Gemfan 7037 3-Blade Propeller (Set of 4) - Black PC
by Gemfan

The Gemfan 7037 3-Blade Propeller (Set of 4) - Black PC is a professional-grade 7-inch tri-blade propeller purpose-built for the high-demand "Cinelifter" and long-range multirotor sUAS markets. Engineered to deliver a highly linear thrust curve and optimal control, it features a 7-inch diameter matched with a 3.7-inch pitch. This unique blade geometry provides sustained, heavy-lifting power and reliable static thrust during medium-to-high speed flight, making it the ideal choice for drones carrying heavy cinematic payloads, multispectral sensors, or tactical equipment.

Constructed from premium Polycarbonate (PC), this specific variant delivers an exceptional balance of flexibility, weight, and high impact resistance. The blades are designed with a wide 18.5mm width and a robust 7.0mm thick hub to minimize flexing and fluttering under the aggressive rotational torque of modern large-stator motors (such as 2807 or 2808 sizes). For university aerospace labs, robotics groups, and industrial UAV manufacturers, the Gemfan 7037 offers a highly optimized propulsion core that effectively damps out high-frequency vibrations (jello), ensuring crystal-clear video telemetry and steady autonomous flight control.
