AC20-05H-A01
Features

This is a general-purpose servo module compatible with Futaba’s proprietary S.BUS/S.BUS2 protocol.
The module employs a coreless motor, offering a relatively low-cost solution while delivering one of the highest torque levels in the standard-size class.
An aluminum heat sink and metal gears are used to improve heat dissipation and durability.
Using the optional CIU-3, users can change the default operating angle and configure free or hold settings.
