I want to replace my 2600 RPM Sensinich on my O-320 RV-4 for more speed and a smoother ride.
I can't decide between the Catto 2-blade or the Whirlwind GA. Does anyone have any real world experience and numbers between the 2? The Catto is known in our community and smooth. The Whirlwind is adjustable but it has moving parts. Price is about the same.
I've searched other threads but can't find anything specific to compare the 2 props. Any thoughts would be greatly appreciated.
