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 &amp; -540 engines. The 300 Series has endured more design scrutiny and study than any other prior Whirl Wind design.<\/p><p>This extensive line of constant speed propellers can be used on all types of OEM aircraft, such as: Vans Aircraft: RV-3, RV-4. RV-6, RV-7, RV-8 &amp; RV-10, Harmon Rocket, F1 Rocket, Aerobatic Aircraft: Pitts, Extra 300, Extra 330, Edge 540, MX, S-Bach, Back Country STOL Aircraft; Cubs, Carbon Cub, Super Cubs, Mustang II, Skybolt, Epsilon TB-3 and many, many more.<br><br>Please call to check your application.
