GSM 85, Spiral

The GSM 85(A) servo gearbox is mounted to the aircraft structure, via a custom mounting bracket, and is
responsible for transferring the output torque of the GSA 8X servo actuator to the mechanical flight control
surface linkage. The GSM 85(A) houses its internal components within an extruded aluminum
housing, like the GSA 8X. There are multiple variations of the GSM 85(A), all designed to accommodate
various flight-control system interfaces and torque requirements
