I've watched videos about it, but I don't see the special thing about it?! I think that's time waste

Try to create a turn in regular no limits that sustains exactly 3.5 gs and has no lateral gs

Why should I wanna do that? It's good enough like this

Youll want to later on.

Watch a newton coaster on u tube and compare it to a non newton coaster.

I did :O. And I didn't saw difference

I can't really find any "Newton" coasters on youtube. It's just building one. Do you render it in No-Limits?

Yes. You build the ride in newton then export it into no limits

Yeah. But what can you do with Newton what you can't do with nolimits?
