  1. Great proof of concept model! It definitely has a better and simpler drivetrain than version 1. Would it be possible to apply the same principle to a single motor RC car? i.e. the gearbox selects between 6 combinations of forward/reverse and left/right/straight.
  2. Great model! Nice shaping and lots of detail. This is what 42000 dreamt of being.
  3. On the image you can clearly see 3 pins holding the wheel on, indicating the presence of a hub. Given the weakness of the standard CV joint hubs and the difficulty fitting wide 81 mm tires to portal hubs, I think they will probably be the new planetary hubs from 42099. I also wonder what kind of suspension there will be space for. The small gap between the front wheel and fender makes me think the front axle will be fixed, while the small amount of lengthwise space between the rear axles due to the 81 mm wheels makes two separate live axles unlikely. I suspect the rear axles could have simple stabilized pendular suspension like 42122, or a tandem live axle like 42043 in the best case.
  4. Very nice mod! They should have made it a long haul truck in the first place. With the cad model, is possible to do a size comparison between 42128 and other trucks like 42008, 42078, or even 8285?
  5. I wonder what the performance of 42129 will be like compared to 42099. Assuming smaller tires, planetary hubs, and solid axles, I don't see any advantage except for more torque on a straight incline, due to coupled drive motors. Unless there is a really amazing suspension and drivetrain.
  6. Really nice mod! Adding independent bucket articulation is the first thing I would have changed for this set. The boom is no longer as sleek as the original, but it should be a lot more playable.
  7. Nice model! The bodywork isn't super amazing, and the wheels look a little small, but it's still quite recognizable. The suspension looks a little flimsy, but it's also compact. It's great to know that non-sequential gearboxes can be programmed into PU, congratulations on putting in the effort there. Any idea what the approximate ratios are in the gearbox? It's kind of hard to see what the gear meshes are in your pictures.
  8. If this set had 62.4 mm tires it would be really nice, but they will probably continue the current trend and use 49.5 mm tires. If it has pneumatics and no motors, does that mean a return of the manual pump from 42053?
  9. As a way of adding more mechanical complexity, could the CAT have 2 C+ motors and a gearbox to operate the blade and ripper functions, similar to 42114? I am thinking 4 ports on the hub = 2 drive/steering motors + 2 motors for distribution gearbox. The gearbox could then output to multiple actuators for the blade and ripper, resulting in anywhere from 4-6 motorized functions including lift/tilt of the blade and ripper. It would be a logical evolution of 42114's gearbox, although it would not be realistic compared to the multiple hydraulic actuator circuits on the real thing.
  10. If the Zetros is similar to 42070, PU and a license could make up the price increase. Hopefully it will have proper live axles like the previous licensed Mercedes trucks, 8110 and 42043 did.
  11. The sticker-free pictures for comparison are much appreciated. I wonder if the relative lack of functions in this set is to avoid competition with the 1:8 series. If the 1:10 car sets had a transmission too, the only thing setting the 1:8 cars apart would be a slightly larger size and slightly higher level of detail, which would make the $200 extra hard to justify. I'm thinking of picking this one up for the parts, maybe on sale. It's frustrating to have the suspension setup so similar to 42077 and 42096, which isn't the best for this kind of car. The first thing I'd mod is making the suspension more like 42039, then give it an HOG somewhere.
  12. I wonder if the blade will be entirely brick built or if it will use a new huge single-piece mould.
  13. Very impressive! Hope it works just as smoothly in real life. Now I want to get the set just to mod it. If only something could be done to improve the winch too...
  14. I'm impressed that Lego put full suspension including the two hard springs on a set this size, but the looks of the front end just aren't doing it for me. The hood seems a little too long and the headlights stick out way too much.
  15. I think that the slightly oversize wheels/fenders and extra suspension travel/ride height give this model a bit of a rally car appearance. It doesn't match the track car designation, but it's not a bad look for the model. The wheels wells are still a close fit compared to 42039 or 42077.
  16. This is a very nice piece of art! Lots of detailed shapes to draw the eye. I had no idea gears came in those different colours.
  17. I feel like 42125 is slightly overpriced compared to recent sets in a similar price range. I did a little research (see below) and several other sets have better value in terms of number of pieces and functions/motorization. Even the most similar set, 42096, has a lower cost per piece. Maybe red parts cost more? price USD part count cents per piece 42125 $170.00 1677 $0.10 licensed 42113 $150.00 1636 $0.09 licensed PU 42096 $150.00 1580 $0.09 licensed 42098 $180.00 2493 $0.07 42078 $180.00 2595 $0.07 licensed 42069 $180.00 2382 $0.08 42054 $180.00 1977 $0.09 licensed PF
  18. I agree, looks better with less stickers. It's so nice to have a red supercar again, feels like a successor to 8070 minus the power functions. And it's great to have all these relatively new curved panels in red and in a set cheaper than 42115. I really hope the suspension is not another clone of 42077 though, maybe something like 42039.
  19. This one's looking really good, especially with all the nice angles in the side profile. I'm not entirely sold on the colour scheme though, would prefer something a little more traditional. Hopefully it doesn't pull to one side when driving like 42109 did in Sariel's review, although with an identical drivetrain the chances are pretty high it will drive the same way. If it's not fast enough with the new tires, larger diameter ones should fit on the back too.
  20. I didn't think I'd like this set when I saw the prelim, it looked boring and square. But in red and white in the official pictures it actually is pretty cute. I'm impressed they fit the gears controlling a 2 degrees of freedom bucket in such a small space.
  21. Lego really pulled out all the stops on the bodywork for this car. It even has opening doors! Although the front fenders are still on the square side compared to real life. Another way to check if it has a differential is reverse engineering the rear chassis in LDD and seeing if it would fit.
  22. I'll second that. 42070 seemed huge when I first built it, I didn't realize the new Volvo was just as large. Any idea how 42114 compares with other huge flagships (e.g. 42055, 42082, 8110)?
  23. Would it work to have a 36:12:20 gear mesh? Or 28:20:12? Something like the below layout. I'm not sure if the final gear ratio is what you want or not though. 36 (XL) : 12 (center) : 36(XL) 20 (output) The only trick is to make sure the vertical gear mesh is well braced.
  24. This is one of the best Lego shooting mechanisms I've seen, especially in terms of capacity and rate of fire. I thought of using flywheels like that, but never got around to trying it out. Using an elastic is a great way to keep the flywheels pinched! Several Nerf blasters use hoppers, but none of them work as well as yours.
  25. Very interesting video! Knowing these ratios will be very helpful when designing gearboxes. One thing thing to note, I think you implied this, is that having a specific ratio between gears only optimizes the efficiency when the final gear ratio is chosen so that the motor is operating close to its peak power.
