5. Guide d'installation
Replacing motor gears requires careful handling. Always refer to your specific drone's service manual for detailed disassembly and reassembly instructions, as procedures may vary significantly between models.
- Préparation: Ensure the drone is powered off and the battery is disconnected. Gather necessary small tools such as small pliers and screwdrivers.
- Access Motors: Carefully remove the drone's casing or propeller guards to access the motor shafts. This step is highly dependent on your specific drone model.
- Retirer les vieux équipements : Gently cut or pry off the worn or damaged gear from the motor shaft. Exercise caution to avoid damaging the motor or the shaft itself.
- Sélectionnez le bon rapport de vitesse : Identify the correct gear size (1mm or 1.2mm axis hole) that fits snugly onto your motor shaft. The gear must fit tightly to prevent slippage during operation.
- Installer du nouveau matériel : Align the new gear with the motor shaft. Using small pliers or a similar tool, carefully press the new gear onto the shaft until it is fully seated. Ensure the gear is straight and does not bind.
- Test d'ajustement : Manually rotate the motor shaft to ensure the newly installed gear spins freely without any obstruction.
- Remonter: Reattach any removed casing or propeller guards. Reconnect the battery.
- Test de fonctionnement : Perform a low-power test flight or motor spin test to confirm proper operation before attempting a full flight.

6. Entretien
To ensure optimal performance and longevity of your motor gears, follow these maintenance guidelines:
- Regularly inspect the gears for any signs of wear, cracks, or missing teeth.
- Clean any debris such as dust, hair, or small particles that may accumulate around the gears and motor shafts.
- Avoid hard landings or crashes, as these can significantly damage the gears and other drone components.
- Store spare gears in a clean, dry place away from direct sunlight and extreme temperatures.
7. Dépannage
If you encounter issues after installing the new motor gears, consider the following:
- Gear slips on shaft: Ensure that the correct gear size (1mm or 1.2mm hole) was selected for your motor shaft. If the fit is still loose, a small amount of hobby-grade adhesive designed for plastics can be applied to the shaft before pressing the gear on. Allow sufficient drying time before operation.
- Drone not flying straight or motor issues: Check all motor gears for any signs of damage or improper installation. Also, ensure that propellers are correctly attached and undamaged.
- Gears making unusual noise: Inspect the gears and motor area for foreign objects, misalignment, or excessive wear. Replace any damaged gears promptly.
