Pre-Order

The KO Propo BSx4S-Grasper STD (SCH-KO30220) brings the acclaimed Grasper holding power to a standard-size, brushless platform. Delivering 40.0kgf.cm of torque and a swift 0.09sec/60° response at 7.4V, it combines speed, strength and precision for confident steering and consistent control. A reinforced stainless steel final gear and robust aluminium cases help this servo handle demanding driving conditions while maintaining crisp feel.

About Holding Power

Holding power is the force with which the servo output shaft maintains its position. True to its name, the Grasper concept focuses on firmly “grasping” the road surface, enhancing cornering performance with stable, precise positioning.

Key Features

  • High holding power in a standard-size case
  • New brushless motor for improved speed and torque
  • 40.0kgf.cm torque and 0.09sec/60° at 7.4V
  • Reinforced stainless steel final gear with nitriding treatment
  • Slightly taller output spline serrations to suit multiple servo horns (tooth count and diameter unchanged)
  • Hard alumite aluminium gear
  • Dual ball bearings and hard servo gear shaft
  • Aluminium top case and aluminium heat sink middle case
  • Black cable with gold-plated connector
  • Serial compatible and HCS compatible
  • Made in Japan

The "Grasper" series, which has been well received since its launch, has achieved its characteristic "high holding power that seems to bite" in the standard size as well. The basic specifications have been greatly improved by adopting a new brushless motor. It has a high speed of 0.09sec/60°, which is in the response class, and generates a powerful torque of 40.0kgf.cm(@7.4V), the highest of KOPROPO. In addition to this, the Grasper STD with its strong holding power delivers cornering performance worthy of the name "Grasper".

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.

Reinforced stainless steel final gear
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.
