This is the Hitec D955TW Monster Torque Titanium Gear Digital Servo. The power of Hitec’s D-Series servos continues with the introduction of the next Premium Class trio: the D930SW, D954SW and D955TW. As with Hitec's entire “D” line, these technologically-advanced servos are powered by a 32-bit MCU (Microcontroller Unit) and 12-bit ADC (Analog to Digital Converter) industrial science and possess Smart Sense engineering with rapid, high resolution response. This servo features unprecedented programmability and wide-voltage capabilities to deliver the most progressive, leading-edge performance for all radio control needs. The reliably-strong titanium-geared D955TW replaces the well-known HS-7955TH. Advancing servo technology and providing superior engineering has always been Hitec’s mission and that continues today as they expand their outstanding D-Series product line.

A fantastic addition to my SMT10. A BEC is a must if you want to get the full potential out of this servo. Rest assured it is up to the task once you do.
