FS 4009X HV MG Digital Servo

The Robbe FS 4009X is an extremely powerful and robust servo housed in a compact, CNC-machined aluminium housing with cooling fins for better heat dissipation. It features a stable, backlash-free metal gearbox and ball bearings on the output shaft. With an impressive holding force of 32 kg/cm at 8.4 volts and a short response time, it is extremely versatile – whether in various types of aircraft for all control surfaces, in RC cars or boats. The FS 4009X is therefore an excellent choice for long-lasting and reliable control in many applications.

The new Robbe X-series servos are precision-manufactured high-voltage digital servos in various sizes, suitable for different applications in RC model making. They feature CNC-machined aluminium housings with cooling fins for better heat dissipation and robustness, metal or steel gears for low backlash and high positioning accuracy, high-quality ball bearings, bell-type or brushless motors and a high degree of protection against external influences (IP56). In addition, they are equipped with a soft start function that moves the servo slowly and gently to the neutral position when switched on. These features ensure a long, reliable service life for the servos and thus also for the safety of your models.
