This realy helps, its giving me a lot of ideas.

I'll try to use that when I get back to it,(got side-tracked)

For my steering:
I took the link wheel off of the servo and put a gear on in its place,
I used this gear http://guide.lugnet.com/partsref/search.cgi?q=3648
with a screw threw the center conecting the way the control wheel did.
this gear runs the steering mechinism.
For the drive motor I just mounted theservo to the top of a batery box so
that a cross bar on the servo pushes the buttons.
