This is KO Propo RSx4s One 10X Response Low Profile Servo w/ Selector4s.This product is a low-profile servo equipped with a coreless motor. The motor, gears, and other mechanical parts have been inherited from the popular "Flection" for its ease of running. The weight is reduced by the plastic upper case. As the 4S series, it has evolved to support serial communication for super fast response performance. In addition, it now supports REAL TIME ICS, which allows ICS settings to be made from the transmitter.
It inherits the same driving feel that was popular with the Flection. The servo is not only based on the standard specifications of "Torque" and "Speed", but also focuses on "Inertia" to provide a smooth turning performance with less stalling while firmly gripping the road surface. With the delicate operation and enhanced torque of the newly developed core-less motor, we have acquired an unprecedented handling performance.
A coreless motor that has demonstrated sufficient performance in Flection is used. The load on the ESC's BEC circuit is lightened, and the probability of the servo dropping out of power due to current consumption is drastically reduced. In order to take advantage of the motor's characteristics, the electrical circuit has been completely redesigned through repeated prototyping and testing.
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.
This servo 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.
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.
