Environmental Conditions

• Operating Temperature: -40°C ~ 65°C
• Storage Temperature: -10°C ~ 50°C
• Storage Humidity: <85% RH (No condensation)

Precautions

1. Propellers marked “L” rotate counterclockwise when used with a motor (viewed from the front); propellers marked “R” rotate clockwise when used with a motor (viewed from the front).

2. Propellers are rigid structures. During high-speed rotation, contact with fragile or unprotected parts of the human body may cause severe injury. Use with extreme caution.

3. The propeller structure has been sufficiently strength-tested. Please operate reasonably within the recommended maximum thrust range. Exceeding the maximum thrust limit may cause blade damage. Do not attempt to test blade strength by bending or similar methods, as the force conditions differ greatly from actual flight and may also cause damage.

4. Before use, carefully check whether the propeller mounting screws are properly installed. The propeller must be securely mounted in place.

5. Before each flight, check whether the mounting screws are tightened. If the propeller is damaged or cracked, there is a risk of blade fracture—replace it immediately.

6. When storing propellers, avoid corrosive gases, harmful environments, temperatures exceeding -40°C ~ 0°C, and humidity above 80%. Pay special attention during long-term storage.

7. When installing the propeller on the motor, be sure to apply medium or higher strength threadlocker to the mounting screws.

8. Please comply with local laws and regulations when using this product.
