ProTek RC 270SBL Black Label High Speed Brushless Tail 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.

NOTE: If you experience glitching or poor performance while using a Futaba transmitter, you must turn off BLS mode. BLS mode is only compatible with Futaba BLS type servos.

This is my tail servo of choice since returning to the hobby. I really like the way they chime when powered on without signal, the soft start into position rather than jumping to the command position during power up, and they are very robust. The removable cables are by far THE best feature of these servos. I would recommend both the SBL's and the TBL's to anyone looking for a fast, reliable, durable servo. They are installed in all of my machines.
