2 Blade 70″ Alpha Series

The Sensenich “Alpha” series 2 blade prop system for the small engine market is the latest performance based design for maximum speed along with best in class cruise efficiency. This new system utilizes pitch blocks and plate hub configurations for many different applications & bolt patterns. It features a more traditional style airfoil for increased mid and top end speed while the light weight design increases the engines ability to respond faster.

This propeller runs extremely smooth due to the composite hollow construction and advanced manufacturing process.
