Yeah I get what cool5 is saying, you should make the tires then make the transfer tracks with 3ds or wooden supports to make it even look more realistic. I'm sure this will be a good recreation because it looks you know everything about this ride.
As far as I know, they are not. I'm taking this from the second-to-last airtime spot on the blue side, where you get air entering the hill, float down a little at the top, then get more air on the way down.
