The new Sensenich cartridge system allows the pilot to select whether the blades are set to flat pitch (high rpm) to shorten take off runs or for coarse pitch (low rpm) to increase cruise speeds.
The blades are of hollow composite construction and feature a bonded metal leading edge. This construction technique–also known as internal pressure molding–lessens the overall weight of the propeller system. The weight of the propeller for the O-200 is 17 pounds.
These design features are also being implemented on propellers designed for the Continental IO-240 and the Lycoming O-235 engines, which are slated for release later in 2008. Retail price for the propellers is $3,195. A video of the pitch change process is available on the Sensenich Web site.
