them with a soft, dry cloth. Avoid using harsh chemicals.
- Replace Damaged Propellers: Even minor damage can affect flight stability and safety. Replace any damaged propeller immediately with a new one of the correct type (A or B).
- Store Properly: When not in use, store spare propellers in a cool, dry place away from direct sunlight and extreme temperatures to prevent warping or degradation.
7. Troubleshooting
If you encounter issues after replacing propellers, consider the following:
- Drone Unstable/Drifting: Double-check that 'A' and 'B' propellers are installed on their correct motor positions. Refer to your drone's manual for the specific layout.
- Unusual Noise/Vibration: This often indicates a bent or damaged propeller. Inspect all propellers closely and replace any that appear compromised. Ensure screws are tightened appropriately.
- Drone Not Taking Off: Verify that all propellers are spinning in the correct direction. If not, recheck installation and propeller types. Ensure the drone's battery is fully charged.
