Propeller cover Sunnylife A3S-KC910 for AIR 3S / AIR 3 — replacement protective guards

The Sunnylife A3S-KC910 propeller guard for AIR 3S and AIR 3 is a lightweight replacement protective cover designed to isolate and protect rotating propellers during low-altitude flights, transport and storage. Made of durable plastic and developed with mechanical principles in mind, the guard reduces the risk of propeller damage and limits accidental contact with surroundings while preserving flight performance due to its low net weight of 84 g.

Advantages

The guard features a multi-arc arm design with shock-absorbing properties that reduces vibrations and improves flight stability. Its integrated anti-shock structure and half-open fortress geometry increase impact resistance and prevent deformation. The product is easy to install and remove, compact for storage, and provides a safety barrier that protects people and objects near the drone.

Suitable for

• Owners of AIR 3S and AIR 3 drones who need propeller protection
• Flying in confined spaces or near obstacles
• Low-altitude flights where accidental contact is possible
• Transport and storage to reduce risk of propeller damage

How to use

Attach the Sunnylife A3S-KC910 guard to the drone’s motor arms according to the alignment points or slots on the cover until it clicks or fits securely.

Remove the guard before stowing the drone for flight that requires unimpeded propeller airflow or when performing maintenance. Follow the drone manufacturer’s instructions regarding accessories and pre-flight checks.

Usage recommendations

Use the propeller guard for indoor flights, low-altitude operation and when transporting or storing the drone. Regularly inspect the cover for cracks or deformation and replace it if damaged. Do not rely solely on the guard to prevent all collisions; maintain safe distances from people and obstacles and follow standard flight safety procedures.
