Feat of Engineering
on July 5, 2022

I don’t often find myself writing reviews for anything. But this set blew me away. From the elevator with operating counter weight, to the stop at the platform for new passengers to get on while the elevator was in the air. There are so many cool and impressive design techniques that just were awesome to put together. I also felt like there were a lot of new pieces I hadn’t seen before either which was cool, although I would have been ok skipping the step that made you put all the small chain links together. I would definitely recommend anyone who is on the fence about this set get it. It won’t disappoint and was one of my favorite builds in a very long time. This will definitely be a set I rebuild a few times simply because of how cool it was to see everything working together as I was building it. And the sheer size of the completed model is very impressive.
I would recommend this to a friend!

Loop coaster is so much fun and to me worth it!
on September 22, 2022

This is my first Lego build and review and I am hooked. Yes the instructions can be hard to understand, but if you have patience, you can build this 3700 piece coaster. One piece of advice is to ensure not to rush through it and TAKE your time. After I assembled everything it took another hour to figure out why the car would not run on the track smoothly. All the Lego’s must be tight!!
I also hooked up the motor and it will run forever if I want it.
My next project is the lighthouse and after that the extreme 4x4 vehicle!

Lots to Love with Loop
on July 8, 2022

I only have two complaints about this otherwise fantastic set. There are so many interesting build techniques, and I wasn’t even sure how it was all going to come together, but by the next to last bag I started to see the magic and fun in this build. The experience goes by a little too quickly, which is my first complaint. The other involves how the coaster cars transition from the elevator, to back on the track. There’s a slight gap between the elevator and the coaster rails, so my cars kept missing the track on re-entry. It took me a lot of time fiddling with the counterweight and support columns to get the elevator/track to line up at an acceptable level. I haven’t had a chance to try out the Powered Up functions yet, but I feel like that automation will make this set shine as a display piece in my city. Kudos to the design team. Truly an engineering marvel.

Good but needs constant adjustment
on July 21, 2022
Posted by: GleefulInfernox024
I enjoyed the build of this one, and the final product is both a great display piece and fun to operate. However, it's important to check the build each time you use it, as various connections will come loose, specifically on the tower itself. The first is at the very top, where the lift mechanism connects to the counterweight tower, and the second is the top-most horizontal bar connecting the lift to the tower proper. The good news is that - so far - these are the only two spots that seem to come loose, so it's an easy fix; moreover, once these connections are secured, the coaster works flawlessly. Not a super big deal, and given the stress put on these connections during operation, not surprising. That said, the coaster could be greatly improved with some stronger connections at these (and other?) stress points.
I would recommend this to a friend!

Machines Need Maintenance … or Optimization ;-)
on August 1, 2022
Posted by: StartledSandwich046
This set was a lot of fun to build - interesting support structures, slick design, very well thought out.
That being said, you have to be spot on with the instructions, then build on your own to modify behavior you don’t like. Cracking of gears, slipping of chain, misaligned lift, these are all fixed if you reduce chain length, check your axle connections, verify parts are put together right, etc.
Some tweaks are always necessary - it’s a precision machine after all. I personally was annoyed with the top part, and had issues with the counterweight coming off the track, the counterweight track coming loose, and the top separating. My fix for this is attached - top block is rebuilt completely - Teknic parts to both stabilize the counterweight wheel and apply pressure to keep it from separating - SNOT pieces added to hold the the top of the track. You may not be in the same position.
The tweaking IS the fun part, but I think the key thing to remember is that if all is tight and it won’t run stock for a minute or so, there is probably a build mistake and you should recheck things. If you want more than a minute or so of runtime before you need maintenance, it’s time to customize.
I didn’t expect nor WANT perfection out of the box. This is Lego’s coaster when it’s stock, but now that I’ve tweaked it for me, it’s MY coaster.

Excellent engineering, satisfying build
on July 8, 2022
Posted by: JeffP
If you thought the Haunted House was great ride engineering, wait until you see this. The vertical lift system is brilliant and remarkably reliable. The station is beautifully designed. Everything looks like it could be real. My only minor quibble is the use of stickers for a set this expensive. You also may have to invert the pins for the rubber band on the advance wheel, otherwise there isn't enough tension to keep it engaged.

Disappointing but beautiful- won’t recommend
on October 15, 2022
Posted by: Canblower1
It is heart breaking to review this beautiful and specially designed kit. It has enchanting characteristics like it’s hight, the colorful curves, the 11 mini figures beautifully dressed and prepared to roll through the coater; the hot dog, ballon and pretzel carts, at any rate, a spectacular scenery and details that should have made it an amazing kit. But, and there is the “BUT” which stains the effort placed by the artist/engineer who spent endless hours designing such a wonderful kit that does not properly work as expected and makes an engineering marvel, a small flaw of engineering in the eyes of some, and I. I do have to echo the voice of those who found a flaw in the elevator system, a flaw that takes away most, if not, all of the ability to play and fully enjoy the total beauty of the Coaster. Manually, raising it is a disaster! It is almost impossible to raise the track and coaster car at a good pace without jerks due to the ratio of the gears! And when they get to the top, they try to leave racing out, most times derailing. Amazing how fast they go down the slope and how neet they take the loops! That is impressive! Then they come to a stop, some of the times, that is if the track has not slammed down and is out of alignment or worst! I tried the power up function and the situation got even worse. The motor is too fast; the tray mostly stays half way and the coaster carts smash against the lower stop or came out of the track; in other instances the coaster cart already was down and the elevator smashed down against it! I tried a different slower type motor, the large low rpm, and it kind of worked better but still the counter weight had difficulties! One thing I noticed is that the tower, no matter what I do to it, it alwasy has some curvature, it is not perfectly straight. I used some crazy glue to prevent some of the bricks from coming loose since I understand the weight is not rhe problem but haven't had the time to sit and play more with it. I guess it has not been a good seller, I bought mine the same night it became available and it has never been backordered as I expected! Truthfully, I was going to purchase another for a nephew but after my experience, decided against it. I am sorry not being able to give a good or better review on this one. I am a Lego enthusiast and lover of almost 50 years; have built hundreds of intricate and multi thousands brick Lego's! However on this one, well, I beleive it still needed some work before turning it to us. Perhaps some retrofitting will be available later for use to purchase or free and fix it or better yet, we will work some fixes on our own!
No, I would not recommend this to a friend.
