Gemfan 1219S Ultra-Lightweight 31mm 3-Blade Tiny Whoop Propeller
The Gemfan 1219S is engineered for micro drone pilots looking to maximize power and responsiveness without compromising flight time. By pushing the limits of modern manufacturing, Gemfan successfully reduced the center hub size while maintaining full blade thickness. This clever design slashes rotational inertia down to an absolute minimum, ensuring your Tiny Whoop snaps into turns instantly and punches out of corners with uncompromised thrust.
Key Features
- Reduced Hub Profile: Minimizes dead-weight at the center to drastically lower rotational inertia and quicken throttle response.
- High-Pitch Authority: A 1.9-inch pitch paired with a 1.2-inch diameter provides exceptional top-end speed and vertical pull on 1S power.
- Uncompromised Strength: Retains full structural blade thickness despite the diet, ensuring durability against gates and indoor obstacles.
- Featherlight Mass: Weighing just 0.18 grams, it reduces strain on micro bearings and maximizes overall energy efficiency.
- Vibrant Color Selection: Available in multiple translucent color options to easily customize your micro fleet.
