Yes, that would be an option… balance the platform in the center and use only two motors to simulate pitch and roll.

Remember that it would then be incredibly easy to add another actuator to the system to incorporate heave later on. Or then add another for rear end sway… if you want to feel when your rear wheels are getting away from you then a simple 4DOF system is great.

That way I think since you’re only tilting the seat, the actuators could move faster or have a lower motor cost? I’m interested in a relatively low cost simulator that will exactly mimic pitch and roll of a vehicle in racing sims.
Just googled to try to get a picture of what I mean, and I found an example almost immediately:

Depends if you want heave or not.
