The gears have been upgraded to carborized gears, making them even more durable!
 
With the combination of a “linear hall sensor” and the legendary “S8912SHV 2K” , the S8912 SHV 2k LS will give you a smoother feel.
It is a perfect all-around servo for many applications.
Durability is also improved.

Important Notes on Using Our Servos
Our servos are programmed to operate with high precision and sensitivity.
Because of this, if there are any obstructions within the servo’s range of motion and it is unable to move as commanded by the transmitter, the servo may experience excessive load. This can result in damage to the internal circuit board due to overheating.
When installing the servo for throttle, aileron, or other control surfaces, please make sure to leave a small amount of free play between the servo travel range and the mechanical movement range. This helps prevent any binding or overloading of the servo.
 
The firmware in a 2k servo verifies the position of the servo arm two thousand times each second, 
while the firmware found in previous servos verify the arm's position one thousand times per second.
This greater number of verifications makes for a very precise servo, and gives it a more "solid" feel.
It is recommended to use a booster cable with 2k servos to ensure steady voltage at all times.
