For the last three years, we've primarily used aluminium for structural parts; in 2005 we used a slab of plywood to reinforce the kit frame and for mounting electronics, in 2006 electronics were on acrylic (never again...) with aluminum chassis reinforcements. Last year we kinda hybridized the two methods, some of the electronics were on polycarbonate and some were on a small piece of plywood; again, the plywood serve a structural stiffening purpose in addition to its mounting job, but this time we also had (smaller) aluminum reinforcements. In '03 and '04 the chassis were entirely plywood, and in 2002 and 2001 they were 80/20 aluminum extrusion. The all out plywood method works, but it can be a bit heavy, the same goes for the 80/20 frame.
