[ODE] problems with amotor

"or by 
crossing two such axes; one from each body (for two
bodies)."

do you have any sample code you could show to
demonstrate how you're doing this?

also, i thought only the dot product provided the
angle between two vectors and the cross product
creates a vector perpendicular to the two vectors
(each axis of the two bodies being compared)?

thanks,
