The \u003cstrong\u003eEMAX ES09MD HV digital micro servo\u003c\/strong\u003e delivers high-voltage performance and dual-bearing precision for demanding 450 helicopter swashplates, fixed-wing linkages, and pan-tilt mechanisms. Backed by our 10 years of experience in the manufacturing and delivery of commercial FPV systems, we know how PWM jitter, stripped geartrains, and voltage drops ruin flight controller PID stabilization. Packing a 21T spline, metal gears, and 3.1 kg.cm of stall torque at 8.4V into a featherweight 13.5g case, this digital actuator gives you razor-sharp response without requiring bulky external step-down regulators.\u003c\/p\u003e\n\u003ch3\u003eKey Highlights\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDirect High-Voltage Operation:\u003c\/strong\u003e Runs natively from 6.0V up to 8.4V, generating up to 3.1 kg.cm stall torque and 0.12 sec\/60° transit speed without an external BEC.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDual Ball Bearing (2BB) Support:\u003c\/strong\u003e Dual-bearing output assembly eliminates slop and shaft play for consistent centring.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDurable Metal Geartrain:\u003c\/strong\u003e Reinforced metal internal gears and a 21T output spline withstand high cyclic loads and aggressive surface deflections.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended PWM Pulse Travel:\u003c\/strong\u003e Provides 90° ± 8° operating travel across 1000–2000 µsec, expanding to 175° ± 10° across the full 500–2500 µsec pulse width range.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWhy You Want It\u003c\/h3\u003e\n\u003cp\u003eBecause stripping nylon servo gears on an aggressive cyclic roll or sending your aircraft into the turf due to voltage sag is an expensive hobbyist headache. The EMAX ES09MD HV handles direct 8.4V bus lines with a 9.5mA idle draw, delivering 3.1 kg.cm of high-voltage holding torque when your gyro demands instant correction. Yes, we obviously want your money, but we would much rather you spend your flight sessions ripping clean lines instead of fishing stripped plastic gear teeth out of your airframe.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 13.5 ± 1 g\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperating Voltage:\u003c\/strong\u003e 6.0V – 8.4V\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperating Speed (at no load):\u003c\/strong\u003e 0.17 sec\/60° (6.0V) | 0.12 sec\/60° (8.4V)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRunning Current (at no load):\u003c\/strong\u003e 200mA Max (6.0V \u0026amp; 8.4V)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStall Torque:\u003c\/strong\u003e 2.3 kg.cm Max (6.0V) | 3.1 kg.cm Max (8.4V)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Current:\u003c\/strong\u003e 0.65A Max (6.0V) | 0.9A Max (8.4V)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIdle Current:\u003c\/strong\u003e 9.5mA (6.0V \u0026amp; 8.4V)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBearing:\u003c\/strong\u003e 2BB (Dual Ball Bearing)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGear Type:\u003c\/strong\u003e Metal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutput Gear Spline:\u003c\/strong\u003e 21T (Ø4.95 ± 0.05 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnector Wire Gauge \u0026amp; Length:\u003c\/strong\u003e JR, 250 ± 8 mm (without connector)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eControl System:\u003c\/strong\u003e PWM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeutral Position:\u003c\/strong\u003e 1500 µsec\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePulse Width Range:\u003c\/strong\u003e 500–2500 µsec\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperating Travel:\u003c\/strong\u003e 90° ± 8° (1000–2000 µsec) | 175° ± 10° (500–2500 µsec)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRotating Direction:\u003c\/strong\u003e Counter Clockwise \/ Pulse Traveling 1500 to 1900 µsec\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtreme Angle:\u003c\/strong\u003e 360°\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperating Temperature Range:\u003c\/strong\u003e -10°C to 50°C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStorage Temperature Range:\u003c\/strong\u003e -20°C to 60°C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 23.20 × 12.00 × 24.50 mm (27.60 mm total height with spline, 32.00 mm mounting ear span)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0914\/9972\/5181\/files\/ES09MDHV.webp?v=1776252975\" alt=\"Technical drawing and specifications of a product with dimensions and tolerances.\"\u003e\u003c\/p\u003e\n\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003ch4\u003eWhat pulse width range and travel does the EMAX ES09MD HV support?\u003c\/h4\u003e\n\u003cp\u003eThe EMAX ES09MD HV operates on a standard 1000–2000 µsec PWM pulse for 90° ± 8° of travel, and extends to a maximum travel of 175° ± 10° when driven across a 500–2500 µsec pulse width range.\u003c\/p\u003e\n\u003ch3\u003eWhat’s in the Box*\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1× EMAX ES09MD HV Digital Micro Servo with JR Lead (250mm)\u003c\/li\u003e\n\u003cli\u003eAccessory Pack: Data unavailable (the manufacturer blueprint focuses strictly on raw engineering dimensions, though standard horn and screw packs are typically provided in retail packaging).\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eDisclaimer\u003c\/h2\u003e\n\u003cp\u003eAll technical specifications are pulled directly from the manufacturer engineering drawing (V1.2).
