hang on

how could anyone give this less than a 5...

its only at 4.09 with 60 rates..

not boasting, but the acr has only 34 rates and equal overall rating.. and im sure there are others


People give it bad raitings jsut becase they want their guns to be the top ible.

THAT, is why!

thats the dread thing about this website.

They shoudl make it so you can see who rates what. If any ones gonna rate it anything less than 3 stars you need to post a comment saying why.

Can you make an instructable on the station?

possibly... but it's so easy to make that roof I'm sure you could figure it out in minutes.

I just made a similar roof on a micro knex coaster. I use micro because that's what my parents have been getting. I've got serpent spiral, dragon's drop, lava launcher, and loopin' lightning. But of this style I've only got storm mountain and rippin' rocket.

knexjay (author)2009-09-13

hey burrito i make lots of roller coasters out of knex and every single 1 i make i can never seem to make the turns actually turn they just stop

yeah turns do do tat but if you lube your trains and make the track smooth that handle the turns a bit better.

thanks *replys late again*

Roller coasters are simple to make. Look at the track, and make your own based on it. There is no point in making a rolled coaster instructable.

Not always. Sure they're easy to make basic ones at first ,but it's still pretty hard.

buy every knex piece you ever see ten I'll think about it lol this think used 10 sets each 45 dollars.

HOLEH CRAP!!!!! This is EPIC!!! it is amazing!!!

Serial-Cricket (author)2009-06-14

It's alright. Bet it took a while to build, so I give you props for that. 4*

Owenmon (author)Serial-Cricket2009-06-15

What do you mean "alright?" This is probably one of the only K'nex creations that deserves a 4.5 - 5 stars!

Serial-Cricket (author)Owenmon2009-06-15

I'm just not a fan of it. I personally like the CHAOS ball machine better.

DJ Radio (author)Serial-Cricket2009-06-29

this isnt a ball machine, this is a roller coaster.

Serial-Cricket (author)DJ Radio2009-06-29

I know. I was saying that I like the CHAOS more than this.

That's messed up.

That is seriously messed up.

Okay, I am searching everywhere to figure out how to get the long train cars for these coasters. Can someone please tell me how to get them ? do we have to make them? is there a site that sells them? Thanks, Eric

screamin' serpent has them along with the track. Ebay's the only place to get them.

i tried to feed the screamin' serpent cars through the boosters, but they don't fit. do you have to mod the cars?

no you have to mod the boosters. The little flaps the go over the rotating wheels need to be cut off. this wont degrade the quality of the boosters at all. It's more of an upgrade :) You also have to tape some card board on the side of the car to get it to launch.

ah thanks alot. i dont know why i thought of that before.

Welcome :) Are you sure you dont mean *"I don't know why I didn't think of that before"*?

oh yeah haha i need some sleep

Owenmon (author)ericbusby2009-05-31

You just need to get a couple of screamin serpent sets. Then use the middle car in each of them for a longer train. Here's a list of how many cars you get per set : 1 Screamin serpent set - 3 2 Screamin serpent sets - 4 3 Screamin serpent sets - 5 4 Screamin serpent sets - 6 5 Screamin serpent sets - 7 6 Screamin serpent sets - 8 7 Screamin serpent sets - 9 8 Screamin serpent sets - 10 And so on.
