Propeller Rotation

The direction of the rotation of a propeller is determined to be clockwise (CW) or counter-clockwise (CCW) when viewed from the air discharge side.

The dischage side is the side that the paddles are cupped.

Sandbox thinkingology: imagine standing in a sandbox and dropping the propellar face up or down on the surface of the sand. The direction of rotation is the same as the direction required to turn the propeller into the sand.
