Key Features

• Waterproof Design — The servo features full waterproof construction, which means it can operate reliably even in wet conditions without risk of electrical failure or corrosion. This is essential for RC boat applications and outdoor driving in unpredictable British weather, giving you complete peace of mind when operating your models.
• 3kg-cm Torque at 6.0V — The servo delivers 3 kilogram-centimetre of torque, which provides sufficient force to control steering, throttle, and directional inputs across standard RC cars, boats and aircraft without lagging or losing responsiveness under normal operating conditions.
• Quick 0.16 Second Transit Speed — With a transit speed of just 0.16 seconds at 6.0 volts, the servo responds rapidly to your radio inputs, ensuring your control inputs translate immediately into model movement. This fast response time is crucial for precise steering and accurate throttle control, particularly in competitive driving situations.
• Plastic Gear Construction — The servo utilises plastic gearing, which is standard for budget-conscious RC enthusiasts and works excellently for typical hobby-grade applications. Plastic gears reduce weight and cost whilst still providing reliable performance for the vast majority of RC users.
• Compact Standard-Size Housing — Measuring just 40.5 x 20 x 35.6 millimetres and weighing only 37.6 grams, the ES030 is genuinely compact and lightweight, allowing integration into tight servo mounting spaces without compromising the balance or performance of your RC model.
• Futaba Compatible — The servo features the standard 25-tooth spline connector and is fully compatible with Futaba radio systems and any other radio gear using standard servo connectors, ensuring simple installation and broad compatibility across different RC setups.
• Three-Wire Configuration — As a standard three-wire servo, connection is straightforward: signal wire, power, and ground. This simplicity means quick installation and easy troubleshooting if any issues arise during setup or operation.

Technical Performance

The Etronix ES030 represents a solid engineering approach to standard servo design, prioritising reliability and ease of use over premium materials. Operating at a maximum voltage of 6.0 volts (compatible with NiMh battery packs common in RC cars and boats), the servo delivers consistent performance with its 3kg-cm torque specification and rapid 0.16-second response time. The plastic gear train is precision-engineered to handle the moderate loads typical of standard RC applications; whilst not suitable for extreme high-speed racing or heavy-duty industrial use, the ES030 excels in general hobbyist applications across RC cars, boats and aircraft. The waterproof housing utilises sealed casings and protective materials that prevent water ingress, making this servo genuinely suitable for damp environments and outdoor operation. At just 37.6 grams, the servo contributes minimal weight to your build, which is crucial for maintaining proper weight distribution and handling characteristics in RC models where every gram matters. The standard 40.5 x 20 x 35.6 millimetre dimensions ensure the servo fits within the servo bays designed into most modern RC chassis and airframe designs without modification or adaptation.
