Wookiee ornithopter or Wookie Fluttercraft, you got it Darth.
Once again looking for something different I came up with this idea after seeing a DragonFly ornithopter in action.
"The Wookiee ornithopter is a lightweight twin-seated scout craft armed with a tail-gunner used to defend the tree-cities of Kashyyyk against attack. The nimble aircraft were used during the Clone Wars." From the Star Wars Data bank
It appears in Revenge of the Sith. Throw the movie in, click on chapter 17 or 30 and check it out. It pops up a few other places too. Anyway below are a few shots from the movie and a couple of the model so far. I'm tring to keep it light and simple.
