1) Compatibility Compatible with most models of mini drones. The propeller size, curvature and interface specifications have been precisely calculated to ensure compatibility with the drones power system. After installation, it operates smoothly without affecting flight control sensitivity or stability. 2) Durable material Made of durable engineering plastic, its toughness and impact resistance are enhanced through special processes. It can withstand collisions and scratches during daily flights, is less likely to break or deform, extends its service life, and reduces the cost of frequent replacement. 3) Stability The unique blade cross section and helical angle design can efficiently cut through the air during rotation, providing strong lift and stable thrust, helping the unmanned aerial vehicle achieve rapid takeoff, flexible turning and smooth hovering, optimizing flight performance. 4) Easy installation No complex tools are required. The propeller can be easily disassembled and installed through simple plugging, unplugging or screwing operations. Clear forward and reverse paddle markings are provided to prevent installation errors. Use scenarios Outdoor practice and mini drone racing: Quick takeoff and stable control during fast maneuvers, helping pilots train precision and responsiveness. Aerial photography and videography: Steady hover and reliable lift support smooth framing and motion capture in open spaces. Indoor flight and obstacle course training: Durable design reduces downtime after collisions, enabling more consistent practice sessions.
