    Thanks for the info! Yes, I know that that's the super bad part, I had experience with that, and then went back to an old version! For me it did not work even for 3 test parts, 2 liftarms and a pin, I was trying to rotate one liftarm on the other but could not get it work. Somebody reported the issue months ago, and don't know if anything has been fixed, on the forum I can't even find the issue now.. That's good to know, I did suspect something like that because even though I did not update, I seem to have some recent parts!

    Does the latest version of Studio have the new 87mm tires? I don't want to update it because the latest version screws up many things.. Does anybody have the tire part file? I could not find it on @Philo's page yet.

    Nice contest, there are many nice and for me unexpected entries. One thing is for sure, it nicely showcases (in my opinion) real technic spirit; many interesting but fairly small entries packed with functions! Nothing big for the sake of being big :) I think that would neatly solve the problem of down-voting others by abstaining from voting, but would not prevent people from literally down-voting other very promising entries by ordering them last, which could be another way to implement the same strategy. So not perfect solution. But let's suppose people here would not really do that.. :) Actually, I still think the voting scheme of optionally giving +1 / +2 / +3 for each entry excluding your own (without any further restrictions on total points) would be more sound. As usual, I found about 6-7 really interesting entries, and had difficulty ordering the rest (even ordering the interesting ones is somewhat arbitrary after the first 3). I believe the simpler the system the less potential for even unwantedly abusing it. For example, with such a system, there would be no way for putting other entries into a disadvantage, I guess.

    The problem in the first place, I bet, was that he played with it!! That's what left its marks..

    Indeed this has quite a few interesting bits and mechanisms, I even thought about buying one until I saw the price.. I guess I’ll just shop for some parts then..

    The general shape of the Hummer H1 is very recognisable in this model, great work on the shaping even with a restricted part selection, I like all the square shaping! The tires are a good fit, even the rims look nice on it :) Just out of curiosity, can you show the custom CV joint that you built?

    Talking about the model itself :) Very nice one, I like the clean and simple design of the chassis, the modularity of the body, the realistic steering, gearbox and that it has leaf spring suspension! Nice trick that you used and extra linkage to center the steering link to avoid collision with the leaf spring! I have been experimenting with this kind of suspension as well (just preparing my model for publishing), and came up with a leaf spring geometry that's different to yours I believe. Can you show more images of the suspension itself without the wheels? Unfortunately, when building a model on the same scale as others have built before, it is unavoidable to become similar; lego panels are not that varied that there would be many ways to build the same thing. In this case I could imagine both ways, either @paave being influenced by @rm8's model or him arriving at a very similar result (but different in its nuanced details) on his own (though I guess having seen others' models beforehand, it is hard not to be influenced). Anyways, in such cases I do make sure to give credits to the ones before me even if I could have come up with it on my own. And I understand @rm8 too, when I see a model that could be influenced by one of mine, I do like to get credit as well.

    So does that programmability only apply to the app control and not with the physical controller? Maybe just that physical controller on the picture made that association in me..
  9. gyenesvi
    You mean the physical remote? How is it possible to program that?

    That's a serious machine for a competition of vehicles on small wheels..

    I like the smooth clean lines on this one, and the door mechanism also seems quite nice! Great job!

    I did watch the video, but did not catch the moment when you switch at first, but indeed it is visible. It does seem to slow down a bit, but keeps rolling. One useful thing to have is a phone mount for the gamepad. I sometimes use that for filming while driving, and can follow my model that way :) The only problem is you need another phone to actually control the model, because both the control app and the camera app needs to be in the foreground.. :(

