Different shapes of Cobra Rolls

Wednesday, January 16, 2002 12:21 PM
I was looking at the Cobra Roll on De javu @SFGAm and then at Raptors @ Cedar Point.  Besides the fact that they were designed by different people, why are they so differently shaped?

well, the one on deja points you around 45 degrees towards the entrance of the cobra roll, while Raptor's points you just about completely opposite of the entrance, if that makes any sense.  Also, i bet the vekoma looks a lot different because it is very tall, and there is some consideration because it has to go through forwards and backwards, backwards, relatively slowly, too.

...and technically Vekoma calls that element a "Boomerang" while B&M calls in a "Cobra Roll". Arrow calls it a "Batwing".

There's actually a lot of room for variation on a cobra roll without changing the basic look and idea too much. Mess around in No Limits for a while and you'll come up with some great twists on the standard Cobra Roll.

I'd imagine most of the difference comes from which manufacturer did it.

I've even noticed some difference between B&M cobra rolls.  For example, older ones (like Raptor) fling you through the elements very quickly and in rapid succession, while newer ones (like BKF) are much larger and there is much more space (and time) between the two inversions.

Those are a few different angles of the Deja Vu cobra roll...And here are the cobra rolls of Superman: Krypton Coaster, Top Gun: The Jet Coaster, and Raptor.

Yeah, sorry it is Alpengeist, I was looking to see if  Top Gun had a cobra roll but remembered that it had a batwing, so I just got Alpy's. My bad...

I saw a Roller Coaster with a cobra roll, but it was very different. It did the normal inversion but instead of doing a half corkscrew, it kind of did an barrel roll, made a U turn and inverted back down. It was just like a cobra roll on thing is just take the dipping part and raise it up

I definitely prefer the stretched out Cobra Rolls, like those on Hulk or even Kumba.  The tighter ones seem to include a bit of headbanging...

I would assume the difference in shape of the cobra rolls has to do with the speed the train enters the element at. The higher the entering speed, the more "Stretched out" the element.

The cobra roll on Hulk appears to be much further off the ground than the ones that B&M normally puts on their coasters.  It appears that the train climbs quite a bit before it starts to invert.

Jephry, your thinking of the first inversion on SLC's. I think they are called butterfly's. There is also one on Superman at SFH.

While I dont think there is an "official" term for the heart-shaped inversion found on SLCs, S:TR @ SFH, and RnRC @ Disney Studios, I'm pretty sure "rollover" is the 'accepted' term in so-called enthusiasts circles.

Personally, I'm not a big fan of cobra rolls. In fact, the only one I really *like* is the one on Alpengeist. That sucker is intense! But IHC has the best *looking* one

I think the weirdest cobra roll i've seen would have to be BKF. If you go to the photo gallery on coasternet, and look at one of the pics (forget which one), you'll see that the valley between the two inversions kind of "bends" outward, like it's entering a helix. At the end of the bank, it whipes up and inverts the train. Has anyone else noticed this? (besides coaster131, lol)

How much more floorless can they get?

Jeremy, learn your terminology...the first inversion(s) on an SLC are called the "heart attack."

2Hostyl, I didn't know that RnRC had a "rollover"... I always wondered what it would be like to go through one of those in a normal train (opposed to a suspended/inverted one).  I don't understand why more designers don't use a similar type of element on steel coasters.

It actually looks normal in real life. It havs a very huge roll in-between the two flips.  But it doesnt look odd to me.....

"Supposedly", the layout for Superman: The Ride @ SFH is identical to RnRC. Believable, seeing as they are both Vekoma (aka Clone King) products. I've never been on either myself...
