## Description

The 90 tooth, MOD 0.8 gear can mate with any MOD 0.8 gear, but when building on pattern, the most common partner for this gear is a 30 tooth pinion gear or servo gear. Using the pinion gear, you can create a 3:1 underdrive or overdrive setup (depending on your application). When used with the 30 tooth servo gear, this combo creates a 3:1 underdrive that facilitates slower speed and three times the torque.
