I have a Simxperience GS5 G seat in my racing pit. In VR it does a very good job of tricking your brain to believe you are pulling g’s ina turn. Unfortunately it doesn’t have a software interface to DCS or any other flight sims. They promise to add flight in the future but it will be a while. If you combined this with motion, it should be effective at giving a good sense of flight particularly in VR.
