Electric Ducted Fan XDF4008 M1908-8600KV CCW (40mm) for RC Jet Aircraft – XF4008B

EDF Fan 40mm for RC Jet Aircraft

Electric Ducted Fan XDF4008 8600KV CCW

The EDF Fan 40mm is a compact power system designed specifically for small and mid-size RC jet aircraft. To begin with, it combines a high-speed 8600KV brushless motor with a precision ducted fan assembly. As a result, RC jets achieve improved acceleration and more efficient airflow management. Moreover, the optimized rotor design ensures stable thrust delivery during high-speed maneuvers, thereby enhancing overall flight performance.

In addition, pilots can explore our complete range of

Electric Ducted Fan (EDF) Systems
to match different aircraft sizes and thrust requirements. This allows builders to select the most suitable propulsion setup for their specific RC jet configuration.

High-RPM 8600KV Motor Performance

In practice, the 8600KV motor operates efficiently on 2S or 3S LiPo batteries. Therefore, pairing it with a suitable

Electronic Speed Controller (ESC)
ensures consistent and reliable power delivery. Consequently, thrust output remains smooth and responsive even at high RPM levels. Furthermore, this stability helps maintain better in-air control during aggressive throttle changes.

Complete 40mm EDF Fan Assembly

For convenience, this EDF unit comes fully assembled and dynamically balanced. As a result, installation becomes quick and straightforward. Additionally, vibration remains minimal during operation. Because of the pre-balanced rotor system, long-term durability improves while mechanical stress decreases.

Counter-Clockwise (CCW) Rotation

During setup, the CCW rotation matches many common EDF jet configurations. Therefore, compatibility improves with standard RC flight control systems and ESC programming. In addition, airflow direction remains optimized for jet-style fuselage designs. As a result, aerodynamic efficiency increases during forward flight.

Lightweight and Efficient Design

Equally important, the lightweight shroud improves the overall power-to-weight ratio. Consequently, aircraft handling becomes more responsive and agile. At the same time, structural efficiency supports smoother airflow through the duct. Ultimately, this design works well for foam EDF jets as well as custom scratch-built aircraft.
