Wow! I've never seen an S-model before! Do you think you can get through the whole alphabet? That looks like a clever and creative model, too!

Never underestimate the willingness of the rich to spend ridiculous amounts of money for high-quality stuff! My rough guess is that the electronics make up close to half of the price, but the other half is a ton for the bricks required, even accounting for the high amount of effort required to collect them all.

Those are clone MouldKing ones. I've got a bunch of them, and appreciate the very low price and good quality. Their small cylinder and pump even have metal rods!

Thanks a lot!

I would love to see a new Bronco released, at a sufficient scale to realize its details. Where have you heard about this other upcoming SUV? I'm not familiar with it.

I just saw it the same place! Now I have to nitpick their article. "BuWizz, a Slovenian firm that specializes in making motors for Lego cars and scaled-down trains." I don't think they make motors for scaled-down trains. Batteries maybe, but not motors. "It then stuffed 15 of its electric motors into the toy" Five of the motors weren't really their company's. Oh well, I'm glad to see you getting some relatively mass publicity!

Thanks! I just tried changing the axles to bars and the bar to an axle, but I don't really like the result. It bends more easily, and ends up having a much more significant angle between the cylinders in the opposite direction as before.

While fidgeting with your V1 design (while trying to do homework ), I came up with this even more compact, yet strong, design. The 4L bar should be replaced with a 3L one. A 3L axle can be used instead, but it puts the assembly under a lot of stress.

Sweet! I'm pretty sure that bumping an old topic when you have something really worthwhile to post (like this) is fine, and probably preferable to starting a new thread. I've never needed these cylinders doubled, but I've messed around a few times with setups for it. I really like your V2 design and its compact symmetry. I also notice that on that design the little L-shaped parts can be put on two different ways to touch the edges of the cylinders slightly different amounts, allowing for some fine-tuning of the tension, I suppose.

I think it could be a possibility. Just maybe they'll use some of those dark green panels from the botanical sets and build it in British racing green.

I'm back with the second MOC in my drivetrain model series, after my Koenigsegg Jesko one. I've always been very inspired by Sheepo's old Porsche 911 model and its amazing gearbox. Sadly, I've been able to learn very little about the working principle of this gearbox, with only one image available of a part of its structure plus a text description. Anyways, I've always wanted to emulate its dual-friction-clutch 7+R design with the secondary motor for applying the clutch pressure (I have made dual-friction-clutch designs with the entire shifting done by one motor. This was in my early days, before rotary shifters!), and I have done so here, taking advantage of newer parts to (I assume?) make a smaller design than Sheepo did. The overall model consists of the engine, the transmission, and the differential, plus a stand with four motors, four switches, and a rechargeable battery box inside to control the functions. The four motors control: Drive Shifting Clutches Differential lock Drive: A PF L-motor drives the drivetrain, branching off to run the large-scale boxer-6 engine, which has the correct crankshaft design allowing the opposite cylinders to extend and retract at the same time, unlike most Technic engines, and 120 degrees of offset between each set of cylinders, which is more realistic than it could be, but probably not completely realistic. The other branch goes to the gearbox. Shifting: I have tried to explain the gearbox and its operation, but it is very complicated and hard to explain in text. If you really want to understand it, it may be more helpful to watch my video below. The gearbox, as a dual-clutch design, is split into two nearly symmetrical halves (Reverse throws off the symmetry). The drive axle from the gearbox directly runs one of the clutches, while a 14:20:12 gearing runs the second clutch (directly above the first one) at a very slight speed increase. After the clutches, I have a 28:24 ratio from each clutch to its respective gearbox. The use of 20 and 16T clutch gears in these gearboxes provides one speed difference, and the fact that the axles holding the driving rings are connected to each other by a 16:12:20 gearing (using quarter stud spacing) makes for another difference. The gearbox connected to the slightly slower clutch has the slowest gear reversed, making the gearbox a 7+R. After these gearboxes, a 8:16:12 ratio (more odd spacing) connected each gearbox to the output shaft. Shifting was done with two rotary shifters hard-coupled to each other and connected to a PF L-motor in the base. This also ran an eccentric mechanism at a speed 4x faster than the shifting (Thanks to 12:24X12:24 reduction to the primary shifting), which slid a large assembly back and forth to select the correct clutch. More on that later. Clutch: There were two separate friction clutches, composed of two sets of 30mm tires being pressed against each other. To engage the clutch, a tan 4L axle with central stop was pushed by a long lever. The axle then pushed a black 4L L-beam into the one wheel, engaging the clutch. These two long levers were engaged by a pair of black wedge belt wheels which slid back and forth due to the eccentric on the shifting drive, causing first one clutch to be engaged, and then the other. A PF M-motor could also rotate the entire assembly with the wedge belt wheels in order to engage or disengage the clutches. With the clutches disengaged, the car would be in neutral (though the differential usually rotated intermittently and weakly because of friction between the technically disengaged clutches). Differential lock: Another PF M-motor operated a very simple rear differential lock through a linear clutch. Overall, I was pleased with the model, though the clutches didn't really move far enough to engage as much as they could have or disengage as much as they should have. Otherwise, though, I was pleased with the complexity and unusual mechanism for shifting between clutches. More images at: https://bricksafe.com/pages/2GodBDGlory/porsche-911-drivetrain-model

