  1. Cool indeed. What about potential redistribution of the setup for instruction makers? It would make sense to allow some kind of commercial licensing that would require end user to buy the license himself just for a single model that requires the control setup, is best used with it.
  2. Seregiz built this model and made some photos with city tractor set:
  3. I was thinking about doing something like this (small RC model connected to the base) for this contest, but this is a near perfect execution - the drive train is a bit overcomplicated on the bigger mode/base, but thanks to that whole thing looks awesome. Great job!
  4. LegoLounge built the trailer for his John Deere tractor.
  5. Those night photos in contest entry look awesome. Great job!
  6. It's beautiful, but do you have a photo with angled pose like in the first one, but without the box in the background so it's the car on clear background, to be the first in the thread? @Milan frontpage ?
  7. Another lego ideas submission not crediting original creator...
  8. Well, when it comes to either companies having a process of acquiring model ideas/submissions, at least CADA doesn't hold the rights to the model and then not do it even when reaching 10K supports on the platform, to only release the model based on the idea one year later... Better for us AFOLs, but probably Lego knows what they are doing in context of accessibility for younger audiences.
  9. The prototype looks a bit structurally messy, but the new design feels really solid in contrast to that. Can't wait to see it in action as well. Are you planning to increase the speed of movement though between the motors placed in the middle and those axles with worm gears?
  10. I think you're loosing a lot of traffic by not adding working links, especially when it comes to people watching your videos on the phone because it's cumbersome few clicks to manually go to a website and find your MOC there. My trick for my laziness when it comes to adding the link is that rebrickable is still accepting shortening links to just MOC number by removing everything after it like this: -> and this is short enough for youtube to not cut it away and optimise as it sometimes does. Anyway, good model, I have to get some of those tyres and try making something with them as well, because I keep seeing those in really cool small sized models. And also experiment with those rubber pieces you used for suspension, and btw I still need to try building the chassis from your TC20 model with those, gotta see this trick with flexible chassis IRL :)
  11. Cool little model. I'm curious though, as I didn't follow your progress on this one - did you perhaps try doing this as an alt model for the john deere tractor, or was being close to your tractor scale main focus right away? Also curious - what's up with your links to your rebricable MOCs under your videos? Is there a reason why you always have something wrong with them? I remember that youtube did sometimes cut some links off for me, but not for rebrickable.
  12. I've written my concerns about it above. Note that apart from the servos here, there's still need to fit motors and figure out how to connect it to a 4-motor hub. I'm not sure if its worth it, since at this point it's an overcomplication of things that behave similarly to motors connected directly with proportional control and don't behave like differential steering with locked output proportion at all. And with two servos, I'd have to drop one of the turret functions and not having gun elevation in a model of this size would be really weird.
  13. This looks really neat. Especially the snow plow with those teeth and edges detailed out and great proportions between tracks and wheels at the back.
  14. @Ryokeen I was thinking about something like this, but I'm not so keen on having that thin liftarm close to the gears because there's a potential that the gear shifter will push it against the gear teeth if the driving ring is blocked against the gear. Should work most of the time, but it might be touching the gear. I'm leaning towards a single servo mechanism as best compromise, just need to figure out the motor layouts to be solid and don't take up too much of space while having driving axle sent to the back of the whole chassis.
  15. I got stuck on this for a bit longer than expected and I'm not sure which way to go with the steering mechanism. The problem is, that the last iteration of the mechanism works great until I put a lot of weight on it, at which point the path of least resistant when trying to steer is to spin the motor that is not driven at the time instead of it working as a break and thus one side being slower. There's various things I'd like to achieve here, but at this scale I can't achieve all of them: make the steering with two sticks and not one stick is gas and one is servo make the steering work on the same principle as the actual Sherman steering make the steering behave similarly to actual Sherman steering The potential solutions and their drawbacks: single servo differential steering through connection at specified ratio outside of the differential - one stick for steering, not gradual steering angle, configuration is kind of weird when it comes to passing the drive input to the fake engine at the back. dual servo with two gearboxes for steering of each side - should behave like its supposed to, but it's not a differential steering anymore, it's tricky to reinforce and is pretty long because of two servos placement. the actual Sherman-like differential steering that had it's own separate video, but is really huge and it would mean either making the whole model bigger which I don't want to do, or designing quite a few 3d printed elements to shrink differential. The twin gearbox approach would work really well with gradual steering on each stick, but it also means that drive motor(s) need to go somewhere and they would take input from the feature for turret, so I wouldn't have gun elevation anymore. Ideally I would have the motors driven off a battery box, but for that, I'd have to have gearbox disconnect drive output from the drive motors, and then it'd be weird that neutral is in the middle of the stick. On top of that, it's kind of hard to figure out how to reinforce the orange shifters location so they won't slide while also they won't touch the reinforcing elements or the reinforcing elements wont collide with gears near them The single servo steering is the one from this video: Which I think is the most reliable approach, but it's a bit annoying that it's controlled with a single stick. I dropped that approach earlier because it felt like it requires a lot of space, but I increased the size of the chassis significantly from that prototype already and also reworked the turret mechanism multiple times, so It might be the best bet. Still, I'm not 100% sure if I should go this way, or is there a better approach, that's not just going yolo with two drive motors connected directly, which I don't really like, but at the same time it would allow for a cleaner, simpler build. But at the same time, with current weight of the model, the slight difference between motors or how to power is supplied from the hub will mean it won't drive perfectly straight.
