what is meant by pitch on a propeller
Pitch is defined as the distance a propeller would move in one revolution if it were moving through a soft solid, like a screw through wood.. For example, a 21-pitch propeller would move forward 21 inches in one revolution. Think of a propeller as you would a car's axle ratio. The lower the ratio, the more pulling power from a standstill. The same is true with a prop. The lower the pitch, the better your hole-shot.
