Catto 3 Bladed Prop

Well, isn't that just the coolest looking thing next to a $7000 CS prop? I had a chance to try this baby out on Don Wentz's O360 powered RV-6. Climb performace was exceptional, and cruse was good too although flat out we were turning about 2850 RPM at 211 mph. There is a huge difference in the amount of noise between the Catto and a standard 2 blade wood prop. I was amazed at the difference on the ground during run up from both inside and outside the cockpit. Don commented while we were out flying around with the Catto that the engine "sounded funny". We decided it was because of the lack of prop noise! Impressive.
