Introduction: New K'nex Roller Coaster Propulsion System
This is a new K'nex Roller Coaster propulsion system that uses 2 wheels instead of using a chain. Very practicle. These steps will show you how to build the main part, then you add it to your roller coaster. It uses 2 motor. For me I have one that always run- on motors(left) and one that is remote (right) but you can put 2 run-on motor also.
Step 1: The Support Base
Make this! This is the base that support the tracks. You may not have to build that if you just want to add it to your roller coaster.
Step 2: The Tracks
This is how the tracks need to be made, but you can modify it to fit on your roller coaster.
Step 3: The Motor Assembly #1
This step is to make the frame of the two motor assembly. You need to make four of them.
Step 4: The Motor Assembly #2
Here you add the motors, wheels, rods and spacers to build the propulsion module. LOOK CAREFULLY
Step 5: Assembly #1
In this assembly, you have to connect the motors to the tracks.
Step 6: The Final Assembly
Now install the track on the base support, add elastics to pull the motors upwards, install the tubing on the tracks, and you're ready to go.
IMPORTANT
If the wheel don't grip the wagon adjust the elastics to be tighter.

nice other than the video not working. i might have to do something similar for the coaster im currently working on. but first i have to buy more tack so i can actually finish it. at the moment it's 2.20 meters tall (7 foot 2.5 inches).

Finally, an interesting k'nex instructable. There's a first time for everything. Good job.

Are you trying to confuse us or are you actually saying something nice?
Reply 14 years ago on Introduction
No, I'm not trying to confuse you. It's genuinely refreshing to see a k'nex instructable that's not a crappy gun. I say plenty of nice things, just not usually on K'nex related...anything.

Then you may like my new thing - Even if I built it about a year ago, it's cool, k'nex, and not a gun.

these have been around for a long time. you can make this only use one motor by applying a chain to the gear.

this is cool, a chain works better though but this is more realistic
I'm working on a knex coaster blue streak for Cedar point

Looks cool. Do you need multiple motors to get it up to 3 feet (as an example)? And where is the remote controlled motor from?

nice idea! i might add it to my new coaster in construction... see pic! it is going to be as tall as my ceiling (aprox. 10 feet tall). How do you like it so far?
