A popular servo for smaller airplanes, heli’s, boats, cars and trucks, the HS-81 offers a fine balance between speed and torque.
The answer to this question is partially dependent on what you are using to control the servo.
Click for a quick video explanation.
With an Average Radio System:
91°
Your average transmitter and receiver will output a relatively narrow PWM signal range.
Radio System + Travel Tuner:
165°
Adding a Servo Travel Tuner to your radio system setup will allow you to achieve wide PWM signal ranges.
Wide Signal Controllers:
165°
Controllers such as the Servo Commander, Arduinos, and Raspberry Pi servo hats can usually send a wide signal.
