Could 3.7V simply be the charging voltage? For example, if the battery is split in 3 banks which are in parallel during charging but in series during use, that would allow the unit to be charged using a standard 5V USB connector, and still power motors at 11.1V.

How about the standard full bush? EDIT: An axle extender should also work. And if TLG made 2l bars you could use one to keep alignment.

Those curves should at least be relatively easy to replicate with technic.

I just built this, and am going to have to partially disassemble it to ensure midwinter is in late December instead of early February.

I'll put up 42128 as a recent winner. While the liebherrs are interesting sets to a degree, there's too much big for the sake of big in them.

Also consider the small but persistent voice from the convention grounds, particularly GBC builders, for a power supply which can keep going for 12 hours nonstop.

Hard to say without knowing the question. One equation with two unknowns so the solution set is not finite. Expressing y as a function of x, #5 is quadratic in y² so that's relatively straightforward but #4 is a cubic, so that'll get difficult.

I don't think that'd make a good set. It's huge and there's not a lot of functions going on. Automatic leveling might be interesting? As for the real thing, anything human sized would scale down smaller than a stud. I own Janotechnic's crawler. That thing weighs in near 8k pieces without the rocket and it's microfig scale.

Steering through gearbox?

Based on the significantly higher set number for the recolor, I'd guess it was added to the lineup rather late. Probably after the 2025 numbers were assigned to sets?

Looks like it has rounded inner edges.

If there are multiple track sections, I presume that turntable is not going to connect to a freely rotating superstructure. Does the drive need to go through the turntable at all?

I just don't see RC pneumatics happening because of the absolute positioning problem. You'd have to go hydraulic to fix that, which I likewise don't see them ever doing.

Extension rings are a thing and you don't need to do it all off one switching drum. I'd say getting all functions into the back hoe arm is a bigger barrier, particularly if you are implementing side shift.

In C+/LA solutions, consider that while the CAT has a 4-function gearbox the new Yamaha gearbox parts allow for an 8-function one.
