ProTek RC 170SBL Black Label High Speed Brushless Servo (High Voltage/Metal Case

Brushless servo technology has improved by leaps and bounds. Finally, brushless servos can deliver holding power, speed and precision that can compete with a coreless servo. Combine that with the superior efficiency and lifespan of a brushless motor and you have a servo that hits all the marks, with the performance and quality required for a pro level build. 
A black anodized aluminum case with aluminum and white accents give this servo a stealthy look that sets it apart from the rest. The aluminum upper case provides bomb proof durability and the heat sink center case offers efficient heat dissipation and helps to reduce weight. The lead wire is detachable, allowing you to easily custom tailor the servo lead to your application, and the package includes both 135mm and 285mm length servo leads. Plus, a full selection of servo arms and mounting hardware are included making installation easy.
