engine performance - ZDZ vs 3W: Help me build this database.
I have an RCS180 with the "Pitts" muffler. . out of the box it turned a 18-8 Zinger at 7700-7800 rpm. I switched to a 18-8 Master Airscrew "scimitar" series wood prop and picked some rpm, to 7900-8000 . Have not fully broken the motor in yet.
