Gemfan 8x4.5 Reverse Carbon Filled

This is the carbon filled version. These props are great for multirotor applications. Jason and Neal use the carbon filled versions on their copters as they are stiffer and work great. We offer both normal and reverse rotation for multi rotor applications, but they can also be used as counter rotating props for multi engine airplanes. The 8" props have a 5mm hole and comes with 3mm, 3.17mm, and 4mm adapter rings.
