ProTek RC 170SBL Black Label High Speed Brushless Servo.

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.

Great servo. It is my first time trying out the ProTek servos and it has proved to be a top notch from my experience so far.
It has taken a good amount of beating but it is still going very strong.
The finish on this is phenomenal. For about the same price, you're getting a brushless high speed servo that can cost you twice as much when you buy other brands.

Give it a try!)

The 170 is by far the best servo I've used to date. The detachable leads is key and I can only hope that trend continues with future protek models. I've been using Protek's for a while now and even though they have caught up to other "top brands" in price they've always matched them in performance in reliability and the 170 is no different. I'd recommend this servo to anyone!)

Was blown away with the performance of the protek 130ss. I wanted to try the 170sbl. Wow. This servo is in the top 5 best performing servos on the planet today! Some of the best centering i have ever seen! And. As far as build quality goes. Hands down the finest constructed servo i have ever seen.)

Good servos but they have a glitching issue with the Futaba 4PX. This is a known issue according with Amain support team, right now not using them because I am not able to solve the problem at least from my side.)
