Need help in deciding the configuration for an off season chassis prototype

[cadandcookies]

Square chassis have a major advantage with the advent of the "perimeter" rule, as they maximize volume. With a WCD/generic 6wd they also let you avoid a drop center (if you space things correctly).

That being said, go with whatever the students are motivated to do. Don't lose valuable time and energy debating the chassis dimensions when the point is giving the team practice.

Speaking of the point, when your team is making the decision, make sure to take into account the intended purposes-- to practice machining? To prove that you can do it? To have an excuse to hang out in the shop over the summer? The core purpose of this project should guide it from beginning to end.
