Sorry, I know that this is kind of an old thread. I did a Google search for this question, and this came back as one of the hits. I liked the conversation (I’ve been an enthusiast for years, haven’t posted in years, and never knew of this site before). I was interested in this topic because of how technologically advanced the rides are getting, they’re still stuck in the past in many ways.
So far, the go-to answer for many people on this board has been “Oh, there’s too many G-forces, you couldn’t go through elements at that speed.” I think that’s the 1990’s answer, and possibly the failure of the Steel Phantom has reinforced this fallacy, and scared off designers and parks.
Remember, inversions do not need to be placed in fast parts of the rides, nor do they need to be experienced at breakneck speeds.
1. You can design a ride that uses the terrain, where the fast part is really just a dip that has nothing to with the ride (the SP was really just a basic looping coaster that dipped into a ravine briefly).
2. You can put an inversion after a mid course break run that you were planning for anyway for 3+ train operation.
3. You can put the inversion at the end of the ride when friction has slowed it down enough (this may have been a problem decades ago, but with technology, you can use trim breaks and LIM spikes to make sure that its going through the inversions at the planned speed).
4. Remember physics class, the coaster is going faster, so if you just make the elements bigger, it will feel the same as if it was a slower train going through tighter elements. Granted, they might be worried about a 320 foot drop not being able to power a 260 foot loop reliably, but they could use trims and LIMs and computers to put the trains where they wanted. These guys want to grad school right?
I guess that the next answer where people would gnash their teeth would be putting OTSR’s on Giga coasters. A valid concern. You sacrifice your first born before you put OTSR’s on Gigas. My response to that is since when do looping coasters need OTSR’s? Airtime hills are technically more dangerous maneuvers than loops that actually push you further into your seat. And really, even if the ride stops in the middle of an inversion, it doesn’t matter. Unless it’s a complete joke of a coaster, you design restraints so that a rider couldn’t get of them if they wanted to. You’re about as likely to escape from an Intamin clam bar than you are from a topspin OTSR when you really think about it.
My thoughts on this (taken from my thoughts before this, and summarizing what people are saying):
1. Space restrictions. Designing the elements that are big enough for this to happen, and/or creating “two rides” requires a very long track. And considering that you’re going through this at 90 MPH, getting a decent ride in really adds up trackwise. Something that I’ve noticed as I’ve researched real estate and zoning matters is that most parks are pretty short on space, especially the big ticket ones that push boundaries. They tend to be built near big population centers where space is scarce and expensive, and have to adhere to buffer zones, height restrictions, etc. And the Disney Parks that have the most space reject extreme rides, and go for the family garbage ones.
2. What’s the point? As people are saying, not everybody is a junkie that will ride anything, anywhere, at any time. Most people are “basic.” Basic in life, and basic in coastering needs. Why innovate and put that much time and money into a ride that people won’t appreciate, and that will turn many people off. Some people won’t ride loopes, some won’t ride fast coasters, some don’t like heights. So you’re talking about a big ticket item that many won’t ride.
3. Specialization of design. Let’s face it, parks are vain. People are vain. Why do all that R&D, pay for two coasters, and repair two coasters and only get one coaster. Give people a looper and a giga. And like I said in #2, that way you have something for more people to enjoy.
4. There aren’t that many gigas. Granted, I think its odd that we don’t even see loopers getting to 200, but if you want looping gigas, let’s at least get more chain driven gigas out there to pioneer the type. I think at this point, parks are more into those specialized loopers and 4-D designs or RMCing their old wooden coasters to be too concerned with Gigas.
5. It would have to be extremely well designed, well maintained, and well timed. We have the tech for it now, but I wouldn’t leave it up to old guard who basically used programs about as advanced as RCT. RMC is really giving me hope for the future, but when you’re talking about 95 MPH, and going through serious elements, the devil is in the detail and the quality.
Personally, I agree that there’s not a huge need outside of vanity (“The world’s tallest looping coaster” come check out "Wonder Women: the Jinx of Doom” only at Six Flags! $8 off with a can of Pepsi). But I wouldn’t mind seeing some loopers getting to 220 feet, and hitting 75-80 MPH. I also think that with how pointless the hydraulically launched coasters are, some inversions might legitimize them (you may laugh, but why can’t Kingda Ka invert the top hat? It already has OTSR’s.).
