DISC.. APR 12.5x11inch Prop. (1)
This range of propellers offer a vast range of unusual pitch’s combined with wide and narrow bladed props that suit low rpm engines, such as four-strokes that use wide blade propellers because four-strokes turn fewer rpm. The lower rpm means the air that the trailing blade is entering is less disturbed. Additionally, four-strokes have more torque than two-strokes. Because of this a four-stroke can swing a wider propeller efficiently.
High rpm engines such as two-stroke are more efficient with narrow blade propellers due to the more disturbed air caused by the higher rpm, propellers range from 4 to 19inch.
