TAMIYA 72004 - WORM GEAR BOX H.E.

This assembly kit creates a compact gearbox with large gear ratio reductions thanks to its worm gear, making it perfect for applications which require much fewer rotations than the motor provides, such as wheels on a vehicle. With a 336:1 ratio - and using a 3V battery - it gives one rotation approximately every 2 seconds. The gearbox has an ABS plastic case and low-friction polyacetal (POM) plastic gears for superior efficiency. Three different plastic arm types and a motor are included.
