Stock:

With an Average Radio System:
83°
Your average transmitter and receiver will output a relativly narrow PWM signal range.

Radio System + Servo Stretcher:
140°
Adding a Servo Stretcher to your radio system setup will allow you to achieve wide PWM signal ranges.

Wide Signal Controllers:
140°
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:
110°
Your average transmitter and receiver will output a relativly narrow PWM signal range.

Radio System + Servo Stretcher:
185°
Adding a Servo Stretcher to your radio system setup will allow you to achieve wide PWM signal ranges.

Wide Signal Controllers:
185°
Controllers such as the Actobotics® Servo Controller, Arduinos, and Raspberry Pi servo hats can usually send a wide signal.
