The foundation of any flight case lies in its walls: the base, lid, or the doors. If you're building your own bespoke case, then the first question you're likely to ask yourself is, "What will the panels be made of?" You could opt for plywood or multi-ply wood veneer, or you could go for something a little more exclusive like polypropylene to keep the weight down and make it more water resistant. If you already have the panels figured out, you can start picking out the other bits from our healthy selection of other flight case parts.
