Which is best gear combinations for maximum RPM?  

That's some good editing! I can tell you'll be a big RU-vidr in the Lego community! You got my sub!

And that’s how you build a Lego Air Raid Siren.

I think i have got it. The more the weight and overall teeth of the gear, the more it becomes tolerant to extreme gear ratios. for example small sized and teethed gears would start failing and dipping in RPM at a lower gear ratio, but larger gears with more teeth, like the 2nd example in the video was most tolerant to high ratios

Very nice video! Keep at it with the uploads

Really informative! Thank you!

Could you make a video the same as this but for the most torque?

very cool bro keep making videos

you should add a motor to have more torque when you see the speed drop 😉

how tf do you edit so good? deserved sub!

that spin was good

So.. With the second type if you used metal lego pieces it would go even faster?

Hi I'm starting a Lago project and wanted to know where do you get your Lago from and thank you for your video's I've been watching them it has opened a door in me that I should have been walked through...

Could you make a video of you making a working Lego car
