KO Propo "BSx3-one10 Power" Low Profile High Torque Brushless Servo. 

HCS (High speed Communication System)
This is a high speed communication system between the receiver to the servo. The HCS mode shortens communication time of the signal which is compressed. HCS compatible servos is changing mode automatically by signal from receiver. So HCS compatible servos can use with all receivers. If you want to use servos by HCS, please use with HCS compatible receivers.

Brushless Motor
The BSx3-one10 Power provides a strong retentive power while achieving a direct feeling of operation by the use of a Brushless motor. The cornering characteristic has a linear feeling while driving at high speeds or on a surface that has high grip.

The RSx2-one10 series: all essential parts such as the case, the gear, the motor are made in Japan. At the domestic factory the close inspections are executed through the delivery to secure “Thorough Made in Japan” product reliability.

2.4GHz & High Voltage Optimized

Current servos have the appearance of high speed and high power from the response of 2.4GHz and the power from Li-Po batteries respectively. This creates a huge demand upon the servo. The RSx is the racing servo with the durability and operability to employ this high-spec demand.

You can change servo's setting when you use KO Propo "ICS Servo Manager" software. Adjust the parameter of stretch for more retentivity in High grip condition, less retentivity in Low grip situation, You can select value based on the surface grip for the best servo performance.
