9x4.5 Multi Rotor Propeller (APC09045MR)

The 9x4.5 Multi Rotor Propeller (APC09045MR) is specifically designed for multi-rotor applications such as quad-copters. Crafted by APC, these propellers strike a perfect balance between Thin Electric propellers and Slow Flyer propellers. The ‘MR’ series is lighter than traditional Thin Electric models, while offering a higher RPM capability compared to Slow Flyers.

For optimal performance, APC suggests a maximum RPM of 105,000 divided by the prop diameter in inches for their multi-rotor props, ensuring that you achieve the best possible results in your aerial endeavors.
