KO BSx4S-One 10 Grasper 2 Servo

Grasper's unique holding power as like grasping the road has been further strengthened.
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)

- What is holding power
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.

- Torque increased by 150% compared to conventional models
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.

- Implemented a "4S" system that supports serial
The "4S" servo supports serial. By supporting serial, there are the following merits.

(1) Ultra-high-speed communication dramatically improves response.
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.

(2) Servo parameters can be changed from the radio at hand
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.

- Added "Frequency" as a new parameter
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.

- Compatible with conventional systems (PWM)
It can also be used in HCS, which has been well received, and in normal mode, which can be used for a wide range of models.

【HCS】

The communication processing time between the receiver and the servo is compressed to 1/4, and it can be used with a direct operation feeling.

[Normal mode]
System used for servos and ESC’s that has been adopted formany years. It can be used with many receivers.

- Serial / HCS / normal mode switching method.
The servo automatically switches depending on the port connected to the receiver and the mode setting. No additional options are required for mode setting. If you want to use it serially, connect it to the B / S port of KR-420XT. Also, when using with HCS, it can be used simply by connecting to channels 1 to 4 set in HCS. The same applies to normal mode. Of course, it can also be used with the KR-418FH and other receivers that have been released so far. * Only KR-420XT can be used for serial mode. For conventional receivers, use HCS or normal mode.

- Tight black and silver new color aluminum top case
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.

- Easy-to-manage black servo wire
Commitment extends to servo leads. The black cable, which looks tight, has the optimum softness for handling while ensuring the required current capacity.

- 5 patterns of presets available
Five presets are installed in the model memory of the Grasper2. You can use them properly according to the machine and road surface. Please use the servo model selector to switch the servo function that can handle various situations with one servo.

Model 1: For high grip asphalt track (default)
Model 2: For carpet track
Model 3: For middle grip asphalt track
Model 4: GP sedan(1/10)
Model 5: Aggressive
* Since the holding power of the 4th and 5th settings is very strong, a creaking noise will be heard when in neutral, but this is not a malfunction.

There may be slight vibration under no load, but this is not a malfunction. This servo sets the parameters to optimize the driving condition. Therefore, when viewed with the servo alone, the output shaft may generate slight vibrations or drive noise, but this is not an abnormality and does not interfere with operation.
