Yes. Unfortunately, the balance masters ring didn’t work for me. To install the balance masters part, I needed to remove the weights I added to my starter ring gear when I did the DynaVibe balance originally. With the weights removed, and the balance masters installed, my balance using the DynaVibe went from .07 IPS to .30 IPS (rough). I confirmed this with flight testing. I could literally see my glareshield top surface vibrating. I removed the balance masters ring and rebalanced using the DynaVibe. When I do this, I need to remove/reinstall my GA prop blades. Pitch is set on the Sensenich using pitch pins. This invites possible small errors in pitch setting. Nothing will affect vibration faster than uneven prop pitch. My balance after removing the balance masters and rebalancing using the DynaVibe was/is .04 IPS. After flying it, it was smoother, but didn’t seem as smooth at it did originally. Maybe I had become hyper-sensitive about this, but I looked into it further. According to Scott M (Vans) related to this subject, a pitch variation between blades of more than .1 degrees will be felt. So I bought the tool from Vans that you use with a digital level to measure prop pitch, I measured the pitch I has set with the pitch, and found them to be off by .3 degrees. I adjusted the blade pitch to achieve a 0 to .1 degree difference. This was difficult, because when I tightened the clamp bolts, the pitch would change very slightly. I called Sensenich and got the guidance on pitch setting and bolt tightening technique. so I got the pitch setting to within .1 degrees blade to blade, and it feels smoother on my finely tuned butt. I haven’t re-checked the balance with our DynaVibe again yet - it‘s been really cold here - but will eventually, and I expect it to be improved, even though .04 is pretty good.
