    Interesting. How did you solve the issue with the range? Also what is up with those cut and soldiered PF switches?

    I took the time today to record the model outside, please check the video here: If you want to build your own chassis for the model, please click on the image below to download the LDD file: One more tip for anyone rebuilding the chassis with BuWizz. Use the tracked steer module at factor 0.3 to power the left and right side wheels. This will drastically increase maneuverability. Few additional photos I took outside: I think it really looks in it's element: To conclude, I am suprised how well the model actually crawls in the real world. I expected more issues due to it's heavy rear and high center of gravity and weight. No broken gears or U joints, so IMO this was a real success.

    Or use a third party app to test the motors.

    I hope Backhoe is motorized. Two PU hubs should be able to cover all the basic functions: 4x4 drive (with new hubs OFC) steering front arm raising/lowering front bucket tilting rear arm rotation rear arm main arm raising/lowering rear arm secondary raising/lowering rear bucket tilting

    Did you push the wheel bearing all the way inside? You need to use quite a bit of force.

    Had EXACTLY same, glad I'm not the only one. But in following modules I had almost none extra, so i think they might be most of the spares.

    1. Instruction booklet 2. Pully wheels hold the axle way too strong, stronger than usual.
  8. Zerobricks
    I did that, but the pinhole connector's edge got damaged because the pully wheels hold the 4L axle so hard in place.

    Here are the issues I found during build of my 42100 set: 1. Damaged motor - I had a simillar injury on one of the C+ hubs in the 42099: 2. Actuator's input shaft color is Dark red instead of Orange. Also one actuator seems to have corrosion, while the other has a very rough surface finish: 3. Instructions have a few issues too. The 2L axle here can interfere with the 12 tooth gears if not inserted fully. I'd use a normal cross-pin here: 4. This assembly is almost impossible to take apart without damaging bricks: 5. You can't test the model in third phase. App won't connect to the hubs, because all motors are not yet wired to the hub. I'm thinking contacting lego costumer service regarding actuators, they seem to be a poorer quality than normal ones and they also feel like they are totally unlubricated. What is your opinion on the issues above?

    Use a lienar (central) differential case and a few fixed gears meshing on it. Should work.

    Here's the more or less finished beauty: Compared to the previous 4x4 version here are the improvements: It can climb much steerper hills due to the additional axle in the back adding support and keeping it from flipping backwards Can go over 9 cm tall vertical step (42110's box in this case ) Has more suspension travel, especially in the negative direction (drop) Tandem suspension allows for more efficient driving over terrain Can easily spin all 6 clean wheels on the ground in low gear in slow mode without any gears clicking (was an issue with clean wheels with the 4x4) Reduced effect of the driveline on the suspension due to the increased gear ratio Has 2 working fake V8 engines Working steering wheel Improved steering angle (from 18 to 27,5 degrees) Steering pivot is a stud closer to the wheel Reduced number of motors from 8 to 6 3 seats instead of 2 But there are also a few drawbacks comapred to the 4x4 version: The weak point now is no longer the bewel gears, but the old styled differentials used as 24 tooth clutch gears. I managed to make them slip in ludicrous mode crawling over bedsheets, which is an extreme scenario. Reduced top speed by a factor of 3/5, from 13km/h to around 8km/h Reduced total efficiency due to the additional gears and axle Lack of rear wheel steering Increased weight from 1,6 kg to 2,2 kg due to the extra axle and fake engines Bricks built portal hubs are slightly weaker than the normal portal hubs, so the gears may slip occasionally when reversing the model into the wall. So all in all, there are improvements and a few drawbacks compared to the 4x4 version. But in general the model is more capable offroad than the previous 4x4 version and that's what matters to me the most. I will make a video of it in the following week or two (after 42110 mod). Meanwhile enjoy this gif of the model climbing over some random Technic boxes in Fast mode. (Notice the large suspension travel of the rear suspension).

    Exactly! Nah, just wanted to motorize it while keeping all original functions. Motorizing it through the original gearbox would be exremely inefficient.
  13. Zerobricks
    Yes, it's short and tall now, but I had to give it a big lift to fit the bigger tyres and motors under the original chassis. I will start working on video as soon as the weather clears up a bit.

    I think the paper used in the instructions booklet is negliable by the amount of paperwork companies and institutions waste daily on useless birocracy. But let's return back to the topic, I wish TLG would be able to find time/human resources for the B model. I mean since instructions for B model are electronic, they can still relase them after launch, even if it takes a few more weeks. And if they need more human resources, there are plenty of people (myself included) on this forum capable to work as designers!

    It's gonna be a white rally car according to Promobricks. I expect a RWD chassis with steering and no suspension and simple bodywork, something on the lovel of the Corvette.
  16. Zerobricks
    I started building my copy and noticed a few QA issues already... One motor was damaged and actuator rods look like they have corosion on the metal... Let's see what's the state at the end of the build.
  17. Zerobricks
    I have an intuition you might be moving up north soon...

    Here is my take on the motorization of the 42110. Basically the whole model was lifted to accomodate the bigger wheel, motors and BuWizzes. Model is powered by a total of 8 motors, 4L motors for RWD, 2L motors for FWD, one servo and one M motor. Total gear ratio is 1:3. It uses custom portal hubs in the front which have a pivot even closer than normal ones thanks to the new rims. Rear uses normal hubs and wheels, since they are sturdier. Axles use the original suspension's upper arms as mounting points along with a pair of 9L links for each axle. The original gearbox is connected to the rear drive, so it works normally. Steering is also connected to the original links, so steerign wheel and HOG also turn when steering Winch is motorized using an M motor. Video coming soon.

    Spring loading sounds like an interesting idea, but would cause issues, the second and third axle could touch when going against the obstacle. A pendular chassis might be a better idea. Around 3 kilograms, planning to make a simple body, to keep performance high.
  20. Zerobricks
    I received the missing parts and finished the chassis: As you can see the suspension is very flexible, so the weight is spread evenly over the 8 wheels: And here is an amazing climb over couch's vertical step of over 20 cm height: I need to reinforce the chassis and make the cab next, but so far, so good!

    Sorry for quiting the pic, but yeah. Seems to me the designers wanted to keep the XL motors dead center in the construction, probably used as a load bearing element. This of course means there's a massive power train gping to the sprockets. I think they also had problems with the torque of the 17,85X geared down XL motor caused the tracks to snap, so they added the new clutch. But all in all, it's not THAT bad, there are only 10 gears in total, 9398 had approximately the same to get from motor to the wheel. One thing they could do is to use a combination of a 40Z and 24Z gear instead of 36Z and 28Z, which would allow for even higher gearing.
  22. Zerobricks
    It does with a stud offset, like 20:16, 12:24, etc...
  23. Zerobricks
    It took me and Roni a few hours to decode the protocol for motor from the official documentation and we decided to leave the option in the BuWizz App simply to have a more costomizable option available for the C+ System. The limit for maximum amount of connected hubs should be 7 for Android (Android limitation), while iOS can support more.
  24. Zerobricks
    Great idea sticking the shock absorbers throught the small turntables! Plus points for using Tumbler wheels, not many MOCS using those beauties. I'm gonna be following this project very closely.
  25. Zerobricks
    I just realized one thing. If anyone wants to use the hubs along with normal portal ones, you can quite easily match the gearing. 5,4 gearing of the hubs X 1,67 (12:20 tooth gears) = exactly 9, which can easily be achived with a pair of 8:24 tooth gears.
