KO PROPO - KO BSx4S-Grasper Std w/Selector 4S - KO30221

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".

The included selector allows you to switch between preset models.

5 patterns of presets available

Five presets are installed in the model memory of the Grasper STD. You can use them properly according to the machine and road surface. Please use the servo model selector to switch the servo function that can handle various situations with one servo.

Model 1: Power saving high
Model 2: Power saving low (Factory setting)
Model 3: Balance
Model 4: Performance
Model 5: High performance
* Since the holding power of the 4th and 5th settings is very strong, a creaking noise will be heard when in neutral, but this is not a malfunction.

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.
