Today I re-installed my newly overhauled 210cm MT prop.
At the request of my IA, I warmed up the engine, then tried mid-range rpm prop pitch changes. All seemed fine, no leaks.
Then he asked for full power: only made 2300rpm
I had never tried this before. The plane made 2700 during the takeoff and climb-out, pre overhaul, but I never tested max static rpm. I told my IA that I could go take off and check RPM. He said even if it makes 2700rpm during the roll & climb, if it’s only 2300 static, then the low pitch stops need adjustment.
Thoughts? We will check tach calibration with a laser strobe.
