I'd normally agree, but since this set does use planetary hubs with very high gear ratios, the forces on the driveline in a case of a locked diff would be really low. Bigger issue would be tire wear after prolong usage.

Agreed to the first point. I don't think there will be a significant degradation on the tires, given the use outside. The model isn't that heavy the tires would wear out. Also there has been a Jeep model from CADA using diff locks before.

Additionally, LEGO would never promote (again) RC sets for outdoor usage so from their perspective it is not a problem :)

What set did they promote for using outdoor ?

In the first pages of the instructions, Lego usually shows a drawing that explains that the model is made to be used indoors.

Looking closely at the app screen shown in the catalogue, it seems as if the Zetros will get a similar setup to the X-Treme off-roader, with steering on the left and accelerator on the right.

For example the set 8675 which had a pretty descriptive name - Outdoor Challenger ;)

Yeah, I highly doubt this thing is designed for outdoor use, especially given that it can be stopped by a pebble.

Well, that ones are fully true RC machines that have only molded LEGO's logo at their parts...

[AVCampos]

They're not totally unrelated to other LEGO: the shock absorbers they introduced were used at least once in "regular" Technic, in 8420.

TLG won't release a set with diff locks.. the feature on the diff that makes it possible is there for mocs only. Locking it and then playing with it can smash parts and TLG won't release something that can self destruct. It will never happen, but it keeps coming up on new model releases!!! Its none-subject, for so many obvious reasons.. forget about diff locks...

But they do regularly omit the centre diff in 4x4 vehicles.

Motorized 4x4's tend to have separate motors for each axle, so no need for centre diff, while manual models don't usually stress parts enough to require a centre diff (though it's sometimes included for the sake of functionality).

The Unimog has one, though that admittedly doesn't have a powered drive.

But your favorite 42070 B model has one

It's not my favourite, but true. It's a good system as well - I think it'd work well with the Zetros.

Mmmm... thats a good point!

I'd love to see something clever done with C+ and diff locking... even a manual locker would add whole new function to the model which helps with the price tag. I just don't think we'll see it.. which is a shame. But i'm still excited to see the details of this set. The tow truck looks a great set, this has great potential too. Fingers crossed!

[Maaboo the Witch]

Here's a fairly close real-world approximation of this thing. It'd be great if the set had a spare tyre tucked away somewhere as seen here.

Two spare tyres would be great, lol. Then it would be much easier to put the third axle on there.

From the looks of it, the Hub is behind the cab, but no spare tires in sight. I guess i better get my 600 euros ready lol.

Looks quite outdoorsy.

I personally wouldn't copy anything the dumb kids in this image are doing, considering they're running the tyres backwards and couldn't even be arsed to attach the chain to the bull bar properly.

And don't even get me started on the positioning of that bear...

Looking at the tire tread... tires mounted the wrong way, maybe?

Yes that was meant by @Maaboo35 when he wrote tires running backwards....

Self clogging tread

Probably filmed in a studio that looks outdoors lol. TLG  would not want to break their own rules.

Has anyone been able to identify the element on the front wheel hub?

I'm talking about the Zetros, by the way.

Do you mean the planetary reduction hub?
