What do you call a machine that works both like a tractor and like a truck? A trucktor

Well last year we did get a surprise set, which is the 42127. No one knew it exists until official photos popped up in late November.

Those in my 42000 also yellows and their stickers peeled off twice.

I gave the thing a nose job.

So this is my vow. All white parts will die.

Funny how I see 5 vids with that face out of the last 15 vids of this guy, which doesn't sound like "a small minority." But anyhow let's get back to the topic. I took a look at the real 42140 that I have today, and I felt that the neon yellow looks actually faded or washed out in real life. So I think I'll replace all the neon yellow in this set with regular yellow as well.

Put it on the shelf for 2+ years and the white parts will turn yellow anyway

This is a concept of putting the two 20z gears inside. A potential problem is that the 20z gear may collide with the driving ring on the left. I don't have a spare driving ring so I can't test. Can someone check?

I will after the instruction is released. I need the official instruction to make sure that I didnt build anything wrong or miss anything. At the moment something is wrong with my Studio model and I can't figure out why.

These are the two solutions using standard techniques: The one on the left uses 3 8z gears to invert the direction to the second row of clutch gears, while the right one use the toggle bracket with 3 12z half gears. I feel like even though these are possible, they aren't used in the official set, so there must be some reasons. Maybe the solution with 20z gears is more stable under pressure. I'm trying to find a way to use the 20z gears but inside the 11L liftarms instead of outside. Good to know. Thanks for sharing!

Another mod I'm working on is the removal of the blue bevel 20z gear. It can be seen from the outside, and its color interferes with the appearance of the helicopter. It can't be replaced with a bevel gear because the bevel gear collides with the slanting panel. The sole function of the two 20z gears is to ensure that the two 16z gears and their axes (highlighted) rotate the same direction. One solution is add a row of 3 8z gears between the two axles, like how the 42113 gearbox was done. I'm not sure how feasible is that solution because it is show to put stress on the gears in the 42113. I'm trying to figuring out other solutions.

The inappropriate face expression strikes again.

White parts age horribly. That was what I learned upon taking out the 42043, 42040, 42096 out for look the other day. The white stickers cracked and fell off partially, and the areas not covered by stickers turned yellow. The cabin parts in 42043 even got a new set of stickers a year ago, but they still degraded. "So this is my vow. All white parts will die." - Gorr the god butcher. I plan to replace the white parts in my existing models with parts of other colors. I'm also thinking about doing that for upcoming sets with white panels, like the BMW bike or the Airbus. The white panels is one of the reason I hesitate to get the BMW. To start off, I've isolated the white parts from the cabin of 42043 and put it here. https://rebrickable.com/mocs/MOC-117421/nguyengiangoc/42043-cabin-white-parts/#details I intend to swap all of that into either orange or DBG. Orange looks better and still fits the construction vibe, but some parts have to be replaced.

So this is my vow. All white parts will die.

No inappropriate facial expression this time? I'm surprised.

Steering is done through the steering wheel. A HOG can be added in the reconstructed version, but I don't know where to put it.

It still looks decent up to this point It's the front slope that ruins everything about its look.

I don't think it's possible at this scale. In terms of functions I think it will be like the Senna. Maybe I'll add a HOG steering.

This model is a set with the code SY8613 from Sembo. The red car is apparently based on a Ferrari 488 GTE, the same subject of 42125, or at least a racing Ferrari. To me, this model looks way way better than the official Lego set, because the front in this model looks more unified, while that of 42125 looks fragmented and lacerated due to the unnatural curves of panels #50 and #51. Therefore, ever since I saw this model, I've always wanted to reconstruct it with Lego pieces. The problem with models like this is that the instructions are not available as PDF. I did this kind of reconstruction once, and I gotta rely on a quick build clip of a reviewer. There is none of that for this model though. Fortunately, the other day I came across a listing for a used copy, so I immediately bought the instruction. I'll start the reconstruction in a few days, after I finish building the 42145 Airbus in Studio. According to the instruction, this set has a functional steering wheel, a differential, brick built fake engine with no drive train or moving parts, and compatibility with remote control upgrades, which include an M motor, a Servo motor, a type of bluetooth/infrared small battery box. This model has 1206 pieces, which is kinda hard to believe, given that the largest car of this scale, McLaren, only has 800+ pieces. A couple of changes will have to be made, of course. Because there's no custom sticker sheet, I think I'll substitute pieces of the same color in to see how it goes. Some places can use the 2x3 middle panel. I'll also try to put a working engine in. If you're concerned that this type of thread does not belong here on Eurobricks, I did a thread like this once back in 2020 and got the greenlight for it already. (Also shamelessly promoting it ) Stay tuned for more updates.

Without the engine cowling, the general shape actually looks decent and to scale.

This is probably another use of the new 20z spur gear. The bevel gear collides with the edge of the slanting panel.

Drivetrain of landing gears function Drivetrain of winch function Drivetrain of rotors in slow mode Common gear ratios are (20/16 x (8/24) x (12/20), then x (12/28) for main rotor and x (20/12) for tail rotor. Drivetrain for rotors in fast mode Common gear ratios are (20/16), then x (12/28) for main rotor and x (20/12) for tail rotor.

I'd say we grab 42128 while it's still cheap, while your lips are still red, and build a waste handler AND something else out of it.
