This is a biplane I made. It took me about 6 hrs.. The man reason it took so long is because i hooked up gears to the wheels and propeler so that when pushed the propeler moves. I am not the best at gears so it took me some time to make it work. In the end it came out perfect. It has 2 guns up front, a swivel back wheel, a custom seat, and a working propeler. it is 13 inches long and has a 11 inch wing span.
