    Wohaha! Or as a boat. Btw, don't be surprised when you see a buggy float...

    So I wasn't finished of course . I'm in the process of simplifying things (digitally) where possible and improving a few things I wasn't too happy with. In effect, I removed 129 parts - and counting - and replaced many parts with smaller ones. Shorter beams, shorter pins, etc. The most important things I improved: I made the BuWiZZes removable. They can be removed from below now, without removing or omitting the seats. I added transversal inclined beams behind the seats to better secure the transversal 5x7 frames to which the rear suspension arms are mounted. I also rearranged the groups in LDD, which allowed me to make some cutaways showing the main structure of the whole model.

    Nice progress! I like the engine and how deep it sits. It doesn't need bricks imo, just two orange beams running over it would suffice, but that's a matter of taste. Can't wait to see the gearbox work!

    I think @BusterHaus experienced similar issues. I don't know if he resolved his issues.

    Jet car? I once started designing one in LDD, but it exploded.

    Thank you very much! Please be patient, I will do some updates on the bodywork before I will release it. Thanks! I will be making one more run through the entire build to find things that could be done more simple or be removed completely, then I will regard it as finished. So far I seem to be lucky, as the motors are still working. I hope the lubrication in the motor will be okay. As for the powder in axles holes, I have that too. I think I will follow your advice, also for the turn tables. Here you go.

    Thanks guys! Yes, the BrickController app and using a game controller really adds to the experience. I do have to learn though. This morning I took it out to a perfect spot for making an offroad video, but I drove right into the trench even before I started filming. I think the BuWizzes remained dry, but the entire nose was under water . It's hanging out to dry now. I hope the motors can handle some water??? It was great fun and I think I will do more RC models. I had some points where I hated the BuWizzes for disconnecting so often. Then I thought: this is why I hate electronics and love mechanics. I even thought of abandoning the entire project. I can control reliability of mechanics myself, but I cannot control the reliability of the electronics But now that the problems seem to be 'controlled' and the build is satisfying, I'm really enjoying driving. I'm actually amazed I didn't completely wear out the small turn tables in the wheel hubs after so many hours trial and error. But the most fun for me remains to be making things fool-proof, which is even more rewarding for an RC model. If you don't run into an accident, this model does not need any maintenance after a rough ride. I think the flash-lights are the only volnerable attachments. So thanks @DugaldIC for pushing me towards RC!

    It won't perform similar with one BuWizz. Two BuWizzes can generate more power. Besides that, I don't know if you can attach 4 L-motors ans a servo to 1 BuWizz. If you leave out the seats and the pins locking the BuWizzes they will be removable through the side windows. That's on my list. Just need the time to take it somewhere offroad. I agree. Thanks! EDIT: @agrof in fact the wheel base is the same as your Class 1 Buggy. Only the track width is 1 stud wider, both for the front wheels and for the rear wheels, due to the use of turn-table based wheel-hubs.The body is 2 studs wider. Tonight I configured BrickController to control the model with my new Xiaomi game controller. I tested it outside and it works great! By assigning speed to one joystick and steering to the other, it becomes much easier to take turns at full speed. There is slightly more lag, especially when my phone is not close to the game controller, but as long as I keep the phone close to the game controller it works great. Sofar no undesired disconnections. Thanks @imurvai! I do have some remarks, but I'll let you know in the brick controller thread. Here's a video showing the full speed turns in ludicrous mode. Btw, it hits a trash container twice and looses one of the front flash lights .

    For such a small car it behaves very well! Now you have to clean it .

    Thanks! It sure is fun to build with your kids. Actually my son doesn't really like building (he does like taking things apart), but my daughter likes building alot, especially with Technic. To me, these stills are dope ! I tried making a render few days ago, but it looked uncomfortably naked. I'll try to find them. EDIT: @agrof, I made them again. I think it's not even that bad, see spoiler.

    Thanks @agrof! I will definitely make some quality pictures! Thanks guys! I'm very happy with how it behaves. I think this has partly to do with the fact that I did not minimize weight to the absoulute minimum. Weight adds to the cars inertia and makes it respond lazy to bumps and give a more realistic body roll while cornering. Don't get me wrong, I did optimize a few things, for instance the BuWizzes are positioned as low as possible (under the seats) and the max steering angle is 30 degrees. Of course extra weight decreases performance in terms of speed, but imo handling and roadholding are also important aspects of performance. The car's own weight makes it sink in its suspension for about 40%, which makes the car glue to the ground. Thanks @Lipko! I don't know what would make someone deserve a pro tag, I suppose it's something our @Jims and @Milans would have to come up with. Thanks for trying @BusterHaus! Are you using the Crane profile in the BuWizz app? That is the only way to connect to two BuWizzes. As this is a new page, here is the full-build test-drive video again, with a few indoor video fragments appended. Also some photo's. In a spoiler, because I'm thinking of doing a final outdoor photo-shoot later.

