The HSR-1425CR is a special motor designed for continuous rotation servo operation. Double ball bearings on the output shaft provide long life. Essentially, it is a geared motor that can be controlled by an RC servo controller. It is not normally used as an actuator as there is no possibility of telling it to move to a specific position, as is the case with a standard RC servo.

Normal servos can be adapted to continuous operation, but the problem is that the position range that causes the motor to stop is very narrow. Servos for continuous rotation can move forward or backward at different speeds, depending on the position they are in. With an adapted continuous rotation servo, the position range for the different speeds is very narrow, making it difficult to achieve a certain speed.
