  1. One suggestion for the front suspension would be to go to a MacPherson strut setup, using a spring taken from a small shock absorber on the steering pivot. This wouldn't be as realistic for this car, and could have trouble fitting under the hood, but would eliminate the need for any upper wishbone. I guess you could even just use a vertical axle for the strut to locate the axle, and then use a rubber band somewhere else for the actual springing.
  2. Nice job finding that! I'll have to pick up one of those in case I ever build a helicopter. It looks super convenient, and I wonder if it'll be used in the official helicopter rumored for this summer!
  3. Very nice! I like seeing complex mechanisms like this one. What is the black ball part you're using in the middle of the swashplate?
  4. Yesterday I got around to thinking about converting the 3+N transmission to a 4-speed, and came up with a solution I'm pretty happy with. It has an unfortunately small range of speeds, but they are still distinct and shift in order. Interestingly, the setup is dependent on the new non-beveled 12T gear to run a chain, although since I don't have one yet, I'm using a 3D-printed stand-in. Here's some pictures of the drivetrain model on its own, giving a good view of the modified gearing: So, the orange loop drawn on the bottom represents the chain, with drives its 16T gear, and then everything along the green line, causing the 20T and 16T clutch gears on opposite ends to rotate at different speeds. The axles the driving rings are kept running at slightly different speeds thanks to the chain drive with the orange line on it. At the top, under the red circle, is the new 12T gear, and at the bottom, in the purple circle, is a 12T gear. The upper driving ring's axle then continues through the blue drivetrain to run the engine. I forgot to take decent pictures of this before putting the bike back together, but the white 2L beam that is used to limit the shifting has to be rotated by 90 degrees in a specific direction relative to the wave selector to make sure that it shifts in the right order. Anyways, I think having a four-speed sounds a lot more impressive than a mere three-speed, so while there isn't really a functional advantage here, I'm happy to have the upgrade.
  5. There've been a bunch of times I've had just a little idea I wanted to post on here, without making a new thread for it. I've put them in different generic threads in the past, but I figured it might make sense just to make a personal thread to share stuff of this sort. Anyways, the first thing I want to share is this ten-sided "Geneva Mechanism" I came up with today. It's using a 10T splat gear with a pretty standard mechanism for rotating it intermittently, as in a stepper. However, rather than having a spring-loaded part pressing against the teeth of the gear as in a stepper, I've got a an axle that locks the teeth of the gear when it isn't being engaged. The same axle that runs the beam that steps the teeth is also hooked up to a wave selector, so that when it approaches the position in which it will have to move the teeth of the gear, the bump on the selector moves a linkage that briefly unlocks the gear, and then automatically locks it again after the motion is done. It's working well in one direction right now, as seen in the video, but it's not working the other way. I think this is because of the sideways force the wave selector exerts on the black beam, but I'm pretty confident it could be fixed with a more thoroughly engineered solution than this proof of concept.
  6. That probably is a factor, but I think the main thing is how the selector pushes the beam sideways. This sideways motion ends up pulling the axle back a bit before the beam has even popped up on the selector's bump, and I think it's this preselection that makes the one side work better than the other. Like I commented, though, I've got a totally different design that works quite a bit better, so I probably won't develop this design any further at present.
  7. And, I already came up with a design I like better... I should probably hold off on posting stuff like this until I refine it. Because of that principle, I'll wait on showing my new design until I decide if it's final or not.
  8. I've got some experience building Lego models with a brushed motor from a ~$100, fast, RC truck, and the planetary hubs have been a lifesaver for that! I'm not sure how it's power output compares to what you've got here, but they're the only way I've found to drop revs to the point where I don't melt parts, without melting parts within the reduction! I've only wrecked one hub so far, after many model, so I'm pretty happy with their durability!
  9. Sweet! Whenever you get around to that, will you provide a link for folks looking to buy some?
  10. So is the idea here that the old ones are better and less likely to jam, or the other way around?
  11. That's kind of funny! I read pistons, and assumed you meant the clear engine blocks that have been reappearing, including in 42130. The 42130 shock is pretty cool, and very stiff, but large.
