adding text inside a bezier circle

I’m trying to have some text follow the inside curve of a Bezier circle, but when I put the text on the curve, it’s facing away from the center of the circle. How do I get the text to face the center?


Rotate the text 180 on the Z axis.

Select all curve points and Ctrl-T to tilt .
Select Curve points in edit mode, click Switch Direction on the tool shelf.
One should do ;).

None of those are working.

What I’m trying to do is put in the text on the main saucer of the U.S.S. Enterprise.
Same orientation, like in image. Grab x to position text.
