If the clutch weighs as much as an entire drive should weigh, that would be a good reason to stay away. It sounds like they didn't know how to deal with the forces at work, & took a sledge hammer approach at avoiding problems.

What I have found is that if you want there to be a Rotary Engine forum, you hav= e to do it yourself.

If I had a flying Rotary, I would be willing to do this but as I do not, it wo= uld not be appropriate.

=C2=A0

We should make an effort to have a =E2=80=9CFly Rotary=E2=80=9D forum and pres= ent our case for the Rotary Engine as a viable alternative to the piston solution.=

I would propose that this comes from our group rather than as a piggy-back on= to any of the other alternative engine groups.

I would not want for our engine solution to be sandwich between the Corvair, Subaru and Volkswagen groups.
