red 16 -tooth slip gears

That's probably not the case, because one of those gears is supposed to be driven by the motor.

That's what we're talking about! If there are only two gears, then in fact they both cannot be sliding gears (with pin hole).

What exactly is meant by "sliding gear"? I think it is like the 8-tooth one, it can slide freely on axles. I might be wrong.

[AVCampos]

That's my understanding as well. To me, the gears that rotate freely are called "clutch"... even though that's not the best name: the only true LEGO clutch gear is the white 24T.

[R0Sch]

Didn't think a gear color could start such a long debate. They are both same sized, axle driven 16T gears (just count the teeth on 1/4 circumference). They look different in size in the 360 animation because of the upward tilted frame and perspective view.
Maybe they made them orange because of material or design change, like being able to slide on the axles like the red 8T.

How about:

• fixed [normal / bevel / double bevel]
• freewheeling (e.g. https://www.bricklink.com/v2/catalog/catalogitem.page?P=87407)
• sliding (red 8-tooth from 42009 https://www.bricklink.com/v2/catalog/catalogitem.page?P=11955)
• clutch (e.g. white 24-tooth https://www.bricklink.com/v2/catalog/catalogitem.page?P=60c01)

Or, if you want to distinguish between simple freewheeling gears and those that can be engaged/disengaged:

• fixed  [normal / single-bevel / double-bevel]
• freewheeling (e.g. https://www.bricklink.com/v2/catalog/catalogitem.page?P=87407) [normal / single-bevel]
• freewheeling with clutch (https://www.bricklink.com/v2/catalog/catalogitem.page?P=35185). [single/double/toothed clutch]
• sliding (red 8-tooth from 42009 https://www.bricklink.com/v2/catalog/catalogitem.page?P=11955)
• resistance clutch (e.g. white 24-tooth https://www.bricklink.com/v2/catalog/catalogitem.page?P=60c01)

Wonder if the cockpit display in the app changes when the vehicle flips?

The app automatically switches screens to match the vehicle when the model flips

I really should read those things more. That's quite clever!

[yetkopempo]

Fyi, this is the video that they used to create the Lego official pictures: https://youtu.be/yphyKpem6yY

It shows how the vehicle flips and climbs onto things and how thw wheels are moving on an uneven surface.

Another possibility is that these gears are simply 16/20T gears without any special features except for the spur-style teeth. These alone should allow for chain compatibility, which would be nice, and ought to allow for at least a bit better efficiency, since their side profile isn't rubbing supporting beams as much. This would be largely a waste of a mold, but could happen nonetheless.

[Ngoc Nguyen]

What are the exact shade of "blue" and "yellow" in this set? Is the "blue" regular blue or dark azure? Is the "yellow" regular yellow or the new neon yellow?

[jovel]

In that video, those gears appears to be blue.

Maybe that's a prototype?

It’s definitely regular blue. Compare the color of the pins to the blue parts. Same color. It is probably the new shade of yellow though.

Thinking about the new gears a bit more, it would make sense to make a non-bevel versions of 12 and 20 tooth gears to be used with chains for the future 1:5 scale motorcycles too.

[AVCampos]

That would be a welcome addition indeed. But not in this set, as having only spur gears instead of their bevel versions limits the potential for single-set MOCs due to their inability to change the direction of movement. This is also why I think the 42095 would have benefited from having pairs of 12T-20T instead of 16T-16T (that, and being able to configure for speed or torque by swapping gears).

Corrected "42096" to "42095"

I was hoping for a 10 tooth gear because you can connect it to an 8 tooth diagonally if you have a 2x2 array of pin holes.

That would reinforce the theory that these are 'real' new gears. If they are just recolours or non-bevel 12/20 gears, it makes little sense to produce a different colour for prototype.

I know this variation is meanless and useless but how about clutch gear but with axle hole? You can connect it with driving ring and also normal axle.

Because in order for it to have any use you would have to have two axles in series that can be meshed or unmeshed using this gear and a clutch. but if both axles are driven then the clutch will get put under stress because the teeth on the clutch wont always be alighned or moving at the same speed.

You could do as you explained in a few ways anyhow, without needing such gears.

An adapter between driving ring and axle would be extremely useful sometimes, but as @SNIPE says, it couldn't work in a single stud thickness, because it would need to stabilize two disconnected axles. I recently designed and 3D printed a part that works nicely in these scenarios, looking like this:

How about similar thing, but not female side of clutch insted use male side of clutch. This will be usefull for simple power coupler.

I guess we're getting off topic, but I suppose that could be useful for PTOs and the like, so maybe I'll model one sometime; I don't know.

That piece would be very useful for an RWD/AWD switch for example..

As for the orange gears, it's pretty difficult, as none of the above proposed scenarios seem flawless so far. Based on the images and counting teeth, I like the proposal that it's a non-bevel 12T / 20T pair, but then it's very unlikely that both sizes would be the same color, no? As for theories with 16T gears, I believe the orange color would be too close to the red clutch gear, and would probably give too much chance for confusion in future sets.
