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.
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.
Weight: 2.75 oz
