Hello, all. I know I don't post here much 'cause I'm more of a space fan...
but I just wanted to ask you all for some help.
My 8th grade science teacher assigned us a project in which we have to make
and race a model solar car. So, because of my (right) belief that Lego can
do anything, I've made the body out of Lego and modified a Lego gear to the

transmition, right now I just use a 1:1 ratio of 24 tooth gears, and either

two different combinations of gears and wheels)
So, do you guys have any ideas for a light, strong wheel and gear train?
Thanks!

Those wide semi-pnuematic one's have good grip, but they'll suck-up precious watts in (...) (22 years ago, 20-Apr-03, to lugnet.technic)
