Emax Es08ma Ii Datasheet | SIMPLE · 2027 |

While this article covers 99% of what you need, the original manufacturer’s datasheet (as a PDF) can be sourced from:

Datasheet document number: EMAX-ES08MAII-V2.1 (latest revision as of 2024)

Not recommended for: Continuous rotation applications (this is a positional servo), high-vibration engines, or sub-zero outdoor use without preheating. Emax Es08ma Ii Datasheet

One of the main selling points of the ES08MA II is its metal gear train. Let's disassemble (conceptually) the gear stages:

Compared to the nylon gears of the ES08A (plastic version), the metal gears provide: While this article covers 99% of what you

Trade-off: Metal gears transmit more vibration and are slightly noisier. They also add 2g of weight compared to the plastic version.

Note: The theoretical max range is 180 degrees, but due to mechanical stops, the useful range is typically 120-140 degrees unless modified. Datasheet document number: EMAX-ES08MAII-V2
