2K servo means that the servo control frequency has been increased from the previous 1kHz to 2kHz (regardless of whether it is PWM connection or XBUS connection).
By doubling the control frequency, movement has become smoother and responsiveness, neutral holding power, and initial torque have also been improved.
Hunting has been greatly reduced, and a smoother operating feel has been achieved.

The V2 version of this full metal mini servo boasts a stall torque of 17kgf-cm.
The motor has been changed, and the focus has been placed on extending the servo's lifespan rather than on torque.
The newly designed metal case maximizes the rigidity of the middle case by fastening the upper and bottom cases with separate screws.
The metal upper case eliminates distortion in the gear train, eliminates unnecessary load on the motor and dramatically improving servo lifespan.
Furthermore, the metal B gear and the 10mm diameter double bearings built into the top and bottom of the output gear transmit the powerful motor power to the output without any waste.
This is the ultimate power servo that defies conventional wisdom about mini servos.
