I'll definitely have the students abuse the chassis a bit to see if we need to do something about the plastic block for the middle wheel. If it's too fragile, I'll have to mill down a versablock to get the same spacing.

I think the block would be fine if it didn't take so much load from wheels being cantilevered. We had the issue on the outer wheels of a wcd and not so much the middle wheel because at that point the middle wheel was in the air, or didn't hit the defense/obstacle first/last.
