This really is an excellent pack, great work! However, if I may offer some constructive criticism: -Parts are not fuel crossfeed enabled (no reason I can see for them not to be? in my game I modified the module .cfg s to enable fuel crossfeed on all of them). -both the 1m and 2m fuel tanks have a fuel/weight ration of 250 fuel: 1 weight, the stock parts have a ratio of 200:1, because the 2m module is so large, I think it can stay the same, but I think the fuel/weight ratio on the 1m modules should be either 200:1 or 225:1 for balance reasons. Keep up the great work!
