Product Overview Engineered for heavy – vibration, long – cycle outdoor RC and robotic operations, EMAX RC Servos minimise gradual performance drift triggered by component wear, mechanical flex and complex wiring setups. Featuring non – contact magnetic encoder feedback, wide – voltage compatibility and robust all – metal build, they maintain stable angular output under continuous vibration and heavy loading. With true 360°positional control, they fit seamlessly into existing assemblies without major rework, delivering dependable performance for high – demand aircraft, helicopter and robotic projects. Feature Non – contact magnetic encoder sustains stable angle output over long runtime, resisting performance variations caused by airborne vibration Wide high – voltage support delivers improved torque and response, eliminating extra onboard conversion hardware for high – voltage Li – Po power systems All – metal gears and housing withstand impact and sustained load, extending service life in harsh field operating conditions Configurable 180° / 360° positional hold expands mechanical layout flexibility, reducing modification work on linkages and gears Standard form – factor, JR connector and 23T spline support easy hardware upgrade without full – system rework Application Scenarios RC helicopter tail assemblies Large-size fixed-wing aircraft main control surfaces High-torque radio-controlled model platforms Robotic joint assemblies and motorized rotating turntable mechanisms Custom automation hardware and special – purpose RC equipment Specifications Specification ES9054Ⅱ Product Type Magnetic Encoder / Brushed / Digital / Metal Servo Operating Voltage 6.0 – 8.4V Speed(6.0 / 7.4 / 8.4V) 0.12 / 0.10 / 0.09 sec/60° Stall Torque(6.0 / 7.4 / 8.4V) 18 / 22 / 25 kgf·cm Stall Current Approx.4.0 – 5.5A (typical reference range) Net Weight 72 ±1g Dimensions Approx. 40 × 20 × 38.5 mm Rotation Angle 180°±2°, supports 360° full – range positional control Use For Mid – high torque aircraft and robotic projects prioritizing quick reaction Package List 1 × Servo Unit Servo Horns & Mounting Hardware Kit User Instruction Manual FAQ Q: Will a magnetic encoder RC servo work with my existing standard PWM receiver? A: Yes. These Emax RC Servos comply with standard 500 – 2500μs PWM and JR connector specs. Basic operation requires no special controller. Only 360° position mode needs corresponding controller parameter configuration. Q: What real-world improvement does a magnetic encoder bring over potentiometer-based RC servos during flight? A: Potentiometer-based servos tend to develop positional offset under sustained vibration and long flight time. Magnetic encoder maintains stable centering over long-term use and cuts frequent in-flight trimming. Q: Can I power this high – voltage radio control servo using a 2S LiPo battery? A: It works with lower – voltage input but cannot reach full rated performance. Make sure your BEC or power supply provides sufficient current for actual working loads. Q: How will large outdoor temperature fluctuations affect servo performance? A: It supports broad ambient temperature ranges for outdoor use. Avoid continuous operation under extreme temperatures to preserve service lifespan. Q: Is regular calibration needed after hard crashes or heavy impacts? A: Manual calibration is unnecessary after ordinary impacts. If shaking or position offset occurs following severe crashes, check linkages, servo horns and mounting parts for mechanical damage first.
