BSx4S-Grasper Std w/Selector 4S

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.
