Description

The HappyModel EX1404 3500KV brushless motor delivers high thrust-to-weight performance in a micro form factor. Its 9N12P stator-magnet configuration ensures efficient power transfer and smooth rotational characteristics, minimizing cogging for responsive throttle control in acrobatic flight.

Engineered with a lightweight 8.7-gram construction, this motor reduces overall drone mass to enhance flight efficiency and agility. The 1.5mm hardened steel shaft provides a robust mounting point for micro propellers, ensuring reliable operation during high-G maneuvers and rapid direction changes typical in FPV freestyle and racing.

Key Features

  • Optimized KV Rating: 3500KV winding provides an ideal balance of torque and RPM for 3-4S LiPo setups on micro frames.
  • Micro-Stator Design: 1404 stator size (14mm diameter, 4mm height) packs significant electromagnetic force into a minimal footprint.
  • Precision-Balanced Bell: Dynamically balanced rotor bell reduces vibrations for cleaner FPV video feed and extended bearing life.
  • High-Temp Windings: Copper windings with high-temperature enamel insulation resist thermal breakdown during sustained high-current operation.
  • Dual-Ball Bearing Support: Incorporates two shielded ball bearings for smooth, low-friction rotation and enhanced shaft stability.
  • Lightweight CNC Aluminum: Motor bell and base are machined from aluminum alloy, maximizing strength while minimizing rotational mass.

Applications

  • Ultra-lightweight 3-inch and 3.5-inch toothpick FPV quadcopters for freestyle and racing.
  • High-performance 2.5-inch micro drones requiring aggressive throttle response on 3S or 4S power.
  • Compact long-range micro builds where low weight and high efficiency are critical for flight time.
  • Micro CineWhoop platforms designed for smooth, controlled aerial footage with smaller propellers.
  • Experimental and DIY micro drone projects needing a reliable, powerful motor in a sub-9g package.

Frequently Asked Questions

What is the recommended battery voltage for the EX1404 3500KV motor?

The EX1404 3500KV motor is optimized for 3-cell (3S, 11.1V) to 4-cell (4S, 16.8V) LiPo batteries. Using it within this range ensures optimal performance, thermal management, and motor longevity. Exceeding 4S voltage may risk overheating and premature failure.

What size propellers are compatible with this 1404 motor?

This motor is designed for micro propellers, typically in the 2.5-inch to 3.5-inch diameter range, with pitches between 2.5 and 3.5. Common compatible props include the Gemfan 3018, 3020, 4024, and similar tri-blade or bi-blade designs for micro drones. Always test for amp draw and temperature with your specific setup.

What is the mounting hole pattern for the HappyModel EX1404?

The EX1404 uses a standard M2 mounting hole pattern with a 9mm bolt circle diameter (BCD). This is the typical pattern for 1404-class motors and is compatible with most micro drone frames designed for this stator size. Use M2 x 5mm or M2 x 6mm screws for secure attachment.

Can I use this motor with a 20A or 25A micro ESC?

Yes, a 20A to 25A Electronic Speed Controller (ESC) is generally sufficient for the EX1404 3500KV motor under normal micro drone loads. Ensure the ESC firmware (e.g., BLHeli_S, BLHeli_32) supports the motor's KV and that your battery and propeller combination does not cause the motor to exceed the ESC's current rating during peak throttle.
