9x4.7 Slow Flyer Propeller (APC09047SF)

APC is proud to provide a line of propellers specifically designed for Multi-Rotor applications (Quad-Copters). These propellers bridge the gap between our Thin Electric propellers and Slow Flyer propellers. The "˜MR' propellers are lighter than the Thin Electrics and have a higher RPM capability than the Slow Flyers.

APC Suggested RPM Limits: Maximum RPM=105,000/prop diameter (inches)
