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 the entire “D” line, these technologically-advanced servos are powered by our 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. Their unprecedented programmability and wide-voltage capabilities deliver the most progressive, leading-edge performance for all your 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 we expand our outstanding D-Series product line.
