Futaba S9151 Coreless High Torque Servo

Digitally enhanced microprocessors cut about 1/2 of the response time from transmitter input to servo reaction. Digital operation allows this servo to reach full power immediately and maintain torque longer. High-capacity, high-current wire with low resistance. Coreless motor (a wire cage rotates around the magnet). High speed operation for immediate response. Dual ball bearings on the output shaft. Delivers high torque rudder operation for precision fixed-wing F3A pattern aircraft.
