Stock:
With an Average Radio System:
89°
Your average transmitter and receiver will output a relatively narrow PWM signal range.
Radio System + Travel Tuner:
158°
Adding a Servo Travel Tuner to your radio system setup will allow you to achieve wide PWM signal ranges.
Wide Signal Controllers:
158°
Controllers such as the Servo Commander, 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:
111°
Your average transmitter and receiver will output a relatively narrow PWM signal range.
Radio System + Travel Tuner:
198°
Adding a Servo Travel Tuner to your radio system setup will allow you to achieve wide PWM signal ranges.
Wide Signal Controllers:
198°
Controllers such as the Servo Commander, Arduinos, and Raspberry Pi servo hats can usually send a wide signal.
