0-GM18 30:1 Micro Geared Motor <p align="left"><font color="00ff66" size="2" face="Arial, Helvetica, sans-serif">The entire motor with gears weighs
only 8.2 grams!&nbsp; They
are rated&nbsp;for
4.5V DC, but we have tested and run them at 9.0V, even up to
12V. Tires can be directly mounted to the 3 mm diameter output
shaft. &nbsp;</font>
