Emax ES08MA II Servo Datasheet Write-up Overview The Emax ES08MA II 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. Key Features

Metal Gears – Alloy metal output gear and internal gears for enhanced crash resistance and longer lifespan compared to nylon gears. Coreless Motor Option – Note: The ES08MA II typically retains a standard 3-pole motor (not coreless) to keep cost low, but check vendor specifics. Dual Ball Bearings – One on the output shaft and one on the case top for smooth, friction-reduced rotation. Compact & Light – Standard micro servo size with a weight of approximately 12–13g (including wires and horn). Analog Control – Standard 50Hz PWM (Pulse Width Modulation) signal; requires a constant refresh signal.

Brown – Ground (GND) Red – Positive power (+4.8V to 6.0V) Orange – PWM signal input

Performance Notes

Torque & Gearing – The metal gear set introduces a small amount of backlash compared to nylon, but is significantly tougher under shock loads. Current Draw – Idle: 5–10 mA; Operating (no load): 100–150 mA; Stall at 6V: ~700–800 mA. Use a suitable BEC (Battery Eliminator Circuit) rated for at least 1A per servo. Center Pulse – 1500 µs ± 100 µs (standard for most RC systems). Current Draw – Idle: 5–10 mA

Typical Applications

250–450 size collective pitch heli (cyclic or tail servo – though not recommended for high-speed tail gyros) Foam board fixed-wing aircraft (aileron/elevator/rudder) Micro robotic grippers or pan-tilt mechanisms 1/24 or 1/18 scale RC car steering (light load)
