I didn't buy anything spacy since, well, since Futuron actually. The occasional impulse, but nothing bigger. So I had to rely on lots of odd technic parts to get the colour sceme right. That most of my grey and blue stuff is yellowed didn't make things easier. The building was fun nontheless, especially the Hauler's cab. It involves so many "illegal" techniques that I actually broke one of the blue inverted double wedge things in the process of attaching it to the inner frame. Fortunately I had four of those.
