Hartzell Propeller has received a Supplemental Type Certificate (STC) for its new lightweight Scimitar prop for all Cessna 172RG Cutlass aircraft.
The newly designed and “aggressively shaped” Scimitar swept tip aluminum compact blended airfoil two-blade propeller and light-weight carbon fiber all composite spinner assembly enhance standard-equipped propeller performance, according to company officials.

The newly engineered propeller has a globally acceptable takeoff noise profile of 84.9 dB(a), and a number of foreign STC validations are pending.
The new propeller, part of Hartzell’s Top Prop conversion program, has a 2,400-hour, six-year recommended time between overhaul. Kit pricing for the new prop, spinner and STC is $9,500.
For the STC program, Hartzell Propeller was permitted to fly a Cessna 172RG Cutlass on loan from the Aeronautics Division at Kent State University‘s College of Applied Engineering, Sustainability and Technology. The Kent State Aeronautics Program is home to the largest fleet of university operated aircraft in Ohio and is based at the Kent State University Airport in Stow, Ohio. The program has more than 500 students seeking degrees in Flight Technology, Aviation Management, Aeronautical Systems Engineering Technology, Aeronautical Studies and Air Traffic Control.

I am with Jaime how does it affect performance? As a Cutlass owner its these details that would cause me to make the change also will if out perform the Mccauley 3 blade scimitar?
So, how if any does it affect performance?
