Emax Es08ma Ii Datasheet
EMAX ES08MA II is a high-performance, ultra-lightweight analog mini-servo featuring a durable metal gear train. It is widely used in small RC models, such as 250/450 class helicopters, gliders, and 1/24 scale crawlers like the Axial SCX24. Core Specifications Operating Voltage: 4.8V – 6.0V DC Stall Torque: Operating Speed: Dimensions: Technical Details Gear Type: Signal Type: Dead Band Width: Direction: Counter-clockwise / Pulse traveling Connector: JR / Futaba compatible Wire Length: Applications & Features
- Often sold singly or in multi-packs. Look for ES08MA II labeling; variants may include different wire lengths, connectors, or trimmed housings. Check seller photos/specs for exact dimensions and included accessories.
The Emax ES08MA II remains one of the best value-for-money upgrades in the hobby space. If you need a small, metal-geared servo that won't break the bank, this is the industry standard. high-voltage (HV) Emax Es08ma Ii Datasheet

Performance and Use Cases
Before diving into pinouts and timing diagrams, here are the headline specifications that define the ES08MA II. Note that "II" denotes the second generation, which features improved potentiometer linearity and a more robust control IC compared to the original ES08MA. The Emax ES08MA II remains one of the
20T spline
The ES08MA II uses a . This is important because many micro servos (like the TowerPro SG90) use a 21T or 25T spline. Futaba-style micro horns are the correct replacement. Do not force a horn from a different servo onto the ES08MA II – you will strip the soft metal spline.
