Mixing scales?

[Espeefan]

No one really builds models to an exact scale. Some things just don't scale down well enough to maintain their accuracey and functionality. Neither Wedico or Tamiya models are dead on accurate 1/16 or 1/14 scale models. 1/12 is still pretty big. Maybe you wouldn't notice a 1/12 scale construction machine being larger then a truck from either scale, but a truck that is 1/12 scale is going to look grossly over sized when it's being loaded by a 1/16 or 1/14 scale machine. Most construction equipment is bigger, in the real world, compared to a truck. If you don't mind the scale differences, I say run with it and have fun!
