With its low profile design and strong standing torque, the HS-77BB is a great choice for wing or tail mounting in aircrafts up to 1.20 size. Submarines, boats, cars and trucks can also benefit from this servo’s strength and compact size.
The answer to this question is partially dependant on what you are using to control the servo.

With an Average Radio System:
Your average transmitter and receiver will output a relativly narrow PWM signal range.
Radio System + Servo Stretcher:
Adding a Servo Stretcher to your radio system setup will allow you to achieve wide PWM signal ranges.
Wide Signal Controllers:
Controllers such as the Actobotics® Servo Controller, Arduinos, and Raspberry Pi servo hats can usually send a wide signal.
