HS-5055MG Servo

The HS-5055MG servo is the digital, metal geared version of the popular HS-55.  With this servo, Hitec takes ultra micro performance to the next level without breaking the bank. The new HS-5055MG is a perfect choice for ”smaller” high performance electric helicopters, aircraft and sail planes.

How Far Will This Servo Rotate?

The answer to this question is partially dependant on what you are using to control the servo.

Stock:

With an Average Radio System:
75°
Your average transmitter and receiver will output a relativly narrow PWM signal range.

Radio System + Servo Stretcher:
126°
Adding a Servo Stretcher to your radio system setup will allow you to achieve wide PWM signal ranges.

Wide Signal Controllers:
126°
Controllers such as the Actobotics® Servo Controller, 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:
119°
Your average transmitter and receiver will output a relativly narrow PWM signal range.

Radio System + Servo Stretcher:
178°
Adding a Servo Stretcher to your radio system setup will allow you to achieve wide PWM signal ranges.

Wide Signal Controllers:
178°
Controllers such as the Actobotics® Servo Controller, Arduinos, and Raspberry Pi servo hats can usually send a wide signal.
