It's been posted in the past month and the team did answer along with some of the same fine suggestions listed here. It is possible that you could still get S-Turns without applying some of the suggestions. Different things work for different set-ups so there is not a one size fits all solution!

It's hard to miss informative posts when 99% of the posts are whinging about something. So the s turn issues aren't a problem with the NGX?

Hi, You still need to use the work-arounds. If you don't you could still get S-curves.

It's hard to miss informative posts when 99% of the posts are whinging about something. So the s turn issues aren't a problem with the NGX?

From what I understood from previous posts from Jim Skorna and PMDG in older threads, S-turns are not problem specific to the airplane, but to the way that ASE updates the weather in FSX. The 'tweaks' may help to make this issue go away, but it's not 100% guaranteed. PMDG may have done things about it to prevent or reduce ASE effects in NGX's autopilot, but it will still be latent and the S-turns shall return 'randomly'. I for one use only the tweaks provided by HiFi Sim in the manual and never had problems with S-turns ever since.

I have never experienced S-Turns in J41 or MD11 (can't say for 747) so I don't expect them in NGX. The only exception is ASE DWC+FSUIPC with some specific features turned on. If you're experiencing S-Turns try fallowing settings in .ini (with those settings you don't need additional smoothing and you can enable turbulence effect in FSX): SuppressCloudTurbulence=YesUpperWindGusts=NoSuppressWindTurbulence=YesSuppressWindVariance=YesWindTurbulence=NoSuppressAllGusts=Yes Don't worry that you will loss some effects, they still will be there thanks to ASE.

Sorry for the revive but this deserves to be sticked somewhere because I have been fighting with FSUIPC for a week and despite all the "turn turbulence off" advices this one works the BEST. I even ran a test rounder on EGLL-LFPG-EBBR-EHAM-EGLL and I only entered one heavy turbulence area where my plane was going like in this video:

But it didn't get bank angled nor lost VNAV and she was able of recovering without me intervening. You sir, deserve many beers!
