27 kgs is unnecessary heavy...the 4200 is around 20 kg, and seams like a ok weight. surpriced that they have added additional 7 kg's on top of that..Just makes it more 'stressfull' to carry around and to transport on a low loader. I guess the THS 480 Volvo in 1:14.5 is around 15 kgs, which is a correct weight of a 50 ton machine in this scale. But naturally, it don't hurt with some additional dead weight.
Ah..I'm not surprized with the small C45 steel tracks lie...I did not had much thrust about that info given in the product spec.
