Bug/Crash report here. Image: http://i.imgur.com/55Zhc7x.jpg Log: http://s000.tinyupload.com/index.php?file_id=63537421523359981502 Mods installed are FAR, Kethane, B9, and Part Catalog (but its pretty obvious that its from to FAR). Long and short of it is that the static AoA sweeper-thing crashes KSP if you set the view range upper bound to 90 when analyzing a craft that has the center of lift much farther behind the center of mass (or so it appears). Easiest way to recreate would be just stick some wings on the back of two orange tanks in the SPH. The lines in the analyzer also split and do some crazy things before 90 (reminds me of the sort of splitting/chaos you see in nonlinear diff. equations, which makes sense in hindsight, given the whole aerodynamics thing).
