Getting its name from the way the gears rotate like the planets around the sun, the Planetary Gear Box is a precise, high quality gearbox with a RC-260 motor built into the gear box itself to add to its compactness. A wide range of gear ratios can be attained, and two kinds of crank arms are supplied for a wider range of functions.
This is a Planetary Gear Set from the Technicraft Series by Tamiya. FEATURES: A highly versatile system for reduction of high RPM electric motors to high-torque low RPM applications. Often used in precision instruments because of the reliability and accuracy of the unit. The RC-260 motor included in this set utilizes carbon brushes for long motor life.
