The EMAX ES09MD HV is a high voltage digital servo built for RC aircraft, gliders, and applications where standard 4.8–6V servo voltage isn't enough. HV operation lets it run directly off 2S LiPo or LiFe receiver packs without a voltage regulator, delivering faster speed and higher torque than the same servo at standard voltage. Metal gear construction handles the repeated load cycles of control surface deflection without the wear that strips nylon, and the digital circuit provides tighter centering and better holding torque than analog equivalents. A reliable, high-performance servo for pilots who demand more from their control surfaces.
High voltage (HV) operation — runs directly off 2S LiPo or LiFe packs for faster speed and higher torque
Digital circuit — tighter centering, better holding torque, and faster response vs analog
Metal gear train — durable under repeated load cycles, resists stripping
No voltage regulator needed — simplifies wiring for HV receiver setups
Versatile applications — RC aircraft, gliders, sailplanes, and precision control surface builds
More voltage, more torque, more speed — the ES09MD HV is the upgrade for pilots running high voltage receiver systems.
