Constant Speed Propellers

The 300 Series is an entirely new three blade propeller platform. Whirl Wind incorporated advanced engineering tools in the development of the 300 Series, including exclusive use of full solid modeling including animation, high end finite element analysis and extensive vibratory studies on a wide range of engines, including the IO-320, -360, -390 & -540 engines. The 300 Series has endured more design scrutiny and study than any other prior Whirl Wind design.
