    Great, looking forward to it! What I was curious about is how the drive is transferred onto the axle, that's the interesting / unusual part, and the bottom image did not show that, but now I found the top image and I can see. I was wondering how you braced it. Unfortunately I am afraid that on challenging enough terrain if you push it hard that gear mesh between the 20T tan gear and the red differential gear will prove to be the weak link as it is not supported by a rigid piece on either sides immediately next to the gears and the axles may have enough space to bend (especially on the middle axle where the axle holding the tan gear does not go from side to side but is split in the middle). Maybe with 3 axles / 6 wheels and planetary hubs and open differentials it won't be a problem, it's hard to tell, that's why I'm curious about an actual ride on tough terrain. Would be nice to know if such a setup would be reliable on a truck trial :)

    It looks really cool! More details / images about the drivetrain and the suspension would be appreciated though. It drives nice on simple terrain, but I wonder how it behaves on more rugged one. Have you tried somewhere?

    Cool, it is getting recognizable :) The only part I find messy is around the front fender. Maybe, if the angling of the fender piece was not so aggressive, you could make its angle match the bottom of long wing panel above it and simplify that area a bit by removing the short panel? Curious about the performance, it seems huge!

    I also thought that, @Maaboo35 why do you think they are new?
  5. gyenesvi
    I don't think so, the brightened frontal image of rm8 suggests that the inboard CV joints are also the new ones, you can see the ridges on them. And the rear image above clearly shows that the axle width is indeed 17 (6 long arms starting at 7 stud width).
  6. gyenesvi
    I thought the same and started counting, but unfortunately I counted 9 at the first go. But now looking at the high-res brighter image, maybe it is indeed 7 studs only, so there is still hope! And it would make sense. At first announcement I thought this car would come with 75mm buggy tires and an axle width of 15 studs with regular old wheel hubs, and that the Ford GT's double-sided CV joint was made for this. But it clearly has new CV joints, and with those joints the narrowest axle possible is 19 studs, which is pretty wide for 81mm wheels. So a 17 studs wide axle would make sense. And that CV joint part would be a VERY useful one! Hmm, I think it might actually even be doable, as there might be space, but it would not be realistic if it was just connected to the drivetrain, as that's not its function in the real car, plus it would just decrease efficiency of the drivetrain.
  7. gyenesvi
    Definitely not possible if motors are not coupled for front/rear axle, as it seems. That makes sense.
  8. gyenesvi
    The high res images posted by rm8 clearly show 2 L motors in the front, one higher and one lower. The higher would be the steering motor I guess.. Why do you think there would be two motors in the rear, and where do you see them? Also, how would it be possible to route the drive to the front in that case?
  9. gyenesvi
    Really good idea for a B model, and nicely made, great color usage/consistency. Also, the motorized mechanisms are well chosen on for this!
  10. gyenesvi
    I like this :) New tires are great (would be a perfect replacement for the Zetros), hopefully new hubs are even better, and I think the yellow diffs were made for this one, to make it as fast as possible while keeping it solid! Nice parts pack altogether, black is always good, and we have lots of interesting panels here. Also, the 3L motor setup is nice, easy to build with and finally we will have a C+ profile and somewhat cheaper parts pack for that simple setup. Do you think the front/rear part of the drivetrain is coupled? I don't think so, as the hub would be in the way. But I guess that may even be realistic in this car. The interior does seem unfinished, based on the images there would even be some space for it above the hub. I am guessing that the battery is accessed from the bottom.

