FWIW, I bought a Catto but have not hung it yet, maybe w/in a month or so. Everything I have heard sounded very positive. It should be noted, that with my O-290-D2 I really didn't have a choice as there isn't a Sensenich sized for this engine / plane combination.

The Catto weighs about 13 pounds versus something like 40 pounds for the recommended Sensenich. I fly with several RV's with constant speed props and have no problem staying with them in cruise and in cruise climb, often with lower fuel burn for equal IAS. A plus is that there are no RPM restrictions other than a limit speed of, as I recall, 3000 RPM for my prop :-). Several RV's in this area are also using Catto three blade props and the owners are very satisfied with them. My personal observation of the three blade props is that they seem to offer better initial acceleration and climb versus the two blade and run very smooth but may not be quite as efficient in cruise. BTW, I have no connection to Craig Catto other than that I am convinced that he makes great propellers. -- Harry Crosby RV-6 N16CX, 286 hours -------------- Original message -------------- From: Ron > --> RV9-List message posted by: Ron > > Those who have experience with Cato and Sensenich two blade props, what > are your thoughts.
