What RPM range should I get from my O.S. 46 fx? I just changed props from an 11x7 to a 12x4 and thought I'd run a ground tune on it. Went to max lean at full throttle and gave it 4 clicks rich. The pinch test on the fuel line seemed to work well ( slight increase in RPM then settled back ). Throttled down to idle and counted to 10. Advanced to full throttle and the transition was smooth. Back to idle and counted to 30. Back up to full throttle with only a little hesitation. Full throttle RPM was a consistent 11,200 RPM. Idle RPM would be around 3200 after 10 seconds and about 2800 after 30 seconds. Does that sound about what I should expect her at 7000 ft. altitude.
