The analog HS-225MG represents a good value with performance that rivals other larger and more expensive servos. Ideal for applications that call for a small, lightweight, high speed, high torque servo, the HS-225MG high performance mini servo features a top ball bearing and is built with state-of-the-art SMT technology.
The answer to this question is partially dependent on what you are using to control the servo.

With an Average Radio System:
87°
Your average transmitter and receiver will output a relativly narrow PWM signal range.
Radio System + Travel Tuner:
191°
Adding a Servo Travel Tuner to your radio system setup will allow you to achieve wide PWM signal ranges.
Wide Signal Controllers:
191°
Controllers such as the Servo Commander, Arduinos, and Raspberry Pi servo hats can usually send a wide signal.
