7. Instruccions de funcionament
Once installed, the propeller guards provide an added layer of protection. While they enhance safety, they may slightly alter the drone's flight characteristics due to added weight and air resistance. It is recommended to perform a test flight in a safe, open area after installation to familiarize yourself with any changes in handling.
- Always fly responsibly and adhere to local drone regulations.
- Propeller guards are most beneficial in confined spaces or when flying near obstacles.
- Be aware that guards can sometimes get caught on objects, potentially leading to a crash.
8. Manteniment
- Neteja: Wipe the guards with a soft, damp cloth to remove dust or debris. Avoid harsh chemicals that could damage the PP material.
- Inspecció: Regularly inspect the guards for cracks, bends, or any signs of damage. Even minor damage can compromise their protective capabilities and potentially affect flight stability.
- Substitució: If a guard is significantly damaged, replace it immediately to ensure optimal protection and flight performance.
9. Solució De Problemes
- Vibration during flight:
- Ensure all propeller guard mounting screws are tight.
- Check if any guard is bent or warped, causing it to rub against the propeller.
- Verify that propellers are balanced and undamaged.
- Guards feel loose:
- Re-tighten all mounting screws. Do not overtighten, as this can strip threads or crack the plastic.
- Ensure the correct screw length is used for your motor and frame combination.
10. Consells d'usuari
- Consider using propeller guards when flying indoors or in tight outdoor environments to minimize damage to your drone and surroundings.
- For optimal performance, ensure the propeller guards are compatible with your specific motor and propeller size.
- While guards offer protection, they are not indestructible. Avoid severe impacts to prolong their lifespan.
