The Mercedes F1 car has new, slick tyres, pushrod suspension in front and what seems to be pullrod suspension in the back. There also seem to be new, smaller wheels and tyres on the smaller, studded F1 car, about time.

Well done! Can you show the front, portal hubs in more detail? Any issues with the wheel falling off?

The controller support will be released in a stable, public version soon, I just tested it today and it's almost ready and it supports all functionality including power and gearbox controls. Please have patience, thank you.

It was a plan to use them in the future, but nothing as of now.

Correct, the expansion port has only 4 pins.

That's because it's the weekend........ BW 1.0 didn't have Ludicorus mode and other small differences.

Could you please type this in a way that's a bit easier to read by using sentences or paragraphs?

Well done, Igor! I like how you used the flip flop beam with the steering rack, great idea and should be very robust!

This turntable change came out already in the 42144 and I think 75313. I think the reasons for redesigns and reinforcment are material change, though I also think that 42146 also played a big part.

Might be faster to just take it apart and restart IMO. Also are these original LEGO pieces? The black doesn't look really black on these photos.

I am refering to the dark bluish grey 28 tooth differential. EDIT: My bad, I was wrong. How about using no differential or double axle drive with 12 tooth bevel gears? Or you can simply offset the diff and drive axle by a stud to the side.

A 6L suspension arm will allow the normal diff to pass under it, so you don't have to put them at an angle.

Don't forget if the gear ratio is 364,5 the Earth does one additional revolution going around, so the end gear ratio is actually 365,5. More context:

Seems like a twist on the 3 studded flip flip beam, simillar as they did with a 5 one, turning into an L one.

Thank you for the praise. What do you mean with visitors? Indeed, I'm really happy with it and I dare say it's one of my best MOCs so far. Keeping things as small as compact usually results in much more lighter and robust builds, it's totally worth it!

I think there are small train wheels used instead of 2x2 dishes inside the small ring foor support.

I also believe that the SETs are held to a higher standard than MOCs. I've only built one very popular MOC from another, famous person and I was verry dissapointed with the lack of structural integrity and usage of flex axles fo everything, furher reducing bodywork strength. It was a big empty shell, the driveline was way underdesigned (using 2 XL motors to drive a ball joint, breaking U joints constantly). I think once you start building models professionally and for non-experienced end users, you see how important stability, ease of building, color coding and part optimisation are. And that kind of limitations plus more are also imposed on LEGO's designers. So in short, IMO MOCs are usually overrated and generally not build up to the same spec as SETs.

Bravo to everyone for reverse engineering! Can someone count the number fo gears? I'm curious.

These sets seem minifig scale though.

Since both sides are mirrored, the new knob gears arent really needed. The only thing is they offset the central, control axle by 45 degrees which is not needed.

I think they use a bevel 12 tooth gear, because it's less likely to get damaged/damage the ground if pushed over something - ir has rounder corners than a straight version.

I don't understand why a new knob gear is needed here?

Any way you can reduce weight? Perhaps try with removing the crane and helipad first? Also chimnies and observation deck seem quite heavy and high.

I actually taught myself to ice skate Thank you for the praise. Here you go, it's a very simple design:

Well, I think it's safe to say it drives better than expected, see for youself here: I was worried the cold temperature will be an issue, but as you can see the model can spin all its wheels, drift, skid steer, etc even on asphalt! Enjoy a few nice outdoor photos, showing the detailed front here: I may have forgotten to mention that you can of course open the doors and see the working steering wheel: Here's the model in a more industrial setting: Lastly while recording, I stumbled on a bottle of a Jack Daniels, so I took the opportunity to make this silly photo: As usual, there are more photos and LDD file in my Bricksafe folder: https://bricksafe.com/pages/Zblj/112-audi-s1-e-tron As shown, the model has a crazy power/weight ratio, it's really fun to drive, powerslide and drift around. Since it's so overpowered, the play time is quite long - I drove it for at least an hour in the cold while recording the video. Mechanically, there were no major issues - funny enough the brick-built CV have shown to be more reliable than the hub CV joints, one of them got slightly damaged. But that can easily be avoided by not steering at maximum lock while spinning the wheels against each other I'm even thinking of taking the model to the ice skating ring to record even more stuff, but that will probably be next year. So to conclude... This is one of my final models for this year and I think I really ended it with a proper bang
