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.

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

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

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!

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!

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.

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

I hope this never gets taken down

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.

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

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

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

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

This + VR would be epic AF. Amazing job!

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

Dude this is awesome! Great job!
