Accurate positioning to prevent the phenomenon of backward sweep during propeller operation, and 

the propeller is fixed in the accurate position when retracted, making it convenient for storage and transportation.

Compatible with thrust and tension installation

The special version of the "thrust propeller" is only suitable for installation on motors 

with coaxial frames facing downwards.

Before using this product, please check if all of the above items are included in the product packaging. If there are any missing items, please contact customer service promptly.

Precautions

(1) When the propeller model is marked with "L" after use, the propeller and motor rotate clockwise (when viewed from above); When the propeller model is marked with "R" after use, the propeller and motor rotate counterclockwise (when viewed from above).     

(2) The propeller material is sturdy and strong. If it comes into contact with unprotected body parts during high-speed rotation, it can cause great harm. Please use it with caution.     

(3) The strength of the propeller structure has been thoroughly tested. Please use it reasonably within the recommended maximum pulling force range. Exceeding the limit pulling force will damage the blade; Please do not test the strength of the blade by bending it with bare hands, as this method may result in significant differences in force compared to actual flight and may also cause damage to the blade.     

(4) Please carefully check whether the screws on the cover plate are installed properly before use, and the propeller must be installed properly     

(5) Before takeoff, it is necessary to check whether the installation screws are tightened, whether the propeller is damaged, and whether there is a risk of fracture for cracked blades. Please replace them in a timely manner.     

(6) When storing propellers, corrosive gases and environments with books should be avoided, as well as temperature ranges not exceeding 0-40 ℃ and humidity ranges of over 80%. Especially when stored for a long time, more attention should be paid.     

(7) The propeller must be installed on the motor, and the installation screws must be coated with anaerobic screw glue of medium strength or above. 

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