D777MG Servo
Hitec's low profile D777MG servo has evolved directly from their popular metal gear HS-7775MG and HS-8775MG. With 32-bit high resolution, ultra-response technology and wide voltage operation, the D777MG is the perfect solution for hobbyists requiring a low profile servo with an efficient coreless metal brushed motor.
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:
90°
Your average transmitter and receiver will output a relatively narrow PWM signal range.
Radio System + Travel Tuner:
144°
Adding a Servo Travel Tuner to your radio system setup will allow you to achieve wide PWM signal ranges.
Wide Signal Controllers:
144°
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 relativly narrow PWM signal range.
Radio System + Travel Tuner:
190°
Adding a Servo Travel Tuner to your radio system setup will allow you to achieve wide PWM signal ranges.
Wide Signal Controllers:
190°
Controllers such as the Servo Commander, Arduinos, and Raspberry Pi servo hats can usually send a wide signal.
