Oh yes it gets to the Mun just fine, with plenty of fuel to spare (not even using any lander fuel either). Heck, I bet if there was another planet it could easily make it there. If I remove the super heavy lander from the top and just use stock parts to make a lander, it reaches the Mun far too easy. I figured out that I can zoom out by using +/- on the numpad, so now to make something even larger, because 18 LFEs just isn\'t enough.
