    I know it can be frustrating to not get something to work, but I'm afraid I can only really help if I could study the entire model. Apparently there is some serious friction going on which causes all kinds of issues, for example the slipping gears you are showing. Do you have a 3D file of your model? Btw, I agree with @emielroumen that it would be better to keep this all in one thread.

    You mean China?

    I noticed that too. I wonder how open the differential is by default, also if it's not Torsen. If the bevel gears inside suffer from as much friction as the new portal hubs do, then the diff won't be really open by default. That would also make this new differential pretty useless in non-RC builds, just like the new portal hubs.

    It would improve things for sure. It's good practice to support axles with gears at both ends, but if one of those supports can easily get displaced, that support becomes fairly pointless. So improving the support you mention is a good idea. Whether the rest of the structure is rigid enough remains to be seen.

    In this photo you see how much the structure deforms. I would fix that first. Try to incorporate a coherent main structure.

    @SNIPE, you're quite right. Your suggestions the other day felt like shooting with blanks, but it was probably my own mood that was bothering me. So, I'm sorry for my harsh reply. It's a great thing so many, including you, have contributed to the pimped up version and it's awesome that @jb70 has taken the task of compiling them into freely available instructions.
  7. Didumos69
    You are right of course. Also, if there would have been a RC 3-speed gearbox, it would have been depicted on the box. So I'm in the new differential camp again.
  8. Didumos69
    I don't think the red gear is a clutch gear. I also no longer think the red gear assembly is a differential. I think it's a 3-speed RC gearbox. That would explain the 3 speeds in the control+ screenshot, it would explain the price and it would make it top-gear-collaboration worthy.

    Thanks for your kind words @PetSild! I'm happy you enjoyed the build!

    So true. I hope so too. However, if the two thin gears you are speaking of have friction, like the gears in the new portal hub, then this differential is pretty useless in a manual build, just like the new portal hubs. For RC it would be awesome though. The only disadvantage for RC is that in a 5*7 frame this differential will need to mash with a 12t thick gear. That will give a 12:28 gear reduction, which is more than the 20:28 we are used to now. This is not always convenient. Then again, it does fit my believe that it's good practice to have a high speed / low torque drive train, in particularl when a gearbox is included. Together with the new portal hubs it seems LEGO is adding RC-specific parts to it's palet. I am curious if that development will continue.

    I think that is the case. The diff house seems to be inserted into the gear, so if they were to be assembled, the house would attach with half pins, not full pins, into the gear. Or there would be pins sticking out the gear, but that would be odd too.

    If you think motorization would fit the pimped up version, you don't get it. This mod is all about getting stock features to work as one would expect and to add extra features on top. Motorization would make this a completely different model. Also, others have done that. Please stop shouting out wishes that are completely out of context. If you want a motorized Bugatti or a 8-speed gearbox, try building one yourself.
  13. Didumos69
    Indeed, and with a gear at only one side it is not very useful in a gearbox.
  14. Didumos69
    That would be awesome. I doubt it will be a Torsen differential, because if it would suffer from the slightest friction, like the new portal hubs, it would not be an open differential by default.
  15. Didumos69
    Thanks you very much!
  16. Didumos69
    I was hoping for this! I really don't get why LEGO still cannot make a properly designed drivetrain. They should look more at fora like this and learn.

    We should start an open video republishing platform where you can post (embed) a YouTube video and where people can leave their comments and likes. The platform is organized in terms of communities to which people can subscribe and it has its own open (publicly available) algorithm to suggest content. Posting a video is always done in a community, so the target audience is always clear. All posts are public.

    Just read the whole thread. Now what should I do, target kids or not? I do not intend to make money with my channel.
  19. Didumos69
    Good point, I will keep it. Replacing the diff gives (28/20) x (12/20) = 0.84. 5 x 0.84 = 4.2. I mistakenly wrote 4:2, where I meant 4.2:1
  20. Didumos69
    Working with a 2 or 4 stud space is 'odd' anyway, I would say. Extend the distance between the motors by one stud, also between the shocks, use 4L axles and full 20t gears, which sit more solidly too.
  21. Didumos69
    I did think of that yes. I could just skip the 12t on the side and have the 20t go in the center frame directly. I have also thought about skipping the diffs and using the 12t from the side for a 12:20 reduction instead of the 20:28 the diffs give. That would drop your 5:1 ratio further down to 4.2:1. Problem is that I have little time to build right now. Will take some time before I can try some things in real life. What he said.
  22. Didumos69
    I meant with XL motors and Control+.
  23. Didumos69
    Well, to be a bit more nuanced, this started with a wish / dream I had about a fairly simple model that would have a spark of this: Soft suspension and speed. So that's what I aim for. The front suspension has 8l long suspension arms, which gives a very nice soft feel. I still need to redesign the rear axles to get the same feel there. And then much will depend on the speed it can develop. It doesn't really need to be off-road capable, just this tilting in turns, is what would make me smile. But sofar it's just a 3D idea. I have not seen anyone build anything speedy with the new hubs, so maybe it's just wishful thinking. But somehow I have the feeling that 2 of those new XL motors should be more capable than what we've seen sofar.
  24. Didumos69
    That there is a big chance this will fail.
  25. Didumos69
    I certainly will. Gearing would be better yes, but I don't see a way to work my way around the big turntables with the few liftarms I have left. They are practically 9 studs wide.
