Since you are able to spin at all, I assume you have the X vs. O thing figured out, but then the down side comes into play, the correct orientation of the Mecanum wheels means that you are going to be scrubbing wheels (i.e. moving them in the direction of the axles rather than rolling them) when you spin in place. If your little wheels are grippy then they are not going to like that much.

The question is how much are you jumping? If you are just seeing "normal" 4WD with wheels in the corners jumping then there isn't much to talk about. If it is something more serious then perhaps there are things to do to improve things.

Can you provide more details? How about a movie of the behavior?
