Robin Depending on your altitude, and density altitude of the day a tip speed of 680 ft per sec could be just below or above the speed of sound. Breaking the speed of sound with a prop is a no no if you want max life from the prop, best performance, and least amount of noise; all of the above are problems encountered when a prop breaks the speed of sound at the tip or progressing down the blade.

This may help in the selection of the correct prop.
