I guess what you need to do is figure out where you are, and where you need to be, and decide if you can get there using the kit chassis, or if you need to do something else. Also consider just modifying the kit chassis, making kind of a "hybrid" chassis that uses as many existing parts as possible, but new parts where needed to make it work.

Another thing....we try to make the "upper" part of the robot as light as possible, and we don't worry much about how heavy the chassis is, within reason. Our first year, we had a top heavy robot, and learned the hard way about center of mass.

This year we plan to make another steel chassis, it's pretty entertaining watching people see it and shake their heads in disbelief

What is/was the design flaw? I am very interested to learn what the flaw was and how it impacted your robot.

Welded steel chassis? Approve!

OP: the kit frame is probably more than adequate for what you want. My team will be using a customized kit-frame, welded together to save the weight of the kit fasteners (~3lbs).
