This is a brief description of the sizes used on several types of planes. Please note the diameter and pitch is a recommended size and may change with your application. Also of importance is the pitch number. We use a pitch number relative to the bottom of the airfoil. Some other manufacture's numbers may be 6" different from ours, but be actually the same. Airfoils we use are different than ones used by others, so there is a difference in measurement also.
