12. Recommended Alternatives (by application)

| Use case | Better choice than ES08MA II | |----------|------------------------------| | Higher torque (>3 kg·cm) | Emax ES3104 (digital, metal) | | Faster speed (<0.07 s/60°) | Emax ES09MD (digital, coreless) | | Lower weight (<6 g) | Emax ES9051 (micro digital) | | 7.4V operation | Blue Bird BMS-101CV (HV) |

Disclaimer: Specifications are typical for production units and may vary slightly between batches. Always test centering and torque before deploying in a critical application. For the most current datasheet, search "Emax ES08MA II datasheet PDF" or visit Emax’s official distributor pages.

2.2 Speed (No Load)

| Voltage | Speed | Unit | | :--- | :--- | :--- | | 4.8V | 0.12 sec/60° | seconds | | 6.0V | 0.10 sec/60° | seconds |

Interpretation: With a speed of 0.10 seconds at 6V, this is considered a medium-fast servo. It is not a race servo (like a 0.06 sec unit), but it is perfectly adequate for flight control surfaces on a 1-meter wingspan plane or dynamic leg movement in a small robot.
