This is a High Torque, High Speed Digital Mini Servo from Futaba.
Coreless motor-a conventional servo motor has 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 resulting in smoother operation and faster response time.
Nylon Gears
Designed for 1/12 or 1/18 scale onroad cars such as the HPI Micro RS4, and also best performing tail-rotor digital servo for the t-rex, shogun or any micro heli, this servo works best on 6 volts.
