After a year on backorder I just installed the Catto 74X50 3 bladed propeller on my new SS. Made the first flight this morning. Much smoother running. Prop has not been dynamically balanced. It is so smooth, I may not need it.

Need more flights to evaluate the impact on climb performance. On this first flight there was 3 mph increase in IAS cruise speed 44% power, sea level and 65F.

This prop just looks right on the CC SS.
