EMAX ECO 1404 Brushless Motor

The EMAX ECO 1404 brushless motor, offered here in 3700KV, 4800KV and 6000KV windings, is designed for sub-250g micro builds. Aimed at 3-inch and 4-inch ultralight toothpicks or micro long-range cruisers running 2S to 4S power (lower KV for higher cell counts), this motor delivers reliable mid-range torque while keeping current draw low for extended flight times.

Key features

• Optimised for 3-inch to 4-inch ultralight frames and micro long-range builds

• Efficient 9N12P configuration for smooth throttle response

• Standard 1.5mm T-mount shaft accepts a wide variety of micro propellers

• Lightweight design at just 8.6g to keep sub-250g builds strictly under weight

Specifications

• KV: 3700, 4800 or 6000

• Stator Dimensions: 14x4mm

• Configuration: 9N12P

• Input Voltage: 2-4S LiPo (higher-KV windings suit fewer cells)

• Shaft Diameter: 1.5mm (T-mount)
