Stop cooking budget servos on direct 2S LiPo bus power or suffering mid-flight cyclic flutter. The EMAX ES09MD HV digital micro servo 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.
Key Highlights
Direct High-Voltage Operation: 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.
Dual Ball Bearing (2BB) Support: Dual-bearing output assembly eliminates slop and shaft play for consistent centring.
Durable Metal Geartrain: Reinforced metal internal gears and a 21T output spline withstand high cyclic loads and aggressive surface deflections.
Extended PWM Pulse Travel: Provides 90 8 operating travel across 10002000 sec, expanding to 175 10 across the full 5002500 sec pulse width range.
Why You Want It
Because 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.
