Say, in HO scale, 87.1:1, we physically scale-down the prototype
dimensions by that ratio. What if the car were built of the exact same
materials as the prototype, would the weight scale-down by 87.1 also?
No, it would scale by the volume, which goes as the cube root of the scale. That would make it roughly 1.5 to 2 ounces.
