The ES08MA II offers the best price-to-performance ratio for mid-range torque applications. It’s not the strongest or fastest, but it is the most reliable in its price bracket. Part 9: Programming Example – Arduino Control For those integrating the servo into a DIY project, here is a minimal Arduino example using the built-in Servo library.

The ES08MA II is analog, so do not use a refresh rate higher than 70Hz. The Arduino Servo library defaults to 50Hz, which is perfect. Part 10: Troubleshooting Common Issues Based on user reports and Emax support bulletins, here are solutions to frequent problems:
