if Tamiya wanted to put weight into the models i wonder why use a metal chassis when they can use small metal blocks in the boot and the engine(if its curbside) as they do with model locos, with older locos where the motor is at one end encased in plastic and has a metal block in the middle for weight, nowadays motor in centered encased in 2 metal blocks.

that would have been a better idea and makes the underside more realistic.
