as you have seen(or not sean) i am making battle bots. one has a machine gun and the other has a knife(i also have a mod for a drill that does not use the orange gear) they are made that there is just driferent atachements on the bot body. so even with out the body you could make a mod( like a saw) with out the body. that is what this forum is for. people who can not make the body. you can post a mod and i could try it for you and give instructions for you and other people. i will give you full credit for the mod.
