They are in 2 pieces. Top and bottom. Yesterday I ordered 4 of the F-Toys kits. That will give me 8, 1/144 scale snow speeders. I did some measurements and find that they will look right with the rest of the stuff. The speeders that come with the kit are decent, but since I don't plan on building another Battle of the Hoth, I thought I'd go for it. The F-Toys kits are a bit higher detailed too. Well, here's a link.