  12. If you don't need to have the new design without the slots, you could always pick up the clear blocks they used in the '90s on Bricklink, which are pretty much identical and dirt cheap: https://www.bricklink.com/v2/catalog/catalogitem.page?P=2850a&idColor=12#T=S&C=12&O={"color":12,"iconly":0}
  13. Nice choice of a vehicle to model! The 4Runners are pretty neat cars, I think, but have been underrepresented in Technic so far, with the only model of one I'm aware of being a super tiny one I built a few years back. I suppose that's because the majority of Technic builders are European, and the 4Runner is only sold in North America? One suggestion I might make is to not include a center differential. I'm not sure what your plan is, since you said that the one you have in there is a placeholder, but including one will seriously hurt off-road performance, and be unrealistic for most 4Runner trims (I believe the Limited trim has one, allowing for full-time 4WD, but the cooler ones like the TRD PRO have selectable 4WD without a central diff, I believe). The idea for that CVT is interesting! It's a very cool design, and is quite possibly the best-performing automatic transmission anyone has ever built with Lego, so I think it'd be cool to see. It's not realistic for a 4Runner, but realism isn't everything. Anyways, I'll look forward to seeing the finished product!
  14. Very interesting! Also, in this topic that was just posted, there's an image that seems to show a redesign of the hard shock as well:
  15. Didn't notice you were on there! I'm looking forward to seeing whatever comes of that!
  16. Neat! The large scale and Technic-built body are both interesting. What parts are you using in the linkage on the front wheels? It looks like a 17L half-stud-thick beam, so is it: A. A trick of my eyes, and there's actually a few pieces put together (more likely) B. An obscure prototype (Like the 1x16 thin beam on Bricklink that's only a prototype) C. Something else
  17. Very cool! I love your style of filling in all the gaps while keeping a smooth shape. It might not work so well on stuff with a more complex shape, like modern supercars, but these older enthusiast cars seem cooler to me than newer rich-person cars anyway! I didn't realize how realistic-looking your manual shift lever was, so that's pretty cool to see, and the 4WS system is a great addition too. The amount of detail involved makes this kind of car a superb display model. I really like the red tow hook you added! While I really like the idea of being able to make different body panels different colors, I'm not too impressed with either the dark blue/white one nor the black/orange one. I'm thinking this is because they're so symmetrical, which gives me the impression that the panels were swapped (by the fictional driver) merely for aesthetic reasons, but I don't think it really makes a car like this any more attractive to make it two-tone, so his reasoning backfires on me. What I think would be cooler would be to make the colors more random, as if they have been replaced over time with the cheapest available panel, so maybe a black car with a few panels changed to red, and maybe another panel changed to white. Still, I really like the effort you put in to making this car such a detailed model of a modified enthusiast car!
  18. Yeah, they are amazing!
  19. No, I've built the mechanism of this helicopter, and it does have collective, though it might be hard to notice given how much structure is moved in order to do it. In that MOC's thread on here, @Blakbird made some great renders showing how it works, if you'd like to take a look.
  20. Very cool! The truck looks very nice, and the length and number of sections of the boom is quite impressive!
  21. Yeah. You wonder why they felt the need to break their norm for these sets!
  22. Sweet! I was kinda cynical about this part when it came out, and I still don't think it's really necessary, but I've been using mine regularly, since it's often easier to pop in one of these than to put a 3L axle with stop in from the other side. Having a more neutral color will only make it better!
  23. Oh, I wasn't talking about that set, I meant 42121. I'm comparing them now, and CADA has definitely made changes, dropping the part count from 569 to 467 (Maybe mostly because they don't include rocks?), but there is some pretty clear "inspiration"/copying in several parts. They're definitely not as shameless as some, but it's still a shame.
  24. Are you sure they wouldn't release modified Lego sets? I'm pretty sure they did it regularly in the past, and while they seem way better now, the excavator in here: https://decadastore.com/collections/construction/products/cada-construction-equipment-fleet-c65001w-c65005w looks like a pretty close copy of Lego's 2021 Heavy-Duty Excavator. I haven't found any other things on there that look copied, but this one disappoints me.
  25. Wow, that's a pretty awesome set! It looks great, has plenty of electronics and parts for the price, and has fairly realistic functions. Are the linear actuators for the front blade equivalent to the XL Lego ones? This is looking like some kind of golden age, where we can buy a product with the quality of the top MOCs, the convenience of official sets, and prices not too much above the legitimately shoddy knock-offs out there! Is this the first time they've actually licensed a MOC? It seems like a better business strategy to me, since I suspect AFOLs are willing to design sets pretty cheap compared to an employee, and pirating the big fancy MOCs backfires because the main market for them is the same group of AFOLs who are much more likely to realize a set is pirated than the general public.
