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. https://www.flickr.com/photos/168123198@N08/45159348804/in/photostream/ https://www.flickr.com/photos/168123198@N08/sets/72157702098098561/

I've never seen any kind of chart like that for the whole of Lego for all time, No. It would be very interesting to see! I wonder if Brickset has one or any of the other websites like that, Bricklink or Rebrickable, etc.

In 1988 it was 8865 Test Car. I was starting my family, so no money went to Lego. I certainly wasn't going to buy "toys" for me. I eventually bought the parts to make it in the nineties. Then, in 1994 it was the 8880 Super Car. Ooh!, I wanted that one, so many cool new parts. In the nineties, I didn't know I was an AFOL. I thought I was the only foolish adult that wanted Legos!!! Two years ago, I could have bought it for $100 but no longer wanted studded Technic. Now, I have a nice collection of Technic Lego. And lately, it's roller coasters.

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.

Thanks very much for the clarification!! Yesterday, I successfully made Ultraviolet's cable modification (above). Now I can use my old 9V buggy motors with an IR receiver and RC remote control. I also recently received some batteries with smart technology to stop overcharge and over discharge. Love it!!

I want to make my own. Thanks for your response. So connecting the C2 and 9V wires to the "+" 9V battery wire, usually red wire. And then connecting the 3 remaining wires together is correct (C1, GND, and "-" 9V battery wire, usually black wire). This is correct?

UltraViolet, If a person wanted to make something like a 9 volt lead connected to a PF cable, how should it be wired.

It seems to me you would want all pictures to be taken from a single point of view and distance. That way stitching them together will look right. Maybe I need to understand more about what it is you are working on. Is this a digital file or actual plastic?

See my post from May 2.

Sorry this is so late. I have been working on a MOC. The parts orders take so long to get here then you find out you needed something different. Then you order again, and you do that seven times and still more is needed. Anyway, 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.

Whoa! zephyr1934 that's a lot of parts!! And, a whole lot of creative thinking Whew!! Here is more from Masao Hidaka: Pretty cool!

@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.

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.

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.

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.

That's a brilliant idea!! The only thing that may happen is the parts on the gray axle may begin to slide out of their places. I would suggest using a 4262 (technic plate) with a 3743 (gear rack) attached in it's place. Of course it will also require a different bit of framing for this to slide back and forth.

I do like Molded animals best. But, in some cases, like a camel for instance, they are so expensive! I think even brick built ones would be cheaper. Building an animal to minifig scale is impossible in many cases.

I have immensely enjoyed Lego for over 57 years, but Technic is my absolute favorite theme. I was thrilled when it came out!! Thank you Jan and Sten!!!!!!!

TechnicBrickPower, Excellent video!! Nice tutorial for Stud.io. If all the stud.io tutorials were as well done as this one, I would probably, finally learn how to use Stud.io.

Thanks, djm! I will try that. I did get an email from Trevor Sandy, LPUb3D programmer, He referred me to this explanation: https://github.com/trevorsandy/lpub3d/issues/412 I was on vacation when I got it, so I didn't get this updated.

It's a true story picture of what happens to people who trust Jesus, passing from death/hell unto life/heaven, Even the clothes change to WHITE. Thank you Lasse!

Cute! Cute! Cute!

Looks Great!! Would like to know how are you powering this loco? On your Southern Pacific EMD MP15AC you used a little bit different batteries.

This looks Great!!!, just like the real ones around here.

That's a great looking ship, especially the rigging.
