This is a servo saver to fit the RCD/Hitec brand servos. A servo saver is mounted to the servo output shaft(normally where the servo horn is attached), and contains a spring mechanism that gives way slightly in case of binding. It is mostly used on the steering servo for R/C cars and trucks, and basically saves the servo gear train from stripping.
