Description

The HappyModel SE0702 KV28000 brushless motor is engineered for pilots demanding maximum performance from 1S-powered micro FPV drones. Its exceptionally low 1.5-gram mass allows for aggressive flight characteristics without sacrificing flight time, making it a cornerstone for ultralight whoop and toothpick builds.

Precision-wound stator coils and high-grade magnets in the 9N12P configuration ensure efficient power conversion and reliable thermal performance under sustained high-RPM loads. The motor’s design prioritizes a high thrust-to-power ratio, providing the explosive acceleration needed for technical indoor racing and responsive freestyle maneuvers.

Key Features

  • Ultra-Lightweight Engineering: At just 1.5 grams, it significantly reduces overall aircraft weight for improved agility and flight efficiency.
  • High-Speed KV Design: The 28000KV rating is specifically calibrated for 1S LiPo voltage, delivering the high rotational speed required for micro propellers.
  • Robust 9N12P Stator: This magnetic configuration offers a balance of smooth operation, torque, and long-term mechanical reliability.
  • Optimized Thermal Design: Compact construction with efficient airflow management helps dissipate heat during aggressive flight sessions.
  • Precision 1mm Shaft: Ensures secure and concentric propeller mounting for smooth, vibration-free operation.
  • Wide Propeller Compatibility: Tested and proven with popular micro propellers like the Gemfan 1219, offering flexibility for tuning thrust and efficiency.

Applications

  • Ultra-light 1S FPV Whoop builds (e.g., Mobula6/7, TinyWhoop) for indoor racing.
  • High-performance micro toothpick and freestyle drones requiring maximum thrust-to-weight.
  • Custom ultralight DIY micro quadcopters where every gram impacts flight dynamics.
  • Agility-focused indoor cinewhoop platforms for smooth, responsive camera movement.

Frequently Asked Questions

What is the recommended battery voltage for the SE0702 28000KV motor?

The SE0702 motor is specifically designed for 1S LiPo battery packs, with a nominal voltage of 3.7V. Operating it within this 1S range ensures optimal performance, efficiency, and prevents potential damage from over-voltage. Do not use it with 2S or higher voltage batteries.

What size propellers are compatible with this motor?

This motor is optimized for small, high-pitch micro propellers commonly used on 1S whoops. It has been bench-tested to deliver excellent performance with propellers like the Gemfan 1219 31mm tri-blade. It is compatible with other similar 31-40mm diameter propellers designed for 1mm shafts.

Is this motor suitable for long-range or heavy-lift micro drones?

No, the SE0702 is engineered for high-speed, agility-focused applications. Its ultra-high KV rating and minimal weight prioritize rapid throttle response and acceleration over efficiency and torque for lifting heavier payloads. It is best suited for lightweight racing, freestyle, or cinewhoop builds where low mass is critical.
