JonnyRCT3 Posted May 20, 2014 Share Posted May 20, 2014 Instead of a flat turn, I think it should have been a turnaround like Millennium Force overhead turn after the drop. I think the park wanted to go for something a bit more original. The ride is inspired from Mega-Lites & Maverick, so the high speed turn only makes sense. Although their calculations were a bit off.

rcjp Posted May 20, 2014 Share Posted May 20, 2014 ^Were they? I mean, if you have the speed of the train and the radius of the turn (which they obviously did) it's pretty easy to calculate the G forces. Probably they just weren't expecting the wheels to suffer so much wear. That's only a guess, though. Link to comment Share on other sites More sharing options...
JonnyRCT3 Posted May 20, 2014 Share Posted May 20, 2014 ^Something was off, or else there wouldn't have been a re-profile. Link to comment Share on other sites More sharing options...
rcjp Posted May 20, 2014 Share Posted May 20, 2014 ^Of course. I'm just not sure it was the actual Gs the turn produces but more the effect it had on the ride. Link to comment Share on other sites More sharing options...
JonnyRCT3 Posted May 20, 2014 Share Posted May 20, 2014 However you look at it, the track was re-designed to lessen the G forces, we at least know that much. I've always found the increased radius to be a bit of a stretch. Due to how the new track utilizes the same footprint as the original. Link to comment Share on other sites More sharing options...
rcjp Posted May 20, 2014 Share Posted May 20, 2014 ^Yeah you're definitely right about the increased radius. I guess people used those words because it would have had a similar effect. Link to comment Share on other sites More sharing options...
Belgiumcoasterfreak Posted May 20, 2014 Share Posted May 20, 2014 In the time that the European division of Six Flags still existed, Stuntfall, The GIB from Parque Warner Madrid, was normally planned to be build in the formally Six Flags Belgium (now Walibi Belgium). The rides location was on the spot next to the waterpark, Aqualibi (nowadays you can find Cobra over there). But, the neighbours refused the original plans and demanded to cancel it (it would be to noisy, to high, etc.). In substitution for the GIB, Six Flags build the original Boomerang, it was less noisy and high so the neighbours approved it. But then again, today, the whole neighbourhood still complains about everything like the noises the park produces on normal operation days. That's the reason why Psyké Underground, the Shuttle Loop, had to be fully unclosed. Otherwise, it had to be shut down. Yes, the park has some idiots next door (Some of them even demanded to fully enclose the Intamin Freefall 'Dalton Terror' for it's noisiness. Luckily for the park, they don't have to do that... ).

That would be cool though. Yeah, but very expensive I guess. Another fun coaster fact thanks to Vijfzintuigen.nl: Wodan, the GCI wooden rollercoaster in Europa-Park (Germany), wasn't the original name for the coaster. They planned to name it after 'Thor', but because Marvel has the rights for the name 'Thor' (thanks to the movies, they claimed the name for everything, what is kind of silly because it's a Gods name/Myth) they had to choose another name.

Projektion Posted May 21, 2014 Share Posted May 21, 2014 In the original plans/models of Portaventura, Dragon Khan was originally going to be an Arrow looper with intertwining loops. These pics were discovered by Willy on PA-Community. I get the feeling the intertwining loops is what gave B&M the idea to add the "threading the needle" moment on DK before the zero g roll.

gerstlaueringvar Posted May 22, 2014 Share Posted May 22, 2014 Can anyone explain how the anti-rollback system of Intamin coasters like SkyRush, i305, Mega-Lite model, GeForce work? Can't find any information about this online. Also, how does the Gerslauer spinners' silent lift work? Link to comment Share on other sites More sharing options...

linearinduction Posted May 22, 2014 Share Posted May 22, 2014 For Most "Silent Lifts" there is a Magnetic Strip of Steel Parallel to the Teeth and as long as the train is moving at a certain speed, the magnetic force causes the Anti Roll Back Dogs to remain Up.

rcjp Posted May 22, 2014 Share Posted May 22, 2014 ^You're right. I had heard about that for the superman ride of steel coasters. But the system used on those seems different from the one used on skyrush, for instance. Link to comment Share on other sites More sharing options...
linearinduction Posted May 22, 2014 Share Posted May 22, 2014 ^ Don't know how accurate this may or may not be, but I had once heard the Magnetic Strip was built into the Track of MF. Link to comment Share on other sites More sharing options...
rcjp Posted May 22, 2014 Share Posted May 22, 2014 ^Maybe that grey strip next to skyrush's anti-rollbacks has to do with that. Link to comment Share on other sites More sharing options...

I don't know if this is right, but I read something about MF that if the train is moving, a generator runs a motor that keeps the "dogs" up. If the train "drags its dogs", it produces a loud noise that can be heard a ways away. Link to comment Share on other sites More sharing options...

If the train "drags its dogs", it produces a loud noise that can be heard a ways away. A weird thing happened one time I was on MF, the trained stopped about halfway up the lift and when it re-started a few seconds later I heard the sound of anti-rollbacks as if we were on a traditional lift hill. The sound kinda reminded me of Goliath's (SFMM) lift hill Link to comment Share on other sites More sharing options...
rcjp Posted May 23, 2014 Share Posted May 23, 2014 ^Interesting. I also noticed that when skyrush is starting to go up it initially moves quite slowly and sometimes you can hear a noise which may be from the anti-rollbacks, so I'm guessing it also uses that system.

gerstlaueringvar Posted May 23, 2014 Share Posted May 23, 2014 ^&^^ Yes, I remember hearing some pretty loud anti rollback noise when Pandemoniums start to go up the lift but when the chain speeds up, the noise disappears. Link to comment Share on other sites More sharing options...
