Product Details
Gemfan 1219S 31mm Tri-Blade Propellers – Ultralight Micro Whoop Performance
Push the boundaries of indoor flight with the Gemfan 1219S 31mm Propellers. Engineered specifically for the "Tiny Whoop" and micro-drone class, these propellers are a masterclass in miniaturized aerodynamics. Weighing an incredible 0.18g, they provide the instantaneous throttle response and "floaty" feel required for technical indoor racing and precision proximity flying.
Crafted from high-tensile Polycarbonate (PC), the 1219S is designed to survive the inevitable bumps against walls and gates while maintaining its rigid airfoil shape. With a 1.9-inch pitch, these blades offer high-end speed without sacrificing the low-end grip needed for recovering from power loops.
Key Highlights:
Ultralight Agility: At just 0.18g, these are among the lightest 31mm props on the market, significantly reducing rotational inertia for lightning-fast motor RPM changes.
Micro-Motor Optimization: Featuring a 1mm shaft mount, these props are the perfect companion for high-KV micro motors like the 0702 or 0802 series, ensuring a snug, vibration-free fit.
High-Efficiency 3-Blade Design: The tri-blade configuration provides a smooth, linear power curve and quieter operation compared to bi-blade alternatives, perfect for "stealthy" indoor sessions.
Durable & Resilient: The PC material is flexible enough to bend rather than snap on impact, protecting your motor shafts from damage during crashes.
Sleek Clear Gray Finish: The low-profile "Clear Gray" aesthetic complements any micro-frame build while remaining visible enough for easy pre-flight inspections.
Technical Specifications
Pro-Tip for Whoop Pilots:
Correcting the Specs: While the original listing mentioned 2207 motors, these 31mm props are strictly for Micro/Tiny Whoop motors (like 0702 or 0802). Pairing these with a lightweight 65mm frame will give you the best power-to-weight ratio for tight indoor tracks!
Partsbaba Authenticity Guarantee: All Gemfan products supplied are 100% genuine. We offer a 14-day replacement warranty against manufacturing defects, so you can tune your micro-drone with total confidence.
