Jay, I need some info on your 5820 design series. I have always avoided using the ST-8 tube cause I could not figure out how to get the ST-7 motor mount tube to center in it. I see the 5820 design series is using centering rings. Please educate me to these centering rings and I will add one more wonderful part to my database.

I can help out here, James. I've done this in "the wild" a few times. It's not a true centering ring, but a couple or so wrap thicknesses of label stock. The fit is either very tight, or a little loose depending on the thickness of the paper and how many layers of wrap you use. YMMV on the number of layers, in other words.
It still shows up in RockSim as a centering ring, however... |
