February 20, 2017Application(s): For rocket airbrake control
Comments: My rocket is supposed to launch miles high and I am using this servo to toggle my airbrake to control the altitude. As a dry run, I tested the servo +/- 90 degree with 20ms step of 5 degree and 1 second delay per +/- 90 degree turn. After testing about 13 minutes, servo stopped working and not functional anymore. Battery only drained from 7.6V to 7V. I am surprised such poor reliability of this servo with such high price.
