The Emax ECO II 2004 2000KV is a high-performance cinewhoop motor, redesigned from the ground up with a more durable, rounded bell and upgraded magnets. Built for 4-6S LiPo power and matched to 3.5-inch propellers, it delivers a strong balance of torque, smoothness, and crash durability — exactly what cinewhoop flying demands.
Why choose the ECO II 2004 2000KV for cinewhoops?
Cinewhoop flying means tight proximity, frequent prop strikes, and a need for smooth, controllable power delivery rather than outright speed. The ECO II’s upgraded N52SH arc magnets tighten the air gap over the previous N48 magnets, giving crisper throttle response without sacrificing the smoothness needed for cinematic shots. The redesigned, thicker-reinforced bell adds real durability for the inevitable bumps and clips that come with flying close to walls, people, and obstacles. Pair it with our flight controller and ESC range for a complete cinewhoop build.
This listing is for the 2000KV winding — matched to 3.5-inch cinewhoop propellers on 4-6S LiPo.
Key features
Upgraded N52SH arc magnets
Stronger curved arc magnets create a tighter air gap than the outgoing N48 magnets, resulting in more torque and noticeably crisper, more controllable throttle response — ideal for precise cinewhoop manoeuvring.
Redesigned reinforced bell
The all-new rounded bell architecture adds thicker material at critical stress points, improving durability against the frequent light knocks and prop strikes typical of cinewhoop flying.
Mirror-polished finish
A fully mirror-polished surface gives the motor a premium look while also helping resist surface wear over repeated use.
Precision NSK bearing
A precision NSK bearing keeps the motor running smoothly with reduced vibration, supporting cleaner gyro data and stable, jitter-free footage.
