If anyone remembers the '98 WB Con, there was a guy that had a motion simpit (mocked up at a Hellcat) and that is what exactly he did to simulate G forces. It is also worthy to note that the main guts of the motion pit was a CH Force FX joystick that controlled the motion and would work with any game that had force feedback support. Forgot the guy's name, was from Alaska and one of the CH distributors up there, think it was Lord Frog or something like that.
ack-ack
That is a good friend of mine, Phil - was an old AF colonel who drove A26's. Was Accu Flight group. Was at my wedding actually. Worked on those simpits when they were temporarily at the Niagra air museum getting AH 2 setup on them. This was in, odd 2003 - had a 109, 51, Hellcat and something else.
