Advantages and Application

The propellers are made of impact-resistant polycarbonate, ensuring high strength at low weight. The four-blade design enhances thrust and stability, making flight more controlled during rapid maneuvers and acrobatics. The blue and black design adds aesthetics to your drone, distinguishing it from other models. Recommended for whoop drone pilots who aim to improve the balance between thrust and energy efficiency.

Installation and Operation Recommendations

Before installation, ensure correct propeller orientation: follow the CW/CCW markings. Use a 1.5 mm diameter shaft, which matches the hole in the center of the propeller. Balance each propeller to reduce vibrations and extend the lifespan of motors and bearings. During operation, avoid strong impacts with hard surfaces; polycarbonate increases durability, but contact can damage the blades.

Who this kit is suitable for

This kit is suitable for owners and pilots of whoop drones with 1103–1105 motors who are looking for improved handling, stability, and component durability. It is an optimal choice for stunt flights indoors and outdoors in confined spaces where precision and control are crucial.
