Servos Ko Propo BSx4S Grasper brushless standard size servo – Coming soon septembre 13, 2021 by Chris Leave a Comment Japanese company Ko Propo introduced their new BSx4S Grasper brushless standard size servo intended for the use with 1/10th and 1/8th vehicles. Based on the BSx3-one10 Grasper low-profile servo, the new Grasper features a standard size and offers greatly improved specifications by adopting a new brushless motor. It has a high speed of 0.09sec/60°, and generates a powerful torque of 40.0kg.cm(@7.4V), the highest of Ko Propo servos, making it ideal for the use at demanding locations such as the steering.

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. The black cable, which looks tight, has the optimum softness for handling while ensuring the required current capacity. The length of the cable has been changed from 200mm to 250mm. The durability of the servo has been strengthened to match the improved servo specifications. Stainless steel is used for the final gear. Furthermore, nitriding treatment has been applied to achieve the strength to withstand the maximum torque of 40.0kgf.cm(@7.4V). In addition, the height of the serrations on the final gear has been adjusted slightly higher to allow the use of multiple servo horns. The number of teeth and diameter of the serrations are unchanged. The « 4S » servo supports serial. By supporting serial, there are the following highlights: 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, KO Propo have achieved an unprecedented ultra-fast response. 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. « Serial Branch adapter » ideal for serial wiring. The KR-420XT receiver is equipped with a single B/S port (serial port) for connecting serial servos, and for GP cars, etc., where two servos are used, the optional « Serial Branch adapter » is recommended for splitting the port. This product is more compact than the conventional product by using a smaller base for the branching point, making it easier to store in the limited space of a car. Grasper servo can change various characteristics to your liking by ICS, but « 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 servo activity 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. The Grasper brushless servo will be available in October.
