On display I have two Star Wars sets, two Speed Champions sets, the Airbus helicopter, and the CADA Ferrari 488. I don't leave any of my MOCs built, so I guess it's 100% A-models for me.

High: Released my modular Toyota Land Cruiser 70 project--My first Technic MOC with instructions! It was a big learning experience, and really complex figuring out how to make good documentation for such a modular setup. I'm really pleased with the result! Low: Built almost no Lego since the spring. The summer was spent working and hanging out with family, with a bit of 3D printer work thrown in, while the fall (and winter so far) have mostly been spent building another 3D printer. I'm afraid I"m moving on to other hobbies, but I think those fears are unfounded. I've enjoyed the little Technic building I have done lately, and the 3D printer projects are winding up, so hopefully after my Christmas break I can get back to the Technic! 2026: Hopefully finish my Mini Excavator MOC, and get some momentum going again for the Technic hobby! My class schedule for next semester will give me ~13 extra free hours per week, so more hobby time!

Nicely thought out as usual! That is an interesting trick for the front axle

That looks very neat and functional; nice!

It has been a LONG time since I had an update on this project, and it's gone for months at a time without progress, but I do have some more to share now. So, one of the first problems was figuring out how I'm going to route four functions through the arm, without making it absolutely massive. Universal joints seem like the perfect compact solution to it, but the issue is that they can only rotate about 45° upwards before starting to lock up. However, I couldn't think of anything better, so I ended up going with four parallel doubled U-joints, allowing for about 90° upward motion! Finding a pivot point for the arm that aligned with the virtual pivot of the U-joints was fairly hard, and required half-stud offsets in two dimensions, but it seems to work well I then spent a while building up the area above the turntable, which was pretty challenging. I essentially needed to route 8 separate axles (the four from the arm, both track drives, turntable rotation, and blade actuation) from existing locations to reasonable locations with longitudinal axles, for the gearbox. Also note the work on the mechanism for activating blade motion through the turntable (described further in previous updates). I've now got a worm gear mechanism rotating an arm that pushes down on the LBG 2L axle extender on the 2L transmission driving ring in this picture: The TDR is only really being used to create a 16T gear that can have a sliding axle go through it, like those red 8T gears. As mentioned before, that axle is being used both for driving one track, but also for pushing the blade down through axial motion. After that I moved on to the gearbox, which is really complex! It's a 3-input, 9-output distribution gearbox, with six driving rings involved. These are split into three sets of two rings, with three functions from each set. Interestingly, there's only two wave selectors being used, which are geared together for synchronized motion. In order to keep it compact, two selectors are actually driving the same ring from opposite sides, just because those are the locations they needed to be placed in! I'm still busy with other hobbies, and will probably not be near my Lego over my Christmas break, so I don't know when the next update will come, but I think most of the most complex parts have been finished now! I guess the next issue will be figuring out where to install motors, and then working on installing the arm

Hooray! When I saw the set was using those screws, I hoped for a Technic-compatible nut! That's great, and should make using those parts a lot more convenient

I can't say I mind. 1:10 offers more room for functions, obviously, but if Lego isn't going to put more functions in anyways, they might as well keep the scale and price down with 1:12

Nicely detailed! Thanks for doing a detailed writeup, as well. I also appreciate the effort put into the rear suspension! I do hope you manage to get some stickers done at some point

Oh, very clever! Thanks for sharing these little details

That is a seriously clean-looking model; nice work! That's a real shame about the new LEDs! That was a super important feature!

That's a cool solution!

Maybe part of it is to make the venue work? If you've got locked diffs, maybe your capability level goes up to the point that it would be trivial to make it through the course they have built, and building a harder course is logistically difficult?

Cool! I'm glad to see the progress!

Nice work! That suspension design is really interesting. Do I understand correctly that there are no springs involved, and it just relies on the weight of the axle to cause it to articulate down?

Realistically it should have AWD, but I doubt Lego will attempt it. I think it would either require new parts or unconventional (and probably sketchy) techniques to do it at this scale. That being said, have they modeled any other real-world AWD cars at this scale before? If they've been consciously avoiding it until now, it would be more interesting that they decided to go for one now

Looks pretty decent! Glad to see them choosing a well-known and recognizable car this time

Nice, that is compact! It's always satisfying to use double-bevel gears in both perpendicular and parallel meshes at the same time

I was pretty impressed with the performance of my design! Torque wasn't enormous, but it was enough to drive a large car reliably, with planetary reduction afterwards. Oh, I hadn't realized that you're driving the disc from both sides! That's cool, and should improve grip over my design. I had to use a 2-stud wide tire, which produced a speed differential over the different parts of the tire, causing wear. Sounds like a cool GBC project!

Nice, I love to see cool mechanisms like that being developed! I did a similar build years ago, but I was trying to get it compact enough to squeeze into a car model, so it was built a bit differently. Yours should have a much larger spread of ratios than mine did! I do think this style of CVT is probably the most practical one for Technic. Is there a larger project this is going in? That cone looks pretty specific

I gotta say I like it! Not enough to buy it (haven't bought any of the cars in this series), but I like it. It's such a classic car, and I think the color scheme pulls off the look well. There's just something about classic race cars with the really meaty tires on them! I can't say I mind the choice of rim either. The other one people are suggesting would look better (if they made the skinny one for the front), but I think the truck rims here work way better here than they do on any of the modern cars they've made in this series. I guess the new rear tire is a plus? That diameter of truck tread tire has been used for cars an awful lot at this point, so I guess a better tread for them is nice? Also, I haven't seen any discussion of the parts on the A-pillars. Those are new, right? Something like 1x5, with a 1 stud offset?

Wow, that's cool! Sounds like just what some of those high-speed 1:8 models need!

The alternate models just don't stop! Nice work

Thanks for sharing!

I've tried printing TPU tires, and while they were soft enough, they weren't grippy at all. You could flex them, but they wouldn't stick

That's some MOC inspiration there! I've done FWD transverse engine cars with motorized sequential transmissions, but I don't think I've ever done one with a manual shifter. It'd be some interesting linkage work to get that to work with a transverse transmission
