My new-to-me RV3 came with a 68/67 wooden propeller installed on an 0-290-D2 engine. I’m very new to piston/propeller aircraft so haven’t given it much thought until I recently read Tony Bingelis’ book on engines. He suggests that static RPM should be 80-85% of maximum engine RPM. On my engine that should be ~2200RPM. With the current prop, I can only achieve 2000RPM static. The airplane performs well; gets airborne very quickly, cruises at 130KTAS @ 2200RPM.
Sooo, the question is, is this prop appropriate for this aircraft/engine combination? Will a different prop give better performance? What are you folks running on your 3s?
Thanks for any advice and/or suggestions.
