An interesting read and I have to admit the vertical supports do match those of an X-Car.
However they also match those on the Euro-fighter
and most of the other supports are not types that are usually seen on an X-Car. This is something I only noticed recently. Having checked the X-Car model there seem to be very few "Lose Ends". If you're wondering what I mean by that here is an example:
Hollywood Rip, Ride, Rockit, A typical X-Car support.
The Supports on Rage: Notice that the section at the top is another section of the support placed on top, creating a lose end. While some X-Cars do have these supports there more common in Euro-fighters and SW7 has them all over the place
The X-Car has another property I am yet to find on the plans. In areas where the cart is under a lot of force the X-Car track becomes more of an oval to take the load.
I can't spot anything like this for SW7. It could be that they don't include such details on the plans but given what they do show it seems odd that such aspects wouldn't be included.
Personally I believe ether one of us could be right but as the plans say Gerstlauer that's who I'm sticking with. It is not out of the question that they have decided to change their track design. As I pointed out a while back they have changed many aspects of the Euro-fighter already.
