*This same type of propeller tip modification is used by Jon Sharp on his world record setting formula one racer “NEMESIS” (283.75 mph) NEMESIS has also won the formula one division of the Reno Air Race for the past several years using this same type propeller tip modification.
The reshaping of the tip reduces the tip turbulence that causes drag, making the propeller more efficient. This modification is like getting more horsepower.
Typically after modifying the tips, two inches of pitch can be added without affecting the takeoff or climb performance. The modification itself acts like adding an inch of pitch, therefore when repitching two inches it’s the same as re pitching three inches for cruise. This convert to 4 to 6 mph.
