[ODE] Trimesh problems

I can tell you right now that this is a problem. The dynamic range of a 
float is only about 1e5, and the difference between your object sizes 
here is on the order of 1e3, leaving only a dynamic range of 1e2 for the 
math. (This is a back-of-the-envelope analysis; real details may apply :-)

With an object size 10, try to make the triangles no larger than size 100.
