Ah - the Grumman X-29 FSW - that could be fun to do:) I see the pdf you link to also includes the XB-70A :) <homer>mmmm XB70</homer> IIRC, you were working on the STS program at one point - have you moved over to the Orion project now? Will your JSBSim rocket FDM find it's way into FG at some point? Once you've started thinking about this control system stuff, especially with respect to aerobatic control, I think it's inevitable that missile control systems crop up (probably the simplest aerobatic model because of the axial symmetry) so I'd like to have a play with it. I haven't reached the point where I need a gui yet but I have found that I need to draw out some schematics to help me keep track of stuff as things get more complex.
