Here's a site of someone trying to create a sim motion base:

Note that commercial bases run about $15,000 - $25,000. (!)

Not to mention that you'll need some math background and have to write
some nice algorithms to fake the motion. It is not just a matter of
tilting with the scenery... that'll just make you feel sick.

In motion sims, you do it another way: for acceleration, tilt back.
For going up, lift everything. For deceleration, tilt forward. For
banking, very likely lift everything also (to give the G-force
feeling).. you don't tilt the base, because that's not what it really
feels like to bank an aircraft.

And finally, you need "wash-out" code, to slowly return the base to
center without the user noticing.

It's pretty complicated stuff, apparently.
