50mm Ducted Fan, Powerful 12-Blade Electric Ducted Fan for RC Airplane Enthusiasts (5000kv Clockwise)

[High-rigidity injection-molded material for low loss and long life] The duct fan body is made entirely from injection-molded compound (aluminum alloy + plastic + copper composite structure), which provides high rigidity and hardness, significantly reducing the loss rate caused by impacts when launching and landing an RC airplane or contact with small obstacles in the air, and achieving durability that can withstand long-term flight needs. [12-Blade + Dynamic Balance Design for Excellent Aerodynamics] The 12-blade configuration undergoes rigorous dynamic balance testing before shipping, minimizing blade vibration during rotation and optimizing coordination with the fan duct. The excellent balance of airflow and thrust, along with the proven high aerodynamic efficiency, provides stable lift and thrust for your RC airplane. [High Power and Efficiency with Brushless Motor] The built-in brushless motor (9N6P, approximately 25.8mm diameter) delivers high power with a continuous output of 550W and a continuous current of 45A. It generates less heat and is more energy efficient than a brushed motor. Powered by a 3-4S LiPo battery, it enables high-speed cruising, rapid acceleration, and extended flight times for your RC airplane. [50mm Size for Versatility and Easy Installation] Designed with a standard 50mm (2.0 inch) size, it easily fits most small and medium-sized RC airplanes on the market (e.g., jet and fixed-wing models). It can be easily replaced with your existing RC airplane's power system without requiring specialized modifications, making it ideal for power upgrades or replacing a broken old fan. [Safety precautions included] Safe use is emphasized, with detailed safety precautions included, such as prohibiting use by minors, not looking directly at the intake and exhaust ports while in operation, and not testing the power on by hand. It also provides tips on how to avoid contact with rotating parts and the introduction of foreign objects, helping users to use the product correctly and safely (due to manual measurements, there may be a 1-3mm discrepancy in dimensions).
