Now do keep in mind, this tip is for WEIGHT saving. Not for component protection. Basically, I found out that if you externally mount all components larger than a TWM3R (NPC's don't count), you are going to save weight, because you do not need to extend your chassis (Which'll cost you more than the 3kg's of a multi-extender) for the component. Again, this is not for component protection, and with some fancy halfsheet and skirt work, you should be able to protect whatever component you want to protect anyway. Technically, this could also count for Stock, but we all know that robots in stock with all their components externally mounted and with no ramplates or snow plows get chewed up and spat out.
