Gemfan 9x4.5 Reverse Glass Filled

This is the glass 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 9" props have a 6mm hole in the front and a 8mm hole on the back that fits one of the included 3mm, 4mm, 5mm, or 6mm adapter rings.
