12x3.8 Slow Flyer Propeller (APC12038SF)

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 include a maximum RPM of 105,000 per prop diameter in inches.
