The polcarbonate won't snap, but it can crack. Part of the reason for the redesign was to distribute the load along the chassis a bit better because there were stress cracks forming around the tapped holes in the vertical plates on the old chassis. This new chassis offers more flexibility where it counts, but is still quite rigid.

Think of how much your lexan bodies can take without permanent deformation.

pretty good work
Any details on how you got the front diff drive to work in there ?

I love Polycarb but you may want to consider Delrin, easy to cut, heat bend, light weight. I like it better than aluminum in many cases.

What kind of suspension does it get ?

Cool creation :yes:
