Theme Park Discussion / Inversion or Not?

I was watching a Hydra video on youtube that TPR put up and I noticed someone left a comment saying "the cobra roll isnt a cobra roll unless you actually go upside down". Obviously I disagree with this moron... but it made me wonder. What degree of banking must a roller coaster hit to be considered an inversion? Is there actually an "official" degree to be met or is it just whatever the park feels like considering it?

Here is a photo of Hydra's inclined-diveloop which is considered an inversion.


And here is the cobra-roll.

they'll try and get anything. it's all part of advertising saying, "the cuntstuffer has five breathtaking inversions!" even though it only technically goes completely 180 degrees upside down twice.

This in an endless debate, and it always results in "there is no exact definition of an inversion, so just follow your intuition", and "if it looks like a duck, swims like a duck, and quacks like a duck, then it probably is a duck".

I agree.

I would say the inclined dive loop isn't and the cobra roll is. But I go with what RCDB says, and if they class it as an inversion, then it's an inversion.

Hell no. That isn't even close to being upside down really. I'm not sure why they classify it as an inversion. But they are roller coaster n00bs and they probably got technical while discussing it.

I always classified it if the track banked at 135* or more, as it is closer to upside down than horizontal at that point and that seems to be what this is going on.

First: No, and how anyone could classify that otherwise is beyond me. That "loop" goes sideways at best. In fact, it more closely resembles an overbanked turn than an inclined loop.
Second: At least they tried. But yes.

That is some good logic right there.

Ohh this is always tricky. Compare this with Hydra, then,


I'd say neither are inversions myself.

Yea, I never really did think there was an official degree for inversions. Like Maverix said, I've always gone by rcdb.com. My guess is coasters like Millennium Force and Texas Giant say are advertised as "so many" degrees banking without going upside due to the fact they have lap bars and maybe the general public would freak if they advertised them as going upside down with only lap-bars... who knows though.

Speaking of Texas Giant. Has anyone attempted something like it in RCT yet?

^^no its not one...

guys this isnt really hard. i look at it as if i would fall out my seat at the "peak" of the inversion, would i land on my head? for the cobra roll, hell yes... for the inclined dive loop i would say yes too even though i slightly agree with louis. not the clearest inversion but it passes.

people also always forget that this isnt roller coaster tycoon where the element is always going to be perfect. b&m create roller coasters to adapt to speed a g forces and hydra is a beautiful example of that

and NO who ever said that sucks at life... really bad

Nah, I don't think it's an inversion. But still pretty sweet anyways.