    This morning my son and I had a serious LEGO session. Me laying the final hand on this build and my son taking the remainders of 42056 apart. A few last WIP shots: So I finished the build. Still need to address a few small things, but overall I am quite content. I was a bit concerned about the weight, but it hangs in it's suspension exactly the way I wanted it to. I'm especially happy with the overall ruggedness and the tight steering radius. Nothing got displaced while shooting this video. Btw, the model includes a V8 driven by an M-motor, but I decided to skip the spare tire. Did not have any trouble with the BuWizzes disconnecting this time.

    Here is the latest LXF-file (chassis only), but please beware it's still work in progress. EDIT: Just noticed some parts are missing in the area right above the mounting point of the rear arms.
  14. Didumos69
    Wow, that is really cool! I like it a lot when people take the time to build fidments of my imagination. It seems you are quite up-to-date with your version. You must also have experienced that the newer 5.5L axles in the front wheel-hubs are slighlty too long. The older version - with sharper (less-round) ends - fits better. I happened to have 4 of them. I also stabilized the rear suspension arms with T-bones and moved their shock-absorber mounting points half a stud forward to raise the tail a little. I fear so .
  15. Didumos69
    Good to know! I agree it adds to stiffness and coherence.
  16. Didumos69
    Very nice! I like the idea of being guided by what can be achieved with LEGO Technic. I will be following this. I never built your Koenigsegg One:1, so at the risk of labouring the obvious: Is there any longitudinal beam running through the entire length of the rear axle module? In other words, can you simply pull it apart length-wise, or is it somehow form-locked?

    The Bugatti Chiron is not my favorite either, even though I am thrilled about this set. To add to the critique, the distinctive curve running along the roof, bending down to the bottom and underneath the doors does not breath speed at all imo. It feels more like a braking parachute. To me this car is a big question mark laying on it's back .
  18. Didumos69
    This was indeed mentioned when the Porsche was about to be released, but it's really a myth. A normal car is made up of about 30.000 parts, let alone the number of parts in a Bigatti Chiron. But even if the number of subassemblies of the real car would come close to the LEGO counterpart, it would be a ridiculous constraint imo. If you pick the right subassembly level, you can always make the granularity approach the LEGO replica. People want to see features and looks replicated, as realistic as possible. Who cares how the number of parts relates to the number of parts used in the original?

    Continued building yesterday evening. It's slowly taking shape. I have good faith the model can be carried around by the roof when all is done.
  20. Didumos69
    Nice solution for the 90-degree limiter! When you have the frictionless connectors I would like to see a video showing shifts.
  21. Didumos69
    Neeh... Put this on repeat for 12 hours and you'll probably end up with a game-changing gearbox
  22. Didumos69
    Very interesting build! To harden the front suspension you could use a setup that squeezes the springs from two sides, just like in 42056, but with 2 shocks. I see two options, one based on your setup (left) and one that I used in my rugged supercar (right). The left one gives slightly less ground clearance (max suspension arm angle of 10 degrees) compared to the right one (max angle of 13 degrees). With the Porsche wheels the right option gave me two studs ground clearance, which is quite a lot, so I suppose for a rear wheel drive supercar the left option would give enough ground clearance. Also, the left option should be slightly more rigid.
  23. Didumos69
    I doubt that too, it was more that I feared battery protection was activated unnecessarily. I have the problem of disconnecting BuWizz also in the slowest mode without pulling the speed slider to the max, so overcurrent would really be unlikely. I somehow still fear there is something wrong with BuWizz 2 that cannot be resolved in any App.
  24. Didumos69
    Very nice @jb70! You also managed to reduce the shifter to it's essence. I suppose the required movement is also much less now, about one stud. From this it is only a small step to a stepper that works in both directions, also the base of my AWD gearbox with V8.
  25. Didumos69
    What if you would combine it with connecting the drive shaft to the right side of the gear box, that is the 12t gear side instead of the 20t gear side?
