The Goteck range of digital high torque standard size servos are up there amongst some of the best for quality and reliability at a price that offers excellent value for money. The top and bottom cases are made from a high strength fiber reinforced nylon and the center case is CNC machined from solid 6061 aluminum, this acts as a very good heatsink for the motor and amplifier.

The HB1621S offers a metal geared, high voltage digital servo with a brushless motor that has exceptional torque and a blistering speed. Ideal for all types of models where very high specs in a standard size case are required. This servo is very happy to operate on 6~7.4v making it ideal to run directly from a 2s lipoly battery.
