The SFX100 does heave exceptionally well, but would need a g-seat set up on top to fill the void in forces. In a turn the load factor runs vertically through the aircraft. So whilst the SFX100 sinks with heave, the g-seat would apply pressure on the legs. Thats about as close we'll get in sims I think. This works even better in VR because when the SFX100 sinks, your view point also sinks in the sim giving the illusion of being pressed into the seat.
