Hitec’s expansive line-up of servos include the HS-755HB and HS-755MG “giant scale” servos offered with either the revolutionary Karbonite™ gears or metal gears. Both are perfect for larger R/C applications and feature dual ball bearings with a water and dust resistant case. The powerful HS-755MG delivers a whopping 200 oz-in of torque and the HS-755HB delivers 183 oz-in of torque at 6 volts.
The answer to this question is partially dependent on what you are using to control the servo.

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