Gemfan Flash 6042 2-Blade Propellers - 4-Pack With 7.5mm Hub For Racing Drones

About This Product

Drone racers, listen up! These Gemfan Flash 6042 propellers are specifically engineered for high-speed performance where every millisecond counts. The 2-blade design with those inverse tips isn't just for looks - it actually reduces blade tip vortex and drag, giving you faster response times and better efficiency. Made from durable PC material, these props can handle some impacts without shattering immediately, which is important when you're pushing your limits on the race course. The 6042 size (6.0x4.2) works great with 2407-2408 motors, and the 7.5mm hub thickness ensures a secure fit without wobble. Each set comes with 2 clockwise and 2 counter-clockwise props, so you're ready for a full quadcopter setup. What's really impressive is the engineering behind these - Gemfan uses CATIA modeling and Ansys Fluent software to optimize the airfoil design, testing factors like surface pressure, lift force, and torque to create props that actually make a difference in race performance. The lightweight design means smaller moment of inertia, so your drone responds quicker to throttle changes and directional adjustments. Whether you're competing seriously or just want to experience that racing performance in your freestyle flights, these props deliver noticeable improvement over standard options. They balance well right out of the package, which saves you time during setup. If you're tired of props that flex too much under load or don't give you that instant throttle response you need for technical courses, the Flash series is definitely worth trying. They're that perfect balance of durability and performance that serious racers look for.
