This unit is mainly for the Dune mod that's currently under construction, but I'm sure people can give it plenty of use elsewhere. For those finding themselves perplexed by the name, an Ornithopter is a plane that flies like a bird by flapping it's wings, just look at the animated preview attached to get the idea. Anyways, I just realized that this is my first unit that isn't a boat/ship! Even the Highwind was still an airship. Here's the file: Ornithopter Previews below.
