Gemfan Flash Series 5152 Bi-Blade props deliver fast acceleration, provide great flight feel across the entire throttle range and thanks to their winglet tips also maintain a high level of efficiency.
These are the bi or twin blade versions of the original 5152 Triblade prop. Bi-blade propellers are still a favorite with pilots whom prefer better efficiency and slightly higher top speeds on fast and long courses. The bi-blades also feature an improved hub design that improves their durability.
