Anybody have any performance comparison numbers switching from the Sensenich F/P propeller to a C/S prop on their RV-9 or -9A? My project, RV-9A, came with the Sensenich F/P prop, but the engine, Mattituck IO-320, is capable of C/S by removing the CS plug and adding a governor. I know the benefits of a C/S prop but just trying to figure out if I want to make the switch while the F/P prop is still new in the box. I would love some before and after the swap performance numbers to help me justify the added costs. Thanks! Dave
