Do you have any plans to try something like that? The fastest Buwizz powered car I recall seeing was around 40km/h, so I'd love to see you really push the limits!

There is an idea, but haven't managed to build it physically yet.

@Zerobricks Jerry, you are blowing everything away with this spectacular story! Congratulations for all the achievements you got with this so impressive hypercar model! I finally got the time to watch the entrire video. This is the sporty kind of joint venture where all the pieces fit together and your baby is playing the major role in the movie.

The original cars´ long wheelbase allows you to put all the motors and even a pair of BuWizz between the seats and rear wheels, so it was perfect to be the role model for that. And I love how this time you have paid so much attention to aesthetic details. What I don´t like so much, is the rims color and design, but that´s obviously a personal taste.

Why do you prefer to use a M motor for steering over a servo in this extreme setup? How would a normal Lego servo respond to the new generation battery/app?

Why is the model so parts-intensive, considering so much of the space is used up by all the devices?

The car uses PU L motor for steering, it is used in servo mode, so it works normally like one with return to center.

All the small details are really part-intensive, especially the studded details of the wheel arches, tiles, curved parts and plate sused in the seats, top of the bonnet, etc... it all adds up.

Incredible! I'm not a car fan with Lego usually, as it's not very technic, just drive and steer at most. Or even multi gearbox designed for pushing. I'm more for real performing designs, and this does that. Having a big amount of power for the drive, and still being able to have powered doors/spoiler etc. Yet from the outside it looks like a regular Lego hypercar, meaning no motors at all.

Only point of concern would be the steering, it seems that there is no centering programmed. I tried to see in the design how you do the steering and I didn't manage to see it very good, but looks like there is a clutch gear? Meaning if it would click you lose your position, and can not really pufet the slider in middle to be sure you're at 0° angle. I saw this inside the building when you were driving ( a lot in reverse also ) the slider was centered, but the wheels steering angle still around 15° on the car. 

This would make the model really hard to handle, certainly at 30+ km/h. (Hence why it ended it the grass a few times)

But it's been a nice movie, interesting to watch and see why you have chosen 10motors for driving.

The car uses PU L motor for steering, it is used in servo mode, so it works normally like one with return to center. BuWizz 3.0 allows you to use any PU motor with a built in encoder like a servo, just like official lego PU sets.

I start the video at the steering part 56m05s, at 56m11s you can see the steering in the app is centered again, but the wheels are not turning forward on the model.

In the shots after you can still see the steering has not been fully returned to center.

They were steering on a spot, if you drive the car a few cm, they wil return to center properly. Also at that time we didn't have an option to adjust the PID parameters yet for a more responsive steering.

Ah ok, that's what I was thinking already, why there was no parameters programmed in your app to be able to adjust the centering. Depending on your last steering input, if you made a left turn and go back to center, it should go a little over center point to right side to make the wheels on the model straight. Same for a right turn, go a little to far with the servo to the left and the model will steer forward again. Guessed guys with your capabilities would have thought of that, and seems you did but later on. Good job!

In all my models driving and lifting, this is needed as coming from one side to a certain angle, or from the other side will always end up in a different position because of the play in the geartrain/motor. Some parameters added to the program can make it go the the exact same position time after time, wherever it comes from.

Again, great work done!

[Scoar Sonander]

What have you done?!? 

Amazing

[_TLG_]

Cool! Very nice shaping and I like the functions!

[Johnny1360]

Very professionally done, amazing work. I actually just read an article on this, from my google news feed for autoblog.

Top notch work!
Impressive acceleration for a perfect model

I just saw it the same place! 

Now I have to nitpick their article.

"BuWizz, a Slovenian firm that specializes in making motors for Lego cars and scaled-down trains."

I don't think they make motors for scaled-down trains. Batteries maybe, but not motors.

"It then stuffed 15 of its electric motors into the toy"

Five of the motors weren't really their company's.

Oh well, I'm glad to see you getting some relatively mass publicity!

