If the bearing precision is sufficient to constrain precession, it is also sufficient to constrain any instability introduced by the COM being above the bearing point.This renders the rest of your argument moot.

The word is sufficient and it is never sufficient, especially six months after owning it!!

If you had read and understood my argument, that is exactly what I said. On the other hand, inverted bearings are both statically and dynamically stable whereas non-inverted bearings are neither.
Better luck next time, Mark.

yes, we just studied this in physics this week, precession would be more likely when the bearing is way below the COM, rather than closer to the COM...
Don't use that crap with me, John.

Hi Mark...I really do hope that your line of work has absolutely nothing to do with "engineering" anything!?!?

-Mark, he makes -or did, make the Motor Controllers for Win's Saskia TT.
He may know more than you think-no?
Just suggesting ,
