Smallest 4-speed Lego Technic Gearbox

Here are the instructions: kzbin.info/www/bejne/eoOaZH-vr52JgdU

[@LucasDynamics_2]

This time with instructions... Thanks!

[@LucasDynamics]

No problem!

[@danielherndl7264]

Every time I think, it's impossible to make a gearbox smaller, there comes someone on KZbin and makes it much smaller. Well done, I am sure, I will need it.

😅 This is why I love to share my constructions with the world...

Next add a clutch

[@wardbox6453]

Is there any way to motorize the mechanism? Would love to see a video on that

[@Sinjinator]

I’ve been thinking about this thing, could this revolutionize the Technic vehicles to give them more ability in smaller sizes?

[@LucasDynamics]

Yeah, you mean that gearboxes could revolutionise Lego-technic cars?

[@Sinjinator]

@@LucasDynamics Yes, and trucks too. You could downshift them when going up steep hills. Also would work for fairground rides to have four speeds. But mostly I was thinking about making vehicles smaller and still having 4 speeds. Maybe smaller RC cars? But then you need an internal way to change gears, or an automatic transmission. Haha you already did an automatic one.

We still are waiting for fastest lego train 2.0

[@LucasDynamics]

You know what. I tested it yesterday and it seemed like everything was working... I will try to upload it this Sunday. Thanks for your reminder😏

How to change gears without touching a gearbox (using remote control)?

[@MisterAJC1]

Hook this up to your Lego turbine

[@LucasDynamics]

With a gear reduction it could work...👍

Turn this video into a short. Commenting for the algorithm

[@LucasDynamics]

Of course mate, just for you: kzbin.infopzhCknJPHuI?si=OXoi50xWaTpHzQ4z
