High-Thrust & Stable Performance｜120mm Full-Metal 12-Blade EDF Ducted Fan for Large RC Jet Models

As the core propulsion unit of large-scale jet models, Electric Ducted Fan (EDF) systems directly determine the aircraft’s thrust output, flight stability and simulation effect. To meet the high-standard power demands of professional RC jet enthusiasts, we have launched the upgraded 120mm full-metal 12-blade EDF ducted fan power system, offering high efficiency, strong durability and universal compatibility for premium large-size model aircraft.

This 120mm EDF adopts a precision 12-blade aerodynamic curved impeller design. Compared with conventional ducted fans, it optimizes air guidance, reduces turbulent airflow and greatly improves air utilization efficiency. The integrated full-metal duct shell and high-strength aluminum alloy hub provide outstanding structural rigidity, effectively resisting deformation and high-speed vibration during long-duration intensive flights. It perfectly solves common defects of ordinary plastic EDFs, including easy deformation, loud noise and severe power loss.

Powered by a premium brushless motor with stable 640KV parameters and 12S high-voltage compatibility, this unit outputs stable thrust over 8.6kg with a peak thrust of more than 10kg. It delivers linear and responsive power output with low heat generation and minimal energy consumption, significantly extending the overall service life of the propulsion system. The stable working speed ranges from 18,000RPM to 22,000RPM, ensuring stall-free and jitter-free high-speed flight while restoring authentic jet engine sound and realistic flight experience.

In terms of compatibility, the 120mm metal EDF supports 1:8 to 1:10 large-scale RC jet models and heavy fixed-wing aircraft. It is widely applicable for model upgrades and customized DIY jet projects. The standardized forward and reverse blade assembly allows easy installation and simple debugging, requiring no complex modification for quick assembly and adaptation to various airframe structures.

Every unit undergoes strict dynamic balance calibration to eliminate high-speed shaking and ensure stable flight posture in complex outdoor environments. With excellent dust resistance and anti-interference performance, it balances exquisite appearance and practical flight performance, making it the preferred upgrade power system for high-end simulated jet models.Meanwhile, orders for the 120mm EDF have been delivered ahead of schedule, and customers are highly satisfied with our lead‑time performance.

In the future, we will continue to focus on the R&D and iteration of RC aircraft power systems and accessories, including ducted fans, brushless motors and retractable landing gears. We will keep launching high-performance and cost-effective products to provide reliable one-stop solutions for global RC hobbyists and professional model builders.
