i absolutley, with a passion, hate the top peice of the flamer. the part that connects on the top of the barrels to the dreadnaughts arm. So, i created a really crappy, animation to show you what i would do. Bare in mind, its crude, took me 5 min haha.
I would replace that peice completley, and put some sort of a tank up there, with cables running into the barrels..
good luck with it, and as far as smoking...you sir, make me sick!
