Three Blade MT Composite Propeller STC Option Approved For Three Cessna Models Flight-Resource, LLC has announced the latest enhancement to one of their many popular composite propeller upgrade STC’s. A 79” 3-blade option is now approved along with the popular 83” 2-blade configuration for all Cessna 170,172 and 175 that are powered by a Lycoming -360 series engine. “The slightly shorter 3-blade prop provides higher initial thrust making it perfect for applications where short take off and best climb are required," said Flight-Resource’s John Nielsen. "At the same time, the design reduces drag such that there is no cruise speed loss. The smaller diameter also provides a bit more ground clearance.” Nielsen added, “The light weight and composite structure benefit operators with turbine smooth operation and elimination of RPM restricted ranges”. Approval extends to all Float and Ski operations. Flight-Resource is the exclusive supplier of this particular enhancement and is providing a trade program for those currently running the 2 blade MT, wishing to move to the new 3-blade model.
