I plan to buy 4 more buwizz 3 after your controller support is functional(already have 4 now), without BC2 I wouldn't have bought them in the first place. You really should pay @imurvai something, at least respect

Cant agree more, buwizz is developing their own controller support however still not functional. It would be great if BC2 can fix this problem so we don't have to rely on buwizz development. You can even charge for it, you deserve that. Also when using PU L motors for steering, we can choose motor type as servo, so it will work in BC2, that is what I do now, however the angle max is only 180 degree, so the turning radius is extremely small, can you make a bigger up limit like 720 degree? @imurvai

Thanks a lot! I still cant connect to the batteries so no way to try it. I think I should wait until the software is functional and stay with BC2 for now. Hopefully they can make it at least as functional as BC2. That's good, got basic functions done first. Please do support control one channel with different buttons/sticks like BC2! Right now one channel can only be controlled by one scroll bar, that's also one of the reasons I only test my mocs in buwizz app(mainly to see power consumption/currents) and in real playing I only use BC2. wow thanks for sharing! Bought it, it could be used as a FPV screen support! I use DJI action 4 and it is very fluid.

umm what kind of bar? I use pliers, and it's hard to do so I always be very careful when to decide inserting that part into one way holes

Thanks! Tried it, only worked once, after that even without using a controller, buwizz app showed I am not connected to the batteries, but all 4 batteries were connected because the green light is constantly on. Tried multiple times all failed. Now I can only use brick controller 2 app if I keep the buwizz beta. Also, after I click the controller icon, I cant see my previous control layout anymore, it was just blank, with nothing.

Thanks bro! Hope they can do it sooner. I am sick of using touch screen to control mocs, and when using brick controller 2 buwizz 3 batteries almost alwasy shutdown, for any serious power output.

I downloaded testflight and buwizz beta, but there is no option in buwizz that could connect to ps5 controller, anyone got some kind of instructions? Or they still didn't push the update out?

Thanks! So not required to use extention ring with short driving ring. Then all is ok. I thought there would be some kind of additional functions require the extention ring. I have many of those rings in my collection but never know why to use them...

Anyone can tell me what's the extension ring is for? This is the short driving ring 2L, it is supposed to make the build compact right? Then why add another extension ring to it?

wow this is very interesting! clever design! this one too! the concept is definately interesting. I myself use custom made planetary gears and turntables a lot, but never used the 28t turntable this way! Edit: watched second time and saw you are using 46490, not custom made. still very interesting!

So after the 4 sequential gearbox with new parts from 42159 failure on heavy load, I designed a new one, which is just 2 shifts, with symatrical planet gear like design to distribute the load, it successed on 4 buggy motors power! However today I wanted to push the limits and added 2 more buggy motors, it can generate 326 grams of down force! With a total of roughly 12A currents, that's 140 watts of electric power. That's the new record for me, but shortly after this run, when I run it again, it failed, turned out one of the planetary carbon axle melted the beams that holds it, 3 beams were destroyed. Just like I said earlier, even with symatrical design the planet gears would also cause trouble, but it is indeed effective, compare to my original 4 sequential gear box design, which is not symatrical. This gear box has gear ratio of 1.8 & 0.6, so you can guess that I used 8 teeth gear, this is dangerous though, it can only work on the planet axle, because 8 teeth gear can handle max 3 buggy motor torque, any more than that it could be deystroyd instantly. So my conclusion is, a lego gearbox can only handle 4 buggy motors power at most, any more than that, you need more gearboxes(Which is what I'm going to do on my next car). Video: Strange why it's not working? This is video on flickr, when editing I can see it, but after publish it's gone, wth... Anyways the link: just delete the space https: //flic.kr/p/2p4mrJL

impressive! thanks for sharing, I see you cant keep up with your truck hahaha:)

I think diff lock has very low load, the lock simply hold the wheel still that runs in the air. it should work there

Absolutely. However most people play lego technic with very small power motors, look at all these official sets, no one even use more than 2xL motors for the drivetrain(correct me if I'm wrong), which is equal to just one buggy motor power. When you play with 4 buggy motors or even more, things are very very different. I cant even imagine using rc brushless in lego through lego gearbox, one rc brushless can have 2000 watts transient power, that would melt any plastic beam holes... Nothing wrong with small power though, it's us who are like maniacs using big power in plastic lego

Because under torque the ring would be pushed out of the clutch, and it would also be hard to put it in the gear in the first place. However You have to have a real load in your system to test the robustness in your setup, just running it idle won't show you any serious problems. Contiuous load is not easy to build, I use a propeller, I can generate 300 grams down force with it, imagine the load.(FYI this force can lift DJI Mavic mini drones) And a gear box motor can not really hold it in position in heavy load, unless you use a worm gear. For you question do you mean this one? You can put it in, it's very loose. but no, no click.

I happen to disembled the gearbox for the 24 toogh gear with clutch, and my conclustion is the same. New ring groove is too shallow to handle any serious torque, you can put it with the wave selector and make it work, just much more easier to fail than the old ring. And by my defination that is not compatible. Also with the old ring and 3 L connector, you can lock it in place by a "click", with this new one it was locked by the 8 teeth yellow big gear and rubber band + beam in Yamaha design, if you pair the new ring with the old orange wave seletor, you gotta figure out a new way to lock it in place yourself. But in the end it's lego, you just do whatever you want with whatever way you can do. don't let a word of "compatible" or not restrain you:)

You mean this one from OP? My bad, didn't pay close attention, it's indeed impressive, I would never use so many u joints in a moc like this, I would worry so much about broken u joints or slipped out axles

Thanks for the info, I see that's for real cars, I doubt we can do the same in lego....

Yes but in lego mocs it's mostly twin drive shaft for tatras I think, left side & right side driven by different set of motors. For your twin beam suspension I thought you can also use this method. Left & right wheels won't be aligned though(and that would be like real tatras).

Nice job done! I use metal u joints and carbon axles myself too, also rc tyers, but didn't go all the way to metal bearings and custom parts. Buggy motors are powerful enough for lego builds, so I didn't try brushless either. Do you have videos?

good point, but you can still drive it like tatra right? didn't try but seems workable

yes that's my thought. plastic axles generally deform first, so I won't use them in any situation with a torque higher than 3 buggy motors(or higher than one xL motor native output)

That's my thought too, a bit like tatra suspension. Definately cool though.

you broke the connectors before the axles they hold broke first? did you use carbon axles on these?

wonderful demo! Yes it would be stronger, I have tested it vs bare axle. but it would be still not as strong as a carbon axle, because the weakest ling of this system is still a thin plastic axle, not the connector
