It's an artillery ornithopter or something, flies around then fires it's cannon at something. It has that black fin because I just can't find my fourth white piece... I think I'll call it The Frostbite
The wings are supposed to flap, I can also put a massive bomb under the tail for better anti-ground results.
Hopefully I'll add to this in the coming weeks, I'm starting a new thread because I've revamped plenty of stuff, got a new photograph setup and I'm bored of the old one.
