I am very close to making a (stock) working one, it has a lot of little flaws and isn\'t the prettiest, but it almost gets the job done. I am trying to get the balance right for upper atmosphere (around 40km) boosting where fuel usage starts to make it unbalanced, with the tradeoff being no more liquid fuel for the rockets left. The shuttle performs fantastically when it comes to landing. Here\'s a pic, I\'ll see if I can take a video or something later.
