Gemfan 8145 PC 3 Blade Prop (1CW + 1CCW)

The Gemfan 8145 is a 8-inch tri-blade propeller specifically designed for high-altitude and plateau drone operations. Constructed from durable PC material, it features a 4.5-inch pitch, 205.74 mm diameter, and weighs 16.5 g. Its large size, wide blades, and high pitch provide sufficient thrust and efficient lift in low air density environments. A specialized surface treatment with a frosted front and glazed rear enhances stability and reduces the likelihood of loss of control at high RPM. Compatible with 5 mm motor mounts and recommended for 2808 900KV-class motors. Available in Black.
