Tamiya 72005 6-Speed Gearbox

i m wondering if this gearbox is self locking… as i m using it in a pulley system … i m worried that if it is not, the load will cause the pulley to unwhine itself once the motor stops

Hello,

The comparison table at the bottom of each Tamiya gearbox page shows which gearboxes have worm gears. They are the 70103, 70110, and 72004. The 6-speed gearbox does not have a worm gear.
