MKS DS75K-R Wing Servo – 2.4Kg.cm 0.13s 7.8g 9mm

The MKS DS75K-R servo is the wing mount version of the DS75K servo from MKS. The case has horizonal mounting tabs making it suitable for fitting in a wing (or tail surface).

The MKS DS75K-R is more powerful, faster, and considerably more robust than the DS65K. It is also rated for operation down to 3.5V making it safe for use on 1S LiPo batteries. Its clever inverted motor design makes it very compact, in fact is is nearly as small as the SD100/D47 in the vertical and horizontal directions.

The DS75K-R is ideal for F3K, F5K, F5D, and all small models that require excellent precision, massive torque, and adequate speed. Along with the DS65K it is probably the best 9 mm thick servo currently produced. It looks beautiful and with a torque of 2.4 Kg cm it is amazingly powerful.

The MKS hallmark CNC aluminium alloy case adds rigidity and crash resistance to the servo. The gears are pre-loaded to remove all slop or backlash from the geartrain, allowing a level of precision unequalled by other manufacturers.

The extreme reliability and performance of these servos also makes them very suitable for use in film and motion picture industry special effect departments. They are also used in robotic, drone, UAV, UAS, academic research, military, and other highly demanding applications.

Low/standard voltage versions of the DS75K are available with standard mounting lugs (the DS75K), wing mounting lugs (the DS75K-R), and no mounting lugs (the DS75K-N). High voltage versions are available with standard mounting lugs (the HV75K), wing mounting lugs (the HV75K-R), and no mounting lugs (the HV75K-N).
