HS-7985MG 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:
67°
Your average transmitter and receiver will output a relatively narrow PWM signal range.
Radio System + Travel Tuner:
113°
Adding a Servo Travel Tuner to your radio system setup will allow you to achieve wide PWM signal ranges.
Wide Signal Controllers:
113°
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:
117°
Your average transmitter and receiver will output a relatively narrow PWM signal range.
Radio System + Travel Tuner:
195°
Adding a Servo Travel Tuner to your radio system setup will allow you to achieve wide PWM signal ranges.
Wide Signal Controllers:
195°
Controllers such as the Servo Commander, Arduinos, and Raspberry Pi servo hats can usually send a wide signal.
