Never seen such a negative review from a well known reviewer. We already had pretty big price increases over the past years, but then at least there was a lot of positive to say about these sets. This one is just a disgrace to me.

Just rewatched the "grabber" piece 20 times, I love these kind of original mechanisms. Also, the last video with the circular track: what if you make that into an arcade claw game: let the train run at fixed speed but have the user control crane turn speed and grabber simultaneously; should be pretty challenging then to grab a container.

Yeah, I went through many iterations with the train. Complicated does not seem to work better, this fairly simple design worked best. Make sure to have you top wheels to roll extremely smoothly. Bottom wheels only add friction, so here it are only pins so they don't actually touch the track (except for on the lifthill where in this case it's obviously needed)

About a year after my first roller coaster (https://www.eurobricks.com/forum/forums/topic/197576-moc-roller-coaster) there is now v2. Widened the track from 7 to 9 which gives a bit more flexibility which came in handy especially for the lift. Still limited by the fact that you loose a lot of speed quickly, but at least I managed to get an inversion in as well as to get the trains around the track without some extra help. Started to run out of certain parts, but I also began to run out of table anyway ;-) There actually is a car in this picture: Transfer track. Underside of the trains is rather simple, but after many attempts this turned out to be the most "efficient" (in terms of keeping speed) solution.

Is by that definition a roller coaster a vehicle? Are illegal building techniques allowed?

We see enough super cars etc. This is really original. Love the seats.

Thanks guys, I'll get myself an Xbox controller

Not really a building question, but also not worth opening separate topic: Is there a (most likely not Lego) device capable of controlling two (or more) Control+ hubs? Something like a Playstation controller. I really hate having to use my phone to use the Control+ hubs for multiple reasons: building Lego is for me a way to NOT be on computer or phone for a few hours, I might need the phone to take pictures, I hate configuring these apps, but most of all: I want physical buttons to feel like I'm controlling my MOC. I know you can use the BrickController2 App with a Playstation controller, but I'm really looking for a standalone solution. So something like this, but on steroids:

Soon we'll need a lawyer to write the contest rules ;-) But joking aside, that's a very clear rule.

I like these kinds of builds that show a lot of "out of the box" thinking. Very original work.

Ah, a man of culture! You're right about that, the diameter is too small so probably putting more stress on the wheels which will limit their effectiveness. Also I've learned how important it is to make sure that the track should not move (it still does at that point). All energy that goes to track moving is wasted. For v2 I'm thinking about trying to recreate (more or less) Oblivion from Alton Towers.

Thanks for the feedback. Next project will be Roller Coaster v2. From what I've learned building this I think there's still a lot of room for improving the system so that a more realistic one should be possible.

Warning: If you are easily upset by illegal building techniques turn back now! About three decades after my first attempt I finally managed to create a roller coaster using Technic. Like a real roller coaster it's "gravity powered", though I couldn't make it to run a full round without the "booster" in the middle. Station: Top of the lift hill: First hill / turn: This was probably one of the hardest pieces, creating a "backbone" in a way that the track would follow this nice curved decent: Entering the booster section: S-bend after the booster: Same location, different angle: On the final hill: Last small hill, last turn, and back in the station: Front car, inspired by one of my all time favorite roller coaster: And this is how the wheels look: Video! https://player.vimeo.com/video/909478768?h=fca928686e

Happy to see you've time for Lego again; hope to see the model at Lego World!

Thanks. I didn't count but it's certainly a lot more parts than the Liebherr.

Instead of buying the overpriced Liebherr I decided to make my own giant crawler crane. It's just a generic one, not based on a specific model. - Three XL motors in the bottom for left/right drive, and rotation of upper structure. - Three L motors above the turntable: raising long boom, raising upper boom, winch. - Up to about 2.2 meter. - Driving is a bit sluggish and the lower boom has the tendency to move a bit sideways when turning. Apart from that it works suprisingly well (given that I had never build something close to this size). (I'm well aware my camera is pretty bad, sorry for that).

Building one now and also like it a lot. Really interesting mechanics. However I do have a question, what is the idea behind the new gears (https://rebrickable.com/parts/69779/technic-gear-20-tooth-with-axle-hole-opening/ and https://rebrickable.com/parts/69778/technic-gear-12-tooth-with-axle-hole/ )? Then don't seem to add any value; they are just the same as the 20 and 12 tooth bevel gears but with less flexibility. Only reason I could think of why TLG should still make gears without "bevel" should be for chains, or am I missing something here?

Impressive how you managed to get so much functionality in there!

Amazing work! I guess a nice extra design challenge would be to change the "programming" in such a way that you could directly "code" the segments that need to be lit up instead of coding which ones need to change.

That looks amazing! Can you place some bigger pictures? The current ones are like one pixel per Lego part ;-) Edit: thanks for placing bigger pictures.

I have a picture like that, will remove it

nice work on the angled outriggers
