The 12 x 4.5 Inch Multi-Rotor Propeller is a lightweight, high-RPM option designed for quadcopters and other multi-rotor aircraft. Part of APC's MR (Multi-Rotor) line, these props bridge the gap between Thin Electric and Slow Flyer designs, delivering a lighter build than Thin Electric props with higher RPM capability than Slow Flyers. Built for multi-rotor use, this prop delivers responsive lift across a range of speeds. Maximum RPM is calculated as 105,000 divided by the prop diameter in inches; for a 4.5-inch diameter that works out to about 23,300 RPM. This makes it a versatile choice when a balance of speed and efficiency is desired in multi-rotor configurations. Show more