[Johnny1360]

So now I find another article, apparently this set will be offered for purchase, only 5,000 USD and a limited run of 50 sets. Will be interesting to see if anyone pays the price and how popular sets like this will become.

5000 USD is nuts. You can buy a real car for that kind of money.

It’s not even USD, it’s EUR, and to add insult to injury you can add European VAT as well

Never underestimate the willingness of the rich to spend ridiculous amounts of money for high-quality stuff! My rough guess is that the electronics make up close to half of the price, but the other half is a ton for the bricks required, even accounting for the high amount of effort required to collect them all. 

[astyanax]

But according to https://buwizz.com/store/ you do get a whopping 38'880 parts for that sum!

The included BuWizz electronics themselves add up to €1285 when bought individually from their store. I guess it could cost you around €2000 for plastic and electronics together.

I don't think €5000 is 'nuts'. From a branding perspective, that is. You have to see this as a brand posting a big flag. Everything about it must make you go "oomph!". Looks, specs, performance, price, everything.

It is nuts, but in the same way a $300k Lamborghini or Ferrari is (and that’s on the cheap end) nuts. This car is sold for the most die-hard fans of LEGO and RC cars, and specifically those with a hole in their wallets. There is definitely a market for spending thousands on a single LEGO build. Just look at some of Lucio Switch’ stuff.

[Hrafn]

Maybe BuWizz can spend the profit from these on website security - I tried to visit the site just now and it was blocked as having malicious code.

[Gray Gear]

For 5000 EUR they should make all metal drivetrain components with ball bearing wheel hubs so the car can at least perform more than once.

Yea... I am not sure I see it the same way.  300K for a lambo or other (ferrari) is not really nuts because the materials, engineering etc. is so much above and beyond cars that are offered at 50 or 60K.  For this model, with the exception of the Buwizz elements, it is all still Lego.  Same material that builds 300-400 dollar supercars (without the electronics).  If you electronics to a Lego supercar, you can add a few hundred perhaps, but that is about it.  Really for the bulk of the item there is no difference in material, unlike what you see in real cars vs. supercars.  

And while the engineering is certainly superior, one can build Bruno's and other's supercars for around 6-7 hundred.  And although this is a terrific build, right up there with other top notch MOCer's supercars, I can't say the engineering is 5 times better.  Can't really say better period.  On par, perhaps, but I think the jury is still out in terms of superiority of other high-end MOCs.  

So, I think 5K is ridiculous.  Even though I could (and I swear, I say this for observation only; this is NO money flex) afford this, I never would buy it.   Top RC cars, capable of 100+MPH, with metal and even other high end alloy parts don't cost this much.  I have a Liebherr 11200 LTM model crane that I paid 1000 for.  No motors, no electronics.  But the whole thing is nearly all metal.  Weights like 30 lbs, with unbelievable extensions, jibs, etc.  and even it cost only about 1/5 of this beast.  

[Gray Gear]

@nerdsforprez Exactly what I was thinking. The engineering part is there, but the materials part is not. No Metal components, no carbon fiber components, nothing.

Let's do a small bit of math:

5xBuWizz: 1000EUR. 10x BuWizzz motor: 300EUR. 5 more motors estimated: 200 EUR max. Bricks+Custom prints+custom wheels estimated: 1000EUR max. Sum: 2500 EUR. Profit: 50%+, >2500 EUR.

Of course this calculation is flawed because they don't pay consumer prices for the BuWizz components and buy all the stuff in bulk, so at least 20% more profit is probably realistic.

Although I consider it cost prohibitive due to the excess of electrical, proprietary components.

Repeating my prior statement. Although this is a real achievement, I find it now is more turning into a marketing vehicle (pun intended) to sell the actual kits at almost 5K EUR.

[m2fel]

Selling this at 5k € is marketing at its best. Creating attention and getting talked about to reach new customers. Nothing to blame. It's a really nice Lego RC car :)
