EMAX ES3352HV High Voltage Servo

The EMAX ES3352HV is a slim, high-voltage digital servo engineered specifically for fixed-wing aircraft, VTOL drones, and RC gliders. At just over 9mm thick, this flat-profile component drops easily into tight wing cavities where standard micro servos will not fit.

Key features

• High-voltage capable for direct operation from 2S LiPo receiver packs or HV BECs without a step-down regulator.
• Durable metal gear train ensures reliable torque transfer and structural resistance during hard landings.
• Ultra-slim 9.17mm profile optimised for flush mounting inside glider wings and compact airframes.
• Digital circuitry provides precise centering and crisp control surface response.

Specifications

• Operating voltage: 6.0V – 7.4V
• Stall torque: 2.4 kg·cm @ 6.0V / 2.8 kg·cm @ 7.4V
• Operating speed: 0.12 sec/60° @ 6.0V / 0.10 sec/60° @ 7.4V
• Gear type: Metal
• Dimensions: 23.17 x 9.17 x 24.05 mm
• Weight: 12.4 g

Fitted with a standard JR-style connector, the ES3352HV is a reliable drop-in upgrade for builders demanding high actuation torque and precision in a space-constrained layout.
