Re-creating a very small, very tame Arrow coaster in Cedar Point, first opened in 1976. (Kronos is put on hold until I've had MUCH more experience with B&M and Arrow is easier to understand and construct for me at this point.) As you can see, I've gone much smaller for a little added practice with Arrow-style coasters, which should eventually lead to me re-releasing GASM, but I can't say if that will be soon. If I do, I intend to add 3D-s and scenery to it, and what better place to start than here?

Pics: FINAL VERSION!!!

the Corkscrews are a little too stretched out

just wanted more people to critisize.[:D]

Anyone there?[8)]

I can't continue until I'm sure the shaping is correct, and having never been to Cedar Point ([:O][V][:I]) I'm a little bit handicapped as to what I can do.

I've progressed as far as I can on my own with the track.

I think you need to re-shape your loop, as well as the entrance into the corkscrews and you lift crest/lead-in to the drop.
There's a few pictures and a POV video on the Cedar Point website that could be of some help.

OK... re-shaping.

Lift hill transition is now more gradual:

Loop has been tweaked to be more "Arrow-ey" (long rise and descent with the inversion occuring very quickly). The track has also recieved numerous adjustments to make the inversion occur more smoothly.

And the corkscrews have received numerous minor adjustments (mainly the entrance and the exit, they have also been made tighter). I have compared this element to an off-ride POV and the pacing and speed looks to be pretty much correct at this point.

I've started adding trees and such, but those only exist around the leadout right now.

Oh, and the calculated track length: 2053.29ft

You?????????re loop still doesn't have the right shape. Look at this pic?????????

The loop needs to be an tear drop shape.
The corkscrews have a little miss shape to them as well?????????
Notice in this pic, the twist mainly happen on the enter and exit of the element. From approx 130* to 230* the car twists slower (larger span) than the entrance and exit.

Hope that helps!

it's the best video of corkscrew EVER.

And it's also the vid I've been using for comparisons since I started. [:D]

Your loop's shape is off a bit. Also make sure all the track elements are based on plain circles without anything resembling a smooth transition or lead in.

I already altered the shape of the loop, and yes, I have designed the transitions on this ride to be (kinda) forceful.

I'm now beginning to work on the supports (at least, just for the lift hill right now).

As for that loop...

EDIT: I will be leaving my home for a vacation in New York soon, so this project is going to be put on a 1 week hold. I will be visiting SFGA while I'm there, as well.

Some more pics, this time of support work:

And I think this is as far as I'm going to go with this for now. I have a vacation to prepare for.[:D]

Supports are looking good. The loop looks pretty close, but maybe a little bit too round on the bottom.

The hill needs to have a quicker transition into negatives and a quicker transition back out. When i went on it, it popped me out of my seat very fast and popped me back down really fast and then gave me two headbangs going into the loop. (how did those head bangs happen there? i dont know but it happens a lot)

The hill needs to be abrupt transitions no airtime at the the highest point but at the transition between going up and leveling out.

Wow, I'm actually being asked to make my track rougher...[8D][8D][8D]

Well, that's easy, a couple over-streched beziers, and that's it. (Magnum XL-200 POVs taught me the finer points of Arrow Airtime, the transitions are extremely abrupt, as if the train is snapping itself into that section of track, rather than settling like Intamin or B&M models do.)

The transitions are rough because there is no smoothing done between each section. That first hill on CP's corkscrew goes straight from a curve upwards to a curve downwards, without any change in the radii of either curve or a straight section in the middle. It's hard to get that abruptness when building by hand but it can be done.

Also, the corkscrews on these older models (as well as some of the current models) are perfectly round. Think of a perfect circle, with bankings that are perfect. The bankings on these usually are 0*, 90*, 180*, 90*, 0*, or 0*, 35*, 90*, 145*, 180*, 145*, 90*, 35* 0* [:)]

Finally, the break I was looking for.

Just returned from SFGAdv today, and I finally got to experience a true Arrow (GASM).

So, with that experience (rode it thrice to ingrain the ride into my head), I think I now have the info that I need as to what needs to be done.

Next step when I get home: grab a CD. It might turn out useful for perfecting the shaping. [:D]

Well, now I'm finally home. Vacation was great, and very enlightening in terms of roller coasters. Now I can get back to work with a REAL sense of what is expected.


The airtime hill has received tweaks to make the entrance, element, and exit more circular (with the help of a CD for shaping referencing this time):

http://img41.imageshack.us/img41/2768/c ... 202200.png

And the corkscrews have recieved an overhaul to massively improve their shaping (once again, with a CD to help out):

http://img30.imageshack.us/img30/6254/c ... kscrew.jpg

So, it does indeed seem like the final track shaping and smoothing might be nearing its closure.[:D]

Final track length: 2043ft.

So, after a G-analysis, I have the following:

-Floater air time over the hill with very quick swapover from positive to no Gs, and again quickly returning to normal as you exit the hill.

-Gs are within limits for the loop.

-Quick floater pop entering the straight segment

-Headsmacker entering the corkscrews.


As this is an Arrow coaster, the headsmacker stays, I wanted it there (you can't call it Arrow if you don't bang the riders heads at least once).

Make sure your airtime hill is parabolic. Looks pretty good! And 7 feet is easily acceptable for track length difference.

^Those aren't parabolic, they're more circular in design. Hence "jerk hills".

Where were you 5 minutes ago? That's great![:)][:D][^]

Well now I think I can safely say: you want jerky, you got jerky.

The top post has received The Billboard, or my current progress into this project. At this point, I am DONE with the track.[:D]

watch the video again. The hill after the drop is still wrong. You have a strait down the first drop. BOOM your curving up BOOM your curving down BOOM your curving up into the loop.

Done. Tested. It replicates the video very accurately now: as in, immediate transitions. [;)]

The supports have been finished (all pre-fabs are gone, as well) and the track has been tunnel-tested and passed.

The ride itself is finished. Now I need to start on the scenery. The picture library has been updated. (Please ignore the pre-fabs in pic 4 of the loop, they are gone now.)
