    i made it but one wheel is always strongest other one.


    The whells go on the yellow rods then it is driven from the yellow gear.

    I found a way of holding the yellow gear on without the wire but it does require a broken rod.

     I posted something very similar a while ago (here: www.instructables.com/community/Knex-differential/ ).  Instead of using wire I modified (drilled a hole in) the yellow gear.  Your cage requires more pieces, but the additional structure may make it sturdier, I'd have to build one to find out.

    I'm glad you like it! Also see version 1.

    Hey whats the diffrence between them does no. 1 hold more weight?

    I made no.1 first, then a while later made no.2, which i slightly more compact.

    What is the piece of wire for?

    looks cool, i'm going to make it

    looks like some cimplicated part you got there :o
