51mm 5-Blade PC Ducted Props

Compact, high-efficiency 51mm ducted propellers made from premium-grade polycarbonate (PC). Key specs include 1.9-inch pitch, 4.6mm hub thickness, 1.5mm center hole with three mounting points, and ultra-lightweight construction at just 0.996g per propeller. Fully compatible with 1204 and higher-spec micro brushless motors. Supplied as a complete set: 4 clockwise (CW) and 4 counter-clockwise (CCW) units — designed for quick, reliable replacement on FPV CineWhoop and racing platforms. The 5-blade ducted architecture delivers enhanced thrust linearity and reduced acoustic signature versus traditional open props — supporting both aggressive racing lines and smooth cinematic movement. Ideal for pilots prioritising durability, repeatability, and clean power delivery in size-constrained builds.
