I reckon that with the amount of effort and time you are spending on this one, its worth considering a spend on the lipo's you will be able to save loads of weight and space. I know its more cash, but it seems a shame to waste the opportunity. I hope you are using a lot of bolts on this one . I think it will do well, I've been watching videos of Sewer Snake, the weapon is effective and versatile. if only he would cover his wheels up
