Are the long churros needed between the inner plates?

Hello! We are building the chassis for the everybot and we would like to know whether the 15.25 inch churros are necessary between the inside plates. We assumed since they aren’t in the CAD file or the build images, we’ve assumed that the crossbar has replaced them they are no longer needed, but would like to know for sure.

You are correct.

Only you can tell how rigid your robot is. We generally leave them off, if we attach something else to the middle of the chassis, or if they are in the way of something else, or we just forget to install them.
