Emax Es08ma Ii Datasheet May 2026

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.

For CAD designers and 3D printing enthusiasts, exact dimensions are non-negotiable. Below are the precise measurements (in millimeters) for the Emax ES08MA II.

** Included Horns:** The servo ships with a 4-point star horn (cross), a round horn, and a single-arm horn. The spline is a standard 21T, compatible with Futaba and many FrSky accessories. Emax Es08ma Ii Datasheet

| Pulse Width | Angle | Position | |-------------|-------|----------| | 1000 μs | 0° | Full counter-clockwise (CCW) | | 1250 μs | 45° | | | 1500 μs | 90° | Neutral / center | | 1750 μs | 135° | | | 2000 μs | 180° | Full clockwise (CW) |

Range Adjustment: The ES08MA II’s mechanical stops allow approximately 200° of total travel, but the linear control range is 180° (1000-2000 μs). Do not send pulses below 800 μs or above 2200 μs to avoid damaging the internal potentiometer. Speed:

Connect servo V+ to 5V, GND to Arduino GND, signal to a PWM-capable digital pin. Example Arduino usage (Servo library):

#include <Servo.h>
Servo s;
void setup() 
  s.attach(9); // pin 9
void loop() 
  s.write(90); // move to center
  delay(1000);
  s.write(0);
  delay(1000);

| Voltage | Torque (oz-in) | Torque (kg-cm) | | :--- | :--- | :--- | | 4.8V | 21.7 oz-in | 1.6 kg-cm | | 6.0V | 25.0 oz-in | 1.8 kg-cm | Deadband: ~5–10 µs (typical for analog micro servos)

Interpretation: 1.8 kg-cm is respectable for a 13-gram servo. This means the servo can hold a weight of 1.8 kilograms at the end of a 1 cm horn. Practically, for a 5 cm horn, it can lift roughly 360 grams. This is ideal for small robotic grippers or micro RC car steering.

Datasheets often depict best-case scenarios. Here is what users actually report in real-world applications like RC planes, battle bots, and animatronics.

While the datasheet provides typical values, real-world performance depends on load and temperature.
