Gemfan 1811-3 Ultralight 45mm 3-Blade Micro Propeller
The Gemfan 1811-3 represents a massive leap forward in micro propeller engineering. By shedding 25% of its weight compared to older models, it slashes rotational inertia down to an absolute minimum. This substantial reduction in lag delivers instantaneous throttle transients and silky-smooth power delivery, giving micro pilots the crisp response and control authority needed for technical flying.
Key Features
