In general, bigger props are more efficient (a 7" will be more efficient than 6", and 6" moreso than 5", etc.). These props maximize 5" builds by adding a little extra prop to get a little more thrust and speed.

The pitch (middle # when reading prop specs) represents the angle of the prop and is measured by how far forward the prop would go in one revolution (simply speaking). For instance, a 5x3.6x3 prop would travel 3.6 inches in one revolution with no other factors.

It's easiest to think of this figure as a "drive gear". The higher the pitch (or gear) the more power and top speed it will deliver, at the cost of low-end torque and response. Higher pitch props will be more efficient at higher speeds.

A lower pitched prop will be more responsive, more low-end torque, and be more efficient at slower speeds. But will have less overall power and top speed, and will be less efficient at higher speeds.
