The name Kite, doesn't really inspire confidence. I mean, it's related because it flys in the air and all, but kites don't react that well without the string.
Opens up a whole range of names though. Leaf, windmill, pinwheel, cloud, smoke (hmmm, smoke is kind of cool), balloon, yadda, yadda, yadda.
There's the kite bird I suppose, that is pretty cool, if lightweight, but that is not what first comes to mind for me.
