I think even a two-level car transporter would not come with multiple additional cars. There is plenty of playability in including only one car, and it makes sense to leave room for additional cars sold as separate sets. I did some googling for possible licenses. With the existence of the corvette I had the idea the car transporter is from the same license. Seems no go though; all the image hits I'm getting for car transporter and chervolet or ford gives them loaded on volvo carriers, or photographed from the back so I can't see the brand. So if it's licensed, it's not from the same deal as any of the already-released cars.

I think I'd rather see the spider crane be motorized with LAs than with pneumatics. A car transporter could easily have two or three times as many parts as the cars it carries. If those cars are the bugatti and the porsche you'd be looking at 6k parts minimum. That would be an impressive model, but beyond flagship range. If motorized, I expect a 42070-style motor-gearbox combo where a pair of motors can be toggled between 'drive' mode and 'loading' mode. I agree a big excavator would be a dream model. The new pneumatic switches mean the switches do not need to be near the outside of the model, but if they go for RC pneumatics I expect new parts. I wonder how HoG could work on a tracked machine, but having motorized drive on a pneumatic machine seems like a high feature level.

And/or another small car in 1H 2020. Could be a licensed series in that case.

The smaller 2-level transporter makes more sense to me than the flatbed trailer. It might include a car, but it is also possible for a matching car to be sold as a separate model.

Could be a scale match for the Mack then?

There seems to be quite some room between the battery pack and the motors too. Would it be possible to mount the IR receiver backwards, so the lower part (with the plugs) fits between them? This would also significantly reduce the amount of visible wiring. It would also however require some extra parts because the only pinholes are on the 'high' end, and it might reduce IR receipt from the front.

Possible explanation for the rear: Could this originally have been a power up design? If that is the case the IR receiver was likely a late addition.

powerup uses bluetooth, but it's not in technic yet.

Maybe you could drive the turntable instead of the central axis? Driving both in sync would be tricky from a gearing ratio perspective, because the 56 teeth on the turntable is a multiple of 7 you'd need a different source for a factor 7 on the inner axle. Maybe the small 28-tooth turntable?

42089, 42090, 42091, and 42092 building instructions (A and B models) appear to be up as well.

You could replace the u-joint closest to the wheel by using the half-joint which snaps into the hub. That feels stronger, though I'm unsure whether it is. On the inner side, you could make the bevel gear housing tilt with the suspension? Though that would probably be tricky in other ways.

Very nice MOC. Shows how interesting a model can be with even a single function.

Are these the same larger track wheels as on the stunt racer (but in a different colour)?

Is this even the same arch piece we're familiar with? The one I've got fits an 11 hole beam between the two pinholes at the top. The photo is hard to estimate but I'm pretty sure it's 9. If this is a smaller piece it may well also be shaped to allow stickering.

Basically, I just replaced the 12/24 and 16/20 gearing (2:5 ratio) with a direct 12/20 gearing (3:5 ratio). This works fine in both manual and automatic operation. I also did a number of adjustments to the wire runs. Top of boom: Rear of boom, note the extra small wheel to get the winch wire to run (mostly) free: For propulsion, I eliminated the two large wheels and replaced them by small ones in the legs, but I'm still doubtful whether this works: Overview shot. I tried to work the stickered parts in as nicely as I could, and think I did pretty well. Some functions work better than others: Boom elevation, in either direction, causes parts of the gearbox to work themselves loose. The winch sometimes runs into a hump and needs to be nudged along; that's probably due to how I tied the rope. Rotation worked pretty well until the two-and-a-half loops worked themselves into a knot; a solution with multiple pulley wheels (like on the other end) may work more reliably. The knot causes problems in some places, mostly all the way at the top where it won't go over the pulley. Propulsion just doesn't. Rotation and open/close work fine. I'll let my thoughts run on a better gearbox solution. Probably non-C-model by adding two extra clutch gears. Or possibly I'll just give up, shove in 6 motors and 2 sbricks, and call it a day.

Decided to try this build based on the uploaded LDD, and going pretty well so far. I still need to do the switching section, engine section, and outer body. I did note a couple of things which I'll probably adjust: The 12/24 or 16/20 meshing problem you mention is present in the driveline for the superstructure rotation, and causes noticeable friction. I replaced it with a single 12/20 mesh in my build for now, which runs much better. Unless I made building mistakes, in a number of places multiple pulleys with cross holes which rotate at different speeds or even in different directions are on the same axle. I'm worried this will cause friction problems, though I haven't tested this properly yet since I need to go out and buy some wire. I'm also not sure if this would be fixable within the C model limitation, as I'm not really tracking that. All in all a very impressive design, and my thanks for the freely available LDD.

Doesn't Buwizz have a configurable output voltage?

I don't think a separate receiver makes sense. Though to facilitate one motor powering multiple functions, I could see them adding switches/buttons on the HUB so you don't need to connect a phone/controller for that usecase. JopieK's teardown actually mentions the main chip for the train BB is the same as in boost. So chances are they're going to use that for technic too, but at the same time since it's in boost it must support 4 channels.

I don't want to judge before I've at least seen a technic model with it. They're quite unlikely to use this hub in a technic model since it's studs-only without pinholes. I do think though they're going to need a good set to sell the new system on.

If it doesn't bend it breaks, which is even scarier.

You could design stop-less pins with a matching tool to pull them out.

I don't think you can put the new pneumatic cylinders back-to-back the way you can the old ones from the studded era. However with the amount of extra reach the new cylinders get you using the old ones for back-to-back action may not be worth it.

If you add a motor down there, you need a battery box as well.

For short wires, there are extension cords you can order.

That's pretty much what I've been suspecting at least for the Volvo and similar. I doubt a Volvo-branded excavator is going to get TLG significantly more box sales than an unbranded excavator at the same price point, but it's an interesting marketing proposition for Volvo. I'm unsure if it works out the same for the supercars though.
