Open Biplane

This is a biplane I made awhile ago... yeah
technically it is not a biplane, as the bottom set of wings act as flaps, actuated by hydraulics...
since the pictures were taken, someone added huge gun barrels to the wings, which I was too lazy to take off, if you wish them to not be there, then you are going to have to do a bit of editing...
I know the propeller is tiny... but once again I am too lazy to fix it...
(note, you need SketchUp to view the file)
took me forever to make, hope you enjoy!
