FS 2108X HV MG Digital Servo

The Robbe FS 2108X is an extremely powerful, robust and flat surface servo housed in a compact, CNC-machined aluminium housing with cooling fins for better heat dissipation. It has a stable, backlash-free metal gearbox and ball bearings on the output. The FS 2108X impresses with an extremely high torque of 21 kg/cm at 8.4 volts and a very short response time. This makes it particularly suitable for use in 3D and aerobatic models in the 60-78 inch class, especially for all control surfaces. It is also an excellent, weight-optimised alternative to standard servos in large models or jets.

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.
