Roller coaster types that never really took off

Hi guys. In this thread, I'm discussing what coaster types never really took off. When I thought of this, four ride types sprung to mind. These are:

• Intamin Prefabricated Wooden Rollercoaster - Since the ride type's premiere in 2001, only four of these have been built, with the most recent opening 10 years ago in 2008. I'm not even sure whether Intamin still sells these.
• Vekoma Invertigo - Since the ride type's premiere in 1997, only four have been built, with the most recent one to open, excluding relocations, being 19 years ago in 1999. As the newest Invertigo is turning 20 in 2019, I don't see any more of these being sold. If Vekoma still sells them, that is.
• Vekoma Giant Inverted Boomerang - Since the ride type's premiere in 2001, six have been built, with the most recent one to open, excluding relocations, being 4 years ago in 2014. From what I've read online, these are generally quite good rides, but they have generally been a reliability nightmare for parks that have built them, so I don't know if we're going to see any more get built.

Now, the fourth one is a bit of a controversial one, but I'm going to suggest:

• Drop Track Coasters in general - Now, it may be a tad unfair for me to judge this type as it is still relatively new, but hear me out. Since the ride type's premiere in 2010, five have been built excluding the Chinese contraption manufactured by an unknown company, with the most recent of these to open, again excluding the Chinese thing, being 4 years ago in 2014. While there is still time for more of these to be built, I don't think many have really been sold in the 8 years the ride type has existed for, and I don't see any sudden surge in drop track coasters coming any time soon.

So, these are the coaster types that I feel never really took off. Do you guys disagree with me?
P.S. Sorry if there's already a similar topic. If so, feel free to lock this thread.

 

Intamin's Reverse Freefall coaster is a good example; only 2 were ever built, both opening in the same year which means nobody who ever bought one got to ride one first!

 

I never actually thought of Intamin Reverse Freefalls, but it makes a lot of sense now you say it!

 

Intamin Wingrider. Shame really, if they could just nail the train design to enhance guest comfort then I reckon the concept could sell quite well. It'd be interesting to see what a more sophisticated launched wingrider layout might look like, although I do enjoy Baco's simplicity.

 

The S&S Free Fly aka Tranan comes to mind as a coaster concept that never took off. Only 1 sold.

 

Tilt coasters and pipeline coasters are the first to come into my head.

Also, the world does not need any more Invertigos/GIBs or boomerang type coasters in general!

 

A few more come to mind...

Launched B&M Anything: Now this is kind of new, since B&M has only been doing their own launches since 2015, but considering how many jobs they usually get a year, it's probably fair to say that something about this just didn't draw parks in. Thunderbird is an incredible coaster, most enthusiasts will agree, but it's the only one they've ever built. I'd probably blame the fact that B&M was so late to the launch party and there were just other manufacturers that could provide a similar product that have more experience.

Intamin Winged Outer Seats: Coming from the opposite end of the spectrum, Intamin doesn't get nearly as much business as they used to, so this might not be the best comparison, but considering how nobody in the US has seen Skyrush and been like "we want that!" I think it's safe to say this didn't catch on. Now another one was built, but it doesn't seem to have sold many other parks on the ride system.

Swinging Coaster: When I say this, I don't mean like an Arrow suspended, as those did fairly well. I'm talking about coasters in which seats are suspended on a pin around where the heartline is to careen around corners, such as Seven Dwarves Mine Train. If I'm correct, three were ever attempted, and with Orphan Rocker unsuccessful, the only two to actually open were Seven Dwarves and that Drifting Coaster traveling ride from German fairs that makes its rounds on social media every month or so. Considering how both the similar bobsled and suspended models did fairly well from multiple manufacturers, it seems odd that this one never really took off.

 

But isn't the floorless coaster just an upgrade of the sit down model, rather than an all new coaster type ? They basically do the exact same stuff, with slightly different trains. Therefore, it is kind of logical that most buyers went with the new and improved model after it was introduced at the turn of the millennium. I don't see it as a model that didn't took off, just a model that was upgraded shortly after its introduction.
