Setup and Installation
1. Propeller Installation
- Ensure the drone is powered off and the battery is removed before beginning installation.
- Identify the correct propellers for each motor. Propellers are typically marked (e.g., A or B) and must match the markings on the drone's motor arms.
- Align the propeller with the motor shaft. Use the provided screwdriver and screws to securely fasten each propeller. Do not overtighten.
- Gently test each propeller to ensure it is firmly attached and spins freely without obstruction.
2. Propeller Guard Installation
- Locate the mounting points for the propeller guards on the drone's motor arms.
- Snap or slide each propeller guard into its designated position. Some guards may require a slight force to click into place.
- Ensure all four guards are securely attached and do not interfere with propeller rotation.

Maintenance
- Propellers: Regularly inspect propellers for cracks, bends, or chips. Damaged propellers can affect flight stability and efficiency. Replace them immediately if any damage is observed.
- Propeller Guards: Check guards for damage after any impact. Ensure they remain securely attached to the drone.
- Screws: Periodically check all screws for tightness. Loose screws can lead to component detachment during flight.
- Cleaning: Use a soft, dry cloth to clean propellers and guards. Avoid using harsh chemicals.
Troubleshooting
- Drone unstable after propeller replacement: Ensure propellers are installed correctly (A to A, B to B) and are securely tightened. Check for any bent or unbalanced propellers.
- Propeller guards falling off: Verify that the guards are fully snapped into place. If they are consistently loose, they may be damaged and require replacement.
- Charging cable not working: Ensure the cable is properly connected to both the power source and the drone battery (if applicable). Test with another compatible charging port or cable if possible.
