What if they took the jetlapplate and made the jetpack run exclusively on fuel? And make 2 lappacks be used in the creation, while it would only have 1.5x the charge of normal nano. Then the jetpack would be fixed, because it'd be a fuel one, and the lappack would be fixed. Though it would be cool, in a full nano suit, if all the armor was one unit and energy could be transferred, such as if you took a big fall, your boots have no charge, so your legs, chestplate, and helmet "helped it out" by averaging it's charge with theirs.
