Gemfan 1219S-3 31mm Tri-Blade Prop (4CW+4CCW)

The Gemfan 1219S-3 takes the proven 1219 platform and pushes it to the edge of micro-performance. Weighing just 0.18g, this 31mm tri-blade prop delivers exceptionally low rotational inertia for instant throttle response, sharper handling, and greater efficiency in tight flying environments.

Engineered with a reduced hub size while maintaining full blade thickness, the 1219S-3 sheds every unnecessary milligram without sacrificing power output—matching the performance of the original 1219 despite its extreme weight savings.

Optimized specifically for high-RPM micro motors such as the 0702 29,000KV, this prop excels in ultralight TinyWhoop builds where every gram counts and throttle authority is everything.
