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 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

My experience with UAV control systems is that scheduling gains with
airspeed is a good idea if you want control over a wide envelope. It
is difficult enough to make the vehicle stable over the entire flight
envelope. If you want anything approaching optimum control, you need
to have gain
