Another thing, this might explain the curiously low price of the 42160 Audi.

Odd... some people were saying it was proportional, but maybe only with some control sources? I'll test it with Buwizz 2, anyway.

Just purchased 2 CADA buggy motors and 1 CADA servo, I'm excited to see how they compare to real Lego electronics, and Buwizz motors.

Or a splitter for powered up plugs, or maybe its not powered up...

Faster than the racers series that gave us the buggy motors? I'm skeptical, but excited!

I think that's because I washed some off before taking the photo, but it was some time ago now and I may be misremembering.

I think they're still a bit better than the old ones, but with more use, probably. They're a pretty good option.

Well, I've put a few hours on some more of them and (admittedly it was going 26km/h sometimes) the wheel hub seems to have gained more wobble, like the old two part ones. I was using extra lubrication, as well. I'm talking about the side to side wobble of the wheel attachment points relative to the rest of the hub. But that's, IMO, a huge improvement over the old hubs which would have just melted or come apart, like they did in the buwizz peugeot 9x8 mod.

Its hardly a world record breaker lol, the buwizz team got 60km/h... As for the weight of the tires, in my hands they feel lighter than the same diameter lego ones. They're from a chinese manufacturer called "Injora" if anyone's curious, I found them at a great bargain on aliexpress. Anyway, thanks for the praise!

Well, I finally built a bodywork I don't absolutely hate for my 26km/h car: So while I don't actively despise it, looking at it from above is not pleasant. But at this point I'm just happy to have not torn the rear suspension apart and turned it into a trophy truck. I suppose that'll be next. It doesn't need the rubber bands on the suspension, but I like the extra bounce they give it. Any thoughts, comments, suggestions, are most welcome and appreciated.

You could ask lego support for a new motor, or try completely rebuilding the rear.

Hmm, I could try other things in the future, but at the moment for the time and money it costs it seems just buying original lego tires is better value. As for the 3d printed mould, thats not really the issue so much as filling it consistently. The high weight comes from the walls being very thick, so It would be easier to remove the inside of the mould. The part that would be in contact with the surface is 4.6mm thick, and doesnt feel as strong as I'd like. Thicker is simply too heavy. The tire also smells like silicone, which I'm not enjoying. Your method is an awful lot of work, but it seems to be turning out better. Also, I didnt realise other people on yt were making tires the way I am, I just kinda thought about it for a bit lol. How heavy and large is that tire? Lego rim for comparison?

Perhaps my expectations for speed were a little high. It was about 6km/h I think. Could you send a photo of the gearbox?

Is it a really complicated winch? Whats the big custom track for?

6x6 with 1BW motor per wheel and planetary hubs is guaranteed fun. Though when I built one it felt a bit slower than I'd liked. If speed is important you'll want a gearbox. Either way, I'm excited to see what you come up with next!
