Emax Es08ma Ii: Datasheet

The Emax ES08MA II is a第二代 (2nd Generation) analog micro servo. It is an upgraded version of the popular ES08A, featuring a metal gear train for increased durability and torque transmission. It is widely used in small to medium RC models (airplanes, helicopters, cars, robots) and lightweight industrial projects.

Key distinguishing feature: Full metal gears (aluminum alloy) replacing the nylon gears of the standard ES08A, providing higher crash resistance and precision.

Notes: Values above are typical ranges reported across EMAX ES08MA II product listings and hobbyist testing. Exact figures depend on production batch and testing method. Emax Es08ma Ii Datasheet
