Prop Balance

I dynamically balanced my MTs after OH in 2021 — got them down to .03 and .05 IPS at 2400 RPM in a couple runs. Any IPS below .05 is considered “Excellent” according to this AOPA article. What did your logbook entry show?

When first measured it was .35 ips. The lowest reading obtained was .11 ips and that is where we are now. Better, but not good enough.
And thanks for the link to the prop balancing article. Very informative.

You could check with your shop and see if the prop can be mounted 180 degrees from where it’s at now. That will sometimes bring it back in tolerance

Thanks, I will check on that.
