Thanks tothemun, The mods I use for this ship are tweakscale, and FAR (I don't know if FAR changes anything but in the .craft it says FARBasicDragModel on all things). I also have trajectories .25 installed and I'm also not sure if that changes anything. here is my .craft file: https://drive.google.com/file/d/0B3dvXUhuD8puV2xUVTBOZDRpSnM/view?usp=sharing
