Emax ES09MD HV Metal Gear Digital Servo

Overview:
The Emax ES09MD HV Metal Gear Digital Servo is a compact high-voltage servo designed for RC applications where reliable, precise control is needed in a small package. It uses digital control circuitry and a robust metal gear train to deliver responsive movement and improved durability compared to entry-level analogue servos. With an expanded operating voltage range up to 8.4V, this servo can be powered directly from 2S LiPo systems, making it suitable for light aircraft, micro cars, lightweight boats and robotics projects where space and weight are at a premium.

This servo offers a balance of speed, torque and compact dimensions that make it a useful drop-in option for models that require reliable actuation without the cost or weight of larger servos.

Features:
- Digital control system provides precise position holding and faster response than analogue units.
- Metal gear train improves strength and wear resistance under load.
- High-voltage compatibility means the servo can be powered from 5V up to 8.4V, including 2S LiPo setups.
- Dual ball bearings reduce internal friction and support smooth rotation.
- Compact size and lightweight construction make it suitable for tight spaces and weight-sensitive builds.