    It's a relatively recent development in the BW firmware (both 2.0 and 3.0 units) to solve BW unit shutdown problems. When driving 2x Buwizz motors from a single BW unit, the two motors may take up around 5A together when doing quick forward-backward switches or when climbing steep hills with larger, heavier models. To prevent this, BW introduced current limits in the firmware, which can be set for each port. Setting the current limits to 2A for the PF ports on a BW unit can effectively prevent this shutdown while being unnoticeable for the top speed of motors, because on even moderate surfaces without quick direction switches the motors typically draw less than 2A. The only problem is that the BW firmware sets the default to 3A for each port.. Hence, in the BC2 app, it's not taking any useful effect. Resetting the limits to 2A on startup would already be a useful start. Furthermore, having a configurable current limit for each port would take this one step further, but that would take a bit more change in the app I guess (needs new UI elements).
  14. gyenesvi
    Hi @imurvai, do you still make smaller changes to the BC2 app? For controlling Buwizz units, it desperately needs current limits, at least a default value of around 2A to stop the unit from shutting down. The BW app proves that current limits work quite okay to prevent this, but it would be great to have it in BC2 as well. Would that be doable?

    This turned out really nice! I also thought about building an AWD car with live axle suspension at this scale, but hadn't gotten the time for it yet. I like your implementation, the torsion bar is a good idea here and it's nicely done, I like how the upper link acts as the spring mechanism as well, and the way the torsion bar is fixed at an angle. The bodywork also came out cool!

    Of course, but RC cars can get away with it because they can just easily change gears while stopped. And indeed, I never thought it's a good idea to change gears while running a heavier model. That's a very nice case study of the effect of weight on the change smoothness, and indeed, you have me convinced with this. One thing I'm curious about is whether the car keeps rolling when you switch gears while driving?
  17. gyenesvi
    All of these, exactly my thoughts :) Nice one! Only a bit too fast for us regular alt model builders out there...
  18. gyenesvi
    That's a nice mechanism packaged in a neat body! I like the placement of the Buwizz motor, I always wondered whether such a placement is possible, looks cool and even somewhat realistic. Too bad it's only possible for RWD. The clutch system is interesting, though wonder if it's necessary. I have seen people change gears without clutch under the load of 2x Buwizz motors, so it seems the gearbox parts can take it. But for the challenge of making this clutch mechanism I completely understand why you went this way.

    That is some badass trial truck in a large scale! Very well made, I like the simplicity of the hardcore functionality and it also looks great, especially with those RC tires (I can see many people are using them in the trial race as well, and I understand why, very good ones). And I like those portal axles and that front axle steering with that huge gear :) The competition sounds like a great fun, great looking builds all over the place, so many huge and powerful trucks!
  20. gyenesvi
    That was my guess, but then using the yellow diff could solve that problem, no? That's only about 10% faster than the current solution, which could even be beneficial for engine speed.

    Sets 42099 and 42129 don't have portal hubs. They have planetary hubs, quite different, but Unimogs have portal hubs. You mean there's a specific reason? (I guess not just that you could not build it or did not have the parts). I'm curious what it is. Do all Unimogs have portal axles, or only some specific types? Maybe this specific one does not have portals in reality? That's a different build from a different person of a different Unimog :)
  22. gyenesvi
    Great looking model and nice functionality! Where is that exactly? I cannot find it, neither in the description nor in the video.
  23. gyenesvi
    True that they stack tighter, but I have good eyes :) I think fragmentation is worse / more visible when lines that break the surface go in all directions and positions; it's less noticeable when they line up nicely. But thin liftarms usually introduce extra fragmentation lines that don't line up with the surrounding full beams. That said, yeah, having 6L thin liftarms is better than nothing, but they exist in much fewer colors than regular beams.
  24. gyenesvi
    You could, but.. For one, it's more flimsy, especially when used structurally and connected by friction pins or axles. Second, it looks worse; and when things already look fragmented enough even when full beams are stacked, then making it look even worse is not something we're looking for.. Remember the motto of Lego: Only the best is good enough.. So why make it worse when it could simply be alleviated with parts that would be super useful in many areas?

    Can you share why the rear diff needs to be on a half stud offset? Why is it not possible to use red diffs with 12:28 gearing on both axles, centered? There seems to be enough space inside the rear axle frame for the locking ring even if the diff would be centered, no?
