I have Logo 10 3D, Jazz 55, 9C, Hacker C50 13L on 4S4P. I had run all summer at 84% throttle curve (flat line) to get 1800 RPM's. After a rebuild due to crash, I now have to run 70% to get 1800. All I rebuilt was the head. All electronics remained unaltered. I did spool it up without the blades to check for vibration, but had done that before. Anyone have an idea as to what may have caused this change? Thanks, Joe....
