Gemfan Flash 4052 Tri-Blade 4″ Propeller (4 Pack — 2CW+2CCW)

The Gemfan Flash 4052 Tri-Blade is a highly aggressive 4-inch propeller engineered for fast-paced micro racing and freestyle builds. Featuring a steep 5.2-inch pitch, these props deliver maximum thrust and high top-end speed, making them suited for pilots running robust powertrains (such as 1506 to 2205 motors) who prioritise raw acceleration over flight time.

• Durable polycarbonate construction withstands gate clips and moderate impacts without shattering.
• Standard 5mm hub compatible with common M5 threaded motor shafts.
• Optimised blade tips reduce drag and improve high-speed cornering stability.

Available in Ferrari Red or Clear, the Flash 4052 is ideal for heavier 4-inch frames requiring serious grip in the air. Due to the steep blade pitch, ensure your ESCs and batteries can handle the increased amp draw compared to standard low-pitch 4-inch alternatives.
