Good to know.
I had briefly considered it for a project of mine.
After some asking around I found that he general consensus is that air assist steering is really not worth the expense or effort for the results you get.
Not that it does not work, but I am told that they can have a sluggish and funny feeling, can use a lot of air.
It is worth the extra effort to use real hydraulic assist power steering, and stay way from the air.
Again, I have no actual experience with air steering, but this is what I learned when I was researching it for possible use on one of my projects.
