Restore the agility of your digital whoop with the Happymodel RS1102 10000KV Motor. Designed specifically as the original equipment manufacturer (OEM) replacement for the Happymodel Mobula7 O4, this motor is tuned to carry the extra weight of digital HD systems while maintaining the snappy feel of a 2S micro drone.
Optimized for 2S Power
The 10000KV rating is the “sweet spot” for 75mm whoops running on 2S LiPo batteries. It offers the perfect blend of high-end RPM for speed and low-end torque needed to recover from dives, especially when carrying the DJI O4 Air Unit.
Ultralight 1102 Stator
Weighing in at just 2.8g, the RS1102 features a compact 11mm x 2mm stator. This wide-but-flat “pancake” design provides excellent efficiency and cooling, ensuring your motors run smooth and cool even during aggressive freestyle sessions.
Versatile Micro Motor
While built for the Mobula7 O4, this motor is also an excellent choice for any custom 75mm Whoop or 2-inch Toothpick build requiring a lightweight 2S powertrain. It features a standard 1.5mm shaft, making it compatible with a vast array of micro propellers.
