30mm Mini EDF Ducted Fan — 6 Blades (Brushed, 1S)
Features: Ducted fan with Brushed motor, easy to install, and built with high-quality materials for longer life and better efficiency. This compact EDF is suitable for small RC jet builds where space is limited. The 6-blade design provides reliable thrust for light jet configurations and beginner-friendly setup.
30mm Mini EDF Ducted Fan — 6 Blades (Brushed, CW)
Features: Brushed motor with straightforward installation. Made of durable materials for extended life and improved efficiency. The CW variant pairs with reversible propulsive direction needs and provides a simple drop-in for small foam jets.
40mm 12-Blade EDF Ducted Fan — Brushless (3S/4S)
Features: Premium brushless outrunner 1413-KV5000 motor, compatible with 3S/4S LiPo packs. The housing and blade surfaces have a matt finish for a premium look. Max thrust ranges from 360g to 500g depending on configuration, with recommendations for a 20A ESC. This option suits mid-sized jets seeking strong performance and smoother operation under load.
64mm 12-Blade EDF — Brushless (6S)
Features: 64mm EDF with 2840-KV2300 brushless outrunner, designed for 6S operation and high thrust up to 1800g. The assembly emphasizes aesthetic CNC spinner detailing and a matt blade finish. A 50A ESC and 6S LiPo are typical recommendations for peak performance and durable, continuous operation.
70mm 12-Blade EDF — Brushless Inrunner (6S)
Features: 70mm EDF with brushless inrunner 2860-2200KV for 6S packs, delivering up to 2400g of thrust. The laser-etched spinner and matt finish on the housing provide a robust, high-end appearance. The package is designed for larger jets requiring strong, sustained power and balanced operation.
Buying Guide
Key considerations when choosing an EDF for a model jet include size, motor type, battery compatibility, and mounting compatibility. Larger diameter fans generally deliver higher thrust, but require stronger ESCs and power systems. Brushless outrunner motors tend to offer higher efficiency and cooler operation under load than brushed units. Consider your airframe weight, flight goals (sport, scale, or 3D), and the available space for the EDF unit and battery. Ensure the ESC rating matches or exceeds the motor’s maximum current draw, and verify that the power system elements are compatible with your airframe’s weight and center of gravity. For large jets, a 6S LiPo battery is common, while smaller models may use 1S or 3S configurations. Also assess cooling needs, as sustained high throttle can heat the motor and ESC.
Performance perspectives vary: brushless outrunners generally provide higher thrust and efficiency, making them suitable for powerful jets or larger airframes. Inrunner motors, while capable, may run hotter under heavy loads and are often paired with sizable fans for consistent thrust. Blades count and design influence thrust stability and noise; more blades can improve thrust at lower RPM but may add weight and drag. Material quality, CNC finishing, and blade balance affect flight smoothness and durability. Finally, assess your mechanical installation—mounting holes, airflow direction (CW vs CCW), and compatibility with your radio system and throttle curve.
