Emax Es08ma Ii Datasheet [verified] Jun 2026
The compact build allows it to fit directly into the pre-cut servo slots of fixed-wing RC planes, micro helicopters, 1/24-scale RC crawlers (such as the Axial SCX24), and small robotic joints. ES08MAII 12g Metal Gear Servo - Rotor Riot
The is an upgraded version of the popular ES08MA analog micro servo. It is distinguished by its metal gear train and carbon-brush motor, offering a balance of torque, speed, and durability for its size. This "II" revision typically features improved potentiometer stability and slightly refined tolerances over the original. It is widely used in micro RC aircraft (e.g., 250-450 size helicopters, foamies), lightweight robotics (walking robots, robotic arms), and small-scale DIY projects.
When to look elsewhere:
The (or ES08MAII) is a popular, high-performance, 12-gram mini analog metal gear servo, often referred to as the V2 of the original ES08MA. It is widely used in RC planes, helicopters, micro-crawlers, and hobby robotics due to its balance of durability, high torque, and low price.
Standard direction is counter-clockwise with a pulse travel of 1500 to 1900 µsec. Some sources indicate an extended range of 160° to 180° depending on the pulse width (500–2500 µsec). High Sensitivity: Emax Es08ma Ii Datasheet
The form factor of the ES08MA II is classified as a "micro" servo. It shares a footprint similar to the ubiquitous SG90 plastic servo but is slightly deeper to accommodate the metal gear train.
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. The compact build allows it to fit directly
The ES08MA II is widely compatible with most receivers (FUT/JR plugs). It is a "standard" upgrade for the Axial SCX24 community, frequently paired with the INJORA Aluminum Servo Mount for a rock-solid steering setup. ⚠️ Pro-Tips for Your Build Mind the Voltage:
While detailed technical datasheets for the original "ES08MA I" can be difficult to find, user experiences and seller descriptions point to the "II" being an enhanced version. The most significant difference is understood to be a . The "II" model was designed to provide greater durability and higher resistance to shock and wear compared to its predecessor. For most users, the "II" is the recommended choice for its improved robustness. It is widely used in RC planes, helicopters,
