Are you calculating the K-factor here?  I thought that the radius
to use was the one associated with an equivalent point mass having
the same moment.  This radius would be considerably less than the
turning radius.  Can someone clarify this?

In any event, I agree with the unsuitability of the T2X.  When
selecting a rotor, ask yourself:  "how much trouble is it going
to be to rep;ace it?".
