330-Aerobatic

This is the perfect propeller for any primary to unlimited aerobatic performer with an angle valve IO-540.

Performers such as Rob Holland https://www.ultimateairshows.com/ choose Whirlwind Propellers.

The 330 -AC series propeller platform is designed for aggressive aerobatic flight needs, Big Low speed thrust to fly off the top of any maneuver and increase hang time on the vertical up line for that perfect hammer head or humpty.

The wide chord gives unparalleled low speed performance while the highly swept tip lowers high speed drag and lowers the noise signature. This 77″ and 78″ diameter, two and three blade Carbon Fiber composite blades, features electro-formed nickel leading edge shields, and a one piece aluminum hub. Each propeller comes with a composite spinner that is ready to fly, easy to install, and finished with a white primer ready for paint.

The 330 Series is available in a standard or counterweighted configurations.

This propeller uses engine oil and a governor to hydraulically control pitch. Standard configurations are compatible with a standard “pressure to increase pitch” governor with a max relief pressure of 330 psi while counter-weighted configurations are compatible with “pressure to decrease pitch” governor with a max relief pressure of 330 psi.
