HS-785HB Servo Hitec

The HS-785HB servo is unique due to its ability to rotate multiple turns while retaining positioning feedback.  While most servos are limited to approximately 180 degrees absolute max, the HS-785HB can rotate just over 8 turns given the proper PWM signal range.  With most hobby radio systems the HS-785HB servo range is likely to be just shy of 4 rotations (assuming a 1050-1950usec PWM signal) however when using the servo with a servo controller capable of sending a wider PWM range (Arduino, Raspberry Pi, Pololu Servo Controller, etc.), the servo is able to be driven further without any modifications necessary.  This large scale servo has wear resistant Karbonite gears and an output shaft supported by two ball bearings to ensure years of reliable service.
