Using this for a rotational speed controller on my tank turret! Thanks!

[Matthewattardo]

So cool! And it isn’t too big! Congrats!!

So cool, also looks like you're missing some clutch before the gearbox

Hello
I’m looking for assistance in designing a LEGO Technic gearbox specifically tailored to work with a LEGO vacuum engine mounted on a car chassis. The gearbox should include a neutral position along with 2–3 forward gears. The gear ratios need to accommodate the high RPM output typical of a vacuum engine.

I believe incorporating a clutch mechanism would be essential to prevent the engine from stalling. Additionally, I’m considering the integration of an electric booster motor to assist in low gear for initial movement. The system should be RC-controlled.

Any help or guidance would be greatly appreciated!

Did i make something wrong, its work fine at the begining. After a while the small red axle be broken a stuck in servo motor hole :((

Thank you! :) But I wonder....I built it acc to the instructions. Checked it once more but the 4th gear rips the system in parts. It is connecting two different gear ratios, namely the outer input with via the big gear and inside using the standard connection gears. It does not work. Can you help?
