Richard,
I was thinking about that was well for the
single, I figured some extra rotating mass wouldn't hurt in smoothing the
torsional vibrations of the single. What thickness did you settle on. I
figured you used the manual diameter ring gear.

Your comments remind me of my initial
experience on the SOOB, about ten years ago. I initially used a flexplate
for a flywheel. After the first 20hrs flying, I found the flexplate cracked
around the flange, where it was riveted to. There was no load going through
the flexplate in my design, all it did was holding the starter ring gear. I
solved the problem with designing and building a much stiffer flywheel,
which is still there.
FWIW
