[request] Newton?????? tutorial

[Goku1910]

I'm requesting a very specific tutorial....An immelmann where the inversion ends almost parallel to where it entered....for example rides like X-Flight or Banshee. (pretzel loops)

I can not seem to get the shape right when it comes to this...

I'd love to help! But I use newton a lot and I know a lot but it is really hard to explain, Sorry dude!
