Every Chopper needs to be designed before it can be built. Now I personally feel that simplicity is often best... not with the choppers, of course, but with the design process. Therefore, I like simple programs to help me out. 3D is cool, but nothing compared to Paint. black and white works best due to it's simplicity.

Here are a few design ideas. Some of them have been finished, like Ass-End or Earth. Others are still on the drawing board. I highly recommend simple design like this before constructing a chopper, as I never would have been able to build things like fire without this first.
