The Gemfan 1219s is an ultra-light 31mm propeller engineered for high-performance Tiny Whoop drones. With a 1.2-inch diameter, 1.9-inch pitch, and weighing only 0.18g, it pushes the limits of lightweight prop design. By reducing hub size while maintaining blade thickness, the 1219s achieves an extremely low moment of inertia, delivering faster response and smoother control without sacrificing power compared to the original 1219.
Designed for 0702–29000KV motors, the 1219s is ideal for competitive micro whoop builds where every milligram counts.
