Key Features

• Coreless motor
• Dual ball bearing
• 24% more torque than previous 3021 servo

Overview

The 3121 is a direct replacement for the 3021 servo. At 46.4 oz./in. torque, the 3121 Mini servo offers 24% more torque than the 3021 servo. It now has the power to handle applications never previously possible with a mini-sized servo. Typical applications for the 3121 include: control surfaces of small to medium sized planes, electric helicopters, sailplanes, pylon racers, or anywhere a high-precision mini servo with a lot of torque is desirable.
