42140 - App-controlled Transformation Vehicle

[Zerobricks]

I mean, sure the new gears (at least the 20 one) could have the clutch pattern and a cross hole and even slide on the axles without friction

Well, I guess this snapshot confirms different sized gears after all. Maybe 12T+20T or 14T+18T spur gears. The latter would make more sense to widen the ratio possibilities since 12 and 20 already exist.

Cool picture! So in this one at least we do have two different colors of gear--it would make more sense for these to be the final colors than that orange/red, since they're different from each other, and from preexisting red gears.

I really, really hope for 14/18, since the 4n+2 gears would open up plenty of new possibilities for gearboxes.

Like for a new UCS car? It sounds great, really.

Has anyone else noticed the penguins in the background on the "exploration vehicle" side of the box?

Just noticed. One was praising how awesome the C+ app is, the rest two are not! Jokes aside, this is probably to subtly emphasis the set's transformation capabilities.
There is also a ship which is probably stuck in the ice frost even before the set was announced

It's kinda odd what the new gears are for. They don't seem to do anything that the double-bevel variants can't do, except not rub against beams, which is more of a design problem with the double-bevel gears than anything else. Adding even more same-sized gears might only confuse things further. And why the weird coloring, if there's nothing special about them? Doesn't really look future proof.

On the positive side, good to see the 19x3 frame in another set, and the yellow parts seem to be the new neon yellow color.

They can drive chains.

Yeah it does seem odd that they did 12 and 20 tooth again. Why not 14t and 18t for the new gears? And hopefully those bright blue colours are only to match the colours of this set, and we get them in more tasteful colours in future, hopefully! At least now we can use chain drives on 12t and 20t gears now. But it is nice to see the 3 x 19 frames, rubber grip pieces and the transformation feature seems to work quite nicely.

[Erik Leppen]

@Ngoc Nguyen Good point. Didn't think of that.

That is a very interesting set, much more than I thought. Shame about the new (almost) useless yellow parts, but new blue parts are always welcome in my book.

[2GodBDGlory]

So, we do have new gears, but they're much less useful than they could have been... Still, they look cool! I suspect the best use of them will be to get a 1:2 gear ratio in flexible spacings using 12T and 24T gears--sometimes you need a specific ratio like this for something to work, and this should make it more convenient. 20:40 would also get us that ratio, but takes up a lot more space. I suppose it'll also open up some ratios that never really showed up before, like 12:16, but overall, I'd much prefer the 14/18 combo I was hoping for! I guess my old-school 14T gears ain't obsolete yet!

[Zerobricks]

Here's another theory about the new gears. The teeth look much wider and longer than usual bevel versions, so I would assume they are stronger. Maybe they have a project that needs a stronger version? Also as mentioned before they are now compatible with chains.

Arctic vehicle would look good with 42038.

[Ngoc Nguyen]

 

Well it's certainly... something.

It's a bummer not to get 14T and 18T gears, but that would have been a pretty pointless ratio for the drive. I guess they had to make the 12T and 20T spur gears because the double bevel gears were not robust enough for this rough play feature.
You can clearly see the spur gear teeth are not only wider but also higher and closer to a base involute without any profile shift. The new gear will definitely be more robust due to lower contact pressure from the higher contact pattern they offer.

Good to see a clear shot of the new frame piece. I can see lots of people using that for chassis designs. Don’t think I’ll buy this set but do think I’ll be hunting for some parts

That's an interesting idea, could be part of it. On the other hand, I'd guess they could be useful even if they are not stronger, simply because they potentially run smoother. For example, in a complex gearbox that could make a difference, don't you guys think? Also, the grinding issue someone mentioned; I often find some plastic dust around the bevel gears in my RC models when I push them hard for a while (even with standard technic hub and 1.2V rechargeables). Maybe TLG is trying to address these issues with the smoother running gears.

Yeah, I'd agree that smoothness is likely more of a motivator then strength. After all, have any of us ever broken a tooth off of a 20T or 12T gear? I haven't, at least, and I tend to use stuff hard.

[msk6003]

Conspiracy theory of introduce new gear

-TLG don't like people making alternative model out of it's set so remove one feature to hard to make alternative model out of this set.(If TLG use bevel type of gear, than people can make narrow drivetrain with 90' connected both gear)

 

Set itself

-Very interesting motor's rotation direction is changed when vehicle is flipped. Screwed hub is suck as many people think.

UNBELIVABLE. REDICULOUS. NO NEW GEAR SIZES.

I've been watching UnbrickMe's YouTube videos for like two years. Kind of good to see someone got the 42139 and 42140 sets early to give us a review. This guy is good and is improving except for the fact that he quite persistently thinks the 42114 aka Volvo A60H is the best set ever that Lego produced which he also wanted to claim under a different username here in EB and got bashed for it in 2020 iirc  Besides that I have no problem with most of his views and thoughts. While it is kind of good and feels fresh to see he triedgiving a building process review similar to Racingbrick I think no one does it better than Balazs himself. As for the set (from his perspective),it seem nice and fluid. A good spiritual successor to last year's C+ Buggy. BTW, will it only flip when it faces resistances/obstacles or the user will also have the power to flip it according to his choice?

[TechnicRCRacer]

Did anyone notice that we have our first Technic parts in the new Neon Yellow? This is awesome! I will definitely get them off B&P, but this set looks like a pretty good parts pack as well. Disappointed about the gears though.
