I was thinking more along the lines of...
An 'I' shaped chassis, i.e. long bit down trhe middle with two perpendicular bits on ewither end. A bit like the very simple lego-kit chassis'.
Then attach wheels on either side through blocks of wood, solid axle at the back. Also a solid axle at the front, but on a pivoting thing to provide limited and crude steering.
However, I was thinking about making a sort of Chopper steering thing. Basically a tricycle. But with a chopper style front wheel, i.e. tilting rater than rotating. Not the best way of describing it but if you think of the difference in front suspension on a chopper and a Superbike, say, you will get what I mean.
I also was tryng to think of clever cunning names. Nothing yet.
I also though just now that maybe 12" bike wheels would be better than pram wheels. Stronger, fatter, more grip more stability and looking schveet.
Oh, and maybe a big old Fiat Badge somewhere.
If anyone saw the program and saw "The self preservation society's" car, maybe we should do the same with a scaled down cinq? hehe
