My Sensinich was 79 pitch. But Catto does not use the same numbers. One would think that they would be the same (forward progress per revolution given in inches) but I guess the answer is "it depends"
Craigs numbers are lower. I flew out there and bolted on a race prop from an RV-6, flew it to gather data and Craig worked his magic. With the race prop I was climbing out at 140 mph making 1750 fpm, top speed at 7,500 ft was about 218 (average for 3 leg triangle course). Mine has a bit different twist and tip shape I think...pretty aggressive.
I run 160 HP IO-320, carbon fiber engine cooling plenum with Sam James style custom cowling(reduced frontal area). It is pretty light, and all faired in and flushed, racing wheel pants. It qualified at Reno Air Races in 2001 and held some speed records early in life when it had an O-360 (200hp angle valve) with CS prop. She is a pretty fast machine.
Pictures if interested. I would have to look at the data sticker to confirm the pitch.
Cheers