I did my usual procedure of copying a set in LBG and then stuffing in high-performance third-party electronics to this truck, and had a lot of fun! I made it work with the larger wheel covers and 81mm balloon tires, used a modified version of @Herny007's headlight design, and even added anti-roll bars front and rear because the truck kept rolling over. I got the truck up to 21km/h on the flat, and 26 downhill. Unfortunately, right after replacing the battery, it seems that my motor has blown, so I won't be able to do a formal presentation. Here's one image from before I added the motors. If any of you are curious about the mods I did, let me know and I can take some more pictures--until I take the thing fully apart, which won't be long. I really did like the set, and it was the perfect platform to motorize like this, making for a fun, good-looking toy with a minimum of effort.

Very nice! I love the complexity, especially in that crane arm. I also never really thought about how much harder it is to add crab steering to a 6-wheeled vehicle. Usually just adding an extra motor for the rear axle can make 4-wheeled crab steering work well, but it looks like that wouldn't work for a 6x6. I'm also using those MouldKing pneumatics (That is what you have, right?) and have been very pleased with their performance and price. That's me on practically every MOC I make

It sure is! It appears to be exclusive to a Scala service pack, and not even one of this set is for sale on Bricklink!

Or, as I mentioned earlier, they could model the Porsche Taycan, which is electric, but also has a two-speed gearbox. A two-speed would still never replace an eight-speed in my eyes, though.

I won't say it's not possible, but previously these sets have generally helped market newly released cars, while the Audi R8 is already nearing replacement.

I'm excited!

Do you have any plans to try something like that? The fastest Buwizz powered car I recall seeing was around 40km/h, so I'd love to see you really push the limits!

Very nice work! I love the way that Buwizz can do "marketing stunts" that really engage with fans--including ones that demonstrate serious building capability like this one. Great job! Do you think that removing a lot of the strictly unnecessary weight (door and spoiler mechanism, interior, etc.) would get you a faster record, or would the lowered weight lower grip enough to make the handling at such high speeds essentially impossible?

Those are some interesting points about the torque difference at part power. In my experience the PF motors seem to perform better though, at least for fast cars. I think that PF has better response times and that the electronic protection is less restrictive, allowing for quicker acceleration. I haven't tried a PU crawler, though.

Very interesting! Is that black gear on the side 3D printed?

The plan was the rather predictable car-into-jet-aircraft, but I think the way I was planning on achieving it would be fairly unique. I'm rather excited about the challenges this model would present, so I expect I would build it, contest or no.

Personally I'd prefer a wider scope, but that's probably mostly because I've already got a vehicle-to-vehicle transformation planned out. This is just my preference, though, and it may not actually make for a better contest.

As a third option, you could always try to emulate Red Green and do it with a K-car and a boat trailer! I think that would be an awesome contest entry, actually... I've already got my imagination fired up, though, with a completely different model in mind. Does anyone else find that planning models is more fun than building them? Thanks for starting contests and sparking ideas!

Interesting!
