D941TW Servo
Hitec’s D-Series servo line sets new standards for advanced, programmable technology. Powered by their 32-bit MCU (Microcontroller Unit) and 12-bit ADC (Analog to Digital Converter) industrial science, these powerhouses dominate the servo arena. Their potent combination of wide voltage capabilities, high resolution, rapid response, and patented Smart Sense technology brings maximum performance to all radio control applications. The members of this particular D-Series group are all designed with extremely durable titanium gears; and the D941TW, D946TW and D951TW trio boast full metal cases. When you demand ultimate reliability and unprecedented advanced engineering, look to the power of the D-Series servos!
How Far Will This Servo Rotate?
The answer to this question is partially dependent on what you are using to control the servo.

Stock:
With an Average Radio System:
72°
Your average transmitter and receiver will output a relatively narrow PWM signal range.
Radio System + Travel Tuner:
120°
Adding a Servo Travel Tuner to your radio system setup will allow you to achieve wide PWM signal ranges.
Wide Signal Controllers:
120°
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:
118°
Your average transmitter and receiver will output a relatively narrow PWM signal range.
Radio System + Travel Tuner:
198°
Adding a Servo Travel Tuner to your radio system setup will allow you to achieve wide PWM signal ranges.
Wide Signal Controllers:
198°
Controllers such as the Servo Commander, Arduinos, and Raspberry Pi servo hats can usually send a wide signal.
