The KO Propo BSx4S "Grasper STD" High Speed Brushless Servo, is great for high holding power in a standard size servo. The basic specifications have been greatly improved by the installation of a brushless motor. It has a high transit speed and generates powerful torque. In addition to this, the Grasper STD with its strong holding power delivers cornering performance worthy of the name "Grasper". With the advancements made to the Grasper STD the torque has been improved to 611.04oz-in (44.0kg-cm) at 8.4V. This achieved a dramatic increase compared to the conventional model. Included with this combo is the Selector4s Programmer to make parameter changes.
Implemented a "4S" system that supports serial
By supporting serial you get Ultra-high-speed communication that results in improved response. 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 this servo with EX-NEXT's XT mode, KO Propo achieved an unprecedented ultra-fast response as if you were in the drivers seat. Radios equipped with "EX-NEXT" (KOP10661), can make adjustments through the radio. "REAL TIME ICS" can be used by connecting the Grasper2 to the B/S port found on the KR-420XT (KOP21013) receiver.
Added "Frequency" as a new parameter
"Frequency" is a function to change the frequency of the motor built into the servo. By changing the frequency, the servo feel changes. When lowering the frequency the servo operation becomes active and the servo will move aggressively. The higher the frequency, the smoother the servo will move. You can select your favorite characteristics while changing the settings.
Compatible with PWM Systems
The Grasper2 servo will function with standard transmitters as well. However, the communication processing time between the receiver and the servo is compressed to 1/4. This compressed communication will lead to a different feel when compared to serial input.
Serial / HCS / normal mode switching method.
The servo automatically switches depending on the port connected to the receiver. No additional options are required for mode setting. For serial use, connect it to the B/S port of KR-420XT. When using with HCS, the servo can be used by connecting to channels 1 to 4 as set in HCS. For normal mode, the servo would be plugged into the port as instructed for that radio.
NOTE: 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 static noise, but this is not an abnormality and does not interfere with operation.
