I am happy to report I have my RV3A flying now after repairing the broken motor mount and gear legs. It has a fresh IO-320(160 hp) and a 70CM Sensinich prop with 79 pitch. It's a Vans prop, but they recommend the 81 pitch for the -3.
She flys great, and climbs like heck, but this prop is limited to 2,600 rpm, my engine redlines at 2,700, and I only get about 185 mph out of it with throttle left to give and 1,000 rpm below engine max rpm.
I'm wondering if its worth spending the several hundred bucks to re-pitch my current prop to 81 or 82, or does someone have a recommendation for a new prop that will get me all the performance out of my engine? I would love to have a CS in it, but current engine and my tapped out bank account won't allow it.
Thanks
Dave
