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

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 ❤️

Knex Coaster 1 looks too intense for me.

This is every kid's dream

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.

First Date: Hey let's get out of this bar and go back to your place. Engineer: Um. No.

really waiting for a POV camera of it. I would love to see it using a VR :)

Wow! This is super impressive! I built coasters with K'nex from when I was a kid until I was about 27. This is amazing!

Woah, this is incredible! I love the idea of filling an entire house with K'nex like this. You're living the dream for sure, excellent work!

Brilliant build - very streamlined and no clunks. The fact it's so well integrated is amazing.

This is amazing how big it is, thank you for sharing!!!

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.

Imagine bringing a girl home to this 😂

Congrats on beating my record! That is awesome! The sound on that drop is so intense but it also makes me cringe every time . . . thinking about those poor wheel assemblies lol.

That's so awesome. That hallway drop is insane. I want to ride one in real life

THAT IS AMAZING!!! 🤩🤩🤩. well done for such a large and complicated build . It runs so fast and smooth too , love it 👌🏼🧱👍🏽

Awesome work, this is a really cool roller coaster! Makes me want to get back into Knex again haha

smashing , im getting back into knex cant wait to purchase the sets

This is amazing! You did a great job. Keep up the great work!

This + VR would be epic AF. Amazing job!

I hope this never gets taken down

It goes really fast!

Simply incredible!

He actually starts showing it at 6:27

Nicely done!

Awesome job !

Dude this is awesome! Great job!

First person micro camera would not change the weight much. 1"×1".

That was really impressive well done

That's awesome!

This made my day

Wow!! Amazing

That’s pretty cool set up on your roller coaster 🎢 assembly wow

Epic man!

Awesome!

This is AMAZING!!!

Super cool.

This is so cool dude !

This is insane!!! But so good!!!

I spent all my teenage childhood with 7 sets, lol. I missed hearing the chain and gear click'edy'clack noises. lol.

WOW im impressed considering this is before quarantine

that is super super awesome

My daughter loved this stuff

Get some lights on there! Awesome layout.

Amazing! I can practically feel the wheels getting destroyed on that final drop! are you going to do a gopro pov soon?

Awesome!!!😁💪

AWESOME!!!

Amazing

Very cool. Would like to see them back to back, if that would work.

What a clean home for a single man...

Teacher : the project will be easy! Also the project :

That’s awesome

Dude. You deserve more from youtube.

Awesome

You be playing Roller Coaster Tycoon in real life!

Holly shit! This is something I would have done if I had the time and space! My whole room was k’nex contraptions when I was like 13!

I dreamed of something like that in the 70s when I was a kid

Hey man, Id like to know where you get your hands on all your parts? Do you just buy multiple coaster sets?

Very nice. I think you should keep the half loop inverted and pull off a twist afterwards

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

Me at 6:30 when you show the mega drop: “I AM SPEED”

I like the loopy pillar in the corner

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!

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

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.

Your brain is so expansive it makes my mind boggle I'm guessing you're an engineer by trade either way great job 👏 👍👌

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!

oh its fantastic.. imagine I am riding this craziest roller coaster..wooh! xD!

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

His LEGO coaster looks awesome!

Can you please show the entire ride of this? Like put a little camera on the kart and let it record the entire ride. This looks so amazing I wish this was a real coaster lol 😂

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!

this is bad ass and a work of engineering art, you should be working for a coaster company

would it be possible to put a small camera on the train?

What it is the end?

How much did the pieces cost?

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.

This is ridiculous and amazing! 🤣

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

Is this still set up in your house to this day?

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.

hi i have alot of sets and extra parts for are you looking to buy stuff

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

I’m 44, and that thing is bad ass…

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.

I would love to see a first person POV

Very nice, I wonder how much you would charge to build it for me including the K'nex pieces. Love to have something like that set up permanently

imagine having to dismantle all of this. the physical and emotional labor

How long is it? Duration and ft

Now you gotta add lights for night mode!

This is RAD!

any way you can find out its top speed?

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 !

What happens when you have to move?

nice

Hello I just found out about this. My kid nephew is about to be 11 ...is this suitable for him? If so, which would you recommend first? Also they look quite flimsy?? Your rollercoaster build looks amazing!

Did you go to ucf? I saw a magnet on your refrigerator.

does anyone know the scale comparison for k'nex I was hoping to figure out what this would be like if some crazy fool decided to make it life size

Damn you got like the best roommate ever

This is absolutely insane!

We need a POV on the ride!
