speaking of...

I've got a question about stability for you experts.
(I don't mean to hijack the thread but hope that the original poster might find the answers equally interesting, instructive and related.)

How did they handle stability issues with "swing-wing" (variable geometry) designs? I've read somewhere that some of the original proof-of-concept planes were moving the wing root forward as well as pivoting the wing. Then came along F111 with a single pivot and no problems. No FBW or anything fancy to help with anticipated stability issues.

Is there some kind of an aerodynamic trick? Or am I paranoid about CG and center of lift? But wouldn't fully swept configuration be almost impossible to pitch? Was there variable pitch assist?

If someone could spare some time and shed some light onto this matter, I'd be grateful. Thanks in advance.
