On mine, the Shuttle was erratic and overly turbulent as well. Plus at one point it flat out just vanished only to fade back in a few seconds later.
As a side note, wouldn't it be better to make the exterior model a runabout to match the interior model? Other wise it just looks a bit ridiculous that theType II shuttle craft exterior could probably fit on it's interior since its much larger.
Personally i'd LOVE to get the Type II interior. It's SUPPOSED to feel cramped and tiny.
Even better would be that it let you select which shuttle to take. I think picking up a Vulcan Diplomat would require something fancier like the Captains Yacht, which i'd love to see an interior too. Dune Buggy and all. I remember being excited when they mantioned we would be getting shuttle interiors and then they hand us the interior for the wrong shuttle.
