The StratoTerra Sparrow is a small airship that probably has a short range, especially considering there isn't a core or propellers or anything. I'm working on adding them, but the tiny size of this thing makes it hard. Also design, it's hard to make something cool looking with only 379 blocks furnished. The up side is, it works very well with the zeppelin mod, and is equipped with a bed, chests, and furnaces.
