The Gemfan Flash 5152-2 Bi-Blade is built for FPV pilots who demand maximum speed with minimal power draw. Its aerodynamic two-blade profile drastically reduces drag, improving both throttle response and overall efficiency.
At just 3.8 grams per prop, it keeps motor load low — letting your drone fly longer, cooler, and faster.

The precisely balanced 4.2-inch pitch and stiff PC construction ensure smooth, consistent thrust even at high RPMs. Combined with 2205–2306 motors, this prop is ideal for lightweight, agile builds and high-efficiency setups.
