Y'know...I don't see how that could happen.
How on earth would that work with a normal stick? The "other game" model does a decent job of this I think (the stick physically moves, but not much comes out of it).
Even with force FX, it's not possible. At least my FF stick has a cutout...so that we don't break the stick off (they're just plastic afterall). On my Force FX, it's pretty darn wimpy (I'd guess around 10 pounds of pull). Now, if someone out there knew how to make your own FF stick, then maybe we'd be able to build one beefy enough to simulate the stick forces that were present in such aircraft.
Although, honestly, in all the Warbirds I've flown (not many at that, and they have all been trainers, but they weren't slouches...especially that T-28!), the stick forces weren't a problem. For instance, in most of the speed range of the T-28 I really didn't have a problem getting maximum aileron deflection throughout the speed range I tried (not quite to Vne, but close). I'd venture a guess that they wouldn't be excessive in a P-51 either. Of course, I know that I tend to pay little attention to the work I've put into flying, so I may have just been enjoying myself to notice that I was pulling so hard...
