How did I make this crazy contraption?!

It was not easy. Well, yes it was. :-) But after playing with it a bit, Blastcharge's wheel section became too-loose to hold the arms up properly. And that stupid Mirage foot keeps collapsing! I'm going to put some epoxy on the joints to tighten them. :-) Anyways, since you asked, here's a few explanation pics: Apologies all-around. I only have a crummy flatbed scanner. And a poloroid.

Per someone else's sugestion, I will be attaching a Thrust cycle to the back/top of this fellow, so that every vechicon will have been incorporated. Plus that will give me a head without having to borrow one from a G1 combiner. :-)
