  1. my major concern will be the central differentials. I have built a third iteration of my dual-driveshaft car, which features dual central diffs and many other functions. All functions work fine except the central diffs. Here are some renders of the drivetrain (sorry I can’t show you real photos): I was hoping a dual-central-diff-setup will reduce the possibility of gear slipping inside the diffs, but it still happens every time I put it on high gear (low torque). The complete chassis weighs only 1.08 KG. I really can’t figure out how to improve it anymore, could be the result of too much frictions. I’ll probably give it up for future projects. So my suggestion is to be very careful with central diff, it could be the weakest part of the whole chassis even with two of them.
  2. Being a Chinese myself, this is always the kind of topic that I feel embarrassed and ashamed to talk about. Why thief like LEPIN can still survive? Simply because there is a market. There are so many people who cannot afford to buy “luxury toys” like LEGO for their kids or for themselves in China. Most of us Chinese just don’t care if a certain product is a knockoff or not, as long as it is functional and cheap, it is going to be popular. Of course there are many well-educated elites who at least have respects for others hard works and are willing to pay money for it, but to be honest, the majority of the whole population in my country don’t have that kind of awareness. What’s worse is that most of them don’t feel shame at all. What’s even worse, they took it for granted. On the road to modern civilization, we Chinese have a long way to go. So from my perspective, there is NOTHING you can do about copycats in China. Forget about watermarks or any kinds of similar methods. That sounds sad, but that’s the fact whether you like it or not. Even if LEPIN falls, many other LEPINs will rise again. I definitely am not trying to discourage anyone in this community, and I would like to see any kind of actions to be taken to provide a compensation for the creators. I’m not sure if CF is going to work, but it’s worth a try. Every creator will put a lot of work into making instructions if he decide to share it whether for free or not, and he will probably take a risk. I just don’t want to see anyone lose interest in creating because of that risk. I hope we all can build for fun, and share for fun. At least that’s what I did.

    I won’t share .lxf file for MOCs with no real building instructions any more, I’m so sorry about that.

    Thanks. When I first started making instructions several years ago, I had thought about watermark, but eventually I gave it up. It’s a bad user experience, and it cannot prevent those who intend to steal your work from really doing it. I have encountered people making a profit from my free instructions. Being a Chinese I’m kinda numb about piracy, that sounds sad, but I just don’t want to spend more energy dealing with things I don’t want to deal with. So far I haven’t found someone claiming copyrights of my works, I think most people do have a bottom line. Since I’m willing to give my hard work for free, I’m also willing to take the risk.

    I'm totally fine with it. I like building with 62.4mm tires, basically these tires determined that the truck cannot go "too extreme". I will be more cautious for my future, heavier model with similar struture.

    [MOC] Dual-Driveshaft Pickup

    OK, I think I got what you mean. After testing on multiple terrains, I didn't notice an obvious desync on alxes. I think that's because most of the time I didn't go that extreme. I will take a deep look into it afterwards, as well as 42082 when I get my hands on it. Thanks for pointing it out.

    [MOC] Dual-Driveshaft Pickup

    I haven't bought 42082 yet so I don't know what structure it looks like. Also, please forgive me for my poor English, I still don't quite understand what you mean. By "flexes 90 degrees" do you mean something like this?
  9. KevinMoo

    [MOC] Dual-Driveshaft Pickup

    This is the whole drivetrain. Could you be more specific about the desync? I'm aware of the incorrectly oriented u-joints, that's a mistake I always make.

    Thanks. There are too many examples of independently driven left and right wheels, so I thought I should try something different. Besides this is also an experimental MOC, diff locks will be added in future MOCs.

    [MOC] Dual-Driveshaft Pickup

    I haven’t tried high torque output yet, but I think it should have a better performance than single driveshaft at least. You are correct about the u-joints, I always forgot about that I also hate the backlash of steering for this setup, after struggling for a while I still chose this solution simply because it has a better profile look. I mean it looks cleaner from the side. As for the wheels, both axles have really great suspension travels, the front wheels nearly touches the body when cornering with the shock compressed, so larger wheels might be problematic for off-road drive.

    In fact suspension works pretty well, it can keep all four wheels on the ground for most of the time, even on some rough terrains.
  13. If you still remember the Mitsubishi Pajero that I posted about 6 months ago, you will know that there is another 4x4 MOC with similar drivetrain which I haven’t published yet. Well, the model was actually finished long ago, but the video was long overdue for some reasons. Now, finally, presenting my latest MOC: Dual-Driveshaft Pickup. Dimensions: 350 mm (L) x 150 mm (W) x 165 mm (H) Weight: 1237 g Parts count: 1660 pcs Outdoor test video (4K): The main feature of this MOC is obviously the driveshaft, so how does it work? Instead of presenting photos and explaining with lines of words, this time I made a short video to tell you all about it. This is my first time doing voiceover, as we don’t speak English in China at all, please bear with me for my accent and grammar: I’m not sure if I made myself clear enough in this video, so feel free to leave a comment. more photos: Lastly, I’ve already created building instructions, it will be available very soon. Hope you like it and stay tuned!

    Hey Jim, How do you post a picture with a restricted size while the original one is actually much larger? That is very useful when someone wants to see more details and they can just click on it to see a full-size picture. I also use Flickr to host my photos, everytime I post a picture on EB, I just copy and paste the url of a 1024px wide picture, and if I click on that picture it only shows my the exact 1024px one. So how do you do that? Is that a function available only to the admin team? Thanks.
