You're right, previously I only checked my blog post where I wrote "around 4 hours", so I looked at the speed build footage to be precise - it was 4 hours 36 minutes Having the parts arranged helped a lot.

It took me 2 hours do disassemble the A model and sort the parts then 4 hours to build the B model.

I think the M motor and the fake engine does not add a significant amount of weight compared to the overall weight of the car, so I'd keep it. Had a similar setup on my 42037 RC mod, the M motor did not have a visible effect on the performance.

Yes it works, just tested it for you. You have to use the old extension cable:

Not yet, we'll have to wait what comes with the new app version. Since this requires a certain level of programming of the output I don't think it will be included this time (at least it was not on the list). At the moment you can only do it with an SBrick sequence as far as I know.

Thank you guys, the workflow is much better this way! Having the source window there helps to control the metas. @roland is there a shortcut to jump to the current step in the source window?

Really like the menacing look, and the adjustable suspension is a very nice extra! Hah, it's the same in Hungary, cannot find an hour to film outside without rain/snow/freezing rain

Lol, thanks for that but I will not enter :) Cool competition with very nice prizes but I don't think it would be fair to enter while my video is on the entry page :)

Thanks @roland, I guess I'll have to stick to a workaround then. About the meta items in LDCad like the buffer exchange - if I add them to a step they're not visible, only appear in the code. Is there a way to visualize these meta steps/commands in the application itself or I need to track them in the file itself? One additional question (hope you're not too annoyed...) - I see there is a rotstep meta available as well, is there any documentation available how it works in LDCad?

As I'm experimenting with buffer exchange now in LDCad I encountered another challenge. I put a piece to a temporary position and I would like to move that to the final position only after several other steps. If I add the buffer exchange store/retrieval meta accordingly that means not only the piece I'd like to move will disappear but all the other pieces I added during the interim steps. Does it mean that I have to re-add those other pieces as well in the same position or is there another method to exclude the non-moving steps from the buffer exchange?

Amazing, many thanks for your help! Took a couple of minutes to figure out how to use it but succeeded at the end :) If someone needs the exact steps in the future I'll leave them here: drag & drop buffer exchange storage meta to the screen Add part in temporary position add next step drag & drop buffer exchange retrieval meta to the screen (part in temporary position disappears) Add part in final position

Thank you @roland for the hint! Based on what I read so far I'd need to switch to MLcad to use buffer exchange or add the necessary code directly with a text editor. If I understand correctly the support of buffer exchange is implemented already in LDCad as well, are there any instructions available how to use it? I found some instructions for buffer exchange on this page, but when I opened the attached example file in LDcad I cannot really do anything with it, cannot select pieces etc.

I did not find an appropriate topic to raise this question so I hope it's not a problem to open one. I'm building a model in LDcad and trying to create the instructions with LPub3d. I have some pieces / parts of the model that needs to change position between steps, like pushing a 3L pin in place or rotating an assembly by an axle (like at the end of step 45 of 42077 A model). Is it possible to do with LPub3d?

@TechnicSummse I agree it wouldn't be easy but certainly not impossible. I had to do the same with a touchscreen and two virtual sliders.

I can tell you about that part how "easy" is to reach 40 km/h with BuWizz But to stay on topic - as you have tons of motors and RC units now, why not to go simple and try a similar config like my BuWizz record breaker. You'll need to have more power as the RC units are heavy as mud, but something like a 4 wheel setup, 4 RC units, 8 motors, no any moving parts from steering, just steered with the speed difference of the motors on the two sides.

I created a video to show the setup process of BuWizz 2.0 and the different profiles, there's usually some confusion as the description provided is not too detailed (and has some errors as well). There's also a speed demonstration and some fun with ludicrous mode:

Amazing, thanks for the video! Can't wait to see it running outside

Haha, I know the feeling Sitting in the room while it's raining outside and can't really test the 4WD 42077 with ludicrous mode either

Buggy looks great with the new tires! Would be cool to see a video with high/ludicrous mode activated Do you have a tripod to film? (Btw Power puller tires are very similar in diameter/width but much-much heavier)

An interesting article on Promobricks about the new PF 2.0 controller: https://www.promobricks.de/lego-patent-einreichung-offenbart-details-zur-neuen-fernsteuerung/53202 I used google translate to read the German text so there might be some misunderstandings, but in essence they describe a patent of a remote that has buttons to control forward/backward motion, and there's a center piece in the remote that can be turned by 90 degrees to switch to left/right control. As they say it looks like the remote seen at the toy fair. The idea is really interesting, I wonder how sturdy this solution will be. Another concern with the buttons is the proportional control, how will that be achieved?

If you step on the Lego RC off-roading path be prepared for such injuries, especially with a BuWizz powered vehicle

@Didumos69 you don't need to pair the BuWizz like a BT headset. Download and open the BuWizz app, start to set up a simple profile with one BuWizz first. The blinking state with BuWizz 2.0 means it's ready to connect. If it's solid green it means it has connected to something, apparently to your phone as you tried to pair it. Turn off the Bluetooth service on your phone, restart BuWizz, then try with the app. In the app open the first profile, click on the setup button. Assign one output to one of the controls, and with the icon in the top right corner you can select your BuWizz unit. On that screen click on refresh, once your BuWizz unit is found select it and go back to the previous screen. Then go back again with one screen - you should see there the big "start engine" button. Tap on that, as the light goes around the button the blinking green light on your BuWizz unit has to turn solid green and you should see the controls. Let me know if it doesn't work, I can make a short demo video what needs to be done.

Valid point It didn't last long actually, I guess everyone has a "first time" for such things as well

I just realised today that a screenshot from my 42077 review video is used to advertise the Lepin clone of this set :( It is very easy to identify it as I accidentally built the center lights upside down and they used this image for the preorder ads and it is used on most aliexpress ads as well... I assume there's nothing I can do with it, but it's really frustrating to see my work reused to advertise fake products :(
