I am almost entirely an "away" gamer, all of my games happen at other people's homes, at the gaming club on the weekend (we take over a room at the university every Sunday) or at conventions. So transportability is huge, my terrain, figures and vehicles
have to be safely and securely movable or else they're useless to me.
So I sat down this evening with some scrap cardboard, half inch foam, and my glue gun to begin a SPAD caddy.
There's a rectangular hole in the front centre there to hold the landing gear and prop disc; the piece of cardboard across the front is glued in to stiffen the front, and I'll probably run a strip of cardboard around the whole thing, or at least around the two front corners just to protect the wings as well as the prop.
The scraps of foam around the tail actually hold the model in place to keep it from shifting in it's foam bed; it was easier to use the tail as the securing point than elsewhere. I'll probably run more foam down to the back corners just so the caddy is roughly boxlike and other things (like the eventual caddy to carry the Red's Nieuport) could rest on top of it.
