I would like some input as well and choose not to start a new thread....
I recently purchased a 22 YO RV-3, 0320A1A. It has a small 62" prop on it now, pitch and manufacturere unknown but the previous pilot/owner/builder liked this prop. I also have a Pacesetter 68-66 and a Sterba Experimental 68-72. 68 inches looks like the right prop but would like other input on which to use. Yes I know Pacesetter is out of business however this is the best looking prop. All three have spinner gouges around the hub.
