Description

The HappyModel EX1404 KV3500 brushless motor is engineered for high-performance micro and toothpick-class FPV drones. Its 3500 KV rating provides the high rotational speed necessary for snappy throttle response and agile maneuvering on 3S and 4S LiPo power systems. The motor’s lightweight construction, at only 8.7g, minimizes overall build weight to enhance flight efficiency and agility.

Built with durability in mind, it incorporates a robust 1.5mm steel shaft and high-quality NMB double ball bearings to reduce friction and ensure consistent, long-lasting performance. The 9N12P (9 stator teeth, 12 magnet poles) electromagnetic design contributes to smooth operation and efficient power conversion, making it an ideal choice for pilots seeking a balance of power, weight, and reliability for freestyle and racing applications.

Key Features

  • High-KV 3500 design optimized for 3S and 4S LiPo voltage ranges.
  • Minimal weight of 8.7 grams for superior flight dynamics and efficiency.
  • Durable 1.5mm shaft ensures compatibility with standard micro propellers.
  • Premium NMB double ball bearings for reduced mechanical wear and vibration.
  • 9N12P internal motor layout for smooth torque delivery and efficient operation.
  • M2 mounting holes with a 9mm bolt pattern for secure installation on micro frames.
  • Capable of producing up to 327 grams of maximum thrust for aggressive flight profiles.

Applications

  • High-performance 3-inch toothpick FPV drones for racing and freestyle.
  • Lightweight 2.5-inch to 3.5-inch micro drone builds requiring aggressive throttle response.
  • Compact cinewhoop or micro freestyle quads operating on 3S or 4S LiPo batteries.
  • Agility-focused builds where minimizing rotational mass and total weight is critical.

Frequently Asked Questions

What is the compatible voltage range for the HappyModel EX1404 3500KV motor?

The HappyModel EX1404 3500KV motor is designed for use with 3S (11.1V) and 4S (14.8V) LiPo batteries. Its high KV rating is optimized for these voltage ranges to provide the high rotational speed necessary for agile micro and toothpick drone performance. Exceeding 4S voltage is not recommended.

What propeller sizes are recommended for this 3500KV motor?

This motor is best paired with small, lightweight propellers typical for 2.5-inch to 3.5-inch micro drones, such as Gemfan 3018 or 4024 tri-blade props. The high KV rating works well with lower-pitch, smaller-diameter props to generate responsive thrust without overloading the motor or ESC on 3S or 4S power.

What is the mounting hole pattern for the EX1404 motor?

The HappyModel EX1404 motor features an M2 mounting hole pattern with a 9mm bolt circle diameter (9mm M2). This is a standard mounting pattern for many micro and toothpick-sized FPV drone frames, ensuring easy and secure installation.
