EMAX ECO II 2004 Brushless Motor

The EMAX ECO II 2004, offered in 1600KV, 2000KV, 2400KV and 3000KV windings, is a lightweight brushless motor engineered for 4-inch micro long-range platforms, ultralight 5-inch freestyle drones, and powerful cinewhoops. By utilising a wider 2004 stator, this motor delivers superior torque and throttle authority compared to smaller 1404 or 1505 alternatives, whilst maintaining a low footprint for sub-250g builds.

Key features

• Upgraded N52SH curved arc magnets for a tighter air gap and smoother throttle response.

• Fitted with a standard 1.5mm T-mount shaft for secure propeller attachment.

• Lightweight bell design brings the total motor weight to just 16.4g with wires.

• Pre-tinned 120mm silicone wires allow direct routing to your AIO board or 4-in-1 ESC.

This 2000KV variant is heavily optimised for 6S efficiency. Pair it with 4-inch bi-blade or tri-blade propellers and a 30A+ ESC for long flight times on a lightweight cruiser, or run it on 4S for a highly responsive cinewhoop.
