The new HSR-8498HB from Hitec was custom designed for the popular ROBONOVA-1 robot and is a great choice to use in your next custom robot project. The HSR-8498HB servo uses super strong Karbonite gears that will never wear out or create sloppy gear lash.  Another unique feature of the HSR-8498HB servo is that it can be built in three different configurations using the custom accessories included in each package. Build it as a standard servo design, or use the custom “idler” wheels to create solid and sturdy robot joints.
