Enhance the performance of your 90mm RC plane with this high-quality RC Ducted Fan, meticulously crafted from durable aluminum alloy, plastic, and copper materials. Designed for precision and efficiency, this ducted fan features a vortex blade type with 12 carbon fiber mixed blades that deliver exceptional strength, toughness, and minimal deformation, ensuring smooth and pure sound operation even at high speeds. The main barrel’s robust aluminum alloy construction provides high strength and resists deformation, protecting the inner wall from blade scratches and maintaining optimal duct efficiency with only a 0.5mm gap between the blades and the barrel wall. Key Features: · Premium Aluminum Alloy Main Barrel: High strength and deformation resistance protect the duct and improve durability during intensive RC plane flights. · Carbon Fiber Mixed Blades: Each of the 12 vortex blades is engineered for superior toughness and strength, reducing the risk of breakage and ensuring stable, resonance-free rotation. · High-Efficiency Duct Design: The minimal 0.5mm seam between blades and barrel wall maximizes airflow efficiency, enhancing thrust and overall performance. · Motor Mount with Heat Dissipation: The motor mounting seat is designed to dissipate heat effectively and prevent installation offset, reducing axle deviation and avoiding potential damage or flight accidents. · Precision Balanced Blades: Individually balanced blades with minimal weight variance enable high-efficiency motor operation without resonance, facilitating quick and accurate dynamic balancing tests. · Easy Assembly and Maintenance: Separate blades allow for flexible assembly and symmetrical alignment, improving test passing efficiency and simplifying blade pairing.
