If this doesn't belong here, please move it to a proper location.

I'm starting this topic for you to share your Roller Coaster MOCs, Ideas, photos, links, etc. There doesn't seem to be a Theme for Roller Coasters, so here we go. 

Here is my current project.

Yup it works. I am waiting for parts from Lego to make some improvements. Hopefully I can make a video in a month or so.

The problem is with the wheel mechanism that brings the coaster around the half circle at the top. If that system is disengaged, everything will run smoothly. But obviously you need the coaster to go around up there, whether you crank or power it.

Some MOCs use a 24738 track immediately following the chain and they do not use those wheel mech's at all. However this requires a redesign. I developed some work arounds that have increased the speed of the chain and wheel mech and cuts down on gear friction. That idea helps a lot but still is jerky and slows down. I am now thinking about powering the wheel mechs separately from the chain mech.

One day later... Problem solved! I got the chain running smooth and the wheel mechanisms working smoothly too. If you are interested, let me know.

Your rollercoaster looks awesome!

On the topic of rollercoaster loops, @Masao Hidaka's recent YT video blew me away in terms of his super-creative solution to get loops and drops built. Here is the video:

@Masao Hidaka has some great ideas, especially simplifying the superstructure. I don't like building those supports on set 10261.

Here is a great entry on Lego Ideas https://ideas.lego.com/projects/0847c721-c370-4d4c-b58a-336a39c7e4e4. He has simplified the whole thing using "non brick built" supports thus making it easier to build more affordable. I wish Lego set 10261 was more like this. Consider supporting him.

The idea of turning curved track sideways to get a roller coaster loop has actually been around for at least 20 years.

But it is A LOT easier with the roller coaster track.

Those supports look great and the whole build has a great form.

Thank you so much for sharing my ideas project. Below are lastest 2 of 20 videos.

There are five slow-mo shots at different angles start from the middle of this video! Added a small gimmickThe cars always hit and swing the vintage part of Finland flag 360° every time it make the banked turn.

 

The truss structure make it easy to attach Christmas light strip for night ride!

Whoa! zephyr1934 that's a lot of parts!! And, a whole lot of creative thinking Whew!!

Yeah, those were some insane builds, it even uses 12v power rails as structural elements

Here is another great idea for roller coasters : the Drop coaster;  It has an elevator!!  https://ideas.lego.com/projects/56b31583-12c0-42f0-9250-6694be3ffe90

LEGO GBC Roller Coaster Scary Mimi This one has a pusher at 0:11 

Is your chain drive running a little jerky on your 10261? The problem is the wheel pushers at the top rail. If they are disengaged, the chain runs smooth! I have disengaged mine and designed a separate motor drive for it. It works great! I have also modded my chain drive to go faster.

So many roller coaster MODs are using support girders instead of stacked bricks with an axle. TLG needs to consider this building technique for the next big roller coaster set!! It would be a little cheaper and much easier to build and MOD.

Check this out!!

https://www.hellobricks.com/2018/11/looping-parfait-lego-10261-rollercoaster/

A perfect looping (and a genius idea) for the roller coaster LEGO 10261 Rollercoaster

History not to talk only Black Friday and LEGO novelties, let's change some of the subject with this impressive custom version of the LEGO Creator Expert 10261 Rollercoaster set : to look even more like a real roller coaster, Florian Lochner had fun doubling the circuit with a bonus curve and a looping loop, while keeping a very compact ... Finally, barely larger than the original set!

The stroke of genius: turn the rails 90% to perform the looping. And it works perfectly ... Is this something that LEGO had planned in the design of its rails or is it just a happy coincidence? The result is in any case both aesthetic and effective!

For the curious, the circuit is controlled by the Mindstorms EV3 which controls four M Power Functions engines: one for the climbs, one for the wheels located in the upper corners, one to open / close the doors of the passenger loading dock (with an infrared sensor), and one for the output of the train.

@1963maniac, How did you make the spiral on your coaster, as I have been trying to make my own version and I have been failing miserably.

992bricks, Some life events have stopped my Lego hobby lately. The building instructions are here:

https://bricksafe.com/files/1963maniac/10261 - Modifications%2C Couplings%2C %26 a Feature.pdf

Satan's Spiral is the last item in there. The drawings cannot flex like ABS plastic, so they cannot be drawn correctly.

These instructions are intended for expert builders or better they are not easy at all! Any questions, just ask.

If the BI has problems, please let me know so they can be fixed. I hope you enjoy these!
