Prop Balance
Has anyone had experience with dynamic prop balance issues on the 337? I had my rear prop overhauled and they removed the dynamic balance weights that were on the spinner backplate. After that I had a vibration at 2300 RPM. Had the prop dynamically balanced which reduced the amplitude of the vibration and increased the RPM range in which it occurred. Prior to the prop overhaul there was no perceptible vibration at any RPM.
