Quiet and Smooth Operation • Complete Propeller & Spinner Package • Competitive Price

330 3B SERIES

This is the perfect propeller for a Socata TB 30 Epsilon or other high speed aircraft with an angle valve IO-540. The 330 series propeller platform is built to withstand more aggressive engines with high compression ratios. The slightly broader swept tip blade plan form has been designed for optimized blade loading on high speed platforms. This 78″ diameter, 3-bladed propeller features a “scimitar” style swept tip, Carbon Fiber composite blades, electro-formed nickel leading edge shields, and an 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.
