    4-way power distribution. Input gear can be changed to a 8/24 combination.

    It's a very compact design, nice work. I tried to modify it to eliminate one of the overdrive gears, but didn't have much success. The input of gears 1/3 and 2/4 is linked, and the clutch gears don't differ that much in size, so you can't have wide variations of ratios without complicating the gearbox quite a bit.

    The new parts in 42083 have opened the doors to some new gearbox designs. I saw that @Didumos69 and @Erik Leppen have started working out some potential designs, I think it would be good to have these new gearboxes collected in a single topic. @Jim or @Milan If you think this should be merged with a different topic, please do so. * * * Here is a design that makes it easy to visualize the gear ratios. It's far from compact, but the ratios are well spread out with only one overdrive gear. Yellow - control Green - input Red - output

    ... And lubricate it to reduce friction and damage. I know we like to reproduce mechanical functions in Technic, but this one is a bad idea with plastic parts.

    Theres interesting stuff going on here, but I'm not sure all the mechanisms would work without failing in a physical build. The chain used for the steering may be a weak link (pardon the pun), and the top shock absorber mounts should be braced together to prevent them from sliding away from the frame.

    It's very similar to a worm gear, except the "thread" is a closed loop that has one low, one high and two medium points. When a low or high points is engaged with the gear shifter ring, one of the two red gears is driven. When the medium points are in contact with the shifter ring, neither red output gear is driven. The beauty of this selector is that it can be driven continuously in one direction, and will just cycle between all the states. It can also drive two gear shifter rings at the same time, allowing 4 gears with a single rotation of one shaft. As an added bonus, the output of the gear selector shaft can be linked to a secondary mechanism (gear indicator dial, spoiler with adjustable height, adjustable suspension, or even another gearbox). This new orange ring replaces red gear selector levers and lowers number of parts required to build a gearbox.

    @chox For a second I thought I had typed all of that in French. Then I realized my French isn't that good.

    It's a nice build, nothing to be ashamed of. All the stuff you learned on this one will make your next supercar even better.

    That new orange gear selector can work in a continuous motion, making it easy to link a spoiler or steering mechanism that varies with the selected gear.

    @Kingfisher Considering that this topic is 12 years old, the URL has changed a bit. http://www.youtube.com/watch?v=UmiYGv3KC0s

    Nice solution! Why not drill before sealing to make sure that there are no plastic chips inside?
  12. BusterHaus
    A second Chiron set solves that problem. Just kidding, I realize that not all parts are available in all colors.

    I doubt that the brakes will be functional, as they would wear much quicker than any other component of the set. Lego puts a big emphasis on durability, and I have trouble believing that they'd start selling a set for replacing the brakes. These will be for visual purposes only.

    Don't worry, I won't be posting any more partial instructions. I made these without a cover page and parts list on purpose, so they can't be mistaken for anything that official.

    Instructions for the main frame only: http://www.filedropper.com/greyhound-4wdrcbuggy-copy I stand corrected, this model is quite modular. All these sections can be built off the model: main frame, front axle with servo, rear axles, fake motor, hood and some rear engine-covers. There are a couple of other partial assemblies, too.

    This new Powered Up line will consist of multiple products that vary in complexity, instead of one set that can be used to build multiple things. Some sets might only be battery-powered, while others could be remote-controlled or app-controlled. Some of this functionality will ship with the sets, although kids will be able to buy additional accessories that’ll add features to their builds. This new Batmobile can be controlled through two pre-built remote interfaces on the companion Powered Up iOS / Android app or through a remote that users personalize with sliders and buttons. A new coding interface will also be released later this year so kids can code speed, direction, sound, and duration to create new stunts and movements. https://www.theverge.com/circuitbreaker/2018/5/17/17365328/lego-powered-up-batmobile-connected-set

    I visited this topic a few times now, and it's very fun to watch it evolve. Your part usage is quite clever, and makes the mechanisms look like the real deal. I'll be following the rest of this build with great interest.
  18. BusterHaus
    Makes sense. Your builds are the opposite of modular - I expected the seats to be installed whole, including the headrest. I need to use my imagination a bit more. By the way, I'm not promising anything fruitful (yet) - I was very curious as to how complex this model would be in comparison to the last one. I actually resisted the urge to download the digital files until the MOC was complete. I'll be happy to share any progress if/when it becomes significant. My impression so far is that this is a more complex build than the Hammerhead, at least in some sections. Like the Hammerhead, it's very far from techniques and building styles used by official sets. This helps to give it rigidity, but makes the building more difficult/interesting. As for the seats, I didn't phrase my question properly. I know the seats are mounted tilted back, I just wasn't sure if the angle was fixed, or if the seats could be tilted forward a bit. I saw that in a few places already. It's great for strength, but makes physical disassembly more challenging. The only official set I've seen so far that had similar disassembly challenges was the BWE.

    I played with the currently available LDR file over lunch today and got to a point where assembly was impossible without stressing parts - maybe I haven't figured out something yet (see edit below). Here is a picture of where I'm at, the parts in red are causing me a headache (there's also a 3L brown axle that's over the headrest). Overall it's a very good puzzle to reverse-engineer. By the way, do the seats tilt forward in the physical build? Edit: got a lot further now, but stumbled upon another question - is the disassembly of this MOC possible without stressing parts or using tools?
  20. BusterHaus
    That's quite the accomplishment, Grum! Your great persistence (stubbornness ) pays off in spades yet again.
  21. BusterHaus
    Excellent work, the MOC performs like a real beast. You should be quite proud of it - I think it takes Lego Power Functions components to their limit.

    I am somewhat underwhelmed after watching the video and reading the details. It looks like a BuWizz clone, with weaker voltage (7.4V), and a charging port that requires access from a second side of the brick. WiFi also consumes more power than Bluetooth - maybe they counter this with a larger battery. I'm also trying to imagine a MOC that would benefit from being controlled over the Internet, and such applications are limited - maybe some light switch, or a blinds opening machine? Most of the time the MOC will be visible to the user, eliminating the need for Internet connectivity. The big advantage this brick can have over BuWizz is on the software side, but it's too early to judge that. I apologize for sounding so negative - I was hoping for a real competitor to the BuWizz brick, and I can't see this as one. Maybe someone can change my mind.

    This started out as something called Speed Demon, but I renamed it Drift Demon after building the actual MOC and driving it. The bodywork didn't materialize, but the car did. This project made me realize how far I have to go before I can make a decent bodywork. Powered by: 2 L-motors geared up 3:1 1 servo motor for steering 1 BuWizz unit. The rear suspension is a dragged axle, and each side is mirrored at 180 degrees to save space. The L-motors move with the suspension. Front suspensions is independent. Here is the chassis, it has some elements missing that were added in the rear to stiffen up the frame: A shot from the underneath, although the actual build has some changes: And a video:

    @Jim I was going to request a very similarly worded question - instead, I'll just add my vote for this one. You could possibly ask about "other reasons" why particular functions were not implemented - sometimes the decisions may be driven by financial or marketing reasons. I think a solid answer to this question would end much speculation as to why certain functions are simplified, or omitted from the model.
  25. BusterHaus
    Nice find, @Void_S! The pendular suspension is my favorite for off road performance - I'm happy to see that this MOC had locking differentials, as soft terrain like sand and snow is very forgiving, and solid driven axles really help the traction.
