Emax ES09MD Servo - 2.6Kg (36.11 oz in), .08-sec - 14.8 Grams Blejzyk The Emax ES09MD digital servoThe Emax ES09MD digital servo features a set of Metal Gears, high quality Noble pot, and plenty of performance for 450 Heli swash plates and other applications. Emax tells me these are designed for 450 Heli swash plate applications, but one thing I have learned over the years, a good heli servo makes for a great airplane servo too. Tough gears, good accuracy, strong torque and very quick speed, what isn't to like? As always, Emax offers great value!
