Diameter

The Propeller Diameter is equal to the diameter of a circle drawn by the propeller tips during rotation. For 2 blade propellers the diameter is equal to the length of the propeller from tip to tip. For 3 and more blades, the diameter can be derived by 2x the length of the single blade (from tip to center).

Pitch

The Pitch is defined as the distance the propeller would travel forward in one revolution if it was moving through a soft solid (like a screw through wood).

Normal (N) - Tractor

also known as standard, direction of rotation is established when a propeller is rotating counterclockwise (CCW), as seen by an outside observer standing in front of the propeller and looking at it.

Reverse (R) - Pusher

also known as P-type, direction of rotation is established when a propeller is rotating clockwise (CW), as seen by an outside observer standing in front of the propeller and looking at it.

Shaft Diameter

The shaft diameter is equal to the size of the orifice at the center of the propeller where the motor shaft is connected. Since shaft diameters differ from engine to engine, some propellers are manufactured with 2 shaft diameters (pre-drilled on the back) for easy adaptation. Some propellers, as the 3 Blade and Electric Only Series, include Adaptor Ring Sleeves which can adjust the the shaft diameter to several inch or mm sizes.

Hub Thickness

The Hub Thickness is usually used to determine the necessary engine shaft length so there is enough space for connecting the propeller and the cap or the spinner.
