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 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. Built with incredibly durable steel gears, the D930SW is the perfect upgrade from the popular HS-8330SH servo. How Far Will This Servo Rotate? The answer to this question is partially dependent on what you are using to control the servo.Click for a quick video explanation. Stock: With an Average Radio System:90°Your average transmitter and receiver will output a relatively narrow PWM signal range. Radio System + Travel Tuner:151°Adding a Servo Travel Tuner to your radio system setup will allow you to achieve wide PWM signal ranges. Wide Signal Controllers:151°Controllers such as the Servo Commander, Arduinos, and Raspberry Pi servo hats can usually send a wide signal. Reprogrammed: Whether you purchase the reprogrammed option or get a servo programmer and do it yourself, a reprogrammed version of this servo will be able to achieve greater travel than it can in stock form. With an Average Radio System:120°Your average transmitter and receiver will output a relativly narrow PWM signal range. Radio System + Travel Tuner:201°Adding a Servo Travel Tuner to your radio system setup will allow you to achieve wide PWM signal ranges. Wide Signal Controllers:201°Controllers such as the Servo Commander, Arduinos, and Raspberry Pi servo hats can usually send a wide signal.
