The World's Longest K'nex Roller Coaster - An Overview

It's been in construction since October 2018. Coming in at around 240/250 feet long, it's what I believe is the world's longest roller k'nex roller coaster.
If you have any questions or comments please let me know in the comments! I'd love to hear it.
I have a few ideas for videos I want to make in the future that aren't related to K'nex. We'll see if I get around to making them!

[@CoasterGeek987]

I’ve been getting a lot of comments asking for a POV and a lot of criticism for not filming one. Due to the coasters construction, a lot of things would need to be modified to make room for a camera on top of the train, especially in the spaghetti bowl section. The POV would also be extremely boring, you can see all the straight sections that don’t really do much. That being said, the whole circuit is featured, so I’m sure you can imagine what the POV for the ride would look like. Thank you for all the kind comments, the love, and the support. This has gotten much more attention than I ever anticipated. I’ll probably make one more video of the coaster before I move in July ❤️

[@EatMyYeeties]

If you do consider a POV recording, an FPV camera is really small an light, so that could be a good alternative! I think most people (including nyself) just wanna see the drop in FPV!

[@CoasterGeek987]

Smile Space the train goes so fast through it I would probably need to slow it down. I’ll look into cameras and see what I can find. Thanks!!

[@Sintarzus]

@@CoasterGeek987 search for the ones used for racing quadrocopters. They are very small and reasonably cheap, but with a quality of old laptop camera.

[@mikeymike7431]

POV would be fucking great still man!!! Maybe slow the video down here and there tho

[@dilldozar296]

CoasterGeek987 well actually pinhole cameras are cheap and as small as a finger pad. They glue on.

I would disagree. My dream isn't straight track, my dream is inversions and airtime and theming.

[@chadbroski9438]

[@alpsoysal3586]

Did some calculations bc I was intrigued (and have nothing to do): Just after the drop, the coaster car is going just under 9 m/s (32 kph / 20 mph) assuming a 4 m (13.5 ft) drop (and no friction). The centripetal acceleration in the curve at the end of the drop should be about 80 m/s^2 or 8 G!!! But this only lasts for 0.2 s due to the speed of the car. Assuming the curve is a circular arc with 1 m (3.3 ft) radius (the curve is almost certainly not a circular arc but that should make the max even higher, and I determined the radius by eye.) Assuming the car does not lose any speed in the short straight section below the track, the half-loop after the drop is even tighter and the car experiences double the acceleration as the curve has about half the radius. That is a deadly 16 G acceleration. No wonder your track is undergoing mechanical failure around that curve. Source: am an engineering student. If there are mathematical errors, I'm blaming my Casio calculator.

Boo Casio. Sharp all the way.

[@CoasterObsessed]

I have taken the record! Insane job on the coaster. You get a new prospective of how long it really is when your building it.

[@CoasterGeek987]

Your model is a lot more interesting than mine. Love all the launches and the transfer track is super cool! Congrats!! Was working on a 2.0 version of mine but it collapsed a few weeks ago so I had to scrap it all 🤣

How do you all design these things? You gotta know that technology and then you got to be able to actually build it all. I am duly impressed. Before I read your pinned comment, I was thinking gee, I just watched someone else's POV of their ride, why didn't this person. But as I saw the cars go around, I came to the same conclusion that you mentioned about camera height. Nice ride.

I think you got a little bit too greedy on that drop but still WOW it motivated me to build again!

[@lentjansen1052]

Cool

[@c0nsp1cu0us2]

Cams like Gopro and Handycam would be way too heavy but perhaps using FPV micro quad POV parts could be the way to go. They also make all kinds of rainbow LED tunnels and rings for fpv indoor quad racing. I think adding things like that would make the POV experience super entertaining, Id probably watch it 1000 times. Anyways amazing work, keep it up!

Kafj302 I have no idea but it would be really big

[@dooshdoosh4312]

The g forces on this thing would probably rip the track or coaster apart first of all, if not that you would definitely die from them lol.

[@DryEyeBuilds]

Okay, I wasted my time with this.... If one knex figure is about 3” and we could assume they have a height of 5’8, four of them stacked atop each other would be a foot, or a scale 22.6 feet, meaning that 13 foot drop would equal 293.8 feet. However, the 17 foot hill would be equivalent to 384.2 feet. Not the tallest on earth, but around there.

[@starofeden9277]

nice

[@benjaminfrancis9399]

I’ve been wanting to build one but I can’t find the track or trains anywhere so if could send me a link to where you can buy the track and trains that would be great

[@LtZerge]

yeah trying to source the old 2000's style knex parts for this would be a pain, you're going to searching used and ebay for a while to find anything good. However k'nex has been producing roller coaster designs consistently for years, they just use a different track system now than they used to.

[@justins6458]

I would love it if you had any still images of the track and supports particularly from underneath . I am trying to do something similar to this and having trouble with some aspects of the construction. I tried pausing the video but ten it get too blurry to see individual pieces. I love your work!

[@DrummingWriterTrekfan84]

This is s amazing! how many k'nex coster sets did you buy to build this?

[@FireDragonYT63]

His LEGO coaster looks awesome!

[@erngarcia7693]

This is SO COOL!!! Can you make a POV video lol J/K

[@Beetlecop]

I like the coaster a lot, but a more linear edit of the footage of it running would have been great, showing the coaster operation from zone to zone. Next time! Great work on the coaster!

[@williamworth2746]

I went to a building expo at the Franklin Institute when K'Nex first debuted they had Giant models constructed of the sets. They were literally giving the product away as a promo if you built something you got to keep it. My father also got a few of the sets back then they came in a plastic case packed full of the basic parts. The blue box was massive and you could also buy a motorized kit separately the came with gears and the old school DC Worm Drive motor. Sadly today sets are a shadow of what they once were.

[@johnharris2683]

you need a little FPV first person view drone camera . they make them really small and with a couple of 1 cell LiPO batteries we could get a first person view of the roller coaster itself !

[@damienhuff2726]

Please post the point of view footage from inside the car. Please please please please.

[@FrIeDeGgS887]

I think any gopro or something would be launched out from that 17ft drop if he tried, lol.

[@LtZerge]

@@FrIeDeGgS887 There's a wide selection of small and light action camera's on the market designed for use in RCs, the gopro is great and tough as nails but it is certainly way too bulky for this kind of thing.

[@liammcfarlin3923]

It would be cool to know the forces the coaster puts out and how much they would be scaled to a normal size person

[@mahdithabarber1354]

Dope hasn’t been none made in awhile.

[@myndexinc]

If you were to do a POV, then a small dashcam would work well in a modified car, but IMO you want a camera that shoots at 120 fps, so you can play it back at 24 or 30 fps for a reasonable/realistic speed.

[@naggrasnchicken]

Would love to see that first drop in first person! I wonder how fast it’s going after that drop (in both real and scale speed) and how high the drop is.

[@rennethjarrett4580]

Put Zoom oil on the moving parts especially the roller train wheel axles. On your lift chain, if you run it often, you need to have idler sprockets on the return side before you wear the frame through.
