The HS-805MG 'monster' servo is a beefier version of the popular HS-805BB servo.  The metal geartrain makes the HS-805MG an excellent candidate for steering 1/5 Scale vehcles and driving control surfaces on large scale models.  The large case size allows room inside for a beefy motor, huge gears and electronics capable of handling high current conditions.
