Description
The FMS 64mm Ducted Fan System (FMSEDF004) pairs an 11-blade impeller with a 2840-KV3900 brushless outrunner to deliver efficient thrust and a refined, jet-like sound. Built around a high-strength composite duct with a CNC-machined aluminium spinner, the 135 g unit is dynamically balanced for smooth running and dependable performance on 3S power. Well suited to high-speed EDF jets and precision aerobatic platforms.

Specifications
FMS 64mm 4S 11-Blade EDF System with 2840-KV3150 Motor
Precision. Power. Perfection.
This is not just a ducted fan, t's a high-efficiency thrust system engineered for elite RC performance. Combining advanced composite construction, cutting-edge aerodynamic analysis, and precision balacing, this FMS 64mm 11-Blade EDF unit is your go-to solution for speed, sound, and sky-punching power.
Why this EDF dominates:
- Aerodynamically Optimised
Designed in collaboration with Beihang University, one of China's top aerospace institutions. Every curve and blade is shaped from deep airflow field analysis, CFD simulation, and wind tunnel data - then tested, printed, and perfected before final moulding. - Superior Build Quality
Constructed using high-strength composite material, this unit offers the optimal blend of light weight (135g) and ultra-rigid toughness. Injection-moulded for consistency and durability. - Dynamic Balance, Dialled In
The 11-blade impeller, CNC metal spinner, and tight duct tolerance ensure razor-sharp balance, eliminating vibrations and delivering jet-like sound and thrust. - Cooling Innovation
Exclusive FMS cooling channel design extends motor life and sustains high-performance output during demanding flights.
