EMAX brushless motors are suitable for a wide range of hobby, engineering, and custom motion-control applications. They're ideal for high-speed propulsion, precision motion control, custom cooling fans, gimbals, 3D-printed mechanisms, and STEM or engineering prototypes.
EMAX ECO Micro Series 1404 3700KV Brushless Motor
The EMAX ECO Micro 1404 3700KV is the lower-KV variant of the 1404 micro brushless motor — tuned for 3S builds and larger prop diameters in the 3–4 inch range where torque and efficiency matter more than raw top-end RPM. The larger 1404 stator delivers more thrust than the 1106 at the same prop sizes, making it the right choice for heavier micro builds or pilots who want more punch on 3S. The 9x9mm mounting pattern fits the most common micro quad frames.
1404 stator, 3700KV — lower-KV for 3S builds with 3–4" props
More torque than 1106 — larger stator for stronger thrust and efficiency
9x9mm mounting pattern — fits the most common micro quad frames
8.6g (w/o wire) — lightweight for a 1404 stator
1.5mm prop adapter shaft — standard micro motor prop fitment
The torque-focused choice for 3S micro builds running 3–4 inch props. Also suitable for custom motion-control applications, gimbals, and STEM engineering projects.
