Description

The HappyModel EX1404 is a precision-engineered brushless motor built for the demanding requirements of modern micro and SUB250-class FPV drones. Its 14x4mm stator and 2750KV rating are optimized to provide an exceptional thrust-to-weight ratio while maintaining high efficiency on 4S LiPo batteries, enabling extended flight times for long-range and endurance missions.

Constructed with high-grade materials, including imported NMB bearings, the motor ensures reliable, low-vibration operation. The 9N12P (9 stator teeth, 12 magnet poles) configuration minimizes cogging for ultra-smooth throttle transitions, making it ideal for both cinematic cruising and precise acro maneuvers in compact builds.

Key Features

  • Optimized for 4S LiPo voltage, balancing power and efficiency for long flight times.
  • Ultra-lightweight 8.7-gram design reduces overall drone weight for improved performance.
  • High-quality NMB bearings provide smooth operation and extended service life.
  • 1.5mm shaft diameter ensures compatibility with a wide range of micro propellers.
  • 9N12P magnetic configuration delivers stable, responsive performance with minimal cogging.
  • Durable construction with high-temp magnets and windings for reliable operation.
  • Excellent compatibility with popular micro propellers like the Gemfan 4024 and 4023.

Applications

  • SUB250-gram long-range and endurance micro FPV drones.
  • Lightweight 3-inch and 4-inch micro racing or freestyle quadcopters.
  • Compact cinewhoop builds requiring smooth throttle control for cinematic footage.
  • Micro drone platforms where maximizing flight time on 4S power is critical.
