HSR-1425CR Servo


The HSR-1425CR is the continuous rotation version of the HS-425BB.  The speed is proportional meaning that the further the PWM signal deviates from the idle signal (approximately 1500usec) the faster the servo will rotate.  If you're looking for the smoothest continuous rotation servo, be sure to check out the HSR-2645CRH or HSR-2648CR 25 tooth spline servo.
