Nice. How reliable is it? I saw the indexing mechanism on technicbricks a while back, very nice :thumbup:

It is reliable as the standard 4 speed Lego gearbox) The difference is that it has another gear sequence.

I would like to understand how it works ! Can you write a review of your invention explaining how everythings fits inside? Thanks in advance !

The base is the module, which has 6 fixed positions, but we need to get 4 (amount of gears), that's why it's necessary to use 24:16.

To make the work of servo motor easier - 12:20

Added a new video (the same link at the beginning of that topic)

Thanks, I have understood how it works. Great invention. Nevertheless, you should add a clutch mechanism because during gear change, two gears can be engaged at the same times !

Build gearboxes is fun, I have done three or four, but until you put them in a car you don´t see if they work well or poorly, having clutch is essential of course. An example with a car for more than 3 kg and a Sheepo gearbox with modifications. I like to see more videos working with the car, obviously failed MOC :thumbdown: .

i've tried the one i posted in the post above but the gearbox was actually multiplying the ratio instead of dividing it....so i should have inverted it....one day i'll work out how to make it work properly for a car use :)

This one is very interesting, idea is useful, but it needs modifications to work with servo motor)))

Hi guys! Nice gearbox! :classic: How long did it take you to make it? Would this work in a car? I tried to make a gearbox and I couldn't seem to get the right gear ratio from the L motor :sceptic:. It didn't have enough torque in the 3 and 4th gear.

Happy building! :sweet:
