This is a High Torque, High Speed Digital Mini Servo from Futaba.
FEATURES: Coreless motor: conventional servo motors have a steel core armature
wrapped with wire that spins inside magnets. In a coreless design
the armature uses a wire mesh that forms a cup that spins around
the outside of a magnet. This arrangement is much lighter, which
results in smoother operation and faster response time.
Can be used with 1/12 or 1/18 scale vehicles and electric helicopters
