42129 - 4x4 Mercedes-Benz Zetros

[1974]

Yeah? However, four outta five EB members will buy this anyway ..

[nerdsforprez]

20 out of 5 will complain about the price....

[thekoRngear]

I think that is the novelty of EB. Criticise hard, complain a lot, get the set out, buy it silently, then mod the set to #make_Lego_great_again

Repeat the process.

Yeah well maybe they have a point? 

[1974]

Nope. The vast amount of pins we get these days have never been cheaper!

No, all those numbers are integers.

[1974]

Those are rookie numbers, we will ALL complain about the price, buy it anyway, mod it properly and move on to the next wave ..

Maybe EB should apply to that job at TLG?

What, all of us? Think it'd get a bit crowded over there...

Well, we're all just keyboard warriors. Sum that lot up and we might a single decent designer

And "open source" either regarded as one entity or as mass effort always wins. In the long run.

Well, sorry to disappoint you coupling-haters, but I managed to couple 2 PU C+ Xl motors with no gear reduction and a simple diff. So far no gears torn apart, but lots of tire shredding! 

But by the look of it, this set might bring back some of those green pieces from 42039, which would be a VERY  good thing.

Why wouldn't it be possibles to hard couple them? As long as they motors have the same specs it's absolutely doable. You even don't need a diff. The differences between same type of motors are so marginal that it doesn't do any serious harm. @Philo tested it some time ago here.

It might also be wise not to address people and put them in groups. I don't understand why anyone should be disappointed. Instead focus on arguments. There are valid ones against (security) and for (performance) hard coupling motors.

I don't see anything wrong with hard coupling motors so long as the gears ain't breaking or cracking.

The question was not whether it's doable, of course it is, but whether TLG would do it in an official model, as there hasn't been an example for it, and we were wondering why.

 

[1974]

That's why it's not a god idea

Edit : Lol, and for us mere mortals it's not a good idea either

I know. I was just specifically referring to @Scoar Sonander. @1974 just posted why it wasn't done before and will likely never be done, because for TLG security > performance. Not to speak of stress which is applied to parts and can decrease live expectancy of them.

[allanp]

That's true for PF XL motors but PU XL motors don't have as much torque. 

[gyenesvi]

@1974 Those are good references for what can go wrong with too much torque, however, I was wondering if the situation changes with the use of new differentials and portal hubs, that put the down-gearing and thus the high torque only to the very last sections of the drivetrain, so less load on axles. Furthermore, in my experience, the hub stalls the motors anyway, so it’s not really forcing them to move when the vehicle is stuck.

[Brick-a-brac]

Hi guys! I’m the creator of the video @Jundis has shown to you. I will give a short summary of my thoughts on this topic in the following post. Please excuse that my English is not the best.

First of all, yes, the 4 pictures exist. I won’t swipe on a switched-off phone with black screen ;)

The leaked picture we have seen on several social media platforms are from a catalogue for retailers and don’t show the final version of the Zetros. As @Jundis said, the biggest change is that the Zetros will only have 2 axles instead of 3. The colour has also changed (black and green). There will be many stickers, some of them with the lettering “Zetros”. The Zetros will have motorized functions due to 3 PU L-Motors and 1 PU M-Motor. My source that gave me the pictures claimed that there will be a gearbox. I can’t see any differential lock on the pictures, so I think there will be “just” a gearbox. In my opinion, the M-Motor will shift the gears. The Zetros will have an independent wheel suspension with red Technic springs. I couldn’t find out for sure if there will be new smaller tires. The wheel hub might be the one from the 42099, but on the wheel rim there might be a new (?) part I haven’t seen before. 

Furthermore, the used parts are mostly like we would expect from TLG, I can see red and yellow technic axles and 3 studs long blue Technic pins.

Let’s talk about the validity of the pictures and why I can’t show them:

-        Firstly, two independent sources told me that the final version won’t look like the one we have already seen. The source that didn’t send me the pics claimed that the model will cost about 330€-350€.

-        Secondly, my source that send me the pictures answered the following to my question, if she/he might know more about other sets coming in summer 2021: “[…] lego mario/ Luigi”. I You may ask “What’s so special about that?” and I also didn’t really think about that little hint for a long time. But a few days ago, stonewars.de announced that we will definitely get a “Lego Luigi Starter Course” – similar to the one with Mario – in summer! To sum up, my source seems pretty valid to me.

-        Thirdly, even if it’s fake (what I don’t think), then just the pictures might be fake. Since two independent sources told me that the Zetros will look different than on the leaked picture, it is nearly a 100% sure that at least the reduction of 3 axles to 2 is true.

Unfortunately, I can’t show you the pictures I got, because both of my sources work with Lego in a certain way and might get in serious trouble when it can be tracked who they are.

Finally, I would like to explain the discussion about the cancelling of the Zetros: Since the 6x6 version is mainly used in the military, it seems to me that cancelling the set might have been an option for TLG, also because of the fiasco with the 42113 Osprey. But I guess they redesigned it instead, which would perfectly explain why the final version will only have 2 axles instead of 3. However, we also know that even the 4x4 version is used in the military, so there could exist other reasons why there was a reconstruction of the Zetros (like lacking stability, maybe the 2 L-Motors were too weak for 3 axles, …).

 Edit: I have looked at one picture that shows the model from the bottom for several minutes and I have to say, that there could be a differential lock, but only (visible) on the rear axle. It seems like there is a gear (the orange one from the Bugatti Chiron) right next to the differential but I really can't tell if it is just for the gearbox or a differential lock

Let's say that all of posted by @Brick-a-brac is true, I have one question - can you post us at least one more thing tire dimensions?

It is really hard to say if the tires are new. They look like the old ones but when I take a really close look and compare them with the ones from the 42099, the wheel rim looks slightly smaller than on the 42099. But it's really hard to see, since the rim of the 42099 is black and the one from the 42129 is light bluish grey. The design of the tires are very similar to the ones we know. The notch on the tires seem to bee a bit softer and rounder, but I can't say that for sure.

How many treads are on tiree on your images Luca? Xerion (set 42054) has 20 treads on tire 107 x 44 and Jeep (set 42122) has 16 treads on 56 x 26 tire.

Thanks

[Brick-a-brac]

I could count 18. This means, they really could be new.

Thanks; that means tire is 81.6 x 34-38 ( most likely) on wheel technic racing small 43.2 x 26.

Now let's hope that there will be some other set like Ninjago or similar theme using same tire to get them more often since I need about 20 of them for my ongoing projects...

Kind regards
