Tail Servo Step-Down Voltage is ideally designed to step-down a voltage source of 6 volts that is outputted from any external BEC (battery eliminator circuit)  down to 5.2 volts.  This allows an external 6 volt BEC to be used with Futaba servo models 9241. 9251. 9253. 9254. 9255. 9256 and other digital servos that are not capable of handling 6 volts.  The Tail Servo Step-Down Voltage is equipped with male/female servo

plugs and is ideally used in series with the RC model’s gyro and rudder servo to prevent any harmful damage overloading to your servo.  The Tail Servo Step-Down Voltage can also be used with any other applications that require a step down power voltage of  approximately 0.8 volts.
