HEY! That first one that you have linked, I actually built that, although at the time, before I knew about pepakura and stuff, I used just regular printer paper and I had a hard time gluing some of the stuff to it. XD I also shoved plastic shopping bags inside to help keep it from getting smashed to easily from handling it! lol But now that I know about pepping and to use cardstock, I have thought about making it again.

I want to have it hanging in my Halo figure display cabinet.
But I downloaded the banshee and ghost. If I can figure out how to scale them for my figures, I will make it so my figures can get the hook up with a new ride! lol As for the mongoose, I have one of the new figures that included the mongoose so I will just stick to that.
