Er... see what Ryan put. The coaster was only a quick, one hour job, and was just to show what it would look like- no effort was put into it at all.
And the lateral G's were not too high at all, it only peaked around 1- maybe a little too high, but smoothing would improve it.
Also, it's a bit strange to say they're too high, and then change the banking, layout etc. which puts the G's into red figures on multiple occasions. A bit hypocritical to suggest that 1 is too high, but over 3 isn't.
The coaster itself has been made much too intense, even when it's fine for G's. It is meant to be a family coaster.
Onto the actual project. I am going to decide to use a Intamin inverted coaster, as this is what is currently leading in the poll. I will try to figure out, with Al, a way to design and make this coaster so it works- hopefully within a weeks time. Unfortunately, next weekend, I will be away for 10 days or so. Therefore, I will try and sort this out before that, so we can get underway. You will be informed soon.
