Get your micro ripper back in the air with the Happymodel EX1103 11000KV Motor. Specifically designed as the stock replacement for the Happymodel Bassline 2S, this high-performance brushless motor is also an excellent choice for any custom 2-inch toothpick or lightweight whoop build. Available in both CW (Clockwise) and CCW (Counter-Clockwise) configurations, you can pick the exact match for your quad.

High-RPM 2S Power

With a screaming 11000KV rating, this motor is optimized to deliver incredible punch and top speed on 2S LiPo batteries. It strikes the perfect balance between efficiency and raw power, making it ideal for aggressive freestyle in tight backyard spaces.

Compact & Lightweight

Weighing in at just 3.8g, the EX1103 helps keep your All-Up Weight (AUW) low, which is critical for micro drone agility. The motor features a durable 1.5mm smooth shaft and a sleek red-and-black bell design that looks as good as it performs.

Choose Your Rotation

Please select your desired rotation from the dropdown menu:

• CW (Clockwise): Typically used for Front Left and Rear Right motors (in standard Betaflight configuration).

• CCW (Counter-Clockwise): Typically used for Front Right and Rear Left motors.

• Tech Note: Since these motors use a smooth 1.5mm shaft (no threaded prop nuts), the motors are physically identical. While you can reverse the direction of any motor electronically in Betaflight (or by swapping two wires), buying the matched rotation ensures your wire ordering matches the factory standard for a hassle-free repair.
