Product overview
The Gemfan Flash 5152 is a two-blade polycarbonate propeller intended for mini and micro multirotor aircraft, including lightweight drones that need agility and stable control. Its physical configuration combines an approximately 131 mm (5.1 inch) diameter with a 4.2-inch pitch. The blade design targets low drag and responsive handling, while its aerodynamic profile supports predictable control. The polycarbonate construction provides impact resistance for minor collisions encountered during frequent flying, with durability described for those operating circumstances.
The propeller integrates through a 5 mm shaft hole identified as M5, supporting installation on common motors with that interface. Each pack contains two clockwise and two counterclockwise propellers, supplying four propellers as the product configuration. The 4.2-inch pitch is tuned to combine quick acceleration with sustained thrust and smooth, controllable throttle response. Weight remains unconfirmed. This is a propeller product for integration into a multirotor aircraft; the supplied configuration is a propeller pack.
