This is KO PROPO Aluminum BSx4S-one10 Grasper2 Servo For 1/10 RC. Today's RC cars have evolved and their marginal performance has improved. As a result, some drivers may find that conventional servos are not enough. The new product BSx4 Sone10 Grasper2 has been redesigned from the built-in brushless motor to improve torque and holding power. Grasper's greatest feature, "grasping the road" servo performance has been further enhanced. Even on the latest high-end machines, the Grasser 2 has enough holdingpower. (recommend for 1/10 category). The holding force is the force that the servo shaft tries to hold a position. Grasper has meanings such as "grasping tightly" and "grasping firmly", and is a name that expresses the characteristics of this servo that firmly captures the road surface.

The torque of the conventional BSx3-one10 Grasper was 10.8Kg-cm (at 7.4V), but with the new Grasper2, the torque has been improved to 16.0Kg-cm. This achieved about 150% increase compared to the conventional model. Torque increased by 150% compared to conventional models.

The "4S" servo supports serial. By supporting serial, there are the following merits. The PWM method is the mainstream control method for RC servos. In the PWM method, the angle is specified by the width of the signal transmitted from the receiver. On the other hand, in serial communication, the servo angle can be specified numerically. In serial communication, the communication interval can be significantly shortened compared to the PWM method, and the interval from command to operation is greatly reduced. By combining with EX-NEXT's XT mode, we have achieved an unprecedented ultra-fast response as if you were just touching the machine. The next-generation radio "EX-NEXT" is equipped with a telemetry (two-way communication) function."REAL TIME ICS" can be used by connecting the serial compatible servo "4S" to the B / S port mounted from the new receiver KR-420XT. Servo parameters can be set arbitrarily from the radio without having to collect the machine at hand. It's easier than ever to create a more flexible and in-depth settings without compromise. When using serial, connect to the B / S port of the KR-420XT in XT mode of EX-NEXT.

Grasper2 can change various characteristics to your liking by ICS, but "Frequency (FREQUENCY)" has been newly added from 4S. "Frequency" is a function to change the frequency of the motor built into the servo. By changing the frequency, the servoActivity changes. Direct feeling improves by lowering the frequency. The servo operation becomes active and the machine will bend sharply. The higher the frequency, the smoother the servo will move. The activity will be calm and you will be able to bend smoothly. Please select your favorite characteristics while changing the settings.

An aluminum case is used for the top case that supports the [holding power] that does not shake. By further cutting after alumite treatment, a sharp form with an edge is created (chamfering). Furthermore, by cutting the inner thickness to the utmost limit, it is lighter than the conventional aluminum case while ensuring sufficient strength. Commitment extends to servo leads. The black cable, which looks tight, has the optimum softness for handling while ensuring the required current capacity.
