Description

The RS1102 KV13500 motor from HappyModel is engineered for micro FPV platforms requiring high rotational speed and minimal mass. Its compact 15x15mm stator dimensions house a 9N12P magnetic configuration, delivering the torque necessary for rapid acceleration while maintaining compatibility with lightweight 2S and 3S power systems.

Constructed with a dual-bearing support system, the motor minimizes radial play and vibration, contributing to smoother video feed and more predictable flight characteristics. The 1.5mm shaft diameter is standard for micro prop adapters, ensuring secure mounting for propellers up to 66mm in diameter. This motor is a direct-fit upgrade for models like the Sailfly-X and is the original equipment for the Mobula7 HD, providing a reliable foundation for high-performance micro quadcopters.

Key Features

  • World's lightest 1102 brushless motor design at 2.8g, maximizing thrust efficiency.
  • High-speed 13500KV winding optimized for 2S-3S LiPo voltage ranges (7.4V-11.1V).
  • Dual-shielded ball bearing construction reduces friction and ensures long-term rotational stability.
  • Hardened 1.5mm steel shaft resists bending under high-RPM loads and impact.
  • 9N12P (9 Stator Teeth, 12 Magnet Poles) configuration for smooth rotation and efficient power delivery.
  • Compact 15mm stator diameter and height fits tightly into lightweight micro and whoop-style frames.
  • Ideal for 75mm-85mm whoop builds on 2S-3S and optimal for 66mm ductless micro racing frames.

Applications

  • Ultra-lightweight 2S-3S micro racing drones and ductless 66mm 'toothpick' frames.
  • Direct upgrade or replacement for HappyModel Sailfly-X, Mobula7 HD, and similar micro whoops.
  • High-speed 75mm to 85mm whoop builds requiring aggressive throttle response.
  • Experimental micro cinewhoop platforms where minimal weight is critical for flight time.
  • Lightweight FPV drone builds targeting sub-100g all-up weight (AUW) categories.

Frequently Asked Questions

What is the recommended battery voltage for the RS1102 13500KV motor?

The RS1102 13500KV motor is optimized for 2S to 3S LiPo battery packs, operating within a voltage range of 7.4V to 11.1V. Exceeding 3S (12.6V) is not recommended as it may cause excessive current draw, overheating, and premature failure of the motor or ESC.

What size propellers are compatible with this motor?

This motor is compatible with micro propellers ranging from 40mm to 66mm in diameter. For 2S setups, larger props within this range can be used. For 3S power, smaller, lower-pitch props (e.g., 40mm-55mm) are recommended to manage current draw and prevent overheating while maintaining high RPM.

Is this motor a direct replacement for the Mobula7 HD?

Yes, the HappyModel RS1102 13500KV with a 1.5mm shaft is the original equipment motor for the Mobula7 HD and is a direct physical and electrical replacement. Ensure your flight controller ESC supports the high KV rating and that you use the correct motor rotation (CW/CCW) for your build.

What is the significance of the dual-bearing design?

The dual-bearing design utilizes two shielded ball bearings on the motor shaft. This configuration provides superior radial support, minimizing shaft wobble and vibration at high RPMs. This results in smoother operation, reduced wear, longer motor life, and cleaner FPV video footage by mitigating high-frequency vibrations.
