Key Applications and Projects

• Scale RC Jets: A perfect drop-in upgrade or replacement power system for standard 64mm class foam RC jets (e.g., Freewing, FMS, or Arrows models).

• Custom Hovercrafts: Using the immense air volume generated by the EDF to inflate the skirt of a high-speed DIY RC hovercraft.

• Thrust-Vectoring VTOLs: Mounting EDF units on pivoting servos to create experimental Vertical Take-Off and Landing aircraft.

Unlock New Capabilities (Project Evolution)

• The Twin-Engine A-10 Warthog: Single-engine jets are fun, but twin-engine jets are spectacular! Because this unit is specifically configured for Clockwise (CW) rotation, you can pair it perfectly with its Counter-Clockwise (CCW) counterpart. By mounting a CW fan on the right wing and a CCW fan on the left wing of a custom twin-engine jet, the rotational torque of the spinning motors perfectly cancels each other out. This gives you absolute, arrow-straight flight characteristics and double the thrust for massive, high-speed loops!

FREQUENTLY ASKED QUESTIONS (FAQ)

1. What does "64mm" refer to? It refers to the internal diameter of the duct where the fan blades sweep. It is a standard size classification for RC jets.

2. What is the actual outer diameter of the housing? The outer diameter of the main cylindrical housing is 69.8mm.

3. What is the diameter of the intake lip? The flared bell-mouth intake ring has an outer diameter of 79mm.

4. What is the maximum thrust this EDF produces? On a fully charged 3S battery (12.4V), it produces up to 782 grams of thrust.

5. What size Electronic Speed Controller (ESC) do I need? Because the motor pulls a maximum of 42 Amps at full throttle, you need a minimum of a 50A brushless ESC, though a 60A ESC is highly recommended for safety headroom.

6. What size battery is best for this 4000KV motor? This motor is highly optimized for 3S (11.1V) LiPo batteries. A 3S 2200mAh 40C or higher battery is the sweet spot for thrust and weight.

7. Can I run this on a 4S (14.8V) battery? While the title mentions 4S, a 4000KV motor will spin extremely fast on 4S and likely pull well over 60+ Amps, risking a stator burn-out. We strongly advise sticking to 3S based on the manufacturer's 12.4V testing chart.

8. How many blades does the fan have? It features an 8-blade rotor design.

9. What does "CW" mean? CW stands for Clockwise. It indicates the aerodynamic pitch of the blades requires the motor to spin clockwise to produce forward thrust.

10. Do I need to assemble the motor into the housing? No, the motor is pre-installed, and the rotor is dynamically balanced at the factory.

11. Do I need to solder the connectors? No, the three motor phase wires come pre-soldered with standard gold bullet connectors.

12. Why does it have an extra plastic ring? That is the intake lip. It smooths turbulent air entering the fan. You keep it on for external mounting, or remove it if installing the EDF deep inside a foam jet fuselage.

13. How do I connect the 3 wires to my ESC? Plug the three bullet connectors into the three matching ports on your brushless ESC. The order does not initially matter.

14. What if the fan blows air out the front instead of the back? If it pushes air the wrong way, the motor is spinning backwards. Simply unplug any two of the three bullet connectors from the ESC and swap their positions.

15. Is the motor brushed or brushless? It is a high-efficiency 3-phase brushless outrunner motor.

16. How fast does the motor spin? At 12.4V, the internal rotor reaches speeds of 37,020 RPM.

17. Can I run this on a 2S (7.4V) battery? Yes, it will safely run on 2S, but it will only produce roughly 342 grams of thrust at 21.2A, which may be too underpowered for most jets.

18. What is the total length of the unit? From the front of the intake lip to the back of the motor bullet, the total length is 73mm.

19. How is the EDF mounted into an airplane? Most 64mm foam jets feature a molded internal cradle. You simply drop the housing into the foam channel and strap it down, or glue mounting tabs to the outer 69.8mm casing.

20. Can I use this for an RC boat or hovercraft? Absolutely. EDF units provide incredible air volume and are a popular choice for custom, high-speed surface vehicles.