    Great looking model, and I like the suspension / drivetrain solution, especially the one with the new CV joints at the front, clever idea! I actually have some very similar RC tires I bought from RC4WD for building something like this :) Where did you get yours?
  12. gyenesvi
    That's interesting to know, thanks!
  13. gyenesvi
    Interesting, my 8880 has these in grey. It's the towball pins that are black in there. Are you sure it came from that set? Or maybe there were different version wrt packaging? Do you have the instruction booklet? In which color does it list those parts? I don't have access to mine right now, but I do have it somewhere..
  14. gyenesvi
    Well that is indeed a genius solution (love the steering as well)! Thanks for showing! However, it does not really fit my idea of clean and solid, neither is it long travel, and it does not have a diff either :) But for a small model like this, it's really nice.
  15. gyenesvi
    I agree with you for the case of fast vehicles (I guess that is why buggies like Ultra4s and UTVs have them), but I think for a slow trial truck the front live axle setup can be better because of the more ground clearance it provides. Also, another thing to consider is that IFS is only really useful if it is high travel, but that's something hard to achieve in lego on a smaller scale or in a narrow vehicle (like a truck) when it is driven, because the diff already forces the A-arms to be far apart and shorter (unless you drive left-right wheels independently, which complicates the drivetrain). So in some sense the live axle is even simpler to build. For medium scales, like 13 wide axles, a (clean and solid) driven IFS is just impossible (maybe with a floating diff), we are only left with live axles as a possibility.
  16. gyenesvi
    I'll be honest here since I also plan to try and make an RC version of this model; anything that is not 4WD (or does not keep the live axle suspension) does not cut it for me. It is pointless for me to do a non 4WD motorization for this car as 4WD and live axle suspension are the essence here. Probably it will require some sacrifices though, as there really isn't that much space in there if one wants to keep most of the interior in a presentable shape..
  17. gyenesvi
    Thanks! It should be, as 42114 has the same wheel size (on different rims) and the same wheel arches, so the front and cab could end up looking somewhat similar.
  18. gyenesvi
    Wow, the adventure park set is pretty cool with all that technic functionality inside! This is a good example why it does not make sense to view technic in total separation from system. I hope there will be more and more such official sets that add more use cases of technic structures and mechanism and strengthen the theme. Agreed that front wheel drive is an obviously needed but under-represented mechanism in official sets and there's a great lack of parts for building such mechanisms more simply and compactly, so it would be a great area for development.

    Great model with lots of great functions, I especially like all the detailed functions of the towing arm. Thanks for posting as I have been looking for some more info about this since last year's Buwizz camp. I have been working on a (Ford F350 inspired) tow truck alternate of 42114 in the same scale and color (but obviously with much less functions than this), and I hope you don't mind if I take some inspiration from yours as well for the looks?

    I have never been a big fan of such a solution, because when I tried it seemed to have more slack than the ball joint, and it also seemed to be able to disengage when twisted around (on the other hand the ball joint is pretty hard to disengage from the link). Though in this configuration it might not have enough freedom of movement to be able to disengage. @Teo LEGO Technic, you are right that one big difficulty of the deep rim is that the steering link must be inside as well, so it becomes impossible to make longer steering arms and move the steering linkage further away from the differential for example.
  21. gyenesvi
    Looks really cool, great idea and nice usage of panels!
  22. gyenesvi
    Thanks for testing the motorization with those small Cada motors, that's really interesting to see that it has reasonable speed with just 2 of those. I guess the third motor could also be connected into the drive instead if the fake engine, have you tried how much power it has that way? Anyway, for smaller models than this one, it will be really useful. I guess I'll just have to buy a few more, I only have 2 for now..
  23. gyenesvi
    This solution will result in a slight toe out of the wheels as the steering rack is now slightly shorter than the axle due to the links being at an angle. Not sure if it will be noticeable, but such an imperfect geometry was noticeable in the Ford Raptor for example, though that's a manual build.
  24. gyenesvi
    I love this! I always wanted to go in this direction, but not quite there yet. It looks great, recognizable (love the front grille), and the technical solutions are really pushing the boundaries; the drivetrain is crazy compact, and I like the use of the crankshaft pieces, I did think about something like that but did not put it together as such, I think it's an okay compromise that the firing order is not quite right. I wonder about two things. How much slack does the steering system has because of all the gearing? Second, in the driveshaft, do you really need the second (weak) CV joint at the rear axle? It could the drive just arrive with a straight axle, and the gearing would take care of the tilt angle? This could be a serious contender at the Buwizz camp's mini trial truck competition this year. Are you planning to go? :))

    I was also wondering what that has to do with Lego. Probably some visual marketing megablocks..
