9G Servo Mount.

These are servo mounts for 9g servo motors.

They are designed so that the armature (rotor) is close to the mount surface.

The first is designed so that the armature can do a full 180 degree swing. (Double)

The second is designed to take up as little room as possible, the armature can only swing up to about 120 degrees before it will hit the mount, depending on the armature used.
