Robbe Modellsport FS 1109 HV MG Eco Digital Servo

The FS 1109 HV MG ECO is a 20 mm standard digital servo housed in a robust, shock-resistant PE/carbon plastic housing. It features a powerful, double ball-bearing drive and a bronze metal gearbox. This servo is reliable and suitable for electric and combustion aircraft of many classes. However, it can also be used in many other areas of RC model making.
The Robbe ECO series servos are precision-manufactured high-voltage digital servos in various sizes, designed for different applications in RC model making. They feature a durable plastic housing, ball bearings, metal gears and a soft start function that moves the servo slowly and gently to the neutral position when switched on. The ECO servos offer excellent value for money, impress with their high quality and reliability, and are hard to beat in terms of versatility.
