0-72001 Planetary Gearmotor - Tamiya 72001 <p align="left"><font color="00ff66" size="2" face="Arial, Helvetica, sans-serif">This
Planetary Gear Box is a VERY durable, precise, high quality gearbox with
a RE-260 motor built into the gearbox. A wide range of gear ratios can
be attained, depending on how many stages you decide to add (8 different
possibilities!). Two kinds of crank arms are supplied for a wider range
of functions. </font></p>
<p align="left"><font color="00ff66" size="2" face="Arial, Helvetica, sans-serif">Buy multiple
motor kits and you can combine stages to further increase torque and decrease
speed. 3 kits in series would provide 1 shaft revolution every 4 days!
Great for experimenting with gear ratios. Some assembly required.<br>
