Zero's workshop

I hope you get good results during competition. Please let me know, if this type of angle connection (12T + 12T, used in 6x6) is strong enough and doesn't skip under load.

Thank you for the kind wishes! As long as the bevel gears are inside the part 48469, they can handle quite a lot of torque before skipping. I'm using same parts in my Universal offroader V2 and they have yet to skip. Of course, having 5,4 downgearing in planetary hubs reduces the strain on those gears a lot.

Great models, can't wait to see how they perform. Good luck!

About the "Fish", I like the looks and that you have switched to gears instead of cv joints, but I thought you were going to take full advantage of it and have a higher steering angle (around 30°) with putting the steering rack closer to the pivot point. Also it's somewhat long, are you worried about the manouverability of it on slippery surfaces (understeer..)?

I'm not very experienced with tracked vehicles with suspension, how do you keep the tracks enough in tension so they don't fall off?

Thank you for the praise, my friend,

I could increase steering angle to 30° but usually such high steering angle is not needed, since the cars are small and tracks have plenty of space. Indeed the model looks long, but it's actually not much longer than the Bolide for example. The soft front tyres should help with understeer.

Regarding tracked vehicle, the shock absorbers of the suspension arms are under slight pretension, which I hope will be enough.

Hi Zerobricks. I’m a big fan of yours. Your the biggest reason I bought a BuWizz 3.0. It worked so well I’m planning on buying another BuWizz 3.0 so that I can use 4 BuWizz motors. I want to moc a Lego set that can go faster than my BuWizz Porsche 42176. I was thinking of using your instructions to do the Ferrari gte 488 42125. Except to edit it to use the higher motor for speed than the lower motor for torque like how u did. Do you think this could push the model to go over 25km with out breaking anything or is there another Lego set you recommend I use? 
 

apologies if this wasn’t the best place to ask you this, I wasn’t sure how to best reach out to you. Thank you for all your content. Your awesome at what you do.

Thank you for the praise! Regarding the gearing question, when using 81.6 mm wheels with fast output, I was able to reach some 30 km/h. So I think 25 km/h or close should be doable with 68.8 mm wheels. And I think 42125  is a good candidate, though perhaps use the newer hubsamd cv joints to hold and drive the wheels.

Thank you for the fast reply. I’m a little confused with all the options for hubs and CV joints. What Lego set is a good example that has the new ones to hold and drive the wheels?

[Zerobricks]

42160 is the best one for that.
