Maybe the PU XL motor is also getting a CE symbol, hence new ID and old one retiring. Anyway back to the set, I think the counterweights increase the price a lot, especially if you take in account that price per gram is more reflective of true value.

It just so happens that the small female CV axle fits directly into the planetary hub, though with a very sligh offset :)

My tips: Since I see you need A LOT of torque, I would recommens combining planetary and portal hubs, or just use the planetary ones, they are much more compact, stronger and there are no axles to bend on the way to the wheels. Secondly use a 7x11 frame with 28 gears, those are currently the strongest perependicular drivelines available (with exception of maybe yellow diff). Third, split the driveline to left and right sides, so that you split the torque more evenly between 2 seperate systems. FYI, just recently I made a project with 16 BW drive motors which produces way over 1500 Ncm of torque, so you can do A LOT if you know how to spread the load over multiple components.

It doesn't look like a meter tall, but doing a quick calculation by counting the 16L link segments, it does indeed seem to be... But with all the talk about structural and stability issues... I thought it would be taller. Or it used to be and now it was reduced in size to the current size? Anyway besides the rectangular frame pieces and counterweights I don't spot any new bricks. There are a lot of large single pieces which let's say use a lot of plastic... But still seems very expensive. Unless they the weight of the counterweights is the same price as the weight of expensive electronics... Talk about electronics, I see one hub and 3 motors (1x winch, 1x main boom tilt, 1x secondary boom tilt), so there should be another hub powering 3 more motors somewhere in the lower structure (2x tracks + 1x slew). Still think the Liebherr Excavator was a better deal, but let's see what the actual reviews will show, I hope if not anything it can at least lift some weight. EDIT: There seem to be 2 types of recantuglar frames, a thinner type is used for upper and lower side of the booms while the larger version is used at the sides.

Just wanted to say that I think this year has been one of the best ones, if not THE best one for new parts. To summarize just how many awesome new parts we got: Aesthetical: Very small panels (2387. 2389) Very small curved panels (2395, 2403) Small angled panel (2457) Quarter elipse panels (2442, 2438) 11x2x5 curved and straight mudguards (2509, 3538) New small, arched mudguard (2459) New 81,5 x 23 tyres (?) Structural: 1x7 flip flop beam (2391) 3x5 flip flop beam (2477) Pin connector perpendicular with (only) 2 pins (2393) 7x16 trapezoid frame (79768) Large rectangular support frame (?) Small rectangular support frame (?) Mechanical: 5 stud CV axle (2405) Short CV axle (?) New ungeared hub (?) Counterweights (?) I think this is the highest amount of new parts I've seen in a single year. And If we add the parts added in the back of the last year such as the new differential, straight gears and shock absorbers, we can really see that TLG has been investing heavily into this theme as of lately. IMO we are currently living in the golden age of Technic.

Found a review: https://www.brickfanatics.com/lego-42161-lamborghini-huracan-tecnica-review?noamp=mobile From what I see from this review, I have to agree, the steering is very sloppy and has a lot of slack, the worst one by far. Color issues are same if not worse as Lambo, it's BEEN 3 YEARS, is LEGO still overcooking those parts (22961, 15100 and such connectors which are made from a differnt, softer type of plastic) during production? And just general shaping is not as accurate as other cars at such scale even with the new micro panels. I suspect because the original reference is just not the best suitable for such small scale and curvy, organic shapes. If the Senna and Bolide were a hit, than this is sadly more of a miss IMO... BUT to end on a positive note, it is a good lime parts pack, having more panels and wheel arches in other colors is always a good thing for MOC-ing.

I asked myself the same question, since the new ones actually allow the gear rack to steer like a few mm more. I think this a reflection of the design development duration, at the time the set was designed, there was no straight 12 tooth gear available? Or they used the bevel ones on purpose to limt the steering angle? Or to reduce color vomit? This specific issue is very common in current sets, some use the old bevel gear, some the straight one...

Yes, after all these years we have a complete reinforced driveline starting from the differentials, CV joints and now the hubs. I kindly ask the Technic design team to use them as much as possible, everywhere, even though they might be harder and more expensive to manufacture (since they have to be lubricated and ultrasonically welded together).

I'm so happy that I was right about the hubs and the new, shorter CV axle. Also really, really happy that the new hubs come preassembled and prelubiracated with lower slack.This opens a whole new world for my high performance personal and professional projects.

I have the feeling that the same people behind Pybricks are also the FW developers, so it doesn't surprise me that the app is developed externally too. Sounds like a lot of communication between different parites with LEGO probably being in the middle...

Siike medium one is used for testing, so it should work. I can also confirm the Mindstorms one works in one of my models. Try recalibrating, or reimporting the profile.

Make sure it's not actually the motors overloading and triggering their thermal protection.

Yes, the inner dark bluish gray part pops out. I have built lots of supercars using this part and at least at 1:10 scale I never had an issue...until now, that is why I suspect material change. Ideally the new hub would be attached in a simillar way as the small turntable using several independent latches and have same kind of a good fit.

Coild be a bad contact. I suggest taking a needle and pulling out the 6 contacts at affected ports a bit.

I hope the new hubs are also fixed more secure... Was driving the motorized Peugeot 9x8 mod and literally almost all the normal, current hubs failed and came apart. I think this has to do with the new redesign of the hubs which uses softer material...

With the introduction of Daytona's bigger wheels an updated hub brake disc with a larger diameter would be welcome...

No reduction, the only gearing is 14:22 from L motor to differential. I have a feeling the new hub will slowly replace the old, current ungeared one, since it has a stronger mounting points (towballs are part of the hub), higher steering angle (some 40°) and can carry much higher torque. I only wish they would actually have used 6 pins to attach the wheel instead of just 3, it would make the wheels almost impossible to fall off.

Found another photo of the set, showing the new hubs more in detail: So the new hub seems to be almost identical to the current ungeared one when it comes to attachment points, the only difference is that towball pins are fixed and that it can accept the new, stronger CV joint. I'm gonna keep digging for more details about the inboard CV joints.

I was browsing my phone files and found that the Lego Builder App actually saves the brick geometry files on the phone: \Android\data\com.lego.legobuildinginstructions\files\UnityCache\Shared Now I have no clue if this might be useful or not, so I'm asking someone with more experience in this area... Anything useful we could re-use, import in LDD or such? Thanks

Depends on the rubber band types. The colorful, silicone ones with rounded edges hold up really well, while the black, rectangular ones seem to be from a different, more brittle material.

Now imagine how the designer's hands must feel like, having to build tens of prototypes

So that's where all the Osprey panels went to... Though building these macro elements and using turntables to pop them together is a really innovative idea IMHO.

How about this timing, we just updated the API today: https://buwizz.com/BuWizz_3.0_API_3.22_web.pdf

Here's the updated API for the developers in the preparation for next, stable release. https://buwizz.com/BuWizz_3.0_API_3.22_web.pdf

Exactly, they push/pull on the system a bit but utimately cancel each other out. I did a bit of quick LDD sketching up and the front wheels are driven directly by an L motor. Steering is driven by an L motor on top of the FWD drive motor via a pair of 16 tooth gears. The rear wheels are driven by an L motor via 3 16-tooth gears. All diffs are the Daytona ones. The front suspension seems to be able to swing independently.
