EMAX ES08MA II Micro Servo 12g Metal Gear Analog - for RC Models, Robot Arm, STEM, Raspberry Pi Projects
The EMAX ES08MA II is a 12-gram micro servo with metal gears and an analog control circuit that delivers 0.12 sec/60° speed at 4.8V and 1.6 kg·cm torque. Its compact footprint (23 × 11.5 × 24 mm) makes it a natural fit for tight spaces in RC airplanes, boats, cars, robot arms, and educational projects like Raspberry Pi builds. Each unit is a genuine EMAX product, backed by a 3-month quality guarantee.

Metal gears give this servo better resistance to wear than plastic alternatives, especially useful in applications where the servo is under constant load or shock. The analog circuit provides smooth, proportional movement, which is important for precise positioning in robot arms.
Which projects benefit from the ES08MA II's small size and metal gears?
The 12-gram weight and 23 mm length allow this servo to fit inside small RC models or function as a joint in mini robot arms. Hobbyists often choose it for lightweight RC planes where every gram counts, or for RC boats that need a compact steering actuator. In the STEM classroom, it works well with Raspberry Pi and Arduino kits (standard servo libraries). The metal gears also handle repeated motion better than plastic, so it suits robotic arms that cycle frequently.
What does the warranty cover?
Each servo comes with a 3-month free replacement or refund promise for any quality issues. If something goes wrong, scan the QR code included in the package to contact the seller directly. This policy applies to the original purchaser.
Four quick questions about the EMAX ES08MA II
