Aha! Look what I just found!

[Metallover]

I was digging through a bunch of crap to find something that would work as a battery tray and I found some old knex models I used to build all the time. I was probably around 12 when I was making these things.

The car has a v... no W16 engine. When you push it the "pistons" go up and down. It's one big hunk of plastic and I remember pushing it down the stairs then fixing it when it broke...

The other one's a tank...







All in all it's pretty schweet.
