42129 - 4x4 Mercedes-Benz Zetros

[msk6003]

Or maybe we get

2 XL for drive

1 L for steering with automatic difflock(like @KevinMoo's monster truck.)

1 L for 4 speed automatic transmission

1 technic hub

[HectorMB]

Well, I think that putting the price in context with previous models (42099, 42100), the Zetros will have 1 hub and, best scenario, 4 motors. To elucubrate about the functions is indeed rather the reflection of our desires than the real possibilities, in my opinion. So, to me, to consider that as a fair or not-that-fair price, will fall on the functions and, if at the end, they're indeed 4 motors.

OK we have new tractor tire size!

Claas Xerion tire - 20 treads - 107mm diameter

ZETROS - 18 treads - expected size: 80~86mm diameter (81,6 in my opinion)

JEEP Wrangler Tire - 16 treads - 56mm diameter

You are 99% right.

Based on some calculations I took today and yesterday it looks indeed like it will be 81,6 x 34 tire

Finally found the pic, Looks like a mock trial truck so already better than all previous RC trucks and should run much better due the the smaller size/weight. A few thing make me wonder; the high price might be due to 3xl motors for drive and the front axle seams static due to tire clearance but the rears seem to not be double wishbone (the frame structure is wrong and the is a large gap above the whole axle, could just be bad picture though) I would say sprung pendular. However as I think u can see though the whole model at the rear axles it does make me wonder if there is something else going on with the rear suspension like live or bougie systems but I doubt it.

Anything but all three solid axles would be a complete write-off in my books

Hmm I'd be very disappointed if they use the same principle as in the 42122 rear suspension. A live axle really is a must here. According to the pic it's unlikely, but maybe the left front tire is in the compressed state of the spring? Like going over a bump....? Just wanna spread a glimpse of hope...

That exposed motor looks a bit ugly. Maybe there'll be a sticker over it like in 42114.

Not to digress but ... I've never seen a large truck like that with large/ribbed tires. Those are typically reserved for off-highway, and used mostly on agricultural machines.

I think this is also an omission of Lego, I was hoping for normal road tires!

Do not post pics from that catalog yet. It is still confidential. I have removed it for now. 

 

Okay, thank you!

[DrJB]

I just saw a picture of this on a different thread and something seems odd about such vehicle. TLG used large/ribbed tires. Those I've never seen on trucks, they are typically used on off-highway machinery that moves relatively slowly, such as agricultural machines.

Edit: It seems my post was 'copied' to a different thread. Neat, did not know you could do that..

Those "tractor" tires are also quite commonly used on trucks, too, usually for specific terrains.

Up to 80km/h

...it looks like Zetros is trial truck and lots of trial trucks use tractor tires

[DrJB]

Yes, good point. I was referring to most common applications. That video of the tractor going at 80 km/h seems to indicate the tractor has some fancy/active suspension. I drove some large Case IH tractors, and those tend to be 'bouncy' (large tires), add to that the ribs in the tires, and you get a lot of vertical vibration... especially on hard asphalt.

here just Zetros has a device for agricultural machinery, and the trial version is not such in life.

And Kamaz is another story!)

I had a pleasure to test drive smaller Fastrac (4220) and it us very comfortable; full suspension (both axles), cab and seat suspended; steering wheel is easier than in my car and Trac had excellent air conditioning...

Really looking forward to see those mid size tractor tires in my hands when they'll be available.

Yeah, I moved your post regarding Zetros to the Zetros topic, so we can keep the CAT topic clean

Agreed. That Zetros on the pic is adjusted for agricultural purposes. But those tires can also be used as Lego decided, for offroading.

I'm so glad to see we are getting the mid size tractor tyres! A JCB 3CX comes ever closer!

You can make a remake of 8455 with tractor tires then 

[Polarlicht]

Where can i find pictures of it?

Best pneumatic set ever - 8455

[Polarlicht]

Hehehe, thanks for the DM. Looks really cool. Might get this one as well. I like the bright green. 

Just Hope its not another terrible offroad 42070...

[Mantarri]

Would someone mind "not" letting me know where to find the leaked pics in a DM (not the thread)?

You cannot ask publicly for a leaked photo here in the forum thread(s). Ask him for the photo(s) through Inbox. The post is removed by the Page it seems.

I wonder what the performance of 42129 will be like compared to 42099. Assuming smaller tires, planetary hubs, and solid axles, I don't see any advantage except for more torque on a straight incline, due to coupled drive motors. Unless there is a really amazing suspension and drivetrain.
