Timewhatistime

"Weird and interesting" - these are the right words to describe this nice MOC. The combination of old and new parts is great, and by the somewhat rare 3x7 bent liftarms in trans-red one can deduce your "active" time in Technic.

Maybe the single motor isn't strong enough to drive more than one function simultaneously? So the setup with a single lever avoids this issue. But I consent, a multi-function setup like in 42042 would be more fun to play. I can imagine that there will be some early MODs which will provide exactly this setup.

The very small panels (#7 and #8) are new in trans-red. Nice!

Great work, @R0Sch!

You are right, there are white 3x3 T-shaped beams - attached to some black beams (visible in the view directly from the top). The "extra parts": There are two 3L lbg beams at the front axle (at the same width as the white 3x3 beams). I'm not sure whether white and lbg beams are connected by black 5L beams on each side... there has to be some space for the two black 4L thin beams which hold (and tilt) the grabber.

Does anyone have a clue about the two white liftarms providing the little grabber vehicle's base? The standard 3x5 L-shaped liftarm doesn't seem to do the job, does it? Speaking of this grabber vehicle: It looks like a fun mechanism and can even be tilted (by the well-known combination worm gear + 8 t gear).

Yes, you are completely right. My fault! Thanks for your correction. This mechanism is called "Z-kinematic" (at least in German).

The bucket will tilt in the degree the arm is lifted; there will be no compensation in this movement because all the mini-LAs are located on the same axis.

On some of the image the yellow maccaroni parts (front axle) are atttached to the main chassis (below the cabin), on others they are torn half way out, so that a red axle connector is visible. In effect, the 5x7 frame (around the front differential) is misaligned (tilted downwards in respect to the rest of the chassis). TLG should have engaged some pros for taking the photos... or at least to assemble the set...

This connection is quite creative and new. In principle, I like it. However, the crane's load will rest on just two half beams (i.e. the black 87408 connector). Moreover, the second stage of the boom is held in place by a single 4L axle with stop (going through the connector). Considering the massive first stage of the boom, this solution seems to be odd and lacking stability.

TLG still doesn't learn and ranks symmetry higher than accuracy. The arm will be (slightly) twisted when being raised. It's the well-known issue with the 20t bevel idle gears getting turned counterwise...

If this is the design of a lunar outpost, I prefer staying on earth.

The quarter ellipse (probably 2x7) in dbg in the bonnet is a new part, isn't it?

The mini-LA's design has been slightly updated.

In the promo image, the left mini-LA doesn't seem to be connected to the boom (the ridges of the mini-LA pinholes are visible)... whereas the box shows a black 2L pin.

Now I see. Thanks for your clarification. Your steering mode mechanism in the mini 42054 (and now in this Xerion) is ingenious. I spent some time to study and create such mechanisms (and still have one to build, based on a completely different principle), but I never had the idea to do it the way you did. Well done, @Ngoc Nguyen!

The images seem to show different steering angle for the front axle and the rear axle. Are they really different?

Hm, I cannot believe that there is a 4-4 angled beam in this 65-parts-TLG-flagship of the year 2025. If it were, the red perpendicular connector could not point exactly upwards because its axle hole were connected to the beam's axle hole via a black 2L axle (or a black 3L axle pin) - set aside the geometrical issue shown in your digital image. I'd propose another black quarter ellipse (2x3 or maybe 2x5).

Six parts lying on a table are a very good start. Thanks for sharing.

Please, would you be so kind to build proper sentences and use punctuation like everybody else does in this forum? Thanks a lot!

The main point of this thread seemed to be to ensure that the author is the first one to provide their "information" and to get clicks from over-curious forum members (like I was). I will learn from this and avoid reading threads with boasting headlines and annoying typos.

It is included due to its low weight.

This isn't a particularly precise description of the issue, so every answer will be based on heavy (and maybe false) presumptions. Once again: I presume there is a severe misconception about the old 4L differentials - they are cog wheels whereas the newer differentials are bevel gears. Only the latter ones cause the drivetrain to stuck when they aren't orientated correctly. Images of the bottom and the interior of 8466 can be found online.

http://technicopedia.com/8466.html 8466 uses the old style differentials (4 L), so their orientation does not cause the issues (if it is possible to turn them at all). So the issues have other causes. Probably, it is a good idea to consult the building instruction or to look close where there could be a mistake in the orientation of a pair of gears.
