XRAY - Model racing cars

Hey gang, I'm planning on getting an RX8 after I move. May be a little bit, so to remind myself of the big picture I want to try to get an automatic RX8 steering wheel to replace the manual steering wheel with once I get the car. Reason being is that I want to have the ability for cruise control, which I assume is a button on the steering wheel. I drive a lot of highway.

That's the idea anyways, realistically I know it depends on whether or not it would work.

So my question to you guys is this: Where/how is the cruise control in the car, would I be able to replace the steering wheel with an OEM wheel w/ CC button on it?

If my plan would in fact work, where should I look at getting one?

I have read your excellent post. This is a great job. I have enjoyed reading your post first time.
