? I don’t know who is saying that, but it is far from the truth, while we don’t have accurate figure, El Toro and Steel Vengeance for certain don’t exceed -1.4g, and even that is a stretch. But -2g is just ridiculous, it isn’t safe as the upward acceleration causes blood to rush towards the head which can cause all kinds of medical problems.

I could have sworn that I heard that El Toro’s Rolling Thunder hill pulled -2.2G or something crazy like that? Skyrush also allegedly pulls -2G in places, and apparently DC Rivals’ non-inverted loop was once measured at -2G during testing, so it can be pulled off on coasters.

I've heard -1.8g for Skyrush and a similar number for El Toro's HILL (it deserves emphasis). Keep in mind that Skyrush only sustains those forces for probably three seconds at the absolute max, although it's likely that the rides only sustain a negative G force and instantaneously hit that peak. It's incredibly intense, but it obviously won't kill people.

Maybe it's just me, but I'd definitely say it's just a reflection.
I did a test run with my professional accelerometer on Untamed, which's airtime is somewhat comparable to SV (at least a friend told me who did both). Untamed barely hit -1,0g in the end, it will be a little bit more with a full train. I doubt that it will hit more than -1,4g.
One thing which makes Airtime feel more intense is the transition from positive to negative forces. If they are very quick, the Airtime will feel much stronger initially.
I hope I'll be able to measure Zadra soon, but it's hard to make any promises due to COVID.

El Toro is definitely less, obviously it isn't professional, but the most I've seen for it is -1.4g on the rolling thunder hill, and honestly it doesn't feel like it comes close to Skyrush. But the only rides that seem to pull even close to -2g are Skyrush and the Raptrs, though there were some rumours circulating about Camiel Bilsen saying something about Pantheon hitting figures approaching -2g in the back.
Also that is definitely a trim from this closer angle, but there should not be concern since Intamin have released figures for the hills, so it is just to moderate the speed, like on DC Rivals. I personally am more concerned about the trims on Velocicoaster and other trims of that nature where it is on a top hat, as that can impede the airtime on the elements.

Tell that to the one on I305's first drop!
and yes I know the reason for that trim is different so don't @ me

The trims on I305's drop got removed when the first turn got re-profiled anyway.
Yeah I agree shame about the trims, just hope they don't impact the outer-bank too much. I mean Skyrush has three trims that no-one seems to notice.
I have a cloudy memory of seeing B&M Hyper track with the 'old style' trim mounts (circular holes in the track for the pneumatic cylinders) installed but not in use too. Can't recall which one, though.
There are standards set by the American Society for Testing and Materials that specify the limits roller coaster manufactures should adhere to when designing a roller coaster.
For negative vertical g-forces these limits are the following (Base Case is a regular restraint, "Prone Restraint" means the restraints found on flying roller-coasters):
And for positive vertical g-forces the limits are the following:
All the graphs are from the Brain Injury Association of America, which I found on an excellent post on Nolimitscentral, which dives even deeper in the different type of g-force limits on roller-coasters.

I've never ridden Skyrush, Maverick or El Toro, however I doubt, that (with such standards and limits in place) these rides pull such enormous negative g-forces.

Superman at Georgia has places for trims to go if needed, but were never filled. (Used to be joked as Vipers Snake Bites)

Like Hixee, I remember seeing the same on more than one B&M - I just can't recall which ones off the top of my head. Millennium Force also has trim brake mounts that ultimately weren't used. I'm sure we can find examples from every manufacturer but most aren't quite as obvious as these examples.

Now this is a nice view:
Given all the problems the park have had with locals in the past, it's good to see they've been able to reach some sort of balance for the park to be able to build a bigger ride!

Walibi Mega Coaster Construction Update - August 18th 2020 - Coaster Kings
Honestly, I’ve never been more excited for a new coaster in Belgium. This new Intamin Mega Coaster looks so cool and you’ll want to read this update. After the completion of the lift hill and the Non-Inverting Cobra Roll, a new element has been finished! – In the past, many of our images have...

Just thought I'd point out there are only brackets for trims installed on the airtime hill, there aren't actually any brake fins installed as of yet. Let's hope it doesn't end up needing any.

This guy right here. I have a feeling that we will eventually see a trim show up, but there is the possibility the mounting points were placed there as a just in case.
