The \u003cstrong\u003eEMAX ES09MD\u003c\/strong\u003e is a dedicated digital mini servo engineered specifically for 450-class RC helicopters, packing metal gears, dual ball bearings, and a genuine NOBLE potentiometer into a compact 14.8g casing. Backed by our 10 years of experience in the manufacturing and delivery of commercial FPV systems and precision RC hardware, we know that slop in your swashplate linkage ruins flight controller stabilisation and tail authority. Whether you are dialling in aggressive 3D collective pitch manoeuvres or fine-tuning flybarless gyro responsiveness, the ES09MD provides repeatable centring, high holding torque, and zero unwanted backlash right out of the box.\u003c\/p\u003e\n\u003ch3\u003eKey Highlights\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDual-Bearing Output Shaft:\u003c\/strong\u003e Large-diameter shaft supported by dual ball bearings eliminates linkage play and ensures smooth cyclic control.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReinforced Metal Gear Set:\u003c\/strong\u003e High-hardness gear architecture maximises transmission efficiency and prevents stripped teeth under sudden collective pitch spikes.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrecision NOBLE Potentiometer:\u003c\/strong\u003e Delivers ultra-tight signal coherence and reliable centring accuracy across thousands of dynamic flight cycles.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh-Speed Digital Performance:\u003c\/strong\u003e Actuates down to 0.08 sec\/60° at 6.0V for lightning-fast gyro correction loops and razor-sharp swashplate response.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWhy You Want It\u003c\/h3\u003e\n\u003cp\u003eBecause stripping nylon gears mid-tick-tock turns your expensive 450 build into lawn dart debris faster than you can flip throttle hold. The EMAX ES09MD is built to endure the brutal cyclic loads of CCPM swashplate setups without developing the dreaded deadband wobble that haunts budget servos. It gives you snappy 2.6 kgf.cm holding torque at 6.0V, paired with the exact pulse timing your flybarless system demands. Yes, we want your money, but we also want you spending your weekends flying inverted rather than rebuilding servo geartrains on your workbench.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperating Voltage:\u003c\/strong\u003e 4.8V – 6.0V\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSTD Direction:\u003c\/strong\u003e Counter-Clockwise \/ Pulse Travelling 1500 to 1900 µsec\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStall Torque (4.8V):\u003c\/strong\u003e 2.3 kgf.cm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperating Speed (4.8V):\u003c\/strong\u003e 0.10 sec\/60° at no load\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStall Torque (6.0V):\u003c\/strong\u003e 2.6 kgf.cm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperating Speed (6.0V):\u003c\/strong\u003e 0.08 sec\/60° at no load\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 23.0 × 12.0 × 24.5 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 14.8g\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlug Type:\u003c\/strong\u003e FUT \/ JR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGear Type:\u003c\/strong\u003e Metal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eServo Type:\u003c\/strong\u003e Digital\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0914\/9972\/5181\/files\/EMX-SV-0287-DES-1.webp?v=1786961241\" alt=\"\"\u003e\u003c\/p\u003e\n\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003ch4\u003eCan I use the EMAX ES09MD as a direct drop-in replacement on cyclic swashplate linkages for 450-class helicopters?\u003c\/h4\u003e\n\u003cp\u003eYes.
