The cars need a redesign of the underframe and truck mounting instead of trying to kludge a poor solution. Doug
I'm surprised no one has brought this issue up before as the cars have been available for awhile. Or maybe that's why they still have stock on some of these as people have pickup on the problems. I also did notice that the assembly job on these is not great as I can see lots of areas that way to much glue was used and is quite visible.
