SKU:
$16.99

A popular servo for smaller airplanes, heli’s, boats, cars and trucks, the HS-81 offers a fine balance between speed and torque.

How Far Will This Servo Rotate?

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.
