30mm Mini EDF Ducted Fan With Brushed Motor (CW)
This compact 30mm EDF offers a simple entry point into ducted fan propulsion. It uses a Brushed motor paired with a 1S LiPo setup, delivering about 50g of thrust—adequate for small electric jets or park flyer models. The unit is designed for easy installation and reliable operation, with materials chosen for longevity and efficient performance. Its small footprint makes it ideal for indoors or light outdoor flights where weight and ease of mounting are critical.
30mm Mini EDF Ducted Fan With Brushed Motor (CCW)
This CCW variant mirrors the CW model, giving builders the flexibility to design dual-motor configurations with opposite rotation for balanced yaw characteristics. Like its CW counterpart, it uses a Brushed motor and a 1S battery, prioritizing ease of use and quick installation. It remains an economical option for pilots seeking to experiment with EDF propulsion on small airframes while maintaining respectable efficiency for its class.
64mm EDF Ducted Fan With Brushless Outrunner (4S)
This 64mm EDF pairs a high-performance brushless outunner with a 4S battery, delivering robust thrust up to approximately 1250g. The assembly features a laser-polished CNC spinner and a matte-finish EDF housing for a premium aesthetic. It’s designed for stable, consistent operation under load, with a focus on cooling efficiency and durability. This unit suits mid-sized to larger models where thrust, efficiency, and long service life are priorities.
EDF 70mm Ducted Fan With Brushless Motor (80A ESC, 4S)
Designed for larger scale jets, this 70mm EDF includes a high-capacity 80A ESC and a 4S setup. The unit emphasizes dynamic balance, safety features, and cooling efficiency. Its integrated banana plug soldering and adjustable low-voltage settings support reliable, safe operation in demanding flight regimes. Expect strong, responsive performance with a realistic jet sound profile, making it suitable for more serious RC jet projects and enthusiasts seeking a step-up in power and reliability.
EDF 64mm 3500KV 4S Ducted Fan (11 Blades)
This 64mm, 11-blade EDF blends a high KV brushless motor with a 4S setup to maximize thrust and speed. The unit is built with a focus on balance and stability, featuring pre-soldered banana plug connections for easy integration into ready-to-fly configurations. With a built-in protection and robust construction, it’s well-suited for pilots who want enhanced performance without sacrificing reliability in mid-sized jet airframes.
Buying Guide: Key Considerations For Choosing RC Ducted Fan Engines
- Motor Type: Brushed motors are approachable and inexpensive, ideal for beginners and simple builds. Brushless outrunners deliver higher efficiency, more thrust, and longer life, but require compatible ESCs and batteries.
- Size And Thrust: Match fan diameter to airframe weight and desired performance. Smaller 30mm units suit micro jets; 64mm and 70mm options power mid-to-large models with strong thrust.
- Voltage And Battery: 1S setups are common for tiny, easy-to-fly planes. 4S setups provide significant power for larger airframes but require careful weight management and cooling planning.
- ESC Compatibility: Ensure your ESC rating meets or exceeds the motor’s maximum current. Oversized ESCs can improve cooling and reliability but add weight.
- Cooling And Durability: Look for well-machined housings, quality bearings, and features that aid cooling during sustained flights. Durable materials extend life in field conditions.
- Balance And Installation: Dynamic balance testing reduces vibration and improves flight stability. Pre-soldered connections and ready-to-install assemblies save setup time.
- Sound And Realism: A well-tuned EDF setup provides a realistic jet sound profile, which some pilots value for immersive flight experiences.
- Weight Considerations: Heavier ducted fans demand stronger airframes and thicker batteries. Always verify weight budgets against the target model’s design specs.
- Lifecycle Costs: Brushless systems typically cost more upfront but offer lower maintenance and longer lifespans, reducing total ownership costs over time.
- Compatibility: Check that the chosen EDF unit is compatible with your model’s mounting points, spinner size, and prop-to-battery geometry to avoid interference with control surfaces or fuselage.
In summary, the options above span beginner-friendly brushed motors to high-performance brushless systems designed for more capable RC jets. Selecting the right unit depends on your airframe size, desired speed, and your readiness to manage battery and cooling requirements. Always follow manufacturer guidelines for installation and safety to maximize performance and longevity.
