RVPROP 10 X 4.7 Slow Flyer CF Multirotor Propeller CW & CCW Propeller Set: 1. Higher Efficiency. The technology that goes into advanced profile design produces more speed from the same amount of thrust due to less inertia on the blade. Lightweight molded cross-weave carbon fiber reduces rotating mass for higher output and longer life. The cork wood sandwich construction lends this CF prop to higher strength than other carbon fiber propellers. This allows for greater loads, prolonged flight times, and longevity at maximum RPMs.2. Greater Stability. The CF propeller’s dynamic balance design is engineered specifically for multicopters. The enhanced stiffness is beneficial in controlling excess vibration as well as enhancing aerodynamic efficiency through the use of thinner cross sections. Computer-optimized design gives these props a thinner profile, which means more “bite” with less noise. Reinforcing fibers help maintain true, constant pitch at any RPM. Freebird CF propellers come pre-balanced from tip to tip, accentuating your multicopter’s stability and agility.The end result is better flying performance!RVPROP 10 X 4.7 Slow Flyer CF Multirotor Propeller CW & CCW Propeller Set Spec:Diameter: 10 inchesPitch: 4.7 inchesGood for the Slow Flyers RVPROP 10 X 4.7 Slow Flyer CF Multirotor Propeller CW & CCW Propeller Set Pictures:[img-3024-left-thickbox_default][img-3025-left-thickbox_default] [img-3026-left-thickbox_default]
