S9151 Digital High Torque Rudder F3A Servo. This can only be used with 4.8V batteries.
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.
- Dust and water resistant (Not Waterproof)
